Before the human era, New Zealand was a highly isolated world
of flora and fauna. The oldest representatives of the fauna of the Earth persisted
here, and the endemism of animals was manifested at the order level. Only New
Zealand harbored birds of kiwi and moa orders, as well as reptiles of Rhynchocephala
order. Other animal species were also represented mostly by endemic genera and
families. After the human colonization of the islands, the appearance of New
Zealand nature has changed beyond recognition. People exterminated giant birds,
and instead of them, mammals from various parts of the Earth appeared on the
islands. Among the newcomers to New Zealand there were hedgehogs, stoats, possums,
deer, as well as numerous species of European, American and Australian birds.
In addition to these, various domestic animals have appeared in New Zealand.
The aliens caused irreparable damage to the unique flora and fauna of the islands.
People tried to restrain their numbers for some time, but failed to take control
on them completely. With the extinction of humankind, the only deterrent to
the reproduction of outsiders disappeared, and they began to settle actively,
destroying the primordial types of natural communities that had been formed
in completely different conditions for millions of years. After a short period
of instability, the destroyed original ecosystems, hitherto rich and diverse,
were replaced by new ones, poor in species diversity, but stable in the changed
conditions. The evolution of the introduced mammals and birds continued in a
new place, and they became a natural part of the emerging natural communities.
In the epoch of the ecological crisis, a large number of endemic New Zealand
species disappeared, and in the Neocene, the descendants of local species represent
only few species in the fauna of New Zealand. One of the most successful species
of the Neocene fauna of the archipelago descended from the flightless weka rail
(Gallirallus australis). This is the ruakapangi, a large carnivorous bird, one
of the top predators in the ecosystems of New Zealand and the largest native
bird.
The ruacapangi nest is arranged on the ground among dense bushes, and prying
eyes are unlikely to notice it. It is a simple hole that both parents dug together.
The inside of the nest is lined with dry fern leaves and down, which the female
plucked from her own chest and belly during the hatching. Three large eggs with
a smooth mottled shells lie among the nest litter. Due to the shell coloring,
they actually do not stand out against the background of the nest, and they
are more difficult to notice to a random predator. The ruacapangi female usually
stays on the nest and moves away from it for a short time only to stretch her
legs, which are numb from immobility. Now she needs to be especially caring
and attentive – the incubation period is coming to an end, and the chicks should
hatch very soon. Two of the eggs are trembling a little – the chicks inside
them are well-developed and ready to see the light within the next few hours.
The third egg lies motionless among the litter.
Ruacapangi female approaches the nest. This bird has a camouflage plumage color
– it is brown with longitudinal black strokes on the feathers. The bird has
no wings – they have completely disappeared already in its ancestor during the
human era. The plumage of ruacapangi looks more like wool – the barbs of the
feathers do not form a dense vane, and the feather shaft is soft and flexible.
The head is covered with bare red skin from the front and sides. A large sharp
beak shows that this bird is a predator capable of killing large animals. This
beak has taken the lives of many prey items, but now the bird is very carefully
touching the eggshells with it. It is the mother of unborn chicks, a female
named Harpy.
The night passes anxiously. The male is named Sharpbeak, the father of the unborn
chicks, left in the evening, and has not yet returned. He often went hunting
at night, and during the day he replaced the female on the nest, giving her
an opportunity to hunt and to have some rest. The most important change in the
life of birds is that Harpy began to distinguish two voices clrearer and clearer
in the silence of the night. They were unfamiliar to her, but the female understood
that she had long wanted to hear them. And it looks like a little miracle is
about to happen in the life of this pair of birds.
Early in the morning, when abundant dew appeared on the tree leaves and fern
fronds, Harpy heard a faint crunch, after which a quiet squeak became much clearer.
She carefully raised her body above the nest, and looked at her clutch. Two
eggs were moving, and there were several pieces of shell lying among the litter,
clearly distinguishable because of their white underside. Each of these eggs
was cracked, and tiny grayish beaks protruded from the holes. From time to time
the beaks hid inside the eggs, and sometimes they stuck out even more. After
looking at the hatching chicks, the ruacapangi female fluffed up and continued
the hatching. The warmth of her body stimulated the chicks’ attempts to free
themselves from the shells. Each of the chicks, turning gradually inside the
shell, punched the shell in a circle with its beak, dividing it into two halves.
Then one of the chicks tried to straighten up, resting its feet on one half
of the shell, and its head against the other one. The shell fell apart into
two halves, and the chick crawled out of it into the nest litter. Later, the
second chick broke free of the shell. There are two chicks in the brood of Harpy
and Sharpbeak – Fidget, the male hatched earlier, and Motley, the female appeared
after him, who inherited speckled fluff on her stomach from her mother and grandmother.
Right now, ruacapangi chicks look little like adult birds: they are black, and
the skin on their heads is completely covered with down. Only by the time the
plumage grows, the down will begin to fall out, and the skin on the front of
their heads will be as bare as at their parents. The first minutes of their
life, future predators are completely helpless: they are weak, wet, and are
unable not only standing on their feet, but even just raise their heads. They
hatched with their eyes open, but so far there is little use of sight – the
chicks keep under the plumage of their mother, and can only hear her. They gradually
dry out and become fluffy. The hatching took a lot of work, and now the chicks
are resting. So far, they have not actually seen their own mother, although
they constantly feel her presence. The image of the mother for them is composed
of the warmth of her body, measured breathing and her heartbeat. The chicks
are warm, and they are moving more and more actively. From somewhere above,
the Harpy’s voice is heard, which they also remember and add to the image of
their mother that is being formed at these moments.
Footsteps are approaching from somewhere in the distance. The chicks do not
hear them because of the mother’s thick plumage, but they feel them through
the soil. And then two voices were heard at once, one of which was the familiar
voice of the mother, and the second was unfamiliar, but similar to it. Chicks
instinctively know how to recognize danger signals characteristic of their species,
but this time they do not hear danger and do not worry. And then the world they
had known for only about an hour changed dramatically.
Harpy, who had been warming the chicks diligently, stood up. Two small chicks,
covered with black down, were huddled at her feet. The world that suddenly opened
up in front of them was so huge that it scared them. Two chicks saw the sunlight
penetrating through the forest canopy for the first time. And they managed finally
to see their own mother from the outside. Harpy carefully bent down to them
and run over the head of Motley with the tip of her beak, and then touched the
back of Fidget with the bare skin of the side of her head. The mother herself
looked at her chicks, imprinting their image. Then she uttered a sound like
a soft cooing, and the chicks responded to it, peeping a due voci. The connection
between the female and her offspring established gradually. The chicks imprinted
the appearance of their mother, which is firmly associated now with things they
learned about her earlier – warmth and voice.
Next to the nest, another bird wanders, similar to the mother, but different
in voice and behavior. This bird looks a little taller than their mother. Moreover,
Harpy does not show aggression towards it, because this is her mating partner
and the father of two chicks – the male named Sharpbeak. This pair of birds
has been keeping together for several years and has successfully raised several
young birds. Dangerous predators can be gentle and loving parents. Sharpbeak
shows caution, when walking near the nest. He also eyes the chicks thoughtfully,
memorizing their voices and appearance. But when he tried to get closer, Harpy
snapped her beak, and Sharpbeak took a step back. If it seems to the female
that the male shows aggression to the offspring, she can attack him. The ruacapangi
family is dominated by the female, and Sharpbeak does not try to argue against
Harpy.
The primacy of the female in this species manifests itself almost from an early
age. The chicks sat in the nest under the female for several minutes tried to
get to their feet. Motley is a little stronger than Fidget is. She tries to
get to her feet, rising up among the nest litter, but totters and sits down
again. Fidget is also trying to stand up, but his attempt appears even worse
– he falls into the litter. However, he does not stop trying to stand up – he
makes another effort, and with difficulty rises to his feet.
Chicks signal their parents about their needs with a loud squeak. Harpy and
Sharpbill are experienced parents, and they know that the chicks need to be
fed. For the first few days, ruacapangi chicks do not know how to eat on their
own, and their parents feed them from their beaks. Before hatching the chicks,
Sharpbill did not wander aimlessly through the forest. He tried to make his
contribution to the rearing of offspring, and therefore hunted until he got
a large enough victim – he ambushed a castle
rabbit near its feeding tunnel, and brought its meat in his stomach. Sharpbeak
opened his beak slightly, made several convulsive movements with his head, and
regurgitated a small piece of rabbit meat. This piece is quite large for one
chick to swallow, but the parents know how to feed their offspring. Harpy carefully
takes it in her beak and brings it to the chicks staying in the nest. This is
their first meal in the new world that greets them. For a while, young birds
will be able to hope that their parents will feed them, but they will gradually
grow up and learn how to get food independently. So far, they don’t even know
how to eat. Harpy holds a piece of meat in the very tip of her beak, and carefully
brings it to the chicks. Fidget does not react to this act of the female, and
Motley only looks, but does not try to do anything. Then Harpy just touches
with a piece of meat to the Fidget’s beak. The chick tasted blood and meat,
and tried to peck it. Seeing that her brother tried to eat, Motley also decided
to peck the meat. She poked it with her beak, lost her balance, and fell into
the nest litter. Turning over and struggling to her feet, she pecked again and
clung to the meat with her beak. Twitching her head, Motley tore off a piece
and swallowed it. Fidget pulled the meat towards him, managed to tear off a
piece, and fell with it to the bottom of the nest. At this time, Motley, who
was standing next to him, simply snatched the meat from his beak and swallowed
it. She learned to eat in the first hours of her life, and expressed immediately
her more aggressive temper – this is a trait she inherited from her grandfather,
a large male who dominated family relationships, which occasionally happens
in ruacapangi reeding pairs. Fidget does not give up – he felt the taste of
blood and meat, and his desire took shape: he wants to eat. The young male struggled
to his feet and tried to tear off the meat again. Harpy brought the meat to
his beak and Fidget hold on it. He yanked, tore off a piece, and swallowed it
hastily. Nevertheless, even at such a young age, without seeing his first sunset
in life, he is forced to yield to the onslaught of his more aggressive sister.
Motley eats more actively, but quickly eats up, and settled down into a sleep.
So Fidget calmly eats the remains of the meat that his mother holds in her beak.
Then Sharpbeak regurgitated another piece, larger than the previous one. He
carefully gave it to Harpy, and she swallowed it. After feeding the chicks and
satisfying her own hunger a little, Harpy sits on the nest again, and Motley
and Fidget hide under her side and warm up.
The chicks spend several days in the nest. The parents take turns staying with
them – one of the adult birds must hunt to provide the offspring with food.
Ruacapangi has strong family ties, and the male takes the same part in raising
the brood as the female. In the second day of life, the chicks learn to walk.
Ruakapangi hunts by chasing its prey, so it is vital for small chicks to learn
to be fast. Fidget learns walking, which is difficult for them, faster than
Motley. The chick’s legs are disproportionately large in relation to the body
size, and the chicks have to tinker a little to master the wisdom of such a
simple thing as walking. While walking, the chicks sometimes step on their toes
and fall on the nest litter. Fluff and plant litter soften the fall, but all
the same the chicks have a hard row to hoe. Here Fidget has the opportunity
to overtake Motley in development – he is the first to take some steps in succession
without stumbling. Motley begins walking later then him. They do in under the
supervision of Sharpbeak, and Harpy hunts at this time.
When Harpy returned from hunting, the chicks had already fully mastered such
a complex method of movement. Sharpbeak was the first to pay attention to the
rustle of the foliage of ferns somewhere in the distance. He straightened up,
looked around, and made a short summoning call. If this is some kind of predator,
the ruacapangi male is ready to defend his offspring with all the fury he is
capable of. But when he heard a familiar voice in response, he immediately calmed
down and even began to preen the plumage. When Harpy appeared near the nest,
Fidget and Motley ran to meet her, begging for food. The female did not see
how the chicks learned to walk, and is in no hurry to feed them. But the voice
of the chicks helps her to recognize her own offspring, and after a little confusion,
Harpy begins to feed them. She regurgitates the meat and holds it in her beak,
and the chicks try to get it. Now they are more active than on the first day
of life. Fidget immediately pulls out a piece of meat from Harpy’s beak and
runs away, and Motley rushes after him, trying to take away this meat. But Harpy
regurgitates the meat again, and the second portion goes to the Motley. Meanwhile,
Fidget hid with his food among the ferns. He got a rather large piece, but he
does not want to share it with Motley. Fidget presses the meat to the ground
with his paw and tears off small pieces from it. And then he picks up the remaining
meat, and tries to swallow it whole. The chick needs to try pretty hard to do
this – the piece is quite large for his beak. But it does not stop him, and
Fidget begins a real battle with his own food. The meat hardly passes into the
esophagus, and Fidget has to spit it out several times, and then try to swallow
it again. Eventually he swallows the meat, twitching his neck.
After a few days, the chicks became very active and mobile. Parents are finding
it increasingly difficult to keep them in place, and they realize that it’s
just a proper time to leave the nest. So one morning Harpy just moved away from
the nest and called the chicks to her. Fidget and Motley rushed to her, and
their mother led them farther and farther away from the nest. And the male followed
the chicks, urging them on if they lagged behind or ran away to the side.
The world in which Fidget and Motley hatched is a world where the descendants
of animals introduced by people rule. In New Zealand of the Neocene epoch there
are numerous and diverse land mammals – from small creatures to true giants.
Large herbivores and large predators on the islands are also mammals. In this
world, of course, there are descendants of ancient New Zealand species, although
there are significantly fewer of them. Ruacapangi is just one of these species.
From the first day of life, ruacapangi chicks can fall prey of numerous local
predators, and even an adult bird cannot feel safe – some inhabitants of the
islands pose a threat to ruacapangi. Nature has endowed these birds with many
useful qualities that allow them to get food and escape from enemies successfully.
Ruacapangi has a strong slightly curved beak, with which the bird inflicts deep
wounds on the prey or aggressor, sharp eyesight and good hearing, allowing it
to recognize prey or an enemy from afar, and fast legs, providing the bird with
good speed when hunting or escaping from a predator. But these qualities help
only those who know how to use them, and ruacapangi chicks rely entirely on
their parents for everything so far. Nevertheless, they actively explore the
world around them, in which, if they are lucky, they will have to live for many
years.
Fidget and Motley, left in the care of their mother, wander through the grass.
They are looking for a variety of insects, and willingly peck them – this is
not a bad food for small chicks, and hunting insects helps to develop hunting
skills. But insects alone cannot satisfy the appetite of the chicks, and they
have to wait for their parents to nourish them with meat. However, some animals
that live on the ground could well become prey even for such inexperienced hunters
as week-old ruacapangi chicks.
A very large snail is crawling among the ferns. It moves slowly through the
vegetation, looking for food with its head stretched out like a proboscis. It
feeds on mushrooms and sappy tubers of plants, but if possible, it willingly
eats small burrowing animals. Thanks to its keen sense of smell, this snail
can find a worm or a grub at a shallow depth in the thickness of the ground.
The shell of this animal is very noticeable – rounded black markings are scattered
on a shiny white background. Such coloring cannot go unnoticed, and it attracts
ruacapangi chicks very much. When they see it, they immediately decide to get
to know this creature better. Motley and Fidget have never seen such animals
before, and they are scared a little of the moving tentacles of the snail. They
approach it with some caution, and begin to observe this creature, not risking
getting close. The snail does not see them – its eyesight is very poor, and
it can hardly distinguish even the objects closest to it. But its sense of smell
told her that there were two living beings nearby. It continues to search for
food, and its slow movements do not inspire ruacapangi chicks with fear. Therefore,
Motley and Fidget decide to come even closer to it. When Fidget appeared next
to the snail’s head, it slightly retracted its tentacles. Living and moving
things attract future predators, so Fidget tried to peck the snail. In response,
the snail retracted its tentacles and at the same time its shell moved slightly.
The chicks were frightened by this movement and ran away to the side. They walk
cautiously near it, not daring to approach the snail again. Having made sure
that there was no danger yet, it stretched out its tentacles again and crawled
on. Then Fidget decided to peck it again. Perhaps, a weak chick’s beak can scratch
the solid shell of a snail. Someday, in a year or more, it will be strong enough
to break the skull of prey, but so far even the snail’s shell turns out to be
an indestructible barrier for a young predator. Motley is also interested in
the snail, and the chicks have already begun to drum on its shell with their
beaks together. In response, the snail hid, firmly pressing the edges of the
shell against the ground. But the chicks noticed where it had gone and tried
to get it out of there. Fidget stuck his beak under the shell from the side,
and with a little effort turned the shell sideways. There is no protective lid
on the shell of this snail species, and the creeping sole of the snail appeared
uncovered for some time. This was immediately taken advantage of by Motley,
who managed to peck the body of the mollusk. And in response to her attack,
the snail released a copious foamy liquid, and a sharp garlic smell spread in
the air. The chicks felt it, but so far they were too inexperienced to understand
what exactly this strange creature with such a noticeable coloration was signaling.
Having no idea what ways various living creatures can defend themselves, the
chicks decided to check whether the substance produced by the snail was edible.
Motley and Fidget took turns pecking at the foam, and they both immediately
received the first lesson in their lives – their mouths began to burn unbearably
from snail secretions. Trying to do away with this terrible feeling, the frightened
chicks began to peck the ground and spit it out. Nevertheless, the unpleasant
feeling still remained and reminded of itself for many hours after their meeting
with the snail. While the chicks were trying to do away with the burning sensation,
the snail calmly poked out of the shell and crawled on. This species is named
as garlic snail, and, like the ruakapangi, is a descendant of representatives
of the native New Zealand fauna. Such an effective chemical weapon was formed
in this species as a response to the appearance of small mammals in the fauna
of the islands.
After meeting the snail, the chicks could not get out of the disgusting taste
in their mouths for some time, and Sharpbeak had to lead the plaintively squeaking
chicks to the water so that they could drink and ease their suffering. The meeting
with the garlic snail was remembered for a long time by the chicks, and in the
future they diligently avoided the snails of this species. Living creatures
can stand up for themselves, and the way of self-protect of a garlic snail is
far from being the most effective. But ruakapangi is a predator, and as the
chicks grow, they will have to learn to face off against their prey, or kill
it in such a way as not to give it the opportunity to defend itself. While they
are young, they have the right to make a mistake, but an adult bird cannot afford
to make a mistake – oftentimes it is tantamount to death.
Over the next few days, ruacapangi chicks have to meet with various species
of animals living in their habitat. While the female protecting them was distracted
and disappeared into the thicket, the chicks were frightened by the castle rabbit.
A beast of the foraging caste crawled out of a hole next to the chicks, and
they were terribly frightened by the sudden appearance of such a large animal
compared to them. But the rabbit itself was no less scared – ruakapangi is one
of the main predators hunting this species. Therefore, seeing the chicks, the
rabbit turned around and disappeared into the tunnel immediately. The chicks,
full of curiosity, decided to see where it had disappeared. After a short search,
they found in the grass the entrance to a tunnel dug by rabbits of the foraging
caste. But both Fidget and Motley did not dare to step into this dark and unfamiliar
world. After standing for a while at the entrance to the tunnel, they turned
around and walked away. They were interested very much in the movement of grass
near the bushes – the chicks had not seen anything like this before. They came
closer and saw a small black and white animal running through the grass. More
precisely, its body was black, and pointed white needles grew on its head and
along its spine. This creature is another descendant of introduced mammalian
species, the tiny shrew-like hedgehog. The animal does not pay attention to
the ruacapangi chicks at all – it has warm blood, and food literally burns in
its stomach. Therefore, while the animal is awake, it is constantly looking
for insects and cannot afford idle curiosity. It is not interested in ruacapangi
chicks, but it becomes an object of observation on their part. Fidget came up
to it quite close, and began to examine the animal.
The shrew-like hedgehog sniffs the ground and grass with its long and mobile
nose. Fidget became interested in what this animal was looking for, and he approached
almost to the very muzzle of the animal. In response, the shrew-like hedgehog
turned its back on him and trotted in the other direction, continuing to sniff
the ground. To catch up with it, Fidget ran ahead and began to examine the animal
almost point-blank. Seeing that the stranger does not want to leave him alone,
the shrew-like hedgehog stopped, raised itself on its outstretched legs and
squeaked with thready voice, baring its teeth. Fidget wouldn’t have approached
it, but his brisk sister did something different. Motley ran up from behind
and strongly pecked the animal’s side. This sudden attack angered the little
predator, and the shrew-like hedgehog began to display the chicks its readiness
for self-protection, despite the fact that each of the chicks surpassed it in
height and weight. The animal squealed shrilly, opening its mouth wide and showing
pointed teeth.
Seeing its teeth, the chicks retreat in fright, and the animal, inspired by
success, continues to frighten them. It bristles pointed needles on its head
and makes sudden rushes towards the ruacapangi chicks, jumping high on outstretched
legs and arching its back like an angry cat. And then it passes to attack and
grabs the Fidget’s fluff with its teeth. The frightened chick recoiled, and
the shrew-like hedgehog hung on his plumage like a bulldog. Fidget is seriously
frightened by the attack of this animal. He ran to his mother, and an angry
shrew-like hedgehog hung on his plumage, squeaking dimly because of the feathers
it holds in its mouth. Motley followed him and began to seek protection from
Harpy. Seeing that chicks have a powerful defender now, the little mammal immediately
released the Fidget’s fluff and tried to sneak away. But a well-aimed peck of
Harpy’s beak killed the shrew-like hedgehog on the spot. Now the chicks can
calmly examine their abuser – a small animal with fluffy fur and pointed needles.
Fidget tried to peck it, but bumped up against the needles and did not try again.
He learned another important lesson for the predator – it is necessary to kill
the prey as quickly as possible so that it cannot injure him. Someday animals
more protected than shrew-like hedgehog will fall his prey, but now even such
small creatures can harm him.
Due to activity of people that disappeared millions of years ago, New Zealand
is no more a relatively safe world of birds. Now the largest animals of the
islands are mammals, and among them there are dangerous species. Many of them
share the habitats with ruacapangis, and even the adult ruacapangi prefers to
avoid some mammals, although these animals are not predators. The ruacapangi
family often finds the signs of the presence of these animals – in some places
the bushes are heavily eaten, and large piles of manure lie among the grass.
The footprints of these animals were imprinted on the soft ground – these are
round marks larger than ruacapangi’s head. Only one mammal of New Zealand could
leave such traces – a huge taurovis, a descendant of a domestic sheep once brought
to the islands, which grew to the size of a large bull. The taurovis herd is
the real embodiment of a force that lacks reason: they are not much smarter
than a sheep, and managed to survive on the islands due to the fact that in
the first millions of years of evolution without a human, they greatly increased
in size and thus became invulnerable.
At some distance from the river, trees and shrubs do not form a continuous cover,
and there are wide paths overgrown with grasses among the woody vegetation.
This is the result of the activity of the taurovis herds. Huge herbivores eat
and trample vegetation, so in places convenient for feeding and going down to
watering place, trees and shrubs are destroyed and wide paths overgrown with
cereals appear. Here a variety of small animals may be met, so the ruacapangi
family stays in these places for a long time. Lizards crawl among the grass,
and small tree frogs live in the bushes – these are descendants of an Australian
species introduced to the islands in the human era. Ruakapangi is able to catch
small animals deftly due to the speed of its reaction. Sharpbeak is particularly
successful in catching tree frogs – he manages to grab them almost in a jump.
And the chicks have not been able to hunt yet, and they have to beg for food
from their parents. The young ruacapangis have grown considerably in recent
days. In the chicks, the juvenile fluff has already begun to come out, and from
under it the first pin feathers appeared. While they look like tubes, the chicks
look very strange, but gradually the feathers begin to unfurl and replace the
fluff. Grown-up chicks require even more food, and parents have to share it
with the chicks regularly, putting yet another small prey item – a lizard, a
frog or an insect – into the invitingly open mouth. However, the chicks themselves
gradually master the basics of hunting skills.
Motley decided to hunt on her own. She hears the voices of her parents, and
keeps in mind which direction to run in order to seek salvation in case of danger.
She already shows quite a lot of independence at an early age, and demands food
from her parents less often than her brother Fidget. She managed to track down
a small gecko among the grass. The lizard is well camouflaged thanks to the
pattern of winding stripes on the sides of its body, and it is very difficult
to notice it while it is motionless. But sometimes a gecko needs to hunt, and
when it moves, it’s easy to spot it. The visual perception of a predator has
one remarkable feature – the predator notices movement well. Therefore, the
lizard, having inadvertently moved, betrayed itself, and Motley attacked it
immediately. One blow with the beak was enough to kill the lizard, and Motley
got the biggest prey in her entire short life. And most importantly, there was
no Fidget nearby, who could take away her prey. Having grabbed the dead gecko,
Motley began to swallow it. This is quite difficult thing to do – she used to
get relatively small pieces of meat that were convenient to swallow, but now
she feels like a one-day-old chick being fed by inexperienced parents. At the
cost of great efforts, Motley managed to swallow a significant part of the prey,
but the gecko’s tail was still sticking out of her beak. After catching her
breath, Motley continued to swallow her prey, and with great difficulty she
still managed to fit the killed lizard in her stomach. She wanted to continue
hunting, but suddenly she heard the Harpy’s anxious voice. The mother called
Motley for a long time and loudly, and even Sharpbeak joined her. The danger
was clearly great, and Motley knew that her parents would not call her in vain.
She did not understand what exactly she needed to be afraid of, and only felt
a faint tremor of the ground under her feet. Cheeping loudly, she rushed to
her parents, around whom a frightened Fidget was already running. When she joined
the family, Harpy led the chicks to the thicket of bushes, and Sharpbeak urged
the chicks, not letting them fall behind or run away to the side.
The trembling of the ground intensified, and soon the birds heard a rumble like
thunder. It was tapped out by dozens of hooves of huge animals – a herd of taurovis
moved to watering place. From their hiding place, the birds watched these creatures.
At the head of the herd an adult male walked, shaking its large head decorated
with short thick horns on the sides. He was distinguished from the mass of his
relatives by a very wide forehead, which formed a kind of “visors” over his
eyes, which gave the beast’s muzzle a harsh expression. He was followed by females,
distinguished by a lighter color, rings of dark fur around the eyes and very
short horns. Taurovis calves, huddled to the sides of the females, had a sorrel
color. The herd of animals went to the river, not looking around and not sniffing
the air, as more cautious herbivores do. As long as taurovises keep each other
in the herd, they simply have no one to fear – they are able to trample any
enemy to death with their wide hooves.
The ruacapangi chicks were frightened very much by the appearance of a herd
of animals that seemed absolutely monstrous ones to them. They pressed themselves
against the ground, trembling from the steps of taurovises, and Harpy had to
simply cover them with her body to calm them down a little. Finally, the animals’
footsteps became quieter, and then they disappeared completely. Sharpbeak got
out of the shelter and looked around, trying to detect danger. However, everything
seems to be calm. Sharpbeak uttered a short call, and Harpy came out of the
bushes to him, followed by Motley and Fidget. The family united, and the birds
continued to search for food.
Ruakapangi is dangerous for the most part of small animals of New Zealand, as
well as for young animals of medium-sized species. However, this bird is not
the only predator of the islands. Ruacapangi’s neighbor is another animal, which
sometimes is frightening even for massive taurovises.
One morning, Sharpbeak brought an unusual prey – not meat, as he had done up
to this point, but a whole rabbit at once. Early in the morning, at sunrise,
he went to the forest and almost immediately got a young forager of castle rabbit.
Now he is ready to teach the chicks the first lesson of how to eat large prey.
Sharpbeak threw the rabbit’s body on the grass, and Motley and Fidget immediately
began to stare at it. They tasted the meat of castle rabbit – this is the most
common prey of ruacapangi. Occasionally they even had to see these animals,
which immediately hid in burrows, as soon as the chicks became interested in
them. Sharpbeak allowed the chicks to peck at the rabbit carcass a little, but
Motley and Fidget were unable to eat anything – they only pulled out a few shreds
of completely inedible wool, and that was it. When they walked away from the
dead rabbit, Sharpbeak showed them how to deal with the prey. He pressed the
carcass to the ground with his toes, grabbed the skin with his beak, and pulled
sharply. The rabbit’s thin skin tore easily, and the insides spilled out onto
the grass. The chicks watched their father closely, not yet understanding the
meaning of his actions. Finally, Sharpbeak tore off a piece of rabbit meat and
froze for a second, holding it in its beak. And then he just swallowed it. Then
Fidget was the first to decide to repeat his movements. He approached the prey,
and after several attempts tore off some meat. Having tasted it, he immediately
understood the meaning of the actions of an adult bird. Swallowing the meat,
he tore off another piece, but at that moment, Motley sneaked in him from behind
and snatched the meat from his beak. With some difficulties, the first “adult”
meal of ruacapangi chicks continued, but none of the birds suspects that circumstances
are already taking a very undesirable turn.
The smell of meat and blood of a dead rabbit attracted an extremely dangerous
guest. A large beast with a spotted skin and a bushy tail was wandering in the
bush, looking for food, and quite accidentally sensed the smell of ruacapangi’s
food. The animal instantly decided to act at impulsively – it often managed
to take prey from weaker animals. After sniffing, the beast determined where
the smell came from, and wandered to its source.
The ruacapangi chicks were still tearing pieces of meat from the rabbit carcass
when Harpy uttered a sharp alarm signal. The chicks stopped eating and looked
in the same direction as their mother. When Harpy began to call the chicks to
her, they felt the fright in her voice, and began to squeak anxiously. A large
spotted animal with a short muzzle, clawed paws and a long fluffy tail appeared
from the bushes. This is probably the only animal that is truly dangerous for
ruacapangi – the marsupial pardus, the largest predator on the islands. Even
adult birds do not always risk fighting with it, and the ruacapangi chick is
an easy prey for this predator. If Sharpbeak and Harpy did not have offspring,
they would simply escape, leaving their prey to the predator. However, chicks
squeaking plaintively at the feet of adult birds represent a reason for active
defense. Sharpbeak uttered a staccato alarm signal, and the chicks hid in the
bushes. A pair of adult birds united to fight back against the predator. Nevertheless,
the marsupial pardus is not interested in ruakapangis – it is much more attracted
to a half-eaten rabbit carcass lying in the grass. This marsupial pardus is
just a young animal that recently left its parents. It is still too young to
have a family of its own, and so far, it wanders through the forest alone. Lonely,
and not yet experienced enough, the young marsupial pardus can hardly feed itself,
so it is forced to feed on random prey or take it away from weaker predators.
The marsupial pardus has not yet reached full strength and maturity, and it
is not going to attack birds with sharp beaks and quick reaction at all. However,
it is trying to impress them with its actions. The marsupial pardus lunges towards
the birds, tears the grass with its claws and growls, showing its sharp front
incisors. In order to enhance the impression, it raises his fur and lifts up
a long fluffy tail. Adult marsupial parduses live in family groups and do not
resort to such displays – they are quite confident in their own abilities, and
ruacapangis would not get into a fight with them. But now the forces of the
animals are about equal, and the ruacapangis are trying to resist a single beast.
The birds scream loudly, supporting each other, and attack the marsupial predator
together. Harpy made a sharp lunge, and almost reached the shoulder of the beast
with its beak, but the marsupial pardus managed to dodge. In response, it hit
the bird with its paw and tore a bunch of feathers from Harpy’s side. She jumped
back, and at the same moment, Sharpbeak managed to hit the beast in the other
shoulder with his beak. His beak sank deep into the predator’s muscles, causing
a deep and painful wound. This attack decided the outcome of the fight – the
marsupial pardus retreated immediately. A small prey is not worth serious wounds
that will make it a bad hunter for a long time, or even for the rest of its
life. Therefore, the marsupial pardus turned around and left, nervously twitching
its tail.
When the predator disappeared into the bushes, the ruakapangi pair did not calm
down for a long time. Sharpbeak snapped his beak threateningly after the predator,
and Harpy supported him with screams. They gradually calmed down only after
some minutes, and after that Harpy in a gentle voice called Restless and Motley,
who sat in the bushes, freezing with fear, throughout the whole duel of birds
with a predatory beast. The bird family is back together, and Harpy can give
herself some time. She carefully touches with her beak the place where the paw
of the marsupial pardus tore out the feathers. The claws of the beast left several
deep scratches on the bird’s skin, although the plumage greatly softened the
blow and saved Harpy from a more severe injury. The wounds will heal soon, and
this injury has not affected Harpy’s hunting abilities in any way. It is very
important if there are two chicks in the care of adult birds. Another important
lesson was learned by the chicks – they have memorized the image of the most
dangerous enemy, and now they will avoid meeting it at every opportunity.
Fidget and Motley turned three weeks old. They have changed a lot compared to
what they were immediately after hatching. The chicks have overgrown with feathers
and have become much more like adult birds in appearance. Only their tails are
still rather short. Motley still differs from Fidget in the color of her plumage:
on her belly, the feathers have white tips that form an intermittent cross-striped
pattern. The same pattern, although less pronounced, is on Harpy’s plumage.
The juvenile fluff on the heads of Fidget and Motley has come off without a
trace, and the chicks now have featherless faces like adult birds. This allows
them to eat the meat of large prey keeping the plumage clean.
The ruakapangi family lives on the South Island of New Zealand, in a subtropical
climatic zone. The end of spring in this area is notable for warm and humid
weather. From time to time it rains, and the chicks are forced to hide from
the rain under the plumage of adult birds. But then drier weather sets in, and
ruacapangi family moves closer to the water.
Traces of human activity associated with the introducing of animals to new habitats
have been preserved millions of years after human disappearance. And the most
notable of them is the abundance of mammals in the fauna of the islands. A watering
hole is a place where many species of local fauna may be seen. A variety of
animals inhabiting New Zealand roams on the banks of the river flowing in the
valley. Some of the most magnificent inhabitants of Neocene New Zealand are
ultradamas – huge deer. These descendants of the fallow deer introduced to the
islands have become one of the largest deer on Earth. The adult ultradama male
is the size of a small horse, but height is not the most impressive feature
of the animal at all. The antlers of an adult male of this species represent
an impressive sight. Only the horns of the fossil Megaloceras deer can compare
with them. The span of the antlers of an adult ultradama male reaches almost
three meters. But in the spring, the antlers of the males are still being formed,
and the animals do not look as majestic as in the autumn, before the beginning
of mating tournaments. In the spring, when it is too early for the mating tournaments,
ultradama males treat each other quite peacefully, and form separate herds.
Because of their antlers, males prefer to stay in areas of a forest stand disturbed
by taurovises, in sparse forests and bush thickets, and even animals that have
lost their antlers remain there. In the bushes, males make their own paths,
avoiding areas where trees begin to grow. In addition, the ultradama feeds on
relatively soft foliage and “trims” the bushes, biting off their tops, preventing
them from growing up and forcing them to branch abundantly.
A herd of males of these huge deer is approaching the watering place. Even if
the males do not have antlers, they can be distinguished from the females by
size and color – the wool of the ultradama males is reddish-brown, and lacks
characteristic white spots. By the beginning of spring, their antlers have already
begun to grow – they are still small, but the shape they will acquire by the
mating season is already guessed. There are individuals of various ages in the
herd of males. A pair of young males will grow only small antlers by autumn,
which lack lateral prongs. These males only left their mothers and joined the
herd of males last winter. It will take several years before their antlers reach
normal development, and the animals will be able to take part in mating tournaments.
An animal a year older than them already has a short mane on its neck, and its
growing antlers have a characteristic “palm”, but lack prongs so far. Several
more males have antlers at various stages of the development of the “palm” and
prongs, and noticeable brown manes grow on their necks. The herd is headed by
a huge mature male with a dark, almost black mane. Its antlers are still small,
but by autumn they will reach a span of over two and a half meters. This male
has lived for more than fifteen years, and knows from experience that predators
most often attack near a watering hole. Therefore, when the deer come to the
river bank, he lingers a little. The giant male sniffs the air, flaring his
nostrils wide, and carefully looks around the neighborhood, hoping to detect
the approach of a predator in advance. The rest of the deer scatter along the
riverbank and crouch down to the water, trying not to touch each other with
their antlers. The adult male did not approach the water until the first of
the deer finish watering and moved away from the river. Only then, he went into
the water and began to drink slowly and with dignity.
The characteristic alarm signal of the ultradama, a staccato squeaky bark, repeated
many times in a row, is well known to almost all large animals of New Zealand.
The senses of these animals are very well developed, and the ultradamas notice
the approach of predators from afar. Adult ruakapangis are also very familiar
with this voice – although they would never dare to attack an adult ultradama
male, these animals often disrupted their hunting, making all the animals around
them wary. But now the ruacapangi family does not hunt, and they are not the
reason for the alarm at all: the ultradama males do not even see these birds.
The young ultradama male was “barking”, looking at several massive animals that
appeared from the bushes. Hearing his signal, the rest of the deer moved away
from the water and gathered on the riverbank. Even an adult experienced male
stopped drinking and looked towards the shore.
A group of massively built animals is walking towards the water. These animals
are very close relatives of the marsupial pardus – they had common ancestors
introduced to the islands by people. They have large flattened heads with short
ears and large eyes, and their bodies are covered with shaggy gray hair with
a black stripe along the animal’s back. These are ursine cuscuses, the largest
marsupial mammals outside of Meganesia. They trudge to the water on their hind
legs, resembling small fur-covered dinosaurs. Near the water, the animals sniff,
closing their sensitive eyes a little bit, drop to all fours and quickly lap
up the water. If the waking time for ultradama began only recently, then ursine
cuscuses are preparing for sleep in the morning. All night they fed on the foliage
and branches of low-growing trees, bending them to the ground with strong front
paws. After watering, the herd will hide among the bushes, where the animals
will not be disturbed by a random predator, and will sleep until the evening.
The ultradamas made sure that ursine cuscuses did not pose a danger to them
– the young male stopped “barking”, several deer continued to drink, and the
adult deer lowered its head into the water, pulled out a bunch of water plants
with a sharp movement, and began slowly chewing it, looking at the large marsupial
beasts.
A cub rides the back of one ursine cuscus female. When its mother came to the
water, it quickly got down to the ground and began drinking also. This cub will
soon pass to independent life, but for now, it feels a connection with its mother
and always stays around her. In case of alarm, it will definitely seek protection
from his mother.
Suddenly, the alarming “barking” of the ultradama resounded again. This time
it was uttered not by a young timid male, but by an older animal that is no
longer afraid of its herbivorous neighbors. This alarm is no longer illusory,
and the ultradamas are beginning to worry. Another male begins to “bark”, then
several more animals join it. Slow-thinking ursine cuscuses also realized that
the danger is quite real. They stopped drinking, and the cub immediately climbed
onto the female’s back and grabbed her fur with its claws. The ultradamas moved
away from the water and looked cautiously towards the bushes, and the ursine
cuscuses did not figure out where the danger would come from. They reared on
their hind legs and prepared to fight back against any enemy that appeared nearby.
The powerful front paws of the ursine cuscus are armed with sharp claws, with
which the animal can inflict terrible wounds on the enemy.
Away from the ultradama herd and a group of ursine cuscuses, a family of ruakapangis
appeared on the riverbank – Sharpbeak, Harpy and two of their chicks. They are
not going to hunt and just drink, not paying attention to the beasts. Sharpbeak
drinks first – he goes to the water and takes some sips, raising his head high.
Harpy drinks after him, and then the chicks come to the water. The birds do
not suspect that they, born hunters, have become the object of hunting themselves
at this moment.
On the surface of the water, long leaves of eel grass trail downstream. This
plant was introduced to the islands by people millions of years ago, and in
the Neocene, when the world free of the burden of humankind changed, this plant
became a part of the new ecosystems of New Zealand. The foliage of eel grass
is very tender and watery, and the adult ultradama male willingly ate quite
a lot of this plant. He did not cause much damage to the thickets – within a
week, eel grass is quite capable of growing as thickly as before on the vacated
part of the bottom. But a large animal disturbed one of the inhabitants of the
thicket.
The movements of the legs of the ultradama male startled the animal that lived
among the underwater vegetation. Having torn out several bunches of eel grass,
the large beast deprived this creature of shelter and forced it to look for
a new place of residence. The underwater inhabitant, covered with soft bumpy
skin, lay in the shade of leaves fluttering in the current and patiently waited
until the fish or crayfish got close enough to snap it. However, this time,
instead of hunting, it had to escape from the feet of a huge beast, which raised
clouds of sand and silt from the bottom. When one of the deer’s legs got to
the bottom not far from this creature, and the beast’s lips pulled out a bunch
of plants from the bottom, the animal decided to swim away. It lazily waved
its tail and swam, pressing very short paws to its sides. This animal is a representative
of amphibians, which is named as neohanasaki. Its evolutionary history is also
very dramatic. Like the mammals of New Zealand, this animal is a descendant
of the invader, the human-introduced Australian tree frog Litoria caerulea.
Millions of years ago, looking at the ancestors of this monster, it was hard
to imagine who they would become in Neocene. Neohanasaki belongs to the group
of neotenic anurans, and in fact represents an “adult tadpole” whose ancestors
lost the ability to turn into an adult frog millions of years ago. This creature,
about one and a half meters long, is the largest species of New Zealand amphibians
and is a voracious predator similar to the wels catfish. The flat head of neohanasaki
has a wide mouth, not far from the corners of which tiny eyes are located in
small depressions. This animal does not like to swim for a long time – after
swimming a few meters away from the ultradama male, who disturbed it, neohanasaki
sank back to the bottom and dug into the ground with several movements. Its
wrinkled skin perfectly masks the animal, making it look like a piece of a sunken
tree trunk. Skin of neohanasaki is rich in receptor cells. This monstrous “tadpole”
has very poor eyesight, but it is compensated by numerous chemoreceptors that
catch all kinds of odors, as well as by dense network of lateral line channels
that help the animal distinguish between the movement of water and waves that
are formed when various objects move in the water. Strong waves spread from
the heads of large animals drinking water – they are not attractive to neohanasaki.
The animal evaluates their strength, and the instinct of self-preservation suppresses
the animal’s feeding behavior. On the contrary, waves radiating from small moving
objects attract its attention very much.
Neohanasaki felt two large creatures appear near the shore at first, one after
the other, and after them two small ones appeared at once. The primitive brain
of the huge “tadpole” assessed the situation, and the animal began to creep
up to them cautiously, stepping over the bottom with its small legs. On land,
this creature would be completely helpless – small legs are simply unable to
support its weight. But in the water it weighs almost nothing, and moves on
its legs with the ease of a dancer. This predator often preys on the chicks
of ducks and other waterfowl. Now the object of its hunt is a terrestrial creature
that is on the shore. The flattened body shape allows the animal to sneak up
on its prey almost at point-blank range. The predator noticed ruacapangi chicks
drinking water, crept up to them, and then abruptly waved its tail and rushed
at the prey.
A huge body covered with slimy skin jumped out of the water suddenly, and adult
birds did not have time to react to its appearance. The monstrous “tadpole”
snapped Motley by the head and jerked her under the water. The wave raised by
the rush of the neohanasaki literally threw Fidget to the feet of his parents,
and the predator, seizing the prey, turned around, pushed off from the shore
with a wide tail and disappeared under the water, leaving behind itself only
clouds of mud spreading in the water. A bubble of air floated to the surface
– the last thing left of Motley. The attack happened so quickly that the parents
could not do anything to save their chick. Under the water, neohanasaki turned
Motley’s body head first and began to swallow it whole. A significant part of
the prey entered its stomach without problems, but the long legs of the prey
stuck out of the predator’s mouth for a while. Gradually, making efforts, neohanasaki
managed to put the whole prey into the stomach. Now this animal with a slow
metabolism can not eat for about three weeks.
Life has taught Fidget one of its most terrible lessons. Now Fidget will be
very careful near the water while it is too small, and in the future it will
also peer into the water carefully before starting to drink. But there is another
side to this tragedy: the death of Motley increased his own chances of survival.
Now all the food and all the parental care will go to him alone, and Fidget
will have a good opportunity to live up to independence.
The seasons gradually change each other even in the warm climate of Neocene.
Summer has passed, and autumn has followed it – a time of abundance, when many
young and fat castle rabbits appear in the forest. When it got colder, neohanasakis,
these huge “tadpoles”, moderated their appetite and began to gather in deep
pools. Snow in Neocene New Zealand is found only in the mountains, and the rivers
in the valleys do not freeze. Therefore, neohanasakis remain active, but in
cold water their movements become sluggish, appetite is reduced in great degree,
and they spend most of the time in immobility.
It gets noticeably colder in late autumn. Ruacapangi’s family ties have been
preserved for a very long time, and Fidget still lives and hunts with his parents.
He learned to get castle rabbits almost as deftly as his father, and he had
to participate in a joint hunt for large prey. The ruacapangi family does not
starve – thanks to the coordinated actions of the birds, they manage to get
grown up ultradama fawns, as well as slow, but dangerous ursine cuscuses. The
two most dangerous winter enemies of all animals are hunger and cold. Of course,
thanks to the ocean, the climate in New Zealand is not as harsh as in Eurasia,
but all the same it gets noticeably colder at night, and sometimes frost appears
on the grass, quickly melting in the morning. A family of birds gets together
at night and they warm each other. During the time that has passed since the
death of Motley, Fidget has grown very much, and now he is only slightly inferior
in height to his mother. Perhaps if Motley had been alive, he would not have
been able to develop so successfully, and he might even have died without getting
enough food. But by the fall he had reached quite a suitable size to start an
independent life. However, he does not hunt too well yet and prefers to forage
with his parents. Hunting together, ruakapangis have a better chance of getting
prey.
Other animals also feel the changes in nature. In the morning, when the fog
falls thickly on the bushes, in the distance the loud roar of the ultradama
males is heared. In late autumn, the antlers of the males are fully formed,
ossify, the dead “velvet” this time peels off from them, and the ultradama males
become very aggressive. Meeting with such a male can be very dangerous, so the
ruacapangi family stays away from them.
Ruacapangi family sleeps together – it’s much warmer this way. Moreover, Fidget,
despite its size, still manages to use children’s privileges – he climbs between
his parents, and spends the night in warmth. In the morning, dew settles on
the leaves of shrubs where birds hide, and drips on the plumage of adult birds,
soaking it to the skin. The touch of cold dew is unpleasant, and Sharpbeak and
Harpy wake up from time to time and shake to free themselves of dew drops. Then
they wake up at all and begin to stretch the leg muscles that have become numb
after the night. Birds must be in good physical shape to hunt successfully.
It is especially important in the cold season – in autumn, many small animals
like insects and lizards hid in burrows, and random prey is not enough to feed.
The rustle of the bushes warns the birds that someone is approaching them. However,
they do not have to look closely to determine that a huge male ultradama has
come to them. An animal of enormous stature strides majestically through the
bushes, and its head, crowned with antlers more than a meter long, stands out
against the background of the morning sky. Although the ultradama is among the
herbivores, this beast now poses a real danger to ruacapangis. In autumn, during
the mating season, hormones make males easily excitable and aggressive. Moreover,
this giant weighs three times more than the whole ruacapangi family. He is an
adult, and his antlers are fully formed. From the base of the ultradama’s antlers,
two straight pointed prongs branch off, directed forward. With their help, males
fight with each other, and when defending against a predator, antlers serve
as a terrible weapon – with their help, ultradama male is able to pierce through
a marsupial pardus if this predator turns out to be too careless.
Ruacapangi family retreats, trying to keep a sufficient distance, but the beast
does not lag behind. Under the influence of sexual hormones, the ultradam male
loses caution and tries to hit any animal that gets in his way with its antlers,
taking it for a rival. It is very aggressive, and barks in a characteristic
manner, chasing ruakapangis. The birds do not try to defend themselves and prefer
to flee – they squeeze into the thickest bush, where a huge deer will not fit.
The birds hear the animal trying to chase them, pushing the bushes apart with
its chest. But soon the chase stops. The ultradama male gets out of the thickets
and walks around their edge for a while, shaking its head and barking. But it
does not see the hidden birds, and its attention gradually weakens. After walking
along the edge of the bush, the animal moves away, majestically shaking its
antlers.
When the silhouette of the ultradama male blurred in the morning haze, the bushes
stirred, and Harpy got out of them. She was followed by Fidget, who was urged
on by Sharpbeak. The birds looked around for a while, but then, finding no signs
of danger, they went into the forest.
In late autumn, thickets of shrubs are a very restless place. The ultradama
females, ready for mating, leave the forest and go to the large clearings where
the mating tournaments of males take place.
Winter in New Zealand is not cold even in the very south of the South Island.
Rivers do not freeze, and only on the coldest days in the morning, a thin crust
of ice appears on puddles. The trees only partially shed their foliage, and
some of them are evergreen at all. It is warmer in the depths of the forest
than in the open or in the mountains, and the ruakapangis move to the forest
for the winter. During the short winter days, Fidget learned to hunt on his
own. He left his parents for the whole day, and learned to get food independently
by ambushing the castle rabbits. Often Fidget was looking for prey right next
to their building – a huge hill, pitted with holes and reinforced with branches
and twigs cemented in clay. Fidget was interested in looking into the holes
leading inside the building. Sometimes crickets could be heard trilling from
there in the middle of winter, and on the ground next to the rabbit “fortress”
he noticed insects frozen from the cold – the inhabitants of the rabbit building,
who accidentally appeared on the ground surface. However, a close acquaintance
with the rabbits’ building was often interrupted by these animals. If Fidget
stayed for a long time near the rabbit “fortress”, rabbits came out of the holes,
which were not like foragers he was used to preying. They were very large animals
with striped black and white heads – rabbits of the “soldier” caste. Uniting
in small groups, they threatened Fidget, baring their sharp incisors, and even
attacked him. After several bites, Fidget began to avoid encounters with these
animals, and preferred to hunt away from the “fortress”, lying in wait for solitary
foragers in the bushes. So far, he had not thought of attacking a larger prey.
The seasons follow one another, and winter gradually gives way to spring. The
days are getting longer, the sun is shining brighter, and this stimulates changes
in the organisms of birds. Sharpbeak is beginning to behave very strangely more
and more often: he runs after Harpy and “dances” around her, whirling awkwardly
and stretching his head up. However, as soon as Fidget is near, the dancing
of Sharpbeak stops, and he begins to behave as if nothing had happened. But
changes are inevitable, and they are coming closer every day.
After a successful hunt, the ruacapangi family gathered near the prey – the
birds managed to kill a young ursine cuscus. Sharpbeak and Fidget separated
this animal from the herd, and drove towards Harpy hiding in the bushes. Ursine
cuscuses are not very intelligent, and the beast did not immediately realize
that it was trapped. Only when it was surrounded by three birds at once, it
reared on its hind legs and prepared to give the last fight. However, ruakapangis
attacked it with lightning rushes, not giving the animal an opportunity to use
hooked claws of its front paws. Animals with more complex behavior would be
able to repel the attack of the ruacapangi by acting together, but ursine cuscuses
prefer to flee, leaving a relative in trouble one-on-one with predators.
The carcass of ursine cuscus is a good prey for ruacapangis. The family can
feed on it for several days, as long as the meat remains edible. After making
sure that the animal wounded by sharp beaks has died, the birds begin to eat
their prey. With an effort, Sharpbeak tears the strong skin on the side of the
animal, and the whole family begins to peck at warm fresh meat. During the meal,
adult birds gradually push Fidget away from the prey and eat delicious liver
and soft insides, not sharing them with him. Fidget is not going to give up
his privileged position so easily and demands attention to himself – he crouches
slightly, imitating a chick begging for prey, and tries to snatch a piece of
meat from his father’s beak. Previously, it passed without consequences, but
this time Sharpbeak unexpectedly displays aggression. He straightens up, clicks
his beak, and begins to push Fidget roughly away from the prey. In response,
Fidget takes the pose of a chick begging for food again. However, this time
Harpy joins Sharpbeak, and the adult birds push Fidget together away from their
common prey. When Fidget tried to get around them to tear a piece of meat from
the carcass, Sharpbeak snatched its plumage. Fidget screamed loudly, but Sharpbeak
did not let him go. He only tightened his snatch on his own son’s feathers,
and when Fidget jerked sharply, a bunch of his feathers remained in Sharpbeak’s
beak. Instead of eating, young Fidget got the first thrashing in his life.
Fidget does not understand the changed relation towards him. He managed to beg
for meat earlier, and his parents fed him. Times have changed though – at that
time he was small and required parental attention. Obeying instinct, his parents
fed him, and if necessary, they could stand up for him, even if the enemy surpassed
them in strength. Now Fidget is almost as tall as the female, although it weighs
less than her. The parental instinct of Sharpbeak and Harpy has gradually faded
away, and they are preparing for a new nesting. The increase in daylight hours
caused hormonal changes in their bodies, and the strange behavior of Sharpbeak
is a separate element of the mating dance of ruacapangi. Before nesting, the
pair of birds becomes more aggressive towards their relatives, and the birds
see not a chick, but a competitor in their own offspring. This fact explains
their behavior towards Fidget.
While a couple of adult birds are eating prey, Fidget is forced to stay away.
When he gets too close to the feasting parents, they turn to him with their
beaks and emit warning cries that force Fidget to retreat. Sharpbeak and Harpy
tear off pieces of meat greedily and swallow them hurriedly – in the presence
of Fidget, they behave as if he is going to take their prey from them. However,
they can’t keep eating indefinitely, and the carcass of the ursine cuscus is
too big for a ruacapangi couple to eat it all in one sitting. Having had enough,
Sharp-Beak and Harpy move away from the carcass and lie down on the ground to
have a rest. Then Fidget cautiously approaches the remains of the prey, gingerly
looking at the birds, which treated him not so aggressively and considered him
as a kin this morning. After the feeding of two adult ruacapangis, there are
not very many soft parts left on the carcass, and Fidget gets only scraps of
meat. The beak of ruacapangi is well adapted to tearing soft meat, but when
all the soft parts are eaten and only the meat on the ribs remains, the bird
can hardly feed on the remains of meat. Fidget begins to tear up the remains
of meat with his beak, holding the carcass with his toes. When he accidentally
approaches the resting Sharpbeak and Harpy, the birds greet him with a warning
signal, ruffle the feathers on their heads and necks, and open their beaks wide.
And then Sharpbeak stands up and simply drives Fidget away from the remnants
of prey.
Parting with his parents is completely routine – when evening came, young Fidget
simply did not spend the night with them, but independently chose a place in
the bush where he settled down for the night. His connection with his parents
weakened, but did not disappear completely: he settled down for the night not
far from them.
Waking up the next morning, Fidget began to look for his usual surroundings
– Sharpbeak and Harpy. They have always been there for as long as Fidget has
lived in the world. But he managed to find only a hole in the soft ground among
the bushes, in which some cross-striped feathers lay. Parents are gone – now
they have their own life, and Fidget is not a part of it now. The young male
is not used to living on his own yet – he looks around, searching for the images
familiar from hatching, but does not find them. Until that day, his parents
were in his eyes a familiar part of the world around him, and their proximity
promised safety and satiety, and later success in hunting. Now everything has
changed – independent life has begun, and many phenomena have opened up to the
young ruacapangi male from the other side. What was available previously due
to the experience and skills of parents, suddenly became unattainable. Now Fidget
must hunt and take care of his own safety himself. During this period of life,
many young birds die from hunger and disease, as well as from unsuccessful herbivorous
animals hunting or in the clutches of predators. Often the marsupial pardus
becomes a hunter of young ruakapangis. This predator is merciless, and a bird
weakened by hunger or disease becomes its easy prey.
Ursine cuscus, ultradama and taurovis are large herbivore species, and hunting
them alone is very dangerous. Even the marsupial pardus does not always risk
fighting them one-on-one, and the fragile mobile ruakapangi can simply be trampled,
pierced by horns or torn by the claws of these animals. Fidget looks around
the neighborhood, and notices an ultradama herd in the distance. These are females
with fawns, but their herd is too large to try to attack them. Protecting their
fawns, the ultradamas can strike with strong hooves, and Fidget is rightly afraid
to hunt them. Nevertheless, he is ready for an independent life – before his
parents drove him away, he practiced hunting skills for several winter months,
preying small animals. Now this skill is of vital importance for him.
Fidget knows that there are several places where castle rabbits, mammals leading
a social lifestyle, live at the territory of the vast river valley. The shelter
of these rabbits is a large, solid building with many entrances, tunnels and
living chambers. To destroy or at least to excavate it is a task beyond even
a large predator. When predators appear, large rabbits of the “soldier” caste
come out of the tunnels, boldly attacking the enemy. Fidget knows from experience
that it is better not to mess with them. Alone, any rabbit is cowardly, but
together the “soldiers” of this species are able to drive away from the colony
even an adult ruakapangi. Therefore, Fidget prefers to hunt in a more familiar
way: in the forest, in the vicinity of the shelter of these rabbits, he tracks
down foraging rabbits gathering food for the entire colony. Tunnels stretch
underground for many tens of meters from the “fortress”, through which rabbits
get to the feeding areas, and numerous exits lead to the ground surface.
Fidget knows that foraging rabbits do not move far from the exits. If it is
necessary to get to a site with more lush vegetation, then they are ready to
dig a new tunnel, abandoning the old one, rather than lope some meters on the
ground surface. Therefore, Fidget chooses a place for an ambush near the exit
from the tunnel. He chose a good place – one of the exits leads to dense bushes,
where it is easy to hide. It was dug quite recently – wet ground is noticeable
near the edge of the hole. It is quite possible that the first foragers have
just started using it, and do not yet know that a predator is waiting for them
in an ambush.
Fidget lay in ambush, choosing a place among the bushes where he can clearly
see the exit of the tunnel. He knows how to remain motionless, putting all his
strength into one exact rush. In addition, its plumage does not stand out against
the background of vegetation, and neither the prey nor any of the forest dwellers
who can raise the alarm and scare the prey will notice it.
He didn’t have to wait long – soon a slight rustle heared, and the head of castle
rabbit appeared on the ground surface. This is a large forager – it has distinct
white stripes on its cheeks. Perhaps it could become a “soldier” of the colony
– the bright color of the stripes indicates a high level of testosterone in
its blood. But for now it is leaving the colony for food. And it is completely
unaware of ruacapangi’s presence.
Fidget easily killed it – a peck of his beak pierced the rabbit’s head on the
spot. Having grabbed the prey with his beak, Fidget dragged it to the shelter,
where he began to tear it apart and eat meat. He can peck only the softest parts
of the carcass – the insides, the meat on the legs and some meat in the dorsal
part of the prey. The head and ribs also contain a lot of edible parts, but
ruakapangi is not able to gnaw bones, and leaves these parts of the prey uneaten.
While Fidget was eating prey, a bird was watching him from the branches. As
long as the ruacapangi male was near the prey, it was useless to approach him
– in such a situation he could well attack, as he would do with any competitor.
But the bird had a completely different goal – it needed more than just this
half-eaten rabbit. When Fidget moved away from the remains of the rabbit carcass,
a very large bird with a brown head and striped green wings flew down from the
tree. Fidget had seen such birds before, but only from afar: if they approached
him, his parents drove them away. Now he has the opportunity to look upon such
a bird better. The bird also looked at Fidget, and then went to the remains
of his prey with a confident gait. The rabbit bones crunched in the bird’s black
beak, and then it took a piece of the carcass with its paw and brought it to
its mouth. It is a parrot, but of a special kind – the eagle kea, the largest
species of New Zealand parrots. Like ruakapangi, it is a descendant of the species
of indigenous New Zealand fauna. Biting off pieces from the remains of the rabbit,
it looks at Fidget with a watchful eye, being ready to move away to a safe distance
at any moment. This parrot is looking for allies in the search for prey, and
now its choice was Fidget. Eagle kea is not alone – another bird is waiting
for it in the branches. A couple of these parrots will not leave Fidget for
a long time. For now, Fidget does not understand what these birds want from
him – he has never hunted in cooperation with them before, and his parents did
not do so. But eagle keas often conclude such an unspoken alliance with larger
predators – parrots eat the remains of their “patron”’s prey, and help it in
search for prey. Some of these birds follow the family groups of marsupial parduses
and eat the remains of their prey, although this is quite dangerous – marsupial
pardus can catch and eat such a parrot.
Over the course of several weeks, the relationship between eagle keas and Fidget
gradually strengthens. For the first few days, Fidget perceived his new companions
only as freeloaders picking up the remnants of prey. But the parrots did not
claim the best parts of the prey that ruakapangi usually eats, and Fidget treated
them very indifferently. Every day they appeared next to him in the morning
and flew away in the evening, or after a successful hunt, having got their share
of the prey. Gradually, Fidget began to understand the connection between the
parrots accompanying him and the luck in hunting. Parrots have more opportunities
to search for prey – they fly high and have a wider view. But they are much
weaker than ruacapangi, and count on joint success in hunting. A pair of eagle
keas actively helps Fidget to look for prey. When flying, parrots find suitable
prey and attract the attention of the ruacapangi male, landing next to him and
indicating the location of the prey with their movements.
Fidget is looking for prey in the bushes, but to no avail. On the ground, he
sees piles of manure and the prints of huge hooves – a herd of taurovises passed
through the bushes shortly before him. These animals are too large, and Fidget
does not try to chase them. But suddenly an eagle kea lands next to him – it
is one bird from the pair that accompanies him for the last weeks. Fidget hadn’t
seen these birds since morning, but he didn’t attach any importance to it. However,
parrots at this time inspected the territory from the air, looking for suitable
prey. The bird glances back at Fidget, looks at him for some seconds, and takes
some steps. Then the parrot flies up, perches on the bush and looks around again.
Its behavior shows that it has found something suitable for hunting. The parrot
waits until Fidget comes closer, then takes off and flies a little more. Fidget
follows him running, comes out of the bush and looks in the direction where
the eagle kea is moving. The parrot did not attract his attention in vain –
there is a herd of small animals grazing on the mountain slope.
Large taurovis prefers to live on flat terrain. Herds of these animals are common
in river valleys, and are often found in wetlands. On the contrary, in the mountains,
on steep slopes, where it is not only difficult for a large taurovis to move,
but also dangerous, its close relative lives – orovis, the another descendant
of a feral sheep. These animals graze in herd among the bushes on the mountain
slope. Orovis’ hind legs are longer and stronger than the front ones, and it
is convenient for animals to graze on a mountain slope. An orovis’ head has
an unusual shape – males of this species have thick frontal bones, and small
horns stick out backwards and serve only for display. The brain of orovis is
small, and a massive bony “helmet” protects it when animals establish the hirerarchy.
The jaws of the beast are quite narrow – with their help, orovis can bite the
aboveground part of plants quite low, thrusting its head into the cracks between
the stones. The orovis males live in the same herd then the females, and the
animals often remind their relatives of their place in the hierarchy by displaying
horns to each other. To do this, the beast lowers its head, and the horns rise
up, showing the tips. If the opponent does not retreat, the threat turns into
an attack – orovis pushes off with strong hind legs, and strikes the opponent
with its head. While the herd is peacefully grazing, two males are busy with
establishing their hierarchy: they thud their skulls over and over again. Males
are very passionate about the duel, and at this moment, they notice almost nothing
but each other. However, while the herd grazes quietly, they can engage in establishing
a hierarchy. Females lack such bony “helmets”, and they are less aggressive.
Several calves born recently are running alongside them, and some young animals
that have not reached full physical development are kept on the edge of the
herd.
Fidget takes view of the herd, assessing the success of the attack, and the
parrot perches on a tree behind him and falls silent. A second bird appears
after it. The parrots know that their part of the hunt is almost done, and now
they are waiting for the beginning of Fidget’s hunt. The young ruacapangi male
moves around the herd, hiding in the bushes. He goes around the slope on which
the orovises graze, and comes to the herd not from below, but from the side.
It’s easier to run this way than up the slope, but the bird comes out on the
slope quite far from the herd. Fidget is separated from the orovises by a long
distance – the bird must overcome about a hundred meters almost in full view
of its prey before reaching a good shelter – a large stone behind which it is
possible to hide before the attack. But it must be done so to get an opportunity
to attack the herd with an exact rush and get a prey. Fidget waits until the
animals return to grazing, and then begins the most difficult part of the hunt.
He cautiously creeps up to the orovises, moving on half-bent legs, and crouching
to the ground at the first sign of animal anxiety. When one of the males raised
his head and looked around, Fidget had to crouch down and hide behind a grass
hummock. The animal didn’t seem to notice anything – the male started grazing
again. Fidget took advantage of this moment, and moved some more meters forward.
A pebble popped out from under his foot, which rolled down the slope and clicked
loudly on another stone. Hearing this sound, the orovises became agitated –
several animals stopped feeding and began to look around anxiously. Fidget had
to hide almost in plain sight again. The bird hid in a small pothole near a
stone, and lay down on the ground, stretching its neck. The dim plumage serves
as an excellent camouflage, and the beasts do not notice Fidget. Finding no
danger, the animals began to graze again, and Fidget was able to continue sneaking
up. He moved some meters to a stone lying very close to the herd, and hid behind
it. Then, choosing a proper moment, he jumped out of his hiding place, and bursted
into orovis herd. The animals rushed in various directions, fleeing from a predator
that suddenly appeared. Strong adult animals, fleeing for their lives, ran up
the slope – it is more difficult so for a predator to chase them, and in the
skill of jumping on mountain slopes, orovis has no equal. With the sharp edges
of their hooves, they cling to the roughness of the stones and easily climb
steep ledges. Some animals just jumped on the big stones and watch the Fidget’s
hunting from there. In such places, they feel completely safe – ruakapangi does
not know how to climb rocks as deftly, and even a marsupial pardus does not
always dare to chase orovis in the rocks, even if it sees the prey. Young animals
are less cautious: in a panic they scatter in various directions, and one animal
runs down the slope. It separates from the common herd, and Fidget immediately
switched to the chase of this particular individual. Orovis rushed around, trying
to reach a high stone on which to escape from ruacapangi, but Fidget received
unexpected help from his winged companions. An eagle kea appeared above the
pursued orovis. The bird clawed at orovis’ fur, and the beast jerked aside in
fright. A predatory parrot cut off orovis’ path to the rocks, and forced it
to flee to the valley, where it actually has no opportunity to escape from chasing.
Often, success in hunting completely depends not on the skills of hunters, but
on a combination of circumstances. A blind chance crossed out all the chances
of escape of orovis – at full tilt, the beast got its foot into a hole dug among
the grass. It immediately broke its leg and rolled down the slope, having lost
its balance. Fidget saw that the prey could not escape, and immediately stopped
the chase. He does not repeat orovis’ mistakes, and walks down the slope more
carefully. At his approach, orovis jumped to its feet and tried to run away,
but the acute pain in its broken leg did not allow it to take even one step
– it immediately stumbled and fell. Then, the next second, the figure of ruacapangi
rose above him. Fidget delivered one precise peck to the beast’s neck, to the
base of the skull, and the young orovis was instantly killed. Seeing that the
hunt was over, a pair of eagle kea approached Fidget.
Several times, Fidget has already faced the fact that another predator, which
was watching his hunt and appeared at the right time, was taking his prey away
from him. Therefore, the first thing he does is hide the prey: he drags the
carcass of orovis into the bushes. It is unlikely that anyone will be able to
accidentally notice Fidget here, and he has more opportunities to eat quietly.
Fidget easily tore the skin of orovis with his beak and began to eat. He immediately
pecked out the liver and soft insides, and then began to eat meat on the legs
of the carcass. Eagle keas wait their turn patiently – if they approach too
early, Fidget may attack them, believing that they are trying to take away his
prey. While the birds keep their distance, Fidget feeds without paying attention
to them. Parrots have hunted with ruakapangi many times, and they know that
they will definitely get a part of the prey. But Fidget tries to eat for the
future, and swallows as much meat as possible. It is unknown when he will be
able to hunt as successfully again. Having eaten to the limit, Fidget moved
away from the remains of the prey, and this was the signal for the eagle keas
– the parrots approached the prey, and their powerful beaks began to crush the
bones of orovis. With their sharp beaks, the eagle keas dexterously cut the
meat between the ribs of the prey, and tore the skin on the legs and back of
the orovis carcass. Where the ruacapangi’s beak is not able to tear the meat
from the bones, parrots find a lot of edible matter. Finally, one of the birds
crushes the side of the head of the orovis, and the birds eat out the brain
of the carcass. After eating, the birds take off, and settle down for the night
near Fidget. Fidget himself doesn’t want to go anywhere anymore. He is full
and becomes very slow and lazy. Having found a convenient place to sleep, Fidget
gets into a bush and falls asleep.
The carcass of the orovis is quite large, and even after feeding of Fidget and
eagle keas, there are enough edible parts left on it. Some of it might have
remained even the next day, but there are always lots of animals who want to
eat someone else’s prey, and they are unlikely to leave behind at least some
edible matter. After dark, there is some excitement around the carcass. At first,
a rustle was heard in the grass, and a gray muzzle appeared among the stems.
This creature might look like some kind of rodent, but when it sniffs, slightly
opening its mouth, instead of the characteristic flat incisors in its jaws,
pointed teeth are visible. A corneous shield grows on top of the animal’s head,
and the ears barely stick out of the wool. The eyes of this animal are very
tiny and almost invisible among the fur. It sees almost nothing, because it
spends most of its time in tunnels that it digs in the soil. This is a taranga
– a burrowing predator, a descendant of the stoat introduced by people. This
animal behaves very carefully on the ground surface and constantly sniffs –
the sense of smell is the most important source of information for this animal.
Guided by the smell, the blind denizen of the burrows got out of the grass.
In fact, it is another participant in the Fidget’s successful hunting and it
is entitled to a legitimate share of the prey. Escaping from Fidget, orovis
got its foot into this beast’s hole. If it had not been for this accident, the
result of ruacapangi’s hunt would be unclear.
In the foothills and mountain forests, burrows of taranga stretch for many tens
of meters shallow from the ground surface, like the burrows of moles in Eurasia
and North America in the human era. The spread of taranga in isolated habitats
is greatly facilitated by one interesting feature of this animal, common to
many invertebrates, but completely unique to mammals. Taranga is an animal capable
of parthenogenesis. Any unfertilized female in this species periodically gives
birth to cubs, and all of them are also females. Therefore, it is enough for
one female of this animal to get into places convenient for life in order to
form a breeding population of these animals.
By the smell, the taranga easily found the Fidget’s prey and clung to the remains
of the meat. Taranga is very cautious – it rarely appears on the ground surface,
because it is adapted to a burrowing lifestyle. It usually feeds on small animals
that fall into its tunnel system, and meat is rather an accidental and pleasant
addition to the main diet. Like all small warm-blooded animals, the taranga
has a very good appetite, and should eat food in an amount of at least half
of its own weight overnight. Therefore, it does not miss the opportunity to
profit from a free treat, even if she has to leave safe burrows and to go out
into an alien habitat for itself – to the ground surface – for this purpose.
With its sharp teeth, the taranga easily bites off the meat from the bones of
the killed orovis, and its small muzzle allows it to penetrate into places where
the beaks of ruacapangi and eagle kea could not tear off the meat. But the taranga
should always be on guard – it is very vulnerable on the ground surface, and
the remnants of the prey of large predators attract various inhabitants of forests
and shrubs, and some of them can also eat the taranga.
Another carrion lover smelled the remains of orovis. It sniffed the air, determined
the direction from which the smell was coming, growled hollowly, and went in
search of the remnants of Fidget’s prey. The large eyes of the animal flashed
yellow in the dark – this animal sees perfectly at night. Some of its congeners
also felt an attractive smell. They abandoned their usual food, the leaves of
the shrub, and moved in search of a more attractive treat. These animals are
ursine cuscuses. During the day they prefer not to face ruakapangi, but at night
they become bolder and more aggressive, and can encroach on the remains of the
prey of daytime predators. They usually feed on foliage, but if possible, they
willingly eat carrion. The animals are adult and large enough not to be afraid
of anyone, and there are several of them, which gives them confidence. Hearing
their heavy footsteps, taranga rushed to the hole and disappeared into it, and
Fidget woke up and looked around. His eyesight is well adapted for daytime hunting,
but at night he sees poorly, and so far prefers not to do anything.
The rustle of branches is approaching, and ursine cuscuses come out of the bush
one by one. They sniff and quickly find the remains of the Fidget’s prey. After
the feast of ruacapangi and eagle keas, there is almost no meat left on the
one side of the carcass, but ursine cuscuses easily turn the carcass over and
find a lot more edible matter on it. The disturbed Fidget woke up and tried
to drive away one of the uninvited guests who came too close to him. But the
massive beast reared up and made several sharp movements with its clawed front
paws. It is a terrible warning, and Fidget retreats. In any case, Fidget alone
would not be able to defeat ursine cuscus. Therefore, night guests eat the prey
of ruacapangi without encountering resistance from the rightful owner. Within
two hours, they managed to eat almost everything possible, and by morning, only
separate bones and gnawed vertebrae remained from the Fidget’s prey.
After a successful hunt, Fidget began to be haunted by failures. Maybe the orovises
became more cautious after his attack, or the eagle keas unwittingly betray
the approach of a predator – it’s hard to say the reason for of the failures
in ruacapangi’s hunting, but for several days in a row Fidget failed to catch
anything larger than a lizard. He is very hungry, and must spend a lot of effort
to get food literally by the crumbs. Random prey like lizards and small animals
is good for a chick, but not for an adult bird – he needs large prey. Fidget
tries to hunt in various places, but sometimes he has to save his life – the
bird often sees footprints of marsupial parduses on the ground, and occasionally
these predators arranged a chase for Fidget, and only his own speed and agility
saved him. Another time he tried to get an ultradama fawn, but the females noticed
him and simply drove him away from the offspring. Fidget did not want to experience
the blows of the sharp hooves of these animals, and he showed prudent caution.
However, hunger is making itself felt more and more. Fidget’s stomach is cramped
with hunger, and the bird comes to the riverbank to drink – the water will somehow
weaken the feeling of hunger. Fidget chooses a secluded place where he will
not be noticed by large herbivores or predators, and descends cautiously to
the water. He carefully made his way through the thickets of water plants and
began to drink, raising his head after each sip.
When the pain in his stomach subsided a little, Fidget looked into the water.
His attention was attracted by a small water beetle swimming fussily near a
thicket of underwater plants. Fidget watched it for some minutes, hoping to
peck it. When the beetle surfaced for air once again, Fidget pecked it, but
missed. The frightened beetle rushed to the bottom and disappeared into the
thicket, and Fidget began to look into the water again, hoping to catch at least
anything edible. The movement near the bottom did not escape his attention.
A shadow moves across the stones: it seems that a piece of the bottom has come
to life and swam. However, it is not a trick of vision, but a living being –
a young neohanasaki individual. Fidget vaguely remembered that there could be
danger in the water, but now that he has become big enough, he is not threatened
even by an adult neohanasaki. Ripples and sun glare on the surface of the water
make it difficult to see, but Fidget still noticed where the creature he saw
disappeared. Almost up to his belly in the water, he wandered to the reeds,
where he last noticed the shadow of an underwater creature. Previously, Fidget
never hunted in the water, but now he has become less picky and clings to any
opportunity to get prey. When Fidget is walking in shallow water, clouds of
silt and sand rise from the bottom, which are carried away by the current. After
taking some, Fidget felt a creature touch his feet. He looked down, and noticed
the wriggling body of an underwater creature right below him. He noticed where
the flat creature swam, took another step, getting bogged down in the sand,
and struck with his beak. Hunting in the water is a strange feeling for a creature
accustomed to hunting on land. The water got into the Fidget’s nostrils, and
from the pain the bird abruptly pulled its head out of the water and sneezed.
Any heron would have struck the prey much more gracefully than Fidget, but it
is unlikely that it would have dared to attack the prey that Fidget chose for
himself.
After sneezing several times, Fidget looked into the water. He saw that near
the bottom something was swaying slightly, casting a shadow. Fidget came closer
and touched this object with his foot. He felt a familiar sensation – the touch
of something slimy, but this time motionless. Fidget carefully targeted and
snatched a young neohanasaki from the water. Fidget’s beak pierced its head
and killed it on the spot. An accidental and almost aimless blow allowed the
bird to get a good lunch. Fidget hardly holds its prey – the carcass of the
neohanasaki is quite heavy and slimy, it constantly slips out of the bird’s
beak. Quickly getting ashore, Fidget threw the prey on the ground and began
to peck it, pressing it with his foot. Perhaps Fidget is just very hungry, but
it seems to him that the meat has a good taste. The meat of neohanasaki is very
tender, and the skeleton is rather weakly ossified; it easily succumbs when
Fidget tears off another piece of meat.
To the side, the familiar flapping of large wings and then two sharp, raspy
voices are heard – a pair of eagle keas accompanying Fidget has found their
patron, and both birds reckon upon the remains of his lunch. However, it is
unlikely that they will get anything edible – Fidget greedily tears up the prey
and swallows it in large chunks. When one eagle kea approached the feasting
predator too carelessly, Fidget fluffed feathers on his head and neck, and snapped
his beak menacingly. At such moments, it is dangerous to be near him, and the
parrots moved away from him. The carcass of the neohanasaki disappears into
the Fidget’s stomach piece by piece. Finally, when only the head remained of
the prey, Fidget finished his feast. He wandered into the nearby bushes to rest
properly. A long-forgotten feeling of satiety made him lazy and sleepy, and
the bird decided to find a place to rest.
When Fidget left, the eagle keas approached the remains of his prey. They got
almost nothing edible – only the head of neohanasaki with scraps of meat, and
several pieces of amphibian’s intestines. The skull crunched in the beaks of
the parrots, and then one of the birds picked up a piece of intestines, covered
with the ground, and swallowed it. To eat something else, the birds must look
for prey themselves. But they will not abandon Fidget – it is much more profitable
for them to hunt with him.
Fidget has successfully survived the time of separation from his parents, and
he is already in his third year of life. His life has changed significantly
compared to the first year, when he just started living on his own. He successfully
passed through a critical period of life and managed to avoid death in the jaws
of predators or starvation. Now Fidget is already quite large – it is the size
of an adult male of his species. But he is still too young to participate in
breeding. The time, when Fidget lived on the border of the territories of adult
pairs of relatives, has passed long ago and now he has his own territory, which
borders are guarded jealously, and strangers are expelled. If necessary, Fidget
can get into a fight for territory with any of the relatives. But Fidget can’t
control all the borders of his territory at the same time, and strangers occasionally
enter his domain.
The branches of the shrub rustle, and another ruakapangi appears from them.
This bird is a little smaller than Fidget, and behaves much more carefully.
It shudders and looks around when hearing too sharp sounds, and tries to be
as inconspicuous as possible. This bird is a female. She is about a year younger
than Fidget, and began an independent life only recently. She was lucky to stay
in the family a little longer – the male who was her father was killed by a
marsupial pardus. Her mother, not having had time to form a new pair for the
breeding season, did not drive her daughter away, and this female managed to
survive the critical age while hunting with her mother. But this year her mother
had a new male, and a pair of birds, preparing for breeding, drove the young
female from their territory.
This female has a small sign – several white feathers grow on her head above
the right eye. They are inherited by Whitebrow from her mother. It can be seen
that the bird is hungry – noticing a large beetle, she pecks it and swallows
it with hard elytra. An experienced hunter might not even look at such a prey,
but Whitebrow clings to life desperately. Now she has a critical time – the
first weeks of independent life. So, she must apply all the hunting skills acquired
during family life in order to survive.
There is a rustling in the grass, and the stems are moving – a tiny shrew-like
hedgehog is sniffing the grass. This fussy animal must constantly look for food
– it has an intensive metabolism. A sticky slimy trace told this animal that
a large snail had crawled through the grass – it is a good prey for such a predator.
So, the shrew-like hedgehog ran after her. Catching up with a snail is a simple
matter for such a mobile animal. It quickly found a mollusc, and it was not
deterred by the fact that the snail shell has a too catchy color, white with
black spots. The shrew-like hedgehog attacked the snail, clinging to its creeping
sole, and in response immediately received a fair portion of sticky and smelly
foam with a burning taste. The garlic snail managed to escape from the enemy
once again, and the little beast will have to tinker for a while, cleaning the
snail’s terrible weapon from its head. At that moment, the animal lost its vigilance,
which immediately cost him his life. Absorbed in hunting, it did not notice
that a large bird was watching it. Whitebrow struck it one peck with her beak,
and immediately killed it. During her independent life, she has already had
to hunt these animals. Having got such a creature for the first time, she pricked
her tongue painfully with its spikes and left the prey. Later, she adapted to
swallow these prickly animals without problems. Shrew-like hedgehogs are quite
numerous in the forests and shrubs of New Zealand, and Whitebrow received an
affordable food source, having learned to hunt them.
Whitebrow carefully took the dead shrew-like hedgehog, turned it headfirst,
and swallowed it whole along with the spikes. She is very hungry if she is tempted
by such prey. However, hunting such creatures would help her survive. At one
time, Fidget survived precisely because he learned to hunt on his own while
still under the protection of his parents.
Being on someone else’s territory, Whitebrow should remain cautious – a meeting
with the owner of the territory does not promise her anything good. Unlike mammals,
ruakapangi does not use the sense of smell when communicating with relatives,
and cannot detect an outsider on its territory without seeing him. But these
predators have good eyesight, and their perception helps them to distinguish
movement especially clearly.
Fidget walks around his territory regularly, and he has already had to drive
away several times the strangers who decided to settle on his territory. A long
time ago, he was the tramp like they, and many times he had to flee from adult
relatives. But he grew up, withstood the difficulties of life in his youth,
and managed to acquire his own territory. If some more birds live on its territory,
food resources will quickly run out and all its inhabitants will starve. Therefore,
Fidget was very interested in the large bird footprints that he found once on
the riverbank. They are smaller than his own ones, but undoubtedly belong to
the bird of his kind. Sooner or later there must be a meeting, which consequences
will be quite obvious.
Maybe Fidget wasn’t looking for a stranger on his territory on purpose, or Whitebrow
kept careful, but, anyway, they met only a week after Fidget found signs of
the presence of a relative on his territory. During this time, Whitebrow successfully
hunted rabbits several times, and one eagle kea began to accompany her, eating
up the remains of her prey. It is possible that Whitebrow could live unnoticed
on the Fidget’s territory much longer, but the eagle kea, constantly accompanying
her, is too noticeable from afar. So it was this one who led Fidget on the trail
of the stranger.
Fidget was hunting when he noticed a lone eagle kea perching on a tree and carefully
looking down. On this day, Fidget managed to catch only some lizards and a certain
small rodent. Therefore, he was looking for more substantial prey. The presence
of a large predatory parrot, which is too patiently waiting for something, perching
on a branch, can mean only one thing: a certain predator is eating its prey
under a tree. Of course, it may well turn out to be a large marsupial pardus,
from which it is better to stay away, but it may also be a relative or a small
predator, which you can try to attack and take away prey. Therefore, Fidget
decided to get to know what the eagle kea expects for. He began to approach
the tree cautiously, looking at the bird, cautiously ducking and ready to run
away at any moment if the meeting was too dangerous. Fidget was approaching
the tree, using all the shelters along his way. Finally, he looked out from
behind a bush, and saw a relative who was pecking at a rabbit carcass, clearly
taken from some predator. The fear disappeared instantly, and the feeling of
territoriality leapt up in Fidget. Despite the fact that the stranger turned
out to be a young female, Fidget is very determined and aggressive. He is still
too young to form a family, and his reaction even to representatives of the
opposite sex is still simple and unambiguous. Fidget came out to meet Whitebrow,
snapping his beak and fluffing his feathers. Instinct prevents the use of weapons
against relatives, so Fidget does not beat Whitebrow with his beak. He just
displays to her, his own size, straightened out and shaking his fluffed feathers.
In response to his display, Whitebrow snapped her beak and shook her plumage
several times. Then Fidget rushed at her and pushed her with his chest away
from the remains of the prey. Whitebrow barely stood on her feet, and Fidget
turned around and began to step on her again, uttering an unpleasant screeching
cry. Under the Fidget’s aggressive onslaught, Whitebrow stopped trying to display
claims to the territory and began to retreat. Noticing that she is afraid of
him, Fidget redoubled his efforts to expel the stranger. He began to make false
attacks with his beak, from which Whitebrow barely managed to dodge. Then he
once again pushed the retreating female with his chest. His warnings are enough
for the female to understand that she has nothing to do in this territory. Whitebrow
turned around and ran away, hearing the patter of Fidget’s feet behind her.
He drove the female to the border territory, not letting her stop. When the
female ran away, Fidget walked several times through the “unclaimed land” that
separates his possessions from the territory occupied by a breeding pair of
birds that were slightly younger than his parents. After looking around and
making sure that the female was not going to return, he returned to his territory
and in a few minutes completely forgot about the existence of Whitebrow. For
now, Fidget does not need competitors, and he is not going to share his territory
with anyone.
Late spring in New Zealand is a time of change. At this time, most of the local
animals bear offspring. Ursine cuscuses bear offspring in the winter, completely
unnoticed by others. At this time, they are in a state of light winter sleep,
and interrupt it only to clean the brooding pouch and feel how an underdeveloped
newborn joey crawled into the pouch and attached to the nipple. In the spring,
when coming out of hibernation, there are already several fairly well-developed
joeys in the brooding pouch of each female. The offspring of marsupials develop
slowly, and only at the beginning of summer the young animals will be able to
leave their mother’s pouch to continue living on her back. Other mammals, from
among the placentals, bring much more developed offspring. Ultradama females
gather in large herds for fawning – it’s safer this way for them. Females emit
special odors that synchronize the development of unborn cubs, and the offspring
of the ultradama are born in a very short time – all females in the herd calf
for two to three days.
At this time, the ultradama herds are constantly accompanied by predators and
scavengers. If a fawn is born dead, it is quickly found by eagle keas, eating
its corpse in a matter of hours. Sometimes these parrots drive newborn fawns
away from females and attack them. From time to time, the spotted back of a
marsupial pardus flashes in the bushes near the ultradama herd. The beast is
not interested in the offspring of ultradamas, but in adult females weakened
after the fawning. Sometimes females have postpartum paralysis, and they cannot
walk normally. Such prey is easy to catch, and an orphaned cub immediately falls
prey of other predators. Among the carnivorous animals accompanying the ultradama
herds, ruakapangis are often found.
Fidget watches the herd, choosing his prey. He noticed that one female with
a fawn had moved away from the main herd. It is very dangerous to rush into
the herd for prey – protecting their own posterity, ultradama female rears up
and beats the enemy with her front legs. She lacks the same spectacular-looking
and dangerous antlers as the male, and the female of this species is much smaller
than the male, but the blows of her hooves are very dangerous: sometimes a careless
ruakapangi can pay with its life for a mistake during the hunt. Fidget knows
what an angry ultradama female is – once in his childhood he had to escape from
the hooves of this beast when he, being only a fledgling, inadvertently moved
away from his parents and approached an ultradama female with a fawn. But he
knows how to organize an attack correctly, and the best target for his attack
is a fawn of the female grazing outside the herd. He is afraid of an adult female,
which is larger and stronger than him, and tries to choose a good moment to
separate the fawn from its mother. Ultradamas make a network of trails in the
bushes, which they use from year to year. Some trails become overgrown over
time, and an adult animal cannot walk along them. But the smaller ruakapangi
easily makes its way through the bushes thanks to the streamlined body shape
and narrow head. Fidget uses the trails of the ultradama to get closer to the
herd, remaining unnoticed. He hides in the bushes, trying not to expose himself
to the animals. In addition, ultradamas do not distinguish some colors, and
Fidget with his mottled plumage, frozen against the background of bushes, is
almost invisible to this deer.
Fidget creeps closer to the chosen animals. He tries to use the old trails of
ultradamas, not showing up on the wide trails that these animals use. The female
and the fawn do not notice his approach, and the rest of the herd also seems
to be confident in their safety. It is enough for at least one animal to “bark”
so that all adult animals become alert, and the fawns rush to their mothers,
seeking protection. But everything is calm so far.
Ultradama has relatively long and narrow jaws. This animal feeds on soft vegetation
– mixed herbs and foliage of shrubs. Therefore, animals have to stay in places
where it is convenient for predators to hide. Animals compensate for this circumstance
by keeping a large herd, in which there is always an individual who notices
the enemy in time. However, Fidget still remains unnoticed and gets closer to
its prey. When the fawn moved too far away from its mother, Fidget decided to
attack it. He jumped out of hiding and rushed to the fawn. At the last moment,
the female noticed him and ran after him, but Fidget caught up with the fawn
before her, and inflicted a deep wound on it with his beak. The fawn screamed
in pain in a shrill, trembling voice and rushed into the bushes, while Fidget
ran away and stopped. Somewhere in the ultradama herd, one female noticed him
and began “barking”. Her voice was joined by the voices of several more individuals,
and soon there was a deafening noise over the bushes. The female, having lost
sight of her fawn, began to call it, looking at Fidget at the same time. He
tried to keep his distance to avoid provoking the aggression of the female,
and at the same time he had to determine by ear where the wounded fawn was.
When the voice of the ultradama fawn was heard in the bushes, responding to
the voice of the female, Fidget immediately continued chasing it. With several
long jumps, he managed to slip past the ultradama female before she launched
an attack on him, and the pursuit of the fawn continued in the bushes, where
the ultradama female could do little to help her offspring. Fidget managed to
drive the fawn away from the female, and the goal of the hunt was almost achieved.
The wound on the side of the ultradama fawn was very deep, and there was a red
streak of blood on its spotted hide. It was getting weaker by the minute, and
Fidget easily caught up with it. Hearing the rustle of branches, the ultradama
fawn rushed away, and Fidget ran after it. He chased his prey through the bushes,
getting closer to it every second. Finally, the ultradama fawn tripped over
a root and fell, breaking its fragile leg bones. The next moment, a peck of
Fidget’s beak pierced its skull, and the fawn died. Somewhere on the outskirts
of the bush thickets, an ultradama female wanders, beckoning her offspring.
But she doesn’t know that it will never respond to her voice again. A lot of
ultradama fawns die every year, and their death is part of the natural balance
in the habitat of the ultradama deer.
Fidget dragged the prey away into the bushes and began to peck it. He heard
the flapping of huge wings, and noticed how a pair of eagle keas, his constant
companions, perched on the branch of a small tree nearby. Usually they always
helped him hunt and did not interfere with eating. However, now they are more
of a nuisance than helpers.
Ruakapangi is not the only one watching the eagle keas. Another predator also
heard the noise of the chase and saw two large birds perched on a tree and began
to look down somewhere, not flying away for a very long time. This predator
is the marsupial pardus, a huge old male, expelled from the harem by a younger
rival, but has not yet given up the fight for life. Now that he is forced to
live alone, it has become much more difficult for him to provide himself with
food. Previously, he could rely on the coherence of the actions of the members
of the group where he was the leader, and his group took even such giants as
adult taurovis. However, now he has to spend a lot of effort to eat his fill.
He uses a variety of hunting techniques and often monitors eagle keas, determining
the presence of prey by their behavior. When the opportunity arises, the old
marsupial pardus uses the prey of other predators – taking advantage of its
superiority in weight and strength it easily drives them away and takes away
their food. Noticing that the eagle keas are showing interest in something hidden
behind the bushes, the predator decided to check what is there. Looking for
prey, he sniffs the air, and his sense of smell tells him where to look for
prey. The old marsupial pardus is heading straight to the place where Fidget
began to eat the taken ultradama fawn.
Fidget easily tore the skin of the prey and began to peck at the meat. As long
as no one else encroaches on the prey, he is absorbed only in food. Fidget tears
off and swallows pieces of meat, enjoying the food. Once he had to starve, but
now he is an experienced and strong hunter, able to feed himself. But, alas,
middle-level predators like Fidget often have to feed larger and stronger predators
against their own will.
Eagle keas screamed in squeaky voices and took off. Hearing them, Fidget raised
his head and looked around. He noticed some movement in the bushes – obviously,
the animal, which he could not see well yet, was the cause of the parrots’ fright.
Not knowing whom he would have to meet, but determined to protect his prey,
Fidget fluffed his feathers and began snapping his beak. He kept his eyes on
the animal that was approaching him, hiding in the bushes. Finally, the uninvited
guest came closer, and Fidget felt fear. There was no doubt: he had been familiar
with the spotted furry skin of this animal, with its large eyes, long tail and
clawed paws since childhood. The marsupial pardus is the only predator species
in New Zealand that is dangerous for an adult ruacapangi.
The marsupial pardus male inhaled the air through his nostrils with pleasure.
He smelled the appetizing flavor of the blood and flesh of the ultradama fawn.
The meat of this animal is very tasty, and the marsupial pardus often hunted
such animals in its best years. He was only afraid of the adult males of this
deer, but later, when he became the head of the clan, he easily killed even
such animals. The predator looked at the young ruacapangi male, who fluffed
his plumage and tried to protect his prey. Even in his youth, he did not consider
these birds as serious opponents, and sometimes even attacked them and ravaged
their nests. It is unlikely that this creature will be able to stop him. Therefore,
the marsupial pardus boldly stepped forward.
Fidget tried to protect his prey until the last moment. But he knew that he
was unlikely to be able to do it. In the memories of his early age there was
a moment when his parents tried to drive away such an animal, saving him and
another chick, which was in their brood at that time. Then two adult birds barely
managed to drive away a predator that was smaller than this giant. Now he has
to retreat when an old marsupial pardus male approaches his rightful prey. Finally,
the situation becomes critical – the predator is too close, and attacking him
means endangering Fidget’s own life. Caution takes over, and Fidget makes a
quick decision – he leaves the prey and runs away. The marsupial pardus did
not even pursue him – he picked up the prey left by Fidget from the grass and
disappeared with it into the bushes.
The clan, which this male belonged previously, lives in the same territory as
Fidget. Marsupial parduses hunt larger and stronger animals than ruakapangis,
so they do not compete with these birds. There is a very tense relationship
between these predators – marsupial parduses attack ruakapangis and often take
away the prey of these birds, taking advantage of superiority in physical strength.
But ruakapangi can hunt animals that the marsupial pardus will not be able to
catch up with – orovises and young ultradamas. But the marsupial pardus, losing
ruakapangi in speed, uses brute force when hunting, and then adult taurovises
and huge ultradama males inaccessible to ruakapangi often become its prey.
A herd of taurovises grazes in the river valley. These animals have chosen a
rich forage area, where large herbaceous plants, shrubs and trees are found
in abundance. In the middle of the day, the animals get hot, and they escape
from the heat in the water. The animals enter the river, raising clouds of silt
and sand from the bottom. Thanks to their wide hooves, they do not get stuck
in sand and marshy swampy soil, and most often live in wet areas, thereby avoiding
competition with ultradama. In the water, taurovises can afford to be careless
– there are no animals in the rivers of New Zealand that can attack them. Large
New Zealand predators also do not hunt in the water, and neohanaszaki does not
pose a danger even to a newborn taurovis calf. Adult neohanasakis and juveniles,
which have barely developed legs, hastily leave ambushes at the bottom of the
river when they hear the heavy tread of these herbivores. Taurovises enter the
water up to their bellies, stand in the water for a while, enjoying the coolness,
and then lie down, and only their heads and backs remain on the surface of the
water. Adult animals move farther from the shore, and the young ones prefer
to frolick in shallow water. Taurovis calves arrange noisy games in the water
– they jump after each other, raising clouds of spray, rear up and fall into
the water with force, or swim near their parents, which doze lazily in the water.
Taurovises willingly eat soft aquatic vegetation. The riverbed is overgrown
with eel grass, and its foliage sways in the current like long green ribbons.
This aquatic grass, introduced by people millions of years ago, could easily
block the river current with its dense thickets and turn shallow waters into
swamps. However, taurovises and other herbivorous mammals that feed in the river
regularly thin out the thickets, protecting the riverbed from overgrowth. Animals
pull out this grass in large bunches, but this does not cause damage to the
thickets – the fast-growing plant restores the biomass soon. Also, the favorite
food of taurovises is coastal reeds. Animals easily pull bunches of them out
of the soft soil and chew them whole. They especially love the sappy bases of
the stems and rhizomes of the reed.
The head of the herd, a large male, keeps order among the animals subordinate
to him. He lazily chews the soft vegetation, casting glances at the shore and
the reeds. He has repeatedly faced attacks by predators hiding in coastal thickets.
He has a long scar on one side under his fur – once, many years ago, a young
marsupial pardus attacked him in the riverine thickets. At that time, the taurovis
male escaped, having made a bolt into the river in fright and the predator avoiding
the water had to let him go. For many years, having become the head of the herd,
the taurovis male remains cautious when near water. Other individuals from the
herd under his control also rest in the river channel and in shallow water.
At this time, small birds gather on the backs of taurovises and search for parasites
in their fur. They behave very boldly – they jump on their heads, look into
the ears and nostrils of taurovises, and even carefully clean the fur near the
eyes of the animals. Bone “visors” formed by overgrown frontal bones grow above
the eyes of taurovis, and parasitic insects often settle under them. So, the
birds carefully take them from there, relieving the itch, and at this moment
the taurovis freezes, allowing the bird to search freely for parasites. In addition,
birds have sharper eyesight, and notice the approach of a predator earlier.
In the evening, when the heat of the day subsides, taurovises leave the water
and graze on land. These herbivores consume a large amount of plant food, and
almost all their free time is occupied with eating. Even at night, from time
to time falling into a deep sleep for some minutes, these animals do not stop
ruminating. Young animals live much easier than adult animals. Among the herd,
several calves are frolicking next to the females. They only taste the food
of adult animals, and the basis of their diet is nutritious milk rich in fat.
On such a diet, they grow quickly and have a lot of free time, which they spend
for games. They run after each other around adult animals, and even hit legs
of their mothers with their foreheads with a run. While they are small, they
are forgiven for such pranks, but when the juveniles grow up, he will have to
take the lowest step in the hierarchy of the herd. There are already such animals
in the herd: two larger males of three years of age. These animals are already
old enough to do without maternal care, but they are still too weak to break
through to the highest levels in the hierarchy of the herd. They are busy with
not calf games at all – young males measure their strength, butting with their
wide foreheads. Their blows are still weak, and their foreheads are not so wide.
The forehead of an adult taurovis looks more like an anvil. It is slightly convex,
very wide and formed of thick skull bones. Such a forehead withstands the loads
associated with the mating fervor of huge males, and if necessary, a blow of
such a forehead will easily crush the bones of a predatory beast if it unsuccessfully
attacks this beast.
Taurovises are careful – they often sniff the air, trying to detect signs of
the enemy’s presence in advance. However, evolution equalizes the chances of
predator and prey – in response to the appearance of cautious and strong prey,
an intelligent and secretive predator that knows how to kill evolves. Millions
of years before Neocene, in the early historical epoch, the largest predator
of New Zealand was a giant eagle that hunted flightless moa birds. In Neocene,
the main predator of New Zealand is the marsupial pardus, the only animal capable
of killing taurovis. Ruakapangi rarely dares to hunt the cubs of this giant,
and the marsupial pardus keeps taurovis of any age in awe, up to mature males
in their prime. Grazing taurovises do not notice that they are being watched
by several predators at once, which hide in the thickets. Predators see each
other well, and act as a unit. They hunt as a group – this is a more effective
way of hunting, more often leading to success.
A clan of marsupial parduses surrounds the taurovis herd. Predators try not
to give themselves away with unnecessary movements. They freeze in the bushes
for a long time, and their spotted skins serve as an excellent disguise. The
main task of predators is to choose a prey, isolate it from the herd, and kill
as quickly as possible. The clan of marsupial parduses is a family group run
by a young strong male. All the females of the clan are related to each other
– these are two sisters and two their daughters. The male, the clan ruler, came
from the outside about two years ago. He drove out the old male and killed several
of his cubs, which by that time had grown up enough and left the mother’s pouch.
Therefore, now the only thing that connects an old male living on the edge of
the clan territory with his former family is one cub, which was just a newborn
at the time of the accession of the young male, and therefore escaped death
while being in the mother’s pouch. The other cubs are the offspring of the new
clan master. They do not participate in hunting, staying away from the taurovis
herd.
Marsupial parduses gradually close their round-up. It seems that taurovises
did not notice them, and the clan has the opportunity to complete the hunt successfully.
While the adult taurovises are feeding, browsing the leaves of the shrub, the
young taurovises have begun to sort out their relationship again. They behave
like adult animals during the rut: they roar, dig the ground with their hooves
and shake their heads. They display each other foreheads that have just begun
to grow in width, and then rush at each other and lock their horns. For a while,
they try to overturn each other, standing up on their hind legs and shaking
their heads from side to side, but then they go away of each other and begin
to display themselves to the opponent again. Their duel is still of a playful
nature – the animals have not yet reached puberty and their maximum size, so
they cannot harm each other. However, they were seriously carried away by this
game, and did not notice that the herd gradually dispersed, and there was no
adult animal left near them. However, it was noticed by the predators surrounding
the herd, and the hunt began.
At once two marsupial pardus females burst into the herd and rushed through
it, scaring away adult animals. In the first seconds, taurovises cannot understand
what is happening and roar anxiously. The herd of giants is panic-stricken,
and this is exactly what the predators need. Marsupial pardus females growl
and make aggressive attacks on animals that approach them. Their goal is quite
definite – to prevent the herd from uniting. The little taurovis calves rushed
in a panic to their mothers, counting on their protection, and the females cover
them from predators with their bodies. Other animals retreat from the marsupial
pardus females, and almost the entire herd gets together. Only two taurovis
males, who had gotten into a power play some minutes ago, remained outside the
protection of the herd, and now their lives are in danger. They become a target
for another female, who was waiting for the opportune moment in an ambush on
the other side of the herd. When she jumped out and darted to the young males,
they rushed in different directions, roaring anxiously. The females, who scared
the herd away, also joined in the chase. One male managed to break away from
his pursuers – he ran faster, ran across the road of one of the female marsupial
leopards chasing them, turned towards the herd and soon joined his relatives.
The second male was left alone, and all the attention of the predators switched
to it. Marsupial pardus females did not try to catch up with it, but when the
animal tried to turn towards the herd, the predators began running between it
and the rest of the herd, preventing the taurovis male from finding salvation
among its relatives. It has to run only forward, but he sees that he is overtaking
its pursuers. It seems to the young taurovis that it managed to outrun the predators
and escape, but actually it is not: it is running towards its own death. The
marsupial pardus females drive it farther away from the herd, directing the
young taurovis towards a tall tree that rises alone above the thickets. On one
of the branches, another hunter, to whom the right of decisive blow belongs
– an adult male, the head of the clan – is already waiting for it. Females carry
offspring in brooding pouches; therefore they do not risk attacking a large
animal for fear of damaging their cubs. They are assigned only the role of beaters.
They had done an excellent job – the young taurovis runs to the right place.
One by one, marsupial pardus females switch from running to walking. Taurovis
also stops. It is tired and breathing hoarsely, and its sides rise and fall.
Taurovis sees that somewhere behind it the bushes are moving, and the backs
of its pursuers flash among them. Therefore, it continues to escape from the
marsupial pardus females, but already at a walk. It’s tired, but the predators
can’t keep chasing at the same speed either. However, they do not need it –
the marsupial pardus females see the head of their clan carefully sneaking among
the branches. Taurovis simply does not understand that death can also come from
above.
The marsupial pardus male jumped on its neck with one precise leap, tore its
sides with his claws and inflicted several strong bites on its back. An unexpected
sharp pain pierced the body of taurovis, and it rushed through the bushes, leaving
blood stains on them, and carrying a terrible rider on its back. During the
running of the taurovis, the male holds on to it, clutching with his claws,
and continues to bite its spine.
The tactics of killing prey in the marsupial pardus is very simple – with strong
incisors it bites through the medulla oblongata and spinal cord of prey. The
giant ultradama male with heavy antlers dies from one precisely inflicted bite,
but taurovis is protected in this respect from the attack of the marsupial pardus.
The skin on the back of the taurovis’s head is very thick, and the base of the
skull is strong enough to withstand heavy loads – taurovises fight each other
by locking horns. Here, the usual way to kill prey does not work immediately,
and the marsupial pardus male is in great danger during such a hunt.
Blood flows down the shoulders of a young taurovis, its skin is torn by the
powerful teeth of the marsupial pardus, and the animal gradually weakens. The
marsupial pardus male has clung tightly to the back of this beast, and blood
is pouring from deep wounds inflicted by his claws and teeth. Finally, the male
managed to sink his teeth into one of the cervical vertebrae. There was a faint
crunch of bone, and the big animal fell. At the moment of the fall of taurovis,
the marsupial pardus male jumped off it. When he approached his prey, taurovis
was no longer breathing, and one of its eyes stared fixedly at the sky and glazed
over. The male licked the blood flowing down the side of the prey and waited
for the rest of the clan members. He managed to kill taurovis with almost no
losses – only one paw was bleeding from a wound inflicted, apparently, by a
branch, when taurovis was carrying the predator on its back, pushing through
the bushes.
Branches rustled nearby. The marsupial pardus male raised his head and sniffed.
His sense of smell told him that there was no danger – it was the females of
his clan gathering. They come out of the bush one by one, and surround the defeated
taurovis. The females are very tired – they are breathing heavily. Not every
time their hunt ends with such luck, but now their efforts have been crowned
with success.
In the distance, the anxious voices of the taurovis herd can be heard, which
sound fainter and fainter. Frightened by the appearance of predators and the
smell of blood, the taurovis herd goes away from such a dangerous place. Not
paying attention to them, the clan of marsupial parduses started eating. The
animals easily tear the tough skin of taurovis with their claws, and greedily
bite into the warm meat. They broke away from their prey for a few seconds when
a rustle was heard in the bushes again. Another female appeared near the clan’s
feast place. She did not take part in the hunt, but the clan members do not
express any aggression towards her, and she freely approaches the carcass. Everything
is explained very simply: a cub is riding her back, clutching her fur tightly
with its paws. After this female, several more young animals appear. They are
still too small to hunt taurovis, but they can count on a part of the common
prey.
These animals eat meat in a rather unusual way – they not only bite it off,
but also tear it off with their clawed front paws, and then bring it to their
mouths while sitting on their hind legs in an almost vertical position. Marsupial
parduses eat quietly – all the prey belongs to their clan, there is enough meat
for everyone, and there is no one on the islands who could encroach on their
prey. However, there are many creatures, who want to finish the leftovers. The
most numerous of the carrion hunters are the ubiquitous eagle keas. These parrots
watch each other and quickly gather to the place of successful hunting. A flock
of birds is circling in the air, and several dozen of these parrots perched
on a tree that shortly before served as an ambush site for the marsupial pardus
male. Seeing that the prey of predators is large, all pairs of eagle kea living
within a kilometer from this place gather for a feast.
Soon, marsupial parduses get full to the brim and go away, leaving the remains
of prey. The meat they have eaten will be enough for the next day, and then
they will have to go hunting again. When the last of the predators disappeared
among the bushes, the carcass of taurovis immediately disappeared under the
bodies of eagle keas gathered for a feast. Screaming loudly, the parrots began
to tear up the remaining meat on the carcass. Their voices attract other carnivorous
animals, which are not averse to profit from the remains of someone else’s prey.
Fidget is among them. The parrots retreat when the ruacapangi male approaches
the carcass – the birds fully recognize his priority, and try not to come into
conflict with him. Fidget does not pay attention to these noisy birds. He chooses
the soft parts of the carcass for himself, because his straight beak does not
allow him to tear the meat directly from the bones. He tears off the meat, jerking
his head and swallows it greedily. The parrots did not fly away at all when
he appeared – they continued the noisy feast, and only stay out of reach of
his beak. Fidget likes the taste of young taurovis meat, but in case of hunger
he would not refuse carrion already begun to decompose. After eating, he goes
away, and the parrots continue the feast. Having already moved away to a sufficient
distance from the carcass, Fidget heard a shrill alarm cry of eagle kea. He
did not check what happened there – these parrots are usually very brave, and
anxiety means that something is happening near the carcass that really scared
them.
An old marsupial pardus male, a long-time enemy of Fidget, also found this carcass.
If he had come a little earlier, Fidget would have had to leave food and run
for his life. He is afraid of this beast, which is very cunning and still strong
enough to hunt down and kill Fidget. In addition, he has no permanent shelter
and it is unknown where and under what circumstances he may be encountered.
Therefore, Fidget was very lucky to avoid meeting him near the remains of the
taurovis carcass. The old predator noticed eagle keas gathering for a feast,
and hurried to the share-out of the remains of the taurovis carcass. The loud
voices of parrots mean that there are no other predators nearby, so the old
marsupial pardus is not afraid that he will have to prove his right to share
of this meat. He walks to the carcass, scares away the parrots, and begins eating.
He rarely gets an opportunity to eat his fill without too much effort – after
being expelled from the clan by a young rival, the old beast ate only scraps
or preyed small animals. The prey of smaller predators that he took from them
was also small, so he had to search for food all day. So, now he has the opportunity
to eat his fill. With strong front incisors, the beast gnawes the meat from
the bones of taurovis, and nibbles the ribs. But these remnants are not enough
for him, and he easily turns the carcass to the other side, where it is less
eaten. Here he gets a lot of meat from the legs and sides of the taurovis carcass
– this is enough to satisfy his appetite. After the feast of the old male, the
parrots will have only some meat, an inedible skin, and bones from which they
can easily get bone marrow. Marsupial parduses do not crack the bones of their
prey.
Small predators like ruacapangi find it difficult to live alongside stronger
and more aggressive predators, such as the marsupial pardus. However, their
chances of survival are equalized by the fact that marsupial parduses depend
on the abundance of large prey. Each clan of these predators occupies a large
territory, and their encounters with ruakapangi are rare enough to harm the
populations of these birds. In addition, ruakapangi is characterized by flexible
behavior and can inhabit places where it is difficult for both large herbivorous
animals and their hunters to live.
Fidget is very lucky to stay alive in the first months of life, when many chicks
die from various small predators. He successfully survived the second critical
period, when he began to lead an independent life. Now Fidget’s age is about
five years. His life is changing – in addition to hunting and protection from
enemies, new motives of behavior appear. The body of Fidget has entered the
time of maturity, and the fifth spring of life changes its perception of the
world around him. While earlier he considered the protection of the territory
from his relatives to be his main duty, now he would not drive all his relatives
in a row from his territory. Perhaps Fidget is not yet aware of the changes
in his sense of the world around him, but he is gradually being embraced by
a new feeling that has not yet fully manifested itself.
Fidget is still roaming around his territory, hunting as needed. For five years
of his life, he learned to track down prey and kill it quickly and without harm
to himself. His territory is rich in prey – there are several colonies of castle
rabbits within its borders, and Fidget regularly visits them one after another,
gathering a bloody crop from them. In the forest he finds a lot of small animals
– lizards, small mammals and chicks of various birds. On the banks of the river
and in swampy river bays, he catches aquatic animals – he really likes the tender
meat of neohanasaki. With his strong beak, he cracks the shells of river crabs
and crayfish like nuts. Only few ruakapangis have mastered catching water animals,
but Fidget, thanks to his curiosity, has mastered this activity perfectly and
does not remain hungry, even if his hunting on land was unsuccessful.
Fidget takes view of his territory. In the distance, on the riverbank, ultradamas
roam. Males have only just begun to grow their impressive antlers, and females
are caring for fawns born recently. Fidget prefers not to mess with the males
of this huge deer, but he hunts fawns on occasion. Manure heaps lie in the bushes
on a wide path, and large round footprints are seen around them – a taurovis
herd has passed here. Adult animals are too large and aggressive for Fidget
to overcome them, but taurovis calves represent a tempting prey. Some ruacapangi
families hunt taurovis calves, although this hunting can be very dangerous.
Of course, marsupial parduses roam his territory, considering part of the Fidget’s
territory to be their own, but he has learned to avoid meetings with them, and
even benefits from the presence of these predators by eating the remains of
their prey. So he manages to taste the meat of taurovis and ultradama falling
prey of Fidget’s formidable neighbors.
Spring is coming into its own. The cool winter is leaving, the days are getting
longer and sunnier, and these changes in nature affect the Fidget’s behavior.
His life is on the verge of changes again, and they are no less than when he
left his parents and began to lead an independent life.
Inspecting his individual territory, Fidget is looking for prey. Therefore,
he immediately notices that the branches of the shrub are moving, although there
is no wind. This can mean one of two things – it is either a small animal that
can be killed and eaten, or someone of his relatives. Fidget couldn’t figure
out what it was, so he began to creep cautiously to the bushes, just in case,
being careful. If a marsupial pardus is hiding in the bushes, the meeting may
end in death, so Fidget is ready to flee at any moment. But when he took some
more cautious steps, the branches of the bushes stirred again, and a head poked
out of them. It is a small head on a flexible movable neck. It is a head with
a strong and slightly curved beak, similar to the beak of Fidget itself. It
is a ruacapangi’s head. Fidget saw that there was no danger, and decided to
find out more about this stranger. The other bird also took some steps towards
him. It came out of the bushes, and Fidget was able to get a much better look
of it. This bird is a little bigger than he is. It is a ruacapangi female. She
has a characteristic coloration mark – some white feathers grow over her right
eye. This is Whitebrow, whom Fidget has already had to meet once. However, at
that time the circumstances were completely different, and he just chased her
off his property. Now Fidget is not so aggressive towards her. He cautiously
approached Whitebrow, trying to keep his head lower than usual, and darting
wary glances at the female. Whitebrow managed to survive and even grew a little
larger than Fidget is. If she starts behaving aggressively, Fidget may get several
painful pecks, but the conquering of a new territory is obviously not a part
of the plans of Whitebrow. The memory of birds is very short: both Fidget and
Whitebrow simply do not remember that they have already met in this area about
two years ago in completely different circumstances. Now they are getting to
know each other, as if they are seeing each other for the first time in their
lives. Both birds are ready to form a pair and raise offspring, and aggressiveness
towards relatives fades into the background, giving way to the behavior more
important for the survival of the species.
Now Fidget felt what the changes taking place in his body meant. All the elements
of the puzzle came together to form a single picture – he just became an adult.
He did not feel the need to drive Whitebrow from his territory. On the contrary,
he would not let her go if Whitebrow decided to leave. Fidget carefully touched
Whitebrow’s plumage with his beak and froze. Whitebrow looked at him, and in
response touched the bare skin near the Fidget’s eye with her beak. It was an
important sign for both birds, signifying the absence of aggression. After this
touch, Fidget suddenly took off, ran some steps and spun on the spot, raising
his beak up. He performed one element of the courtship dance, just as his father
Sharpbeak danced in front of Harpy shortly before Fidget was expelled from the
family. Then Fidget ran up to Whitebrow, touched her plumage with his beak and
ran away to the side. Stopping, he looked at Whitebrow and shook his plumage.
Whitebrow accepted his rules of the game and rushed after him. This element
of courtship is very important for birds – while running, they assess the physical
condition of the future mating partner, and choose the best one, rejecting the
weaker one. It seems, Fidget meets the Whitebrow’s taste well – she barely succeeds
not to lag behind him. When he stops, Whitebrow also stops running, but stays
close to him, not moving away.
In the evening, Fidget and Whitebrow settle in for the night. They chose a place
to sleep in the forest, among the ferns. Whitebrow dug for herself a small hole
and lay down in it. Fidget decided to spend the night next to her – he began
to rake the ground with his claws next to the hole where Whitebrow got settled.
However, she almost immediately showed displeasure – Whitebrow grumbled and
slightly pecked Fidget some times, letting him know that he should keep his
distance for now. So, the young male retreated, choosing a convenient place
for himself not far from Whitebrow.
Over the next few days, the birds gradually strengthen the relationship that
develops between them. However, they still hunt singly, as before. After a successful
hunt in the riverine shallow water, Fidget brought neohanasaki meat in his stomach.
Whitebrow had never hunt near the river, and therefore never tasted the meat
of this animal. While treating her, Fidget regurgitated the meat and took it
with the tip of his beak – just like adult birds feed chicks. Whitebrow accepted
his rules again and crouched down to appear smaller. She lightly touched Fidget’s
beak with her beak, and then gently pulled the meat from his beak. Fidget held
it for some seconds, but then released it, and Whitebrow swallowed this morsel.
Usually, after such a ritual, the female begins to behave like an adult again,
but Whitebrow touched Fidget’s beak again, and he had to regurgitate some more
meat to treat Whitebrow. During this feeding, the birds took another step towards
each other – the female checked the manifestation of the parental qualities
of the male, and at the same time tasted meat that she had not eaten before.
At night, Whitebrow no longer objected when Fidget decided to settle for the
night next to her. She even preened the feathers on the back of his head while
he turned in the hole dug for the night.
As the relationship between the birds became even stronger, their ceremonies
towards each other became increasingly ritualized. Fidget continues courtship,
but gradually begins to bring completely inedible objects to the female instead
of prey meat, and the female does not reject them – this means that the material
side of the relationship of birds has gradually faded into the background, and
the presence of each other is more important to the birds. Fidget often walks
around Whitebrow, holding a twig or a dry fern leaf in his beak as a symbolic
gift to the female. Bringing such objects, Fidget bows to Whitebrow several
times, while tilting his head to one side and looking at her with one eye. Whitebrow
accepts these items with interest. She does not swallow them, but begins another
ritual – sitting down on the ground, she scrapes the leaf litter with her claws,
turning on the spot, and then sits down on the ground and slips the object brought
by Fidget under her body. This is a sign that the female is ready to build a
nest.
Unlike their ancestors, weka rails, ruakapangi nests not in a hole, but in a
secluded place in the forest, hidden from prying eyes. The bird is too large
to dig a burrow of a suitable size, and in due course of evolution its building
behavior has undergone significant changes. Birds build a nest together. Fidget
and Whitebrow dig a hole, scattering the ground far away. Then the birds line
the nest with soft material. Usually, Fidget is engaged in its preparation,
and Whitebrow has to trample it, forming the inside of the nest. Fidget brings
dry fern fronds, bird feathers, and even dried scraps of small animal skins
left over from the prey of local predators to the nest. One day the event happened,
for which both birds have been preparing for a long time – the first egg appears
in the nest. Whitebrow was a little scared of the new feelings of her body when
she laid it. After the egg lay down in the litter, she turned and looked at
it, and then touched its shell with the skin of her throat. Ruakapangi does
not incubate incomplete clutch, as owls do, for example. Therefore, Whitebrow
carefully raked the litter on top of the egg, and began to wander around the
nest. The appearance of Fidget returned from hunting caused some signs of aggression
in Whitebrow – she shook her plumage, and when Fidget tried to approach the
nest, stood between him and the nest, looking defiantly at Fidget. The male
stopped, dropped the rabbit he brought to the ground, and emitted a short cry.
Of course, his voice is well known to Whitebrow, and she calmed down after recognizing
Fidget. However, with the appearance of the first egg in the nest, Whitebrow
began to show displeasure when the male appeared too close to the nest. So,
Fidget had to spend the night separately from Whitebrow again, as in the first
days after their meeting. Over the next few days, two more eggs appeared in
the nest, and one morning, when Fidget woke up and approached the nest, Whitebrow
did not stand up, and met him only with a staccato cry, which she usually uttered
to express her displeasure. It was only at this moment that the Fidget noticed
that Whitebrow is not in a hole for spending the night, but in the nest. She
began incubating, and all the duties of supplying Whitebrow with food, as well
as protecting the nest from various nest ravagers and egg hunters, fell on Fidget.
At night, Fidget sits next to Whitebrow and gently, but persistently shifts
her to the side. At this moment, for the first time, he directly feels involved
in caring for the offspring that has not yet appeared – he touches the smooth
eggshell with his skin for the first time. All night the birds incubate the
eggs together, and in the morning, when Whitebrow leaves the nest, Fidget replaces
her and incubates the eggs on its own. In ruacapangis, the male and female spend
about the same time incubating the clutch, but towards the end of incubation,
the female stays in the nest longer.
Exactly five weeks have passed since the beginning of incubation. Birds do not
keep track of time, but they feel that a very important time comes. At night,
when Fidget wanted to get into the nest, as usual, Whitebrow did not let him
in. She pecked him several times, and her blows were very painful. Then she
growled in displeasure and stood up on the nest. At that moment, Fidget heard
some previously unheard sounds similar to the voices of small rodents that he
had caught earlier. He did not attach any importance to this, and wandered off
to look for a place to sleep.
Early in the morning, as soon as dawn broke, Fidget woke up, hastily preened
his feathers and went hunting. His usual prey is a castle rabbit. Fidget has
achieved great success in hunting these creatures. He knows how to arrange masterfully
an ambush near burrows, and kills these stupid creatures with one peck of his
beak. Sometimes lizards fall his prey, or he manages to find the remains of
the prey of marsupial parduses, on which the remains of meat are still preserved.
However, in this case, the key to success is to get to the remains of the carcass
on time. If you are late, eagle keas are unlikely to leave anything edible for
ruacapangi on the bones of the corpse. If you appear too early, you can find
the hunters themselves near the carcass, and then you will have to save your
own life. However, recently Fidget was a lucky hunter, and he always brought
food for Whitebrow busy in egg hatching. Fidget managed to kill a large castle
rabbit, and he headed for the nest, carrying this prey in his beak.
Whitebrow met him warily, as usual. Fidget had to respond to her voice to calm
down Whitebrow. When Fidget approached the nest, Whitebrow lowered her head,
fumbled with her beak under her body, and... took out the egg shell with the
remnants of the membrane from the nest. Fidget has not seen it before, but he
knows how to act in this case. He carefully took the egg shell, carried it away
from the nest and threw it into the bushes. As he was returning to the nest,
he heard sounds that he had not heard before. Undoubtedly, it was the voice
of Whitebrow, but she never made such sounds in the presence of Fidget – she
uttered the sounds similar to a quiet cooing. A twig snapped under the Fidget’s
foot, and Whitebrow called him in a quite familiar voice. When Fidget approached
the nest, Whitebrow continued uttering the same sounds that he had heard before.
Suddenly they were joined by other sounds that Fidget had already heard, but
did not understand their true meaning – he heard two squeaky voices, which were
responded by Whitebrow. When Fidget approached, she got up from the nest, and
Fidget saw what he and Whitebrow had to incubate the clutch for several weeks,
hunt and defend the nest. Two chicks, covered with black down, are sitting under
Whitebrow, not yet completely dried out and barely able to keep their heads
up. One more egg laid the first appeared infertile and nobody hatched from it.
It was lying at the edge of the nest, and all the attention of Whitebrow was
addressed to two small living creatures that carry the genes of both parents.
Until these creatures have grown up to realize the best qualities got from their
parents, they require only one thing – a relentless parental care.
One of the chicks stirred, opened its eyes and looked at Fidget. The circle
of life has closed – five years ago, Fidget came to the light, being the creature
like this, and now he has become a father. He will do his best to raise these
two chicks, and perhaps one of them will be lucky enough to survive the first
years of independent life just as Fidget did. In part, it will be possible thanks
to blind chance, but it will also gain advantages in the struggle for existence
thanks to the hereditary inclinations got from his parents. Then a new generation
of feathered hunters will populate the forests and shrubs of Aotearoa, the land
of the Long White Cloud.

Garlic
snail (Scorodonodora foetidissima)
Order: Stylommatophora (Stylommatophora)
Family: Ground snails (Helicidae)
Habitat: New Zealand, New Zealand, forests and bush of Both Islands.
Picture by Alexander Smyslov
The appearing of mammals in New Zealand is the new factor
for endemic flora and fauna, that existed without them within millions of years.
Animals introduced by people had changed the direction of evolution of ecosystems
of archipelago. Occurrence of various small mammals had caused the reduction
of number of large invertebrates endemic for these islands. Many species kept
by people in captivity, in reserves and nurseries, had quickly vanished after
human extinction, superseded by descendants of introduced species. But some
species of large invertebrates managed to survive – at them new protective adaptations
had appeared, permitting to resist to new neighbours.
Snails in most cases survived due to high breeding rate and passive protection
– strong twisted shell. Some species of snails became poisonous, and it also
raised probability of their survival. In human epoch small insectivorous mammals
had appeared in New Zealand, and as the answer, many species of ground snails
developed effective chemical protection against them.
This large snail with very appreciable white shell lives in forests of New Zealand.
Coils of shell are covered with longitudinal black dabs, and such colouring
is well appreciable from apart on the background of grass or forest litter.
But bright appearance is a part of protection of snail. If any animal disturbs
this mollusk, snail emits the unpleasant garlic smell which is frightening off
the aggressor. For this feature it has received the name “garlic snail”. But
protection of snail is not limited by smell: if the predator does not stop the
attack, snail secrets the caustic and sticky liquid sharply smelling as garlic.
In air this liquid thickens and it is very difficult to remove. Therefore garlic
snail is not afraid of attacks of small and medium-sized predators at all.
Garlic snail almost does not differ in appearance from other ground snails from
other parts of the world. At it there are shorter tentacles on head and wide
oral blades plentifully covered with receptors, allowing to find out even such
catch, which is hidden in ground at the depth of about 10 cm. Garlic snail is
the omnivorous mollusk with a bias in predating. It willingly eats delicate
greenery of ferns and other plants, and also mushrooms. This snail also eats
any food of animal origin, which it manages to find. But its special food predilection
includes various ground invertebrates and carrion. Hunting for ground animals
demands the special receptions which this snail owns. Similarly to police dog,
it finds with the help of keen sense of smell worm or grub digging not deep
in ground. Having defined the location of prey, snail plunges head in ground,
and starts to dig a tunnel of prey. Thus the head of snail works similarly to
body of earthworm – with the help of contraction of muscles it is extended and
forces the way forward; when the snail contracts muscles of back part of body,
head expands the hole.
Having reached the body of prey, snail uses the deadly weapon. In its mouth
there in fleshy tongue – it is the radula armed with several pointed teeth.
Teeth of garlic snail are similar to knifes: they lack of poison, but easily
cut the body of prey. Snail devours catch, not pulling it out from ground.
Similarly to the majority of ground snails, garlic snail is the hermaphrodite.
It lays large eggs in small portions, digging them in friable ground between
roots of trees where probability of egg founding or damage is less. For this
purpose snail digs by head small holes in ground the same way, as at hunting,
and digs them out after egg laying. Egg laying repeats every 7-8 days; the incubating
of clutch lasts about 2 weeks. Young snails at once lead predatory habit of
life and can emit caustic odorous substance. At first they eat very small invertebrates
– soft insects and small worms. They reach the size of adult snail at the age
of one year, and can live up to 5 years.
Neohanasaki
(Neohanasaki aotearoae)
Order: Tailless amphibians (Anura)
Family: New Zealand false salamanders (Virilogyrinidae)
Habitat: New Zealand, slowly flowing rivers and big lakes of Southern Island.
Picture by Alexander Smyslov
New Zealand false salamanders are the separate group of amphibians
generated in conditions of island isolation. From early Neocene their active
adaptive radiation began, and its result is the presence in New Zealand of several
variations of these animals, which occupy various ecological niches, avoiding
the competition with each other. The majority of New Zealand false salamanders
is presented by small animals, but one species represents large amphibian up
to one and half meters long. This species is named neohanasaki. “Hanasaki” is
the Japanese name of giant salamander, the large amphibian inhabited Japan Islands
in Holocene epoch. Neohanasaki is the largest species of “adult tadpoles” of
New Zealand.
New Zealand neohanasaki is similar to the prototype from Eastern Asia. At this
amphibian there is wide, flat and angular head, on which edges small eyes are
located. In corners of the mouth two short wattles with wide bases grow. At
neohanasaki, as at all representatives of New Zealand false salamanders, larval
features are kept: wide branchial apertures supplied with skinny valve, and
skinny fin bordering long tail. The tail makes more than half of general length
of this animal.
Skin of neohanasaki is knobby, and on each side of the body small plicas stretch.
When this amphibian moves, its skin waves, and it seems, as if the skin was
intended for larger animal. But there is a deep biological sense in it – skin
helps neohanasaki to breathe, especially in cold season. Neohanasaki moves in
water, bending the body wavy and pushing from bottom by short paws. Colouring
of neohanasaki is dark brown; throat and stomach are colored beige with small
brown spots. When this animal lies motionlessly at the bottom among underwater
plants, it may be mistaken for the piece of rotten tree trunk.
By its nature neohanasaki is inactive animal representing the ambuscader like
European catfish. Usually it hides under driftwood or motionlessly lies among
vegetation, expecting while the prey will approach to it itself to the distance
of resultative throw. This species does not pay attention to small fishes and
tadpoles, even when they twitch its skin. It hunts for large water animals –
crustaceans (river crayfishes and crabs), large fishes, and also medium-sized
tetrapods appeared in water. Its prey often may include related species of “adult
tadpoles”.
In spawning season this animal turns very active and mobile. Male gets bright
courtship dress: its stomach turns yellow with small black spots, and on tail
fin the line of jags grows. Trying to impress the female, male turns to her
by side and displays the splendid serrated crest on back. If the female is interested
in the male, he continues demonstration. During the second part of courtship
the male shows bright stomach to the female. It emerges to the surface of water,
swims above the site, and splashes by tail, declaring about rights to this territory.
From time to time the male pours the female with waves of water, displaying
the force to her. This species spawns eggs in big bush of water plants: male
and female creep in it together and simultaneously spawn sexual products.
The clutch of neohanasaki may number up to 500 – 600 eggs surrounded with mucous
mass. The male displays the care of posterity: it protects territory up to larvae
hatching, driving away or simply eating any animals representing danger to eggs.
From time to time it slaps by tail on the water surface – it is not only the
signal to applicants to keep farther, but also the way of enrichment of water
with oxygen. When from eggs tadpoles hatch, male does not abandon them. First
days of life tadpoles keep near its head, and male carefully protects them.
The top layer of male’s skin at this time starts to swell and to exfoliate.
Tadpoles eat it in the first days of life, and due to this feature their survival
rate in critical period is very high. The grown up posterity leaves male and
swim to the independent life full of dangers. The main danger for young neohanasaki
is its congeners: at this species cannibalism is advanced. Therefore till first
years of life the posterity keeps in shallow streams, where eats larvae of insects.
Sexual maturity at neohanasaki comes at the age of about seven years at length
up to 60 cm. Life expectancy reaches 90 years and more.
The idea about the existence of this group of animals is stated by Tim Morris, Adelaide, Australia.
Ruacapangi
(Antipodornis ruacapangi)
Order: Gruiform birds (Gruiformes)
Family: “Awful rails” (Deinorallidae)
Habitat: New Zealand, woodlands and forests.
Picture by Alexander Smyslov
Among the order Gruiformes only few species could endure the
human activity changing landscape, flora and fauna up to unrecognizability.
These ancient by origin birds appeared very sensitive to anthropogenous influence
and in human epoch number of practically all species had strongly reduced, and
some had died out at all. Representatives of rail family (Rallidae) have especially
suffered from people. Before human colonization of planet practically at the
each island of Pacific ocean endemic species of rails, moorhens (or gallinules)
were found. People had disforested islands, hunted birds, nests and chicks were
exterminated by constant people satellites – rats and become wild pigs. As a
result from some rail species at all only skins or only descriptions of travellers
were remained for science. But in any rule there are exceptions. And among rail
birds such happy exception there was New Zealand bird weka (Gallirallus australis).
This rather large rail has adapted to life near to the people, and sometimes
it even began to harm stealing chickens and ducklings at farms. Mice and rats
introduced by people also began to stay at significant place in its menu. This
courageous and curious bird had good chance to survive and used it when the
mankind has disappeared from the face of Earth.
The descendant of New Zealand rail weka had kept injurious habits and had turned
to frighten-looking creature resembling by something tiny variant of fossil
bird Phorusracus. The name of this bird – ruacapangi – is taken from folklore
of maoris, aborigenes of New Zealand: the huge mythical bird was named so.
Ruacapangi is a bird up to 1.5 m height weighting about 50 kg. In fauna of New
Zealand of Neocene epoch this is the largest New Zealand bird. Though Neocene
is relatively warm and humid epoch, climate of New Zealand is completely determined
by Pacific Ocean. Therefore summer on islands is rather cool and damp, and winter
is not frosty but also cool, and snow falls in mountains. Life in such conditions
had resulted at theappearance of bird – its feathering is dense and more similar
to wool. Only in tail straight wide feathers were kept though this bird does
not fly. Tail at male is longer, than at female. Colouring of ruacapangi feathering
is soft – feathers are brown with black longitudinal strips; back is darker.
Sides of head, forehead and throat of this bird are featherless and covered
with naked skin of flesh-red color. Because this bird is carnivorous, such adaptation
helps to keep cleanliness when bird eats prey. Beak is black, slightly bent,
thick at the basis.
Wings have disappeared already at ancestors of this species, from them only
reduced elements of shoulder grid and rudiment of shoulder bones were kept.
But inability to fly is compensated by good running abilities: ruacapangi can
accelerate momentum about 60 kms per hour at short distances. On legs of bird
short sharp claws providing coupling with ground during run and sharp turns
grow.
This bird is the largest predator of New Zealand. It attacks ground vertebrates
(basically descendants of species introduced by people), and also gathers carrion
at ocean coasts. By hunting habit ruacapangi is more similar to tiger than to
wolf: bird reluctantly chases prey preferring to attack it from an ambush, putting
short prompt impact.
Usually ruacapangi solitarily or by pairs wander at the territory searching
for food. From height of its growth bird looks around watching for carrion or
smaller animals. Basically small animals weighting up to 3-5 kg become prey
of ruacapangi though some birds (parents and grown up fledglings) can attack
larger and dangerous
animals in common.
Ruacapangis live in pairs keeping for all life. Male is smaller, but higher
and more harmonous than female. Cares of hatch are his occupation when female
hunts.
This wingless bird nests at the ground. Nest of ruacapangi represents deepening
in the ground up to meter in diameter and about 30 cm in depth. Pair of birds
in common digs it in ground among bushes, and covers with dry grass and moss.
In clutch there are 2-3 large rounded eggs (length about 20 cm) with motley
shell. The clutch is hatched alternately by male and female. The incubating
lasts 35 days. Chicks hatch advanced and covered by black down. They at once
abandon nest and start to eat. Parents feed them belching pieces of meat. During
feeding the adult bird holds a piece of food in beak, and chicks peck it. During
feeding they compete among themselves, pushing away each other from parents,
but it does not pass to the direct conflict (nestlings of cranes, for example,
fight among themselves to death). Young birds develop rather slowly: at them
feathers start to grow only at fortnight age. Nestlings keep with parents till
the next spring, all this time training in hunting receptions.
The family breaks up in the beginning of summer, and young birds before maturity
live solitarily. Sexual maturity comes at them at 5-years age.
Eagle
kea (Aquilopsitta horrida)
Order: Parrots (Psittaciformes)
Family: Nestors (Nestoridae)
Habitat: New Zealand, woods and mountains.
Picture by Carlos Pizcueta
Picture by Wovoka
Mass extinction of large ground predators caused by reduction
of number of their prey and direct human hunt has affected at the evolution
of many groups of vertebrates. Among various unspecialized omnivores species
appeared, more or less successfully mastered “speciality” of predator in different
ecosystems of Earth. In New Zealand, on islands of continental origin, one representative
of parrots occupied the ecological niche of large feathered predator.
It is the descendant of primitive local parrot kea (Nestor), known in human
time by predating bents. The Neocaenic feathered predator by validity has name
“eagle kea”: it has strongly changed in comparison with ancestor.
Eagle kea is rather large flying bird: its weight is up to 7 kg at wingspan
about 3 meters. For it soft colouring typical for ancestor is characteristic:
green wings with cross strips, brown head and darkly-green stomach. Tail of
this bird is wide and fan-shaped.
Paws of this carnivorous bird have kept structure typical for parrots - two
toes are directed forward, and two ones – back. The grip tenacity inherent in
these birds was kept, though now paws of eagle kea frequently grip not branches
or fern root, but body of catch. The eagle kea spends more time on the ground,
rather than its ancestors, therefore its paws are much longer, than at other
parrots.
Beak is black, maxilla is approximately twice longer than lower jaw. With the
help of long and peaked maxilla the eagle kea cuts catch slicing from carcass
pieces of meat. The bottom jaw is massive; with its help bird can crush bones
of catch and gnaw cartilages. Around of beak there is strip of naked grey-colored
skin protecting feathering from pollution by blood and meat juice.
Eagle kea feeds with most different live catch: it kills mammals and birds weighting
up to 20 - 25 kg. Bird does not refuse even “gratuitous entertainment”: it can
feed with carrion and gathers rests of catch of large local predatory birds
ruacapangi. Sometimes pair of eagle keas imperceptibly accompanies hunting birds
ruacapangi, hoping to profit by rests
of their catch. Eagle keas usually hunt in pair, only during nesting when one
of birds is busy with clutch hatching other bird hunts alone.
This large parrot nests in rock caves and in other places inaccessible to ground
animals. In clutch there are two large white eggs. Nestlings hatch helpless,
naked and blind. Parents entirely devote themselves to care of posterity: heat
nestlings serially, feed them belching semi-digested meat. When nestlings grow
up, adult birds start to accustom them to feeding by fresh meat, dragging to
the nest big pieces of catch. The posterity develops slowly: young birds fly
out from nest approximately half-year old, and after that about one year they
live with parents. Thus, birds nest alternate years. But the survival rate of
posterity at them is rather high in comparison with other parrots nesting more
often and having more nestlings in hatch.
The young birds flied off from nest study hunting receptions at parents. Thus,
these receptions are inherited such way from generation to generation. Tactics
of hunting happens rather various. Parrots are clever birds inclined to training.
The intelligence was one of the components which have permitted these birds
to take the important place in ecosystem of New Zealand. Each family develops
and keeps receptions of hunting, training posterity to successful tactics of
food getting.
At the flat district birds hunt young growth of local herbivores. If it is the
cub of any gregarious animal (for example, taurovis),
birds wait, while it will separate from group, and then, having chosen the moment,
try to drive it off farther. They frighten chasing animal, using their size
and loud shouts. If the prey aspires to return to herd, birds attack it and
put wounds, compelling it to run to needed side. Parrots prey small and single
animals, having hidden in bush or on the tree, and then attack them from ambush
like hawk. At the mountain slope eagle keas use limitation of moving abilities
of chasing animals. They try or to frighten chosen prey that it stumbles and
falls down or actively attack together also to push by impact animal from slope.
Similarly to wolves, eagle keas frighten away local hoofed mammals, orovises
grazing in mountains to determine, as far as animals in herd are healthy. If
any animal escaping from them runs downhill (it is easier to run so), birds
drive it until it will stumble against something or will put to itself casual
wounds.
Eagle keas living near the sea, visit after storm coasts and eat there dead
sea animals cast ashore.
As against to predatory birds of order Falconiformes prevailed in Holocene,
eagle keas are rather sociable birds tolerantly concerning to neighbours. During
feeding birds keep priority: birds preyed catch eat it first, and only after
them other neighbours flied to the feast, eat up rests. The priority is strictly
observed: one of birds, owners of catch, drives off other ones while another
bird eats, then they vary roles. Such tactics of survival adjoining to altruism,
allows each bird to gorge much more often than if these parrots were intolerant
of neighbours. Hunting of each separately taken bird or pairs happens successful
only approximately in one case from five or six ones. But due to catch of neighbours
even the crippled and weakened bird has an opportunity to eat normally.
Attachment of birds to each other is so great, that, happens, pair does not
break up, even if one of birds receives serious traumas during hunting and can
not have normal life. The bird making pair with it, incurs duties on feeding
of the partner, and frequently all other hatch.
Ursine
cuscus (Ursiphalanger marsupialis)
Order: Diprotodontia (Diprotodontia)
Family: Phalangers, or Climbing marsupials (Phalangeridae)
Habitat: New Zealand, flatland and mountain forests of temperate climate.
Picture by Alexander Smyslov
In various places of the Neocene Earth it is possible to find
consequences of human activity. Certainly, these species, as well as its many
contemporaries, have left the trace in paleontologic annals of planet. But there
is also other trace: results of introducing of various plant and animal species
to other habitats where they did not meet and where could not get naturally
earlier. The fauna of some places has very seriously suffered from rash installation
of new species, especially fauna of the remote islands.
When the human species had disappeared from Earth face, species delivered by
it at all did not gather to die out after it. Simply evolution in those places
where unbidden visitors have got has gone by other way, rather than before.
In fauna of different places species have appeared which never would get there:
in Australia various species
of camels, in Europe the
descendant of raccoon similar
to bear have appeared, and isolated from all continents New Zealands only
due to activity of people had got ground mammal fauna.
One of the largest Neocenic New Zealand mammals is the marsupial of huge sizes,
the ursine cuscus. It is the descendant of fox brush-tailed cuscus (Trichosurus
vulpecula), the marsupial mammal, acclimatized in New Zealand approximately
in 1900.
The New Zealand ursine cuscus is a huge ground animal weighting up to 300 kgs.
It is one of the largest representatives of marsupials of Neocene epoch. The
constitution of animal is massive, vaguely similar to ground sloths Megatherium
of prehistoric epoch.
The ursine cuscus spends the most part of life on the ground. The tail of its
ancestors, wood cuscuses, was any time adapted for branch seizing at climbing,
but at the ursine cuscus the tail is strongly reduced: it is short and nonflexible.
During walking of animal it serves as the balance weight, counterbalancing the
body. In the basis of tail the fat necessary for maintenance of ability to live
of an animal is accumulating – in winter the ursine cuscus becomes languid and
slightly hibernates This animal clambers on trees seldomly and very clumsily,
preferring to food on the ground. Its hind legs are plantigrade; feet are wide,
covered with thick layer of cornificate skin: it permits to go easily both on
stones heated up by the sun and on ice. The ursine cuscus moves basically walking
on two legs but frequently lowers to all four paws, especially if it is feeding
on mountain slope.
Wool of animal is thick, grey with black “cross” on back: longitudinal black
strip from nape up to middle of tail, and black stain on hips adjoining to it.
Throat, chest and stomach are covered with yellowish-white fur, and on the end
of tail the black hair brush grows. Due to thick warm wool animal can normally
live in mountains where in spring and an autumn there are light frosts frequently.
At the ursine cuscus there is rather massive head with wide flat forehead. In
connection with nocturnal habit of life at it there are large eyes “shining”
in darkness as it is characteristic at cats. Pupils are vertical, iris of of
eyes is chartreuse. Ears are short and pointed. The ursine cuscus badly distinguishes
colors. But it perfectly sees in darkness, has good hearing and keen sense of
smell with which help correctly finds edible leaves and ripe fruits.
At this animal there are strong jaws, wide molars and large chewing muscles:
the significant part of its diet includes young bush sprouts, and also seeds
of grasses. Except for them the ursine cuscus eats roots and tubers of plants.
On forepaws of animal hooked claws serving for ground digging and defense against
predators grow. The thumb of forepaw is opposed to fingers – it is a heritage
of climbing ancestors appeared very useful, increasing dexterity of movements
at food getting. On thumb flat nail grows instead of claw.
The ursine cuscus has nocturnal habit of life hiding in bush thickets in the
afternoon. In the afternoon the animal is inactive, especially in hot weather.
At this time the ursine cuscus alternates feeding with the periods of short
deep dream. After day spending of animals there are traces of their activity
in bushes: broken off and picked branches, and also small holes in ground where
animals had slept. But at night animals leave shelter and wander in wood searching
for forage. They mark the route by odorous liquid from the special gland on
hip, sniff at marks left by other individuals. With the help of these marks
animals learn about health state and physiological condition of neighbours.
They do not avoid direct contacts to neighbours: neighbours treat peacefully
enough to each other, they are frequently feeding and have a day rest together.
The convinced singles among the ursine cuscuses are rarity. Usually ursine cuscuses
keep in groups of 3 - 4 adult animals, but structure of these groups is changeable:
in the same structure such groups exist maximally some days, and then they break
up - some animals leave it, other ones appear. Usually each animal migrates
on wide territory, but does not come out of its borders. Borders of the “inhabited
world” at different animals are not coinciding to each other.
During winter cold snap ursine cuscus becomes sluggish and temporarily loses
desire to travel. Having found suitable place in wood or among rocks, the animal
digs out to itself shelter like den, or expands available one. In this shelter
the animal makes a litter, and hibernates. It not true hibernation: in this
condition the body temperature of the ursine cuscus is reduced only to some
degrees, it periodically moves and wakes up for a little time. At the ursine
cuscuses living on plains and in woods of the north of New Zealand, winter lasts
not for long – sometimes only about two weeks. At the animals living in colder
areas, it can be tightened about two months.
Pairing at these animals occurs in an autumn, but the embryo stops in development
up to the beginning of winter. In winter the female gives rise up to 3 cubs.
The pouch at this species opens forward. Cubs get into it (at this time the
female rummages hibernation for a little, cleaning pouch before cub birth) and
start to suck milk. They develop about 15 weeks, reaching to this time of the
size of kitten. At this age the pouch becomes cramped for them, and they gradually
move on back of mother. Keeping by paws for its wool, young cuscuses gradually
start to learn the world and to accustom to adult life. Cubs try food eating
by mother, study to distinguish other neighbours; sometimes they even play.
At the age of about one year, at weight about 60 kg, they begin independent
life. This is the most dangerous time for young growth: they not always can
expect for protection of adult animals if the predator will attack. Growing
up, young animals become capable to protect themselves. The main weapon of the
ursine cuscus is sharp claws on forepaws by which the animal inflicts deep wounds
to the aggressor.
At the age of four years, young animals can bear posterity.
Marsupial
pardus (Marsupardus aotearoae)
Order: Marsupials (Marsupialia)
Family: New Zealand predatory marsupials (Paradasyuridae)
Habitat: New Zealand, forests and woodlands, shrubs.
Picture by TS-cat
In the human era, the mammals of New Zealand were represented
by only some species of bats and by aquatic forms, pinnipeds. Fossils indicate
that the most primitive representatives of the mammalian classus have been preserved
in New Zealand for the longest time. The poverty of the native mammalian fauna
is evidence of the prolonged isolation of the archipelago.
In the human era, everything has changed. People deliberately introduced to
the islands a variety of mammals – ungulates, predators and rodents that could
not reach these islands in natural way. Among the new settlers in New Zealand
there was a representative of marsupials – the brushtail possum (Trichosurus
vulpecula). After its settlement in a new place, the ecology of this species
has changed, and it has become a dangerous animal for the local fauna: this
marsupial has switched from a plant-based diet to feeding on bird eggs and chicks.
In the Neocene, the descendants of brushtail possum diverged into several phylogenetic
lineages differing in ecology from each other. One of them led to the appearance
of the ursine cuscus – a large ground-dwelling herbivore. Another branch, being
adapted to predation, formed one of the largest New Zealand predators in the
Neocene – the marsupial pardus. It is very different in anatomy and ecology
from other descendants of brushtail possum and forms its own family of carnivorous
mammals.
The marsupial pardus looks very similar to cats and, but differs from them in
a heavier constitution. This animal is larger than a leopard – an adult marsupial
pardus weighs up to 200 kilograms. It resembles extinct prehistoric marsupial
lions (Thylacoleo) from Australia significantly more than felids. Marsupial
pardus has a large head, relatively short paws with sharp claws, a flexible
body and a long bushy tail. Like marsupial lions, the marsupial pardus has large
incisors, with which this predator deals a fatal blow to prey. The animal has
a short muzzle, and the jaws can open wide. The animal’s ears are relatively
short and rounded, and the eyes are directed forward and provide acute stereoscopic
vision.
The fur of the marsupial leopard has a mottled pattern of a large number of
irregular brown spots scattered over the yellowish background. They are large
on the body, and smaller and sparser on the paws and head. There are white “eyebrows”
above the animal’s eyes.
Picture by TS-cat |
The paws of the marsupial pardus are relatively non-specialized
– due to it the animal can live equally successfully in various landscapes –
from shrubs and woodlands to mountains and dense forests. The front paws of
the animal are plantigrade, and the hind legs are semi-plantigrade: the animal
supports on the tips of its toes only when walking on flat terrain. The claws
of this beast are not retractable; with their help the marsupial pardus climbs
trees and rocks well. The tail at this time serves as a balancer. The fingers
of the beast are mobile; with their help the animal can dismember prey and even
bring pieces of food to its mouth.
Unlike the predatory marsupials of the Holocene epoch, the marsupial pardus
is distinguished by good intelligence. It is the result of competition with
placental predators introduced to New Zealand, and adaptation to hunting large
prey – ungulates and other local herbivores. Due to its size and strength, the
marsupial pardus can attack almost any herbivore in New Zealand – the huge ultradama
deer and the taurovis – the bull-like descendant of the domestic sheep. When
attacking prey, the marsupial pardus bites its prey in the neck or at the base
of the skull, biting through the vertebrae and trying to damage the spinal cord
and medulla oblongata. These animals often hunt in a group, and then an adult
taurovis can easily fall their prey.
This species lives in pairs, and in places where prey is especially abundant,
stable breeding groups are formed, persisting for several years in a row and
consisting of a male and two or three females. The male of this species is much
larger than the female – on average, an adult male weighs 40-50 kg more than
a female. A group of animals marks the territory with musky secretions from
glands located at the base of the tail. During conflicts with trespassers, these
animals utter a long, dull roar. During the mating season, the male claims the
territory and the females, uttering staccato screeching cries in the evenings
and in the first half of the night.
After a very short pregnancy, the female gives birth to 5-8 joes. The brooding
pouch of this species is well developed and opens back, but there are only four
nipples in it, so only those cubs survive, that managed to crawl into the pouch
the first. Gestation of offspring in the brooding pouch lasts about ten months,
and only in the late spring of the next year the cubs become developed enough
to move independently. As a rule, only two cubs survive until this time. The
female carries them on her back, but takes them off during the hunt and leaves
them in the shelter, returning for them later. The cub has a dark brown coloration,
on which a lighter pattern appears over time. At the age of one and a half years,
the young animal leaves the parental group and leads an independent life.
Young animals reach the size of an adult animal at the age of 4 years. At the
same time, they become sexually mature.
Tiny
shrew-like hedgehog (Microerinaceus minutissimus)
Order: Hedgehogs (Erinaceomorpha)
Family: Hedgehogs (Erinaceidae)
Habitat: New Zealand, woods in foothills.
Picture by Alexander Smyslov
From the beginning in New Zealand there were no small ground
mammals – islands were separated from the common body of southern supercontinent
Gondwana too early. Therefore in absence of competition one local New Zealand
bat, Mystacina tuberculata, which had adapted to partly terrestrial habit of
life, replaced them. Introducing of mammals by people had radically changed
the situation and had changed the direction of evolution of local species of
animals. Among the introduced species of mammals there were hoofed mammals,
predators and marsupials. From the group of insectivorous mammals the European
hedgehog had got to islands. It had easily accustomed in new place of inhabiting,
and its descendants had equally easily outlived humans.
The Neocenic descendant of hedgehog, tiny shrew-like hedgehog has occupied the
ecological niche of small insectivorous animals, finally having superseded bats
from it. This creature is the tiny mammal similar to shrew in size and habits.
At it needles characteristic for hedgehogs are reduced and have remained only
on head, and grow as the longitudinal strip on back. It is connected to change
of way of life: the former sluggish creature has turned in fast small mammal
scurrying among bushes and grasses; speed has replaced to it passive protection
with the help of needles. But in behaviour of shrew-like hedgehog nevertheless
there are the features inherited from an ancestor and connected with ability
to be self-protected by means of needles. Tiny shrew-like hedgehog is rather
aggressive, despite of small size. At the attack of predator even if it is much
larger than this mammal, shrew-like hedgehog is protected actively. It bites
the enemy by peaked needle-like teeth, runs into it and tries to strike bristling
needles growing on head.
Shrew-like hedgehog is colored very contrastly. Its needles are colored white,
and wool on body is black – it is warning colouring which is perceived even
by animals lack of color sight. Being protected from the enemy, the animal utters
shrill peep (almost ultrasound) which is not loved by many animals with keen
hearing. Therefore birds and mammals usually avoid attacking tiny shrew-like
hedgehog, and kill it casually in small amount. One of main enemies of this
animal is large New Zealand mouse-eating
gekko, the large lizard living in wood litter and hunting from ambush.
Tiny shrew-like hedgehog is solitary territorial species. The individual site
is carefully marked by musk substance which is secreting from glands located
near the anal aperture. This animal is active in twilight and at night though
separate animals hunt in the afternoon, especially in shady cool woods. Males
and not sexual matured females do not arrange constant shelters and spend day
in temporary refuges. Only the pregnant female arranges a constant nest in bush:
she digs out a hole up to half meter deep, or occupies another's one. The entrance
in hole is disguised and protected by branches.
Occasionally shrew-like hedgehogs get in holes of castle
rabbits – herbivorous animals, settling in big colonies. In holes these
small mammals eat various insects, and sometimes attack newborn rabbit cubs.
But such cases are casual, and take place only in weak colonies, where there
are few adult animals.
This animal is carnivorous, and also eats only insects and other small invertebrates.
Shrew-like hedgehog has inherited from ancestor exclusive resistance to poisons;
therefore it frequently attacks even on poisonous centipeds and eats them without
harm for itself. It bites such dangerous animals in head to kill on the spot.
Frequently shrew-like hedgehog attacks lizards twice heavier, rather than itself.
In this case it carries off catch in bushes (despite of small size, it is very
strong) and stays near the catch, yet will to have eaten it completely. Rate
of metabolism at tiny warm-blooded animal is very high; therefore shrew-like
hedgehog is compelled to eat almost constantly, with small breaks on. For day
it eats the amount of food one and half times more, than it weighs.
This animal lives a little and very quickly. The female matures at the age of
about two months. After pregnancy, which lasts about 12 days, she gives rise
to 5 – 8 tiny, blind, helpless cubs. They completely develop at fortnight age,
and three-week old mammals already lead independent life. Bringing up posterity,
the female is strongly exhausted. In one month after the posterity has abandoned
the female, she restores the physical condition and is ready to pairing again.

A related species, mountain shrew-like hedgehog (Microerinaceus montanophilus), lives in mountains of New Zealand. It is larger (rat-sized) and more aggressive species of mammals. Needles on its head are reduced, but on back there is a crest of firm cross-striped needles. At danger it rears needles and stirs them up, turning to the opponent sideways. This species also leads solitary way of life and is a predator. It frequently attacks lizards and small mammals.
Taranga
(Taranga partenogenetica)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)
Habitat: New Zealand, woods of southern part of archipelago and mountain
areas of islands.
Picture by Carlos Pizcueta (Electreel)
Before people colonization and the introducing of various
species of animals the nature of New Zealand was the most original and ancient
by origin one in the world. New Zealand is the archipelago isolated from continents
since Mesozoic era; therefore the majority of animal groups, characteristic
for other areas of the Earth, simply could not settle it. Before people occurrence
mammals of New Zealand were presented only by bats and seals. Humans had introduced
numerous mammals to islands – predators and hoofed mammals which had changed
a nature of this isolated world up to unrecognizability. Native species of birds,
reptiles and invertebrates hardly resisted to the impact of introduced species,
and the majority of them had disappeared in human epoch or during some tens
thousand years after people disappearance. Descendants of introduced species
occupied ecological niches had been empty earlier, superseded New Zealand endemic
species and after millions years had generated the balanced ecosystem. Primary
it had been no digging mammals at New Zealand, but in Neocene one of introduced
species evolved to true underground inhabitant.
One of the most successful and nocuous for native fauna introduced species was
hermin (Mustela erminea). In human epoch this mammal became the reason of reduction
of number and disappearance of numerous species of New Zealandian birds. But
time of its prosperity had approached to the end in glacial epoch, when the
climate had changed. Ecosystems of the past degraded, and inhabitants of islands
should search for new sources of forage to survive. One of descendants of hermin
had turned to digging animal, having replaced moles absent at these islands.
Taranga – the new species of digging mammals – had appeared so in New Zealand.
In myths of New Zealand Taranga is the female, in the afternoon leaving the
land for the underground world. This animal, as against the mythical prototype,
had gone under the ground for ever, becoming the species deeply specialized
to underground habit of life.
Body length of taranga is about 20 cm, from which about a quarter falls to a
tail. The body of this small mammal is covered with rich velvety wool of grey
color. Populations from mountain areas differ in longer and denser fur. Head
of this mammal is very short and flat; on nose bridge the wide corneous scute
is advanced. Taranga digs holes with the help of forepaws. They are similar
to paws of the mole: short, wide, strong, with palms turned back and long thick
claws. The body of taranga is lengthened, hinder legs are rather weak – animal
pushes by them from walls of hole during the movement.
The skeleton of this mammal is additionally strengthened: it is important for
underground habit of life when the animal is threatened constantly with danger
to appear filled up with stones. Cranial bones of taranga are very thick; ribs
are expanded and strong. Vertebrae are strengthened by numerous additional shoots
and jags forming additional mechanical coupling. By structure of backbone this
animal is convergently similar to girder-backed shrew (Scutisorex somereni)
from Uganda lived in Holocene epoch.
Sense organs at taranga are advanced differently, rather than at hermin. Eyes
of animal are very small; sight sence is substantially degenerated: the animal
badly distinguishes contours of objects and does not distinguish color at all.
Sight is useless at life under the ground, and by importance for animal it had
been completely replaced with well advanced sense of smell.
Sharp thin teeth specify that taranga is active predator. This animal eats rodents,
worms and reptiles creeping in its holes.
Taranga does not like stony soils and lives in soft wood ground rich in humus.
Separate populations of taranga exist in mountain areas of New Zealand, but
they are settled in places where there are woods with thick layer of ground.
Also taranga does not live in tropical woods of the north of New Zealand, where
the layer of ground is rather thin.
This is the solitary animal. Each individual digs system of holes and marks
borders of territory with musk secretions. If two animals meet in the common
system of holes, there is a fight between them, frequently ending by the death
of one of animals. For these animals the cannibalism is characteristic, especially
at the lack of food.
Only the female ready to pairing can admit the male to the territory, but right
after pairings she banishes him. At this species of mammals the number of unique
features of breeding is developed. The hermin – the ancestor of taranga – strongly
depended on number of rodents, and at it the special adaptation permitted to
restore quickly the number of species had developed. The male of this species
had coupled to newborn females, and they grew, being pregnant. At taranga this
adaptation had undergone change in connection with warming in early Neocene
and rather constant conditions of inhabiting. This animal is able to parthenogenesis:
young females grow, and at them the new parthenogenetic generation of cubs already
develops. All newborn individuals of parthenogenetic generation are females.
If the female ready to pairing has not met the male, at her the occurrence of
parthenogenetic pack is also possible. In ovocites there is the doubling of
chromosomal complement which is not accompanying with cell division, and from
them normal cubs develop. In mountain valleys there are the populations of taranga
including only females – possible, this is the parthenogenetic posterity of
the single foundress individual. Taranga breeds two times per year; in litter
it may be 4 – 5 cubs.
This animal grows quickly, reaching the maturity at the age of half-year. But
the life expectancy of taranga exceeds five years seldom.
Taranga is not unique species of underground predators on Neocenic Earth. At
the territory of Europe the blindweasel lives –
it is another species of underground mustelid, completely lost sight sence,
but not adapted to burrow digging.
New
Zealand ultradama (Ultradama megaloceros)
Order: Artiodactys (Artiodactyla)
Family: Deer (Cervidae)
Habitat: New Zealand, South Island; woodlands, shrubs in temperate and subtropical
climates.
Picture by Alexander Smyslov
The fauna of New Zealand before the advent of human epoch was
the oldest and most distinctive fauna on Earth, with a high percentage of high-level
endemic animal groups. But during the human epoch this peculiarity was violated.
Man has exterminated many species of New Zealand endemics and introduced a large
variety of animals to the islands. As a result, by the end of the human era,
the fauna of New Zealand represented a bizarre mixture of wild and domestic
animals from different parts of the world, with the addition of single descendants
of the original indigenous fauna.
Among the animals introduced to the islands were deer of various species, including
the fallow deer (Cervus (Dama) dama). In their homeland, in the subtropical
regions of Asia, fallow deer and many other deer became extinct due to strong
anthropogenic pressure and habitat destruction, but in New Zealand they managed
to survive, despite systematic operations to reduce their numbers. In the process
of evolution, one of the descendants of the fallow deer turned into an animal
of impressive size - the New Zealand ultradama.
Ultradama lives in woodlands and mountain valleys, preferring areas of subtropical
climate, close to temperate. This animal is a descendant of large deer species
that appeared in New Zealand during the Ice Age at the turn of the Holocene
and Neocene. Ultradama has retained the large size characteristic of its ancestors:
the growth of this species at the withers reaches 170 cm, and its weight exceeds
400 kilograms. Males of this species are much larger than females (the weight
of the female is approximately 2/3 of the weight of the male). Despite its massiveness,
the ultradama retains the appearance characteristic of deer. The animal's coat
has a reddish-brown color, and sexual dimorphism is clearly expressed in its
color: female ultradamаs retain the spotty color characteristic of cubs throughout
their lives. Males, on the other hand, have a single color without spots, and
a brown mane develops on the sides and front of the neck.
Another feature of sexual dimorphism is the development of horns. Females of
ultradama are hornless, and in males the horns reach an extreme stage of development.
The ultradama is characterized by a huge span of horns - up to 250 cm; in this
way, this species of deer is only slightly inferior to the extinct Irish elk
Megaloceras. The horns of an adult male ultradama weigh about 100 kilograms,
and this significantly reduces the speed of his running. In the highlands of
New Zealand, fast-footed predators are rare, so males can be slow and heavy
- for gene transfer, it is much more important to be attractive to females.
The horns of the ultradama have a peculiar shape - the thick cylindrical base
of the horn smoothly turns into a flat polygonal “palm” (like the horns of an
elk), on which up to five - six long and almost straight processes, directed
to the sides and slightly upward, develop. Another process departs from the
front edge of the base of the horn - straight, directed forward and slightly
to the side.
The horn of the ultradama develops to this state over many seasons. The first
horns of a young male, growing at the age of one year, are straight, subulate,
about 50 cm long. In the second year of life, the horn branches out - a short
lateral process appears, and the “palm” of the horn slightly expands. In the
third year, the lateral process is already well expressed, and on the “palm”
there are short rudiments of the horns, which increase in length every year.
The horns of the male ultradama reach full development in the eighth year of
the animal's life.
Ultradama females and males choose different habitats for life: females and
young males (up to about two years of age) can live in a relatively dense forest,
where it is difficult for the male to move because of the large horns. Males
live in open woodlands and among bushes, where there are no obstacles to movement.
Possessing a powerful constitution, they easily lay paths among the bushes and
young forest stands along which a herd of such animals moves. Closer to the
breeding season, animals form mixed herds, which are divided into a number of
harems during the mating season. Antlers bring some inconvenience to males in
life: often males of ultradamаs drown in swamps, as in the Pleistocene male
big-horned deer drowned. But the decrease from accidents does not affect the
reproduction of these animals - during the breeding season, males with huge
horns gather the largest harem.
Ultradama feeds mainly on the leaves of shrubs and low-growing trees, and also
bites the tops of tall grasses. Due to such a diet, the teeth of the animal
are relatively weak, and the jaws are long.
Outside the breeding season, having shed their horns or having soft, incompletely
formed horns, ultradama males are non-aggressive towards each other. They keep
in herds of 10-15 individuals, feed and rest together. Calcium is vital for
them to form horns, so males seek out and regularly visit limestone outcrops.
In these places, they eat the soil and lick the limestone crumbling under the
roots of plants. In autumn (in the southern hemisphere - in April) the horns
of males complete development and ossify. Dead skin peels off them, and the
males clean the horns, butting the tree trunks. And later, by the beginning
of May, mating tournaments begin. Males roar trumpetly, challenging their rivals.
The duel of males is very ritualized. Huge animals converge with each other,
cling to the horns of the enemy, and wage a power struggle. Each male tries
to pry off the opponent's horns with his horns from below and raise his head
from the ground with the effort of powerful neck muscles. The defeated male
retreats, and the winner emits a victorious roar. There can be up to fifteen
females in the winner's harem.
The female gives birth to two cubs with a spotted camouflage coloration. In
the first weeks of life, they gradually try to eat grass, although they feed
on milk up to four months of age. Young animals become completely independent
at the age of six months. Sexual maturity of males occurs at the age of four
years, and females give birth to offspring already at the age of three.

New
Zealand orovis (Orovis austro-alpinus)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)
Habitat: mountains of New Zealand from wood zone up to Alpine meadows.
Picture by Alexander Smyslov
New Zealand during millions years had remained “the lost world”
even more forgotten rather than South America of Paleogene and Neogene epochs.
There were no even mammal species there except for pinnipeds for which ocean
open spaces are not a barrier and bats have arrived to these islands by air.
People have thoughtlessly “enriched” unique fauna of islands with various species
of domestic and exotic mammal and birds. Thus catastrophic damage was put to
local fauna.
After human disappearance on Earth New Zealand has remained in any measure to
the “lost world” condition separated from other world by Pacific Ocean. Animals
belonging to groups dyed out or fairly degrading in “big world” had kept here.
So, when number of hoofed mammals on continents had reduced, in New Zealand
one of their species had roughly evolved. Pacific Ocean by its heat had kept
this ground from congelation and has provided enough precipitations for grass
and trees developing on these islands. And in Neocene descendants of one of
survived species, domestic sheep, wander among meadows and woods. There are
swift-footed wood animals, massive inhabitants of plains and light forests,
and also dexterous and mobile inhabitants of mountains among them.
New Zealand orovis (literally: “mountain sheep”) has returned to habitat where
distant ancestors of these animals lived: in mountains. Here, on Alpine meadows,
small herds of these animals under the leading of dominant male graze.
Orovis is medium-sized animal (domestic goat-sized one). Back legs at it are
longer than front ones: it is a characteristic feature of mountain animals.
At such constitution it is more convenient to graze on slope.
Neck of animal is strong especially at the adult male - animals establish hierarchy
butting. Horns are short, straight, with thick bases, sticking up back and in
sides. Forehead is very wide, at the male it sometimes acts as osseous “helmet”.
Muzzle of orovis is narrow and rather long: it helps to nibble grass growing
between stones.
Hoofs of orovis are strong and wide. The bottom surface of hoofs is concave
and edges are rather sharp: with the help of such hoofs animal can walk on abrupt
slopes and keep on smooth rocks.
In mountains it happens coldly enough even in warm climate of Neocene. Therefore
orovises differ in dense and thick wool. Adult animals have grey wool on the
body, dark legs and “belt” (longitudal stripe) on back. For recognition of neighbours
on cheeks of adult animals there are white stains varying by size and form at
different individuals. In summer animals fade and wool becomes shorter and thiner.
Summer is time when air rings from flights of different blood-sucking flies.
Therefore tail of orovis had turned to excellent fly-beater – it is long and
flexible with brush of long hair on the tip.
Orovises migrate in herds in mountains of New Zealand. In each herd there are
large dominant male (large head with thick horns distinguishes it), females
standing lower in hierarchy (in harem of one male there are about ten ones of
them) and cubs. In summer these animals rise highly in mountains, and at times
they reach snow-line. Their basic food is grassy plants and mainly graminoids.
It is much more difficult to search for forage in winter – orovises hardly rake
snow with their thin legs. Therefore more often in winter it is possible to
meet orovises in foothills where snow layer is not so thick or it does not fall
absolutely. Animals feed in woods, graze grass and ferns, and gnaw branches
of bushes and young trees. At this time some harems of different males can unite:
in winter these animals tolerantly concern to each other. Also it is easier
to big herd to protect from local predators.
In spring when snow in mountains thaws orovises come back in mountains. At this
time between males there are fierce duels for females and territory: opponents
ram foreheads and make force struggle trying to tumble the contender down. Both
contenders loudly roar during a duel trying to make an impression upon the opponent.
Sometimes in the heat of struggle they rear and start to beat opponent by forelimbs.
After such duel defeated one runs out from stadium but sometimes at worst it
stays on a battlefield lying having had neck fracture.
The winner male drives “harem” of defeated one to the herd and marks new territory
by dung heaps. The defeated male now stays practically without means of subsistence:
it lives at the edge of territory which once was its property and carefully
hides the stay on it – up to the following breeding season.
Once a year in early spring while animals stay in forest zone, the orovis female
gives rise to two cubs. They can run in some hours after birth. When snow in
mountains thaws the herd goes to Alpine meadows and during the migration cubs
master elements of mountaneering. They suck milk up to 4-month age but since
the second week of life start to try plants eating by adult animals. Grown to
the age of half-year young males start to suit duels and to establish hierarchy.
At this time dominant male starts to show them the superiority compelling them
to leave from herd.
Young males form independent herds and migrate in mountains within two years.
Having reached maturity they start to challenge adult owners of “harems”, and
at times the herd of old male appears shared between two or three young applicants.
Taurovis
(Taurovis aotearoae)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)
Habitat: marshy plains and bushes of New Zealand in temperate climate zone.

Up to time of European colonization of New Zealand first settlers
of these islands had already time to destroy huge wingless moa birds occupying
ecological niches of herbivorous mammals. Ecological niches which have become
empty as a result of unlimited hunting of aborigenes stood empty rather not
for long time: after disappearance of humans their satellites – become wild
pets – have occupied them. Descendants of domestic sheeps, fertile and quickly
adapting animals have occupied niches of herbivores in various places. One of
sheep descendants had turned to very remarkable animal resembling bulls by mighty
constitution.
Taurovis, the “bull-sheep” – it is the name of this creature. This is very large
animal, largest one among New Zealand herbivores: its height at a shoulder is
up to 1.7 m at length of body up to 3,5 m. At it there are massive body, rather
short thick legs and large head. The neck of animal is short and covered with
mane of long hair. The body is covered with short brown wool with dark “glasses”
around of eyes and “stockings” on legs. At males wool on trunk is darker than
at females.
The “ram surface” of head of the mature male is trapezoid, flat, formed by forehead
and wide bases of short thick horns and covered with hairless cornificate skin.
Ends of horns are directed to sides and even a little downwards. Horns serve
to these animals rather for demonstration than for direct purpose: it is impossible
to make force struggle by them, at butting horns of animals do not adjoin at
all. At taurovis females horns are underdeveloped, and look as bone lumps on
each side of skull and forehead is more convex than at males. Edges of forehead
hang above eyes forming original osseous “peaks” protecting eyes from casual
damages by branches of bushes.
Taurovises live on bush plains of New Zealand frequently coming to bogs. For
walking across fenny bogs this animal has special adaptation: hoofs are wide
and can move apart increasing the area of support. Besides these animals perfectly
swim and frequently feed in rivers thining out thickets of reed and other marsh
plants. In heat animals spend all day in the river grazing on bank in the evening.
Near rivers one trouble waits of these large animals: in water mosquitoes, midges
and other blood-sucking insects breed in plenty. They attack warm-blooded animals
by large swarms exhausting them by stings. Taurovises are able to resist to
this mistfortune: they bathe in river or wallow in dirt. The drying up dirt
unpleasantly smells partly masking smell of animals. Besides it sticks wool
of animals to the true armour impenetrable for stings of mosquitoes.
In places where taurovises regularly feed bushes do not form continuous cover:
big animals trample and constantly renew tracks along which they walk. It expands
their forage base: among bushes clearings appear where graminoids and other
various grasses giving food to taurovises and other local herbivores plentifully
grow.
Taurovises live in herds including one male, some females and cubs of first
two years of life. Each herd has the territory which borders are marked by manure
heaps. These heaps are regularly renewed, and at times reach 1 meter height.
Herd has some basic routes of movement on territory. Within one year they are
used with different frequency: in summer animals spend time near to rivers or
lakes, and in winter more often in bush thickets.
Once a year female gives rise to one large cub. At three – four hours after
birth it stands and tries to walk, and for the second day of life it freely
walks behind herd. Young growth is covered with more light wool than adult animals:
it is straw-coloured with brown legs. Young taurovis spends first two years
of life in parental herd. But when it grows up and colouring of wool becomes
all more similar to adult one, young animal is compelled to abandon herd – adult
animals show aggression to young ones seeing competitors in them.
Young females give rise to posterity since four-year-old age.
