Nature’s Babies
Mike Dilger


There are few things more endearing than baby animals, but their charm belies their struggle for survival. From frolicking foxes to boisterous bears, lounging lions to zealous zebras, Nature's Babies explores the lives of some of Nature's most engaging offspring and reveals the ingenious ways they cope with growing up.When it comes to 'bringing up baby', Nature has an infinite variety of approaches, from parents who lovingly tend to their young for years to newborn babes who rough it on their own from day one. Nature's Babies offers a rare insight into how young animals make it into this world and learn to fend for themselves.Accompanied by beautiful photography throughout, Mike Dilger takes us on a journey of discovery through the intriguing world of Nature's Babies.

INTRODUCTION (#ulink_473ab67e-2699-59f2-8c5c-59c9056556b0)


Nature’s Babies is an unashamed celebration of the fully technicoloured glory of the natural world itself. The seemingly infinite variety of different baby shapes and sizes is of course down to the cleverest and most powerful beast of them all: evolution. What else would have created babies that at one end of the spectrum are impossibly cute, yet at the other end would not look out of place in the most off-the-wall science fiction novels?

Parenting skills can vary enormously from the non-existent to the lavish. For some animals being born is a rude awakening into a harsh, unforgiving world with no parental care whatsoever – just ask leatherback turtle hatchlings as they have to run the gauntlet to sea!

This book showcases some of the weirdest and wonderful stories of the babies’ development, too. Who would have thought, for example, that a grey kangaroo’s baby is born no larger than a kidney bean, and from the moment it enters the world has the most daunting journey to complete even before it will be able to feed for the first time? And exactly why do Galápagos tortoises take an astonishingly long 25 years to reach maturity?

Whilst focusing on the babies, this book will hopefully also test our own notions of how we humans fit into the natural world. We think of our birth, babyhood and adolescence as normal, but how ‘normal’ compared to other animals are we? Whilst we perhaps arrogantly think of the human race as producing model babies and parental skills that are unsurpassed, do we in fact have something to learn from our wild cousins? After reading Nature’s Babies, you decide!




LITTLE GRIZZLIES (#ulink_47cc6822-07e1-5d60-9d90-18d310258465)


Found right across North America, Europe and Russia, with smaller pockets in Asia, the brown bear is both the most common and widespread of all eight bear species. The famed grizzly is the race of brown bear most commonly found in Alaska and Canada, so-called because its hair is lighter at the tip than at the base which gives this bear a ‘grizzled’ appearance.

The larger grizzlies can reach an impressive 700kg (1,500 lb) in weight, and with their massive shoulders, huge forearms and plate-sized paws, they must be one of the strongest animals in the world; their only predator is, of course, man and his gun. Ironically for an animal with such size and strength, the main diet of grizzlies tends to be roots and fungi, supplemented by fish and small mammals if and when available. Their incredible bulk is often used to drive wolves and cougars away from kills.

During times of plenty in the summer months, the female grizzly puts down huge reserves of fat which she relies on to get her through the winter. The breeding season also occurs in the summer, but the fertilized egg will not be implanted and begin to grow until the winter, when the female is tucked away asleep in her den, hidden away from the worst of the weather. The most common litter size is two; the blind, toothless and hairless cubs are born in the winter den and grow quickly on their mother’s milk, only emerging with their mother into the big, wide world when spring finally breaks.

Little grizzlies remain with their mother for two to four years, learning the ‘tricks of the trade’ which will prove essential if they are to grow up as big and strong as their parents.




LIKE A DUCK TO WATER (#ulink_c09cb2c0-798d-5b02-8562-298364df7001)


Unlike seals and dolphins, our smallest marine mammal has no blubber. This means that adult sea otters have to spend up to three hours a day grooming their fur meticulously to ensure that it stays in top condition and remains able to trap the vital insulating layer of air which keeps them warm.

When they are not busy grooming themselves, sea otters spend a large part of the day hunting for food. From depths of up to 40 m (131 ft) they retrieve clams and sea urchins from among the rich kelp forests on the sea floor and bring these up to the surface. The sea otter is an animal which likes to spend a large part of its life belly up, even when feeding. Lying on its back, it uses its underside as a table to crack open these tough shells with the help of a special stone which it retrieves from a ‘waistcoat pocket’ situated under its armpit.

Although the birth of the single pup takes place on shore, the mother immediately guides it straight into the water. Despite being born with its eyes open, and with a full set of milk-teeth and baby fur, the sea otter pup is initially very vulnerable to the cold, and so it spends the first four weeks of its life being groomed and fed on its mother’s belly. When the mother does have to leave her pup on the surface whilst diving for food, she often wraps her youngster up in kelp to prevent it drifting off. As the pup’s fur traps so much air, it bobs on the surface like a cork until its mother comes back to retrieve it!

A LEAP OF FAITH (#ulink_8ef763af-8075-5c2a-8205-fdce6fee7852)


With its torpedo-shaped body, long, narrow wings and its dagger-like bill, the gannet is a very lean and very mean fishing machine. It is also an incredibly sociable bird during the breeding season and nests in densely packed colonies on steep cliffs and raised slopes around the coasts and islands surrounding Britain, northern Europe and northeast America.

Gannets are usually faithful to both their partner and to their breeding location, and pairs of birds will often return to exactly the same tiny territory of guano-stained rock each year. This special area will be stoutly defended against all neighbours and any newcomers by ritualized displays between the pair. If trespassers don’t get the earlier, more subtle messages, they will receive a quick jab of the gannet’s sharp bill.

Once the single chick is hatched it is initially guarded around the clock by at least one parent to ensure that it is not snatched by any opportunistic gulls eager for an easy meal. As each adult returns from a fishing mission, the black, naked youngster reaches deep down into its parent’s mouth to feed on regurgitated fish. The youngster will grow quickly on this rich diet of mackerel or herring which it is brought by its conscientious parents several times a day. But then, at around 90 days, the parents suddenly stop feeding their offspring in an effort to force it to fledge. Egged on by hunger, the still flightless chick has to make a kamikaze-style jump down to the waters below before it can begin paddling south for the winter. Only once it has lost a bit of weight from such energetic paddling will it finally be able to take to the air and hunt for itself.

PRICKLY YOUNGSTERS (#ulink_b6cd123a-6c16-5977-a783-ace2ee90e9ea)


So-called for its fondness for hedgerows and because of a snout that resembles a pig, the hedgehog is very aptly named indeed. Setting aside its preferred habitat and nose, the hedgehog’s other most distinguishing feature is, of course, its prickly nature.

During the day hedgehogs will seek shelter in a nest of grass and leaves under bushes or logs until they take their cue from dusk to begin roaming through parks, neighbouring gardens and woods in their perennial search for earthworms, slugs and snails. To prevent themselves actually figuring on the menus of other larger predators such as badgers and foxes, they are famously capable of rolling into a thorny, impenetrable ball to protect their vulnerable undersides.

For obvious reasons, a male wishing to mate with a female has to do so very carefully, and not until she is absolutely ready! As hedgehogs hibernate during the winter, their noisy mating takes place during the summer months and just over a month later four to five youngsters are born. Fortunately for the mother, the baby hedgehogs are ‘spine-less’ at first, but only a few hours after birth the baby’s first set of nearly 150 spines will already have pushed up through the skin. By the twelfth day the youngsters have managed the art of curling up when necessary, and after a further month and a couple of sets of new spines later, the young hedgehogs become perfect miniature replicas of their prickly parents.

A hedgehog’s prickles, or spines, are actually hollow stiff hairs that can be raised at will if danger threatens.




THE LONGEST DROP (#ulink_f69909c4-2822-5096-a969-ce6899fe8e92)


It’s quite a boast to declare that one is the tallest of all land-living animals, and one which the giraffe is able to make without fear of contradiction. Over thousands of years giraffes have gradually evolved from their shorter-necked ancestors so that today the largest males can reach the dizzying height of 5 m (16 ft) – to the very tips of their horns! The giraffe’s height enables it to browse its favourite food of spiny acacia leaves at levels higher than all the other herbivores are capable of reaching.

In addition to an impressive neck, which incidentally only contains the same number of bones as a human neck (seven), the giraffe possesses long, elegant legs which can produce impressive bursts of speed when necessary and also keep hungry lions at bay with powerful kicks.

Female giraffes associate in small groups whilst the males live either in ‘bachelor’ herds or on their own. The older and larger males tend to mate most of the females in the herd after seeing off any competition through a series of jousts where necks and heads are frequently swung like a wrecking ball-and-chain to assert dominance. The gestation period of the giraffe is long and can last up to 15 months, and the mother gives birth to the single calf standing up. This means that the newborn calf’s entry into the world entails it landing with a terrific thud on the ground below. Within just a few hours the world’s tallest baby is capable of following its mother. This is absolutely essential; there are so many predators on the prowl that the youngster really does have to hit the ground running!

Even the world’s tallest baby has to look up to its mother!




HATCHED IN A HUDDLE (#ulink_861fd407-af53-5580-8537-1c3b0cdd4329)


Not only is the Emperor penguin content with being the tallest and heaviest of all living penguins, but it is also the only species tough – or crazy – enough to breed during the Antarctic winter – surely the most challenging environment on earth in which to raise a family.

When temperatures drop to below -40 °C (-40 °F) and polar winds gust at over 190 km/h (120 mph), the only way that these penguins are able to survive during the breeding season is by being very sociable: they crowd together in large groups and thus protect themselves from the elements. These huddles move constantly so that the birds along the colder edge can eventually shuffle into the middle of the group, thereby temporarily exchanging places with the warmer birds in the centre, who must then take their turn on the chilly periphery.

Emperor penguins stay faithful to their mate each breeding season. After an elaborate courtship, the female lays a single, thick-shelled egg, which is then carefully deposited onto the feet of the male to incubate in a special pouch. She then promptly deserts him for two months to feed out at sea. Together with his fellow abandoned males, the male fasts for the entire 65 days of incubation, until the female arrives back to feed the newly-hatched chick on a rich diet of regurgitated fish, krill and squid. It is only then that the half-starved males are allowed to leave and feed out at sea.

To begin with the young chicks are not well insulated and so they must stay sheltered in their mother’s brood pouch for at least 50 days before they join crèches with other youngsters. Here they keep warm by huddling and learning the skills that they will eventually need to survive as breeding adults.

BRINGING UP BABY (#ulink_4ed5e624-129e-593b-8af6-5fb839dce13e)


This largest of all living land animals really needs no introduction. With a huge set of ears, a long pair of tusks and a versatile trunk, the African bush elephant is probably the best known and the biggest of all three species of elephant and is also undisputed master of the African savanna.

Female African elephants spend their whole lives in social groups. These consist of the dominant female (matriarch), and an array of immediate family members including mothers, daughters, sisters and aunts. Adult males, on the other hand, lead either solitary lives, or live in loose ‘bachelor’ herds and only join the female unit when one of the herd is sexually receptive. Females ready to mate will seek out the biggest, strongest and oldest bull elephants: these will be the ones who have already asserted their prowess by fighting with and driving away any other potential suitors.

The elephant’s pregnancy is the longest in the natural world and lasts 22 months. At the end of this gestation period, the mother gives birth to a calf weighing up to 120kg (264 lb). The young elephant is born with very few survival instincts and must therefore rely on its elders to teach it everything it needs to know during a prolonged upbringing. All members of the tight-knit female group participate in the care and protection of the newborn calf and it quickly becomes the centre of attention. Since everyone is related, there is never a shortage of babysitters on hand to help, too!

Baby elephants are never short of willing playmates.




THE BIGGEST CLUTCH (#ulink_ae7b3437-d1fc-5f86-a1fe-68d806b895b8)


By choosing a flightless lifestyle, the ostrich has been able to increase its size and weight to such an extent that it is now the world’s largest and heaviest bird. These features, together with their tremendous eyesight, phenomenal running speed and a vicious kick, enable them to protect themselves on the predator-riddled plains of eastern and southern Africa.

In the wild, ostriches are nomadic and will travel long distances in mixed-sex herds with other grazing animals such as zebra and antelope to track down the seeds, plant matter and odd insect which make up their diet. As ostriches lack teeth, they swallow stones to help grind up these tough foodstuffs in their gizzard. Although their wings are not used in flight, they are still large with a wingspan of over 2 m (6 ft 6 in), and male ostriches use them in elaborate mating displays when they compete for territory, social status and the all-important attentions of a small harem of females, or hens.

Once the dominant male has successfully fought off the competition, he will then mate with all of his females. This often leads to many of the hens laying their eggs in the same communal nest, resulting in the production of a clutch of over 30 eggs. Weighing in at 1.5kg (3 lb 5 oz) each, the world’s heaviest eggs are then incubated by the dominant hen and the male until they hatch after about 40 days. The father’s responsibilities do not stop there, as he then assumes sole control of the crèche, in order to both defend the hatchlings and also teach them what to feed on and how to find it.

Until they are able to fend for and defend themselves, ostrich chicks will always stick to safety in numbers.




JUST A BIG BABY (#ulink_2fbd71a8-f406-57d9-a610-52402ff09da8)


Surely one of the most celebrated of all beasts among whale-watchers because of their ability to virtually leap clear of the water and their haunting songs, the humpbacks are also thought to carry out the longest migration of any mammal. Each year they will travel from their summer feeding areas in the higher latitudes to breed and give birth in tropical waters during the winter – a round trip of over 16,000 km (10,000 miles).

The humpback is found in all the major oceans and can reach an impressive 12 to 17 m (39 to 55 ft) in length. Their knobbly flippers are immensely long and can be used, together with the colour of the underside of the tail, to identify different individuals. Humpbacks only feed on krill and small shoaling fish in the summer, before living off their fat reserves during the breeding season. When feeding, they are capable of working cooperatively using a technique called ‘bubble-netting’: a number of whales will drive a shoal of fish into a tight cylinder of underwater bubbles, before piling in, mouth agape, to swallow – in just a few gulps! – thousands of fish filtered from the water by special baleen plates.

The male humpbacks are particularly vocal, and are capable of producing loud and complex ‘songs’ by forcing air through their nasal cavities. It is not understood if this is used by breeding males to try and intimidate other males or attract females, or even if it serves another function entirely. Groups of males will often compete for the females, and on their return to the tropics twelve months later, the females will give birth to a 5 m (16 ft) long, 700kg (1,500 lb) calf. The young calf will then be a constant shadow beside its mother until weaned a year later.
