SNOWY TUNDRA
How do Arctic animals make warm homes in the cold? Snow falls and fierce winds blow across this frozen land, called the polar tundra. Many animals build their homes under a blanket of snow or shelter out of the wind.
In the spring, all kinds of animals come out of their snowy dens. The weather is warmer, the days are longer, and a few shoots begin to show. It’s time to search for food and make nests for new babies.
On a hillside, an Arctic fox hides out of the wind in a burrow, or hole. The fox curls its tail around its body to keep warm. The Arctic fox’s coat changes color to blend in with its Arctic home. In winter, the coat is white as snow. In spring, it’s speckled like the rocky tundra.

Arctic fox Arctic hare
A female Arctic hare lines her stony shelter with moss and fur to make a cozy nest. Soon, she will give birth to a litter of up to eight baby hares, called leverets.
All winter long, a group of lemmings crowd into a burrow with tunnels. Above, a layer of snow keeps the warmth inside their home. The lemmings eat roots growing down from the surface. In the spring, the lemmings come aboveground to eat fresh buds and leaves. 6
Find the Arctic animals in their burrows, nests, and dens. LOOK INSIDE
A pair of eider ducks soar over the tundra. They’re looking for a safe place to make a nest, somewhere hidden from predators. The female lines the nest with soft, downy feathers from her chest. This will help to keep her newborn chicks warm.
An Arctic ground squirrel pops up from its underground home, where it spent all winter. Straightaway, it starts preparing for its sleep, or hibernation, next winter by fattening up on spring grasses and fruits.
A couple of snowy owls make a nest on the cold ground. They build out of the wind so snow won’t blow inside the nest. The female scrapes at the rocks, presses the nest with her body, and adds a layer of feathers. Then she sits on her eggs.
A wolverine walks away from her snowy den under a heap of large rocks. She has given birth to two babies, called kits. Now she’s hungry! Large paws, long claws, and sharp teeth help her to hunt hares and ground squirrels on the snowy plains. She takes some of this food back to the den and buries some to eat later.
Where are polar bears born?
In the middle of the Arctic winter, polar bear cubs are born in a cozy, sheltered den. It is biting cold outside. The newborns are tiny, toothless, and blind, with just a thin layer of fur. But the den is safe and warm. Here, the mother feeds her cubs until spring, when they will be big and strong enough to go outside in search of food.
EXTREME HEAT
How do animals make homes and keep cool in the hottest places?
Animals use ingenious ways to protect themselves from the burning sunshine.
For some animals, such as Indian harvester ants, jerboas or great desert skinks, it’s a huge task to build a cool home. So, they work as a team. But a fennec fox and a Mojave tortoise dig an underground burrow for themselves. A kangaroo has a unique way of protecting its young in the extreme heat.
Where is a baby kangaroo kept safe?
In the Australian outback, a kangaroo mum provides a snug home for her baby, called a joey. She keeps her joey safe in a pouch of skin on her belly. When the joey is born, it’s the size of a jellybean. The joey drinks milk from its mother’s pouch until it is big and strong enough to live by itself.
Why do Indian harvester ants build a round nest?
These ants have a clever way to keep themselves cool and dry. Above ground, they build spiralling mud walls to stop their nest from flooding during heavy monsoon rains. The nests are built on a slant and the spiralling channels guide the rainwater away. Underground, the ants build tunnels with cool, narrow passageways to protect themselves from the beating, hot sun.
How does a fennec fox use its furry feet to build its home?
In the Sahara Desert, a fennec fox uses its feet like shovels to dig a sandy, underground den. The fox’s feet are covered in thick fur and act like shoes so it can walk over the burning sand. The fox also has huge ears that give off heat and help to keep its body cool.
How does a tortoise avoid the heat of the desert?
A Mojave tortoise escapes the fierce heat of the sun in a cool underground burrow, where it spends most of its time. The tortoise is cold-blooded and so the same temperature as its surroundings. By sleeping through extremely hot periods in its underground burrow, the tortoise can survive on very little food.

Which animal has more than one underground home?
Jerboas live in hot deserts and steppes, or dry grassy plains. They dig themselves many homes with their feet and teeth. To keep cool in the summer, a female digs a burrow close to the surface, where she looks after her pups. To stay warm in the winter, the jerboa digs another burrow, deeper underground. A jerboa might also build an away-day burrow, where it stays when out hunting.
What do great desert skinks build together?
Great desert skinks are burrowing lizards that live in the Australian desert. They work together to dig a huge underground home. There are rooms for adults, sharing rooms for brothers and sisters, plus a separate room where all the skinks can go to the toilet.

BEAVERS’ LODGE
How do beavers construct a home?
Beavers gnaw down trees and branches on the riverbank, then swim with the logs to the middle of the river where they build their home. It is called a lodge.
First, the beavers prepare the construction site by building a high wall across the river. This is called a dam. It creates a safe pond in the river for their new home, which will have an underwater entrance and a dry room for all the family.
A family of up to eight beavers works together to build a dam and a lodge
Often, the beavers build at night.
Trip after trip, the beavers gather branches, stones and mud from the banks of the river and the river bed. They use this material to build a dam Eventually, the dam shows above the water’s surface.
Behind the dam, a deep pool forms. This is where the beavers will build their lodge on a private island. It will be far away from the riverbank and predators, such as bears, wolves and coyotes.
A beaver gnaws the base of a tree with its sharp front teeth, called incisors. Once it has chewed away enough of the trunk, it lets the wind blow the top section over.
As the beaver swims, the river helps it to carry the heavy logs. A beaver spends lots of time in the water swimming and building. It has a thick, waterproof coat of fur that keeps it warm and dry.
See-through eyelids help a beaver to see what it’s building underwater. It’s a bit like wearing goggles. A beaver can also close its nose and ears and stay underwater for up to 15 minutes.
The beavers build an underwater entrance straight into the dry part of the lodge.
It’s warm in the living chamber, where there are places for eating and sleeping. The beavers eat from an underwater store of food they collect in the autumn.
A beaver’s body is designed to swim fast. It can twist and turn in the water. A beaver also has a flat tail that works like a rudder and large webbed back feet that move up and down for speed.
The lodge is built on a dome-shaped foundation, so the lower parts of the lodge are wet and the higher part is dry
