TO SURVIVE THE WINTER, ANIMALS NEED FOOD, WATER AND SHELTER.

WHAT DO ANIMALS DO DURING THE WINTER?

1) Some animals will HIBERNATE, hide and sleep during the winter months.

2) Some animals will MIGRATE, they will travel to warmer places for the winter months.

3) Some animals will ADAPT to their surroundings using different strategies (for example, they will grow a thicker coat)

HIBERNATION

espace

Hibernation is different from sleep. With normal sleep, the animal moves a little, has an active brain, and can wake up very quickly.


A "true" hibernator appears to be dead because:

- its heart rate slows down

- its breathing slows down

- its body temperature drops to almost the same temperature as the outside

- it takes a long time for the animal to wake up and to move about

espace


In late summer and fall (autumn), before going into hibernation, animals eat a lot of food. Their bodies are able to live off the stored body fat. They look for a safe place to spend the winter: caves, dens, burrows . .

Some animals are not "true" hibernators. During hibernation they wake up and move around, have a snack and then go back to hibernation again. We call them dormant animals.

espace

-> Look up examples of animals that hibernate on the following web page:

Animals in Winter - Hibernation (here you can also find information on bears, which are not "true" hibernators)

espace

-> Find out about "not true" hibernators, animals that sleep and eat during the winter, on the web page:

MIGRATION

espace

Animals "migrate" or travel to warmer places where they can find food, shelter and water.

OTHER WAYS OF ADAPTING TO WINTER

espace

Some animas will adapt to their surroundings by growing a thicker, warmer coat.

The coats of some animals change colour for the winter so they can hide better from predators: they change their coat's colour from brown to white so they cannot be seen in the snow.

Read what happens on the following web page:

Animals in Winter Coats

space

Some birds are able to live in cold conditions during the winter, they do not migrate.
