Cold, Snow, and Ice
In many parts of the

Animals that live in places where seasons
change have many adaptations to
survive winter. Adaptations include ways
animals look and how they act.

Winter Adaptations
How do animals survive winter?
Many animals migrate, or move
from one place to another. Animals
with wings may migrate in the
fall. Some herd animals, such as
caribou, also migrate.

Some animals hibernate. Many toads dig
down into the soil and go into what seems
like a long, deep sleep. Other hibernators
eat heavily in the fall to get fat.

Since they cannot eat while they
hibernate, they use energy from their body
fat to stay alive.

their homes living on stored food
and resting.

Active animals have other adaptations.
Some animals’ fur turns from brown
to white for the winter months. This
camouflage helps them blend in against
the snow.

Many active animals eat stored food or
grow thicker fur. Others, such as mice,
live in tunnels under the snow. Snow acts
like a blanket to help keep them warm.
