Ready for Winter
Winter can be very cold. Less food grows. Animals have to prepare for these changes. Here is how some animals get ready for winter.
Some animals migrate.
Many birds migrate. They go where it is warm for the winter. Monarch butterflies and gray whales also move to warmer places.
Some animals hibernate.
Hibernating is like sleeping. When animals hibernate, they are not very active. They do not need much food. Chipmunks and bats hibernate. So do bears.
Some animals take shelter.
Moles live underground. They tunnel deeper in winter. The soil does not freeze there. Opossums line their dens with leaves to keep warm.
Some animals grow new fur.
The fur of Arctic foxes turns white. White-tailed deer grow thicker coats for the cold.

Pets prepare for winter too. Some dog breeds grow a second coat for the cold. This is a husky. It sheds its undercoat for the summer.
