When snow and ice cover the ground, it can be very hard for animals to live or find food during winter. However, some animals can get through this hard time in different ways. Migrating is a good way to avoid the cold for some animals. For example, birds and butterflies can fly to a place with nice weather; then, they fly back home in the spring. We call this migration. Another good way to avoid the cold is to hibernate or sleep through it. Many animals hide and sleep during the winter. Their bodies slow down, so they save their energy. They do not eat. They live off of their fat. They do this until food returns. We call this hibernation. Snakes, frogs, and bears hibernate. Some animals store food in their homes. They do not sleep all winter, but they do much less. They live on the foods they collected in the summer and fall. This is what squirrels, beavers, and raccoons do. Other animals tough it out. They do not leave. They do not hide. They must survive. Sometimes nature helps them out. These animals grow thicker coats or change the color in winder. The arctic fox is brown in the summer, but his coat turns white in the winter, for example. In conclusion, winter may be pretty. It is nice to see snow on the trees. But it is dangerous too.
