It's the time of the year when the weather gets colder, days get shorter and snow covers the ground. But do you know, how do the animals survive through this?
Animals do many different and amazing things to get through the winter. Some of them "migrate." This means they travel to other places where the weather is warmer or they can find food.
Birds Migration-Do you know that birds can fly very long distances, but they mostly migrate to shorter distances. Birds seem to navigate like sailors once did, using the sun, moon and stars for direction. They also seem to have a compass in their brain for using the Earth's magnetic field.Animal Migration- There are a few mammals, like some bats, caribou, elk, and whales that travel in search of food each winter. Many fish migrate; they may swim or move into deeper, warmer water.
Insects Migration-Some butterflies and moths fly very long distances. Most migrating insects go much shorter distances. Many like termites and Japanese beetles, move downward into the soil. Earthworms also move down, some as far as six feet below the surface.
