Every year birds, whales, fish, butterflies, turtles, geese, and deer migrate. They leave the cold northern parts of the country and walk, fly, or swim south. Then they return to their summer homes in the spring.
Some animals travel a long way every year.
Some butterflies fly all the way from New England to Mexico. Whales swim from Alaska to Hawaii. Some birds fly for weeks to get to their winter homes. They can follow the stars, watch the sun set in the west, and look for lakes and mountains. They can also find special smells, sounds, and foods along the way.
