Like many other animals, swallows will fly south when the days turn cold and the leaves from trees begin to fall. They travel many miles to find a warm winter. This kind of travel is called migration. Birds are animals that like to migrate a lot when it is cold. They leave in autumn and come back during the warm spring months.
Many birds don't like the cold. They need food, but plants die and insects hide in winter. As a result, they will only come home the next year, when there will be plenty of food for them to eat.
But the trip is often hard and not safe. Many birds fly in groups and make noises. Cranes fly in groups like the letter V or in a row. Others travel in pairs or alone. Some can travel a very long way. They fly between lands.
How do the birds find their way back? They look at things like the sun, the moon and the stars. They never get lost!
