Some animals migrate short distances while others travel thousands of miles. The tiny Arctic tern flies from the Arctic Circle to the Antarctic and back each year. Other animals migrate in huge numbers—100 million monarch butterflies swarm across North America to reach Southern California and Mexico. Animals migrate from one habitat to another for many reasons. Sometimes it’s the changing climate. It might be to find food or water. Often it is to find a safe place to breed or even to find a mate.
