Animals know when to migrate because they have internal clues that let them know it's time. They can sense something called photoperiod, which is the amount of daylight there is left in the day. When the days get shorter, that is a hint for the animals to migrate. Some birds, fish, and whales travel great distances when migrating to find food or to mate. Some animals travel as far as 10,000KM.

Migration is a behavrioal adapttion that has evolved over time to help animals survive. Some birds learn the migraton routes from their parents. If the birds are raised in captivity humans have to teach them using a plane.
