One of the most mysterious things in nature is the ability of certain creatures to find their way home sometimes from great distances. Birds are not the only ones who can do this. Bees, eels and salmon are able to return to a particular place after long journeys too.
Most migrations take place between breeding grounds and regions where animals feed. For some animals, such as the lemming, the move is a one-way trip. Some scientists call this movement emigration, because these animals never return to their homes. For other animals, such as birds, the migration includes a return trip home. Birds move in periodic migrations, or at regular times during
their lives, and often to the same place year after year.
