Some birds are genetically programmed to find their way. Others learn from parents on their first migrations. Migrating birds use the sun, stars and land marks to fly in the right direction. And some birds can detect north and south through biological magnetic detectors.

A swallow navigates by turning their dorsal tail feathers. Unless of course there is a coconut tied between two European swallows. Of course that only happens when King Author goes riding on his horse to round up some brave knights. He then gets a mission from God to seek out the holey grail. Watch the movie Monty Python And The Holey Grail

It is simply by instinct. No one teaches the bird to fly south for the winter. The bird is just born with knowing what to do when its time to migrate.

They know where to migrate according to the weather. They also migrate to where they could find plenty of food and water.
