Birds know where to migrate through a combination of instinctual behaviors and environmental cues. They are born with the knowledge of when to migrate and the general direction. Additionally, they use the sun, stars, Earth’s magnetic field, and landmarks to navigate their way to their destination. Changes in daylight length and temperature also signal birds when it’s time to migrate.
