Birds navigate during migration using a variety of methods, including:
Celestial Navigation: Birds use the sun, stars, and even the Earth's magnetic field to orient themselves and follow a specific route.
Landmarks: Some species of birds are able to recognize and use landmarks such as rivers, coastlines, and mountains to guide their migration.
Innate Knowledge: Many birds are born with an innate sense of direction and timing, allowing them to navigate without prior experience.
Following Others: Some birds follow more experienced individuals or flock leaders to reach their destination.
Environmental Cues: Birds can also use environmental cues such as wind patterns, temperature changes, and even smells to navigate during migration.
