How Do Birds Migrate Across the World Without Getting Lost?

Birds travel long distances every year, just like you go from school to home and back again. They use clues from the sun, stars, and even the Earth’s magnetic field to find their way.

Birds have a kind of map inside their brains. When they fly, they look at where the sun is in the sky, it's like having a clock that tells them which direction to go. At night, some birds use stars, just like you might follow a path by looking up at the moon.

Some birds can even feel the Earth’s magnetic field, kind of like how a compass works. It's like they have a tiny magnet in their head that helps them know where they are, even when it's cloudy or dark.

All these clues help birds travel across oceans and continents without getting lost, just like you use landmarks to find your way home!
