How Do Animals Migrate Across the World?

Animals go on big trips to find food or better places to live. Some use the sun, stars, or even smells to know where they're going. Like a bird flying thousands of miles from one continent to another, it's like having a map in its head!

Examples

A bird flies from the North to the South every year because it knows where the warm places are. It follows the stars like a map in the sky.
A turtle swims across an ocean to find a place where it can lay its eggs. It uses the Earth’s magnetic field as a guide.
A wildebeest runs for miles through the savanna to reach fresh grass. It follows other animals and remembers the way back from last year.
