Birds navigate with an internal magnetic compass
Migratory birds possess an internal magnetic compass, sensing Earth's invisible field to navigate vast distances, like a natural GPS guiding them across continents.
Many birds possess a built-in magnetic compass, allowing them to sense Earth's invisible geomagnetic field for incredible long-distance migrations. This amazing ability, called magnetoreception, acts like a natural GPS, guiding them across continents and oceans. Scientists believe birds might use specialized cells in their beaks or light-sensitive proteins in their eyes to detect these fields.
