How pigeon use magnetic compass for navigation?

Pigeons use a magnetic compass for navigation by detecting Earth's magnetic field through specialized receptors in their eyes and brain. These receptors contain magnetite, which allows them to sense the direction and intensity of magnetic fields. This ability helps them determine their position and orientation during long-distance flights, enabling them to navigate accurately even over vast distances and unfamiliar terrains. Additionally, they often combine this magnetic information with visual landmarks and their innate sense of direction.
