Migratory birds navigate long distances using a variety of methods, including:

  1. Sun Compass: Birds can sense the position of the sun in the sky and use it as a compass to determine their direction of travel.

  2. Magnetic Compass: They are believed to have tiny magnetic particles in their brains that help them sense the Earth's magnetic field and navigate based on it.

  3. Landmarks: Birds use visual landmarks such as coastlines, rivers, and mountains to stay on course during their migration.

  4. Star Navigation: Some birds are able to navigate at night using the positions of stars in the sky.

  5. Inherited Knowledge: Young birds learn migration routes from their parents and other experienced individuals in their species.

By combining these different navigation methods, migratory birds are able to undertake their long journeys with remarkable precision and accuracy.
