How migratory birds find their way
Migratory birds like the bar-headed goose navigate thousands of miles using magnetoreception, a biological ability to sense the Earth's magnetic field. Scientists believe this is achieved through specialized cells in the retina or magnetite particles in their beaks.
Why it matters
Understanding animal navigation provides insights into biological evolution and the sophisticated sensory capabilities of wildlife.
W hen I was growing up, I used to notice groups of birds with long, slender necks flying in a perfect V-formation high in the sky. These birds were especially noticeable during the winter months. I used to wonder where they were going and what kind of birds they were. Later, I learned that these were migratory birds called bar-headed geese.
