Scientists probe how pigeons use magnetism to navigate

Scientists are investigating how pigeons detect and use Earth's magnetic field for navigation. Researchers propose that the liver may be the key organ responsible for sensing magnetic cues.

Understanding magnetoreception mechanisms contributes to evolutionary biology and neuroscience. Such discoveries can inspire biomimetic applications and advance navigation technologies.

Homing pigeons rely on a variety of signals to navigate, including magnetism. But it hasn't been clear how they detect magnetic cues. Researchers propose the answer may be found in the birds' livers.
