Discover the hidden world of bird navigation— Science News, April 13, 1974
Birds possess a remarkable ability to navigate using various sensory cues, such as observing the sun, stars, and landmarks, as well as sensing the Earth’s magnetic field. Scientists are continuously uncovering the mysteries behind birds’ magnetic sense. While iron-rich cells in their beaks were initially thought to act as internal compasses, recent research indicates that proteins in their retinas, known as cryptochromes, play a crucial role in allowing birds to perceive the Earth’s magnetic field. Studies have shown that cryptochromes in migratory robins are particularly sensitive to magnetic fields, shedding light on their extraordinary navigation abilities.
