Scientists edge closer to how pigeons read Earth’s magnetism
Pigeons have long stunned scientists with their ability to cross unfamiliar landscapes and still find their way home, even when landmarks vanish and the sky is overcast. Researchers are now closing in ...
Birds have a light-dependent compass in their eyes. This compass gives them information about the direction of the Earth's magnetic field. Researchers have now elucidated how this compass works at the ...

Pigeons Rely on the Earth’s Magnetic Field to Navigate. Now, Researchers May Have Uncovered How They Do It
In the late 1800s, the French naturalist Camille Viguier proposed an idea that would be dismissed and forgotten for more than ...
For decades, scientists have known that migratory birds use Earth’s geomagnetic field—along with light, stars, and other cues—to guide them on remarkably long journeys. But it is unclear just how ...
Monarch butterflies have a keen sense of direction, even on cloudy days. This is because they have a magnetic compass to direct their migration in addition to navigating by the position of the sun, ...
A compass made of light promises to be more sensitive than anything in a Boy Scout’s wildest dreams. A light beam shot through a blob of rubidium atoms can directly and reliably measure the size and ...
A cell in the eye may be worth two in the beak, at least when it comes to a migratory bird’s magnetic compass. In European robins, a visual center in the brain and light-sensing cells in the eye — not ...
NEW YORK – A new study suggests that monarch butterflies use an internal magnetic compass to help navigate on their annual migrations from North America to central Mexico. Scientists already knew they ...
The compass has been around pretty much forever. Current technology isn’t really that far from a magnetized sliver of metal floating on a cork, but that may be about to change. A group of physicists ...
