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 ...

The magnetic compass that birds use for orientation is affected by polarized light. That is the finding of researchers in Sweden, who studied zebra finches navigating a simple maze and found that the ...

The magnetic compass of birds is light-dependent 9,10, and exhibits strong lateralization with input coming primarily from the right eye 11. However, the primary biophysical process underlying this ...

For three years, the experiment wouldn’t work, and Henrik Mouritsen couldn’t figure out why. He had captured European robins and placed them in funnel-shaped cage in a windowless room. The funnel was ...

While radio waves emitted by radio and television broadcasting and CB radio can disrupt the magnetic compass of migratory birds, those used in mobile communication networks do not because the ...

Loggerhead sea turtles (Caretta caretta) can learn to associate food with the geomagnetic signatures of various oceanic regions, suggesting that they are able to find known foraging areas using an ...
