How birds can detect Earth’s magnetic field

Researchers at Lund University in Sweden have made a key discovery about the internal magnetic compass of birds. Biologists have identified a single protein without which birds probably would not be able to orient themselves using the Earth's magnetic field.

The receptors that sense the Earth's magnetic field are probably located in the birds' eyes. Now,...
