Summary:
The European robin and other birds know where to migrate by
sensing the direction of the Earth's magnetic field. Researchers have recently
attributed this ability to a chemical reaction that takes place within the eye
and whose success depends on the field direction. However, researchers now
report that the current form of this 'radical-pair mechanism' is not sensitive
enough to explain the disruption of the avian magnetic compass by certain
radiofrequency magnetic fields.
