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.
