Sensitivity of the homing pigeon to an Earth-strength magnetic field

THROUGH the use of a flight tunnel constructed within a controlled magnetic environment, it has been possible to train three pairs of homing pigeons (Columba livia) to discriminate between the presence and absence of a 0.5 gauss (Earth-strength) magnetic field. Successful discrimination was associated with flutter activity of the birds within the tunnel.
