Behavioral experiments, mostly with migrating passerines, revealed three characteristics of the avian magnetic compass: 1 it works spontaneously only in a narrow functional window around the intensity of the ambient magnetic field, but can adapt to other intensities, 2 it is an "inclination compass", not based on the polarity of the magnetic field, but the axial course of the field lines, and 3 it requires short-wavelength light from UV to 565 nm Green
