Research on pigeon homing suggests that magnetic field information is used for orientation. The ability of pigeons to sense fields may be associated with a small, unilateral structure between the brain and skull which contains magnetite in what appears single domains.
Homing pigeons were equipped with a pair of small coils around their heads. Birds an induced field 0.6 gauss and the south magnetic pole up, oriented toward home normally under both sun overcast. polarity reversed when was visible but often flew away from
