Abstract:Behavioral experiments concerning the homing abilities of pigeons were done by sectioning their lagenal nerves or interfering with the function of the lagena using a magnet. Twenty-one birds were treated in this way and 30 birds from the same loft of racing pigeons were used as controls. The results of homing tests clearly revealed a magnetic influence on the function of the lagena in terms of the navigation ability of pigeons: the treated birds were either lost or significantly delayed while the controls returned within 30 min of release. The lagena of birds is a unique organ and it is concluded that it is a key element in the magnetic sensory system of birds.
