Bateleur

The Bateleur (Terathopius ecaudatus) is a medium-sized eagle in the bird family Accipitridae which also includes many other diurnal raptors such as buzzards, kites and harriers. It is the only member of the genus Terathopius and probably the origin of the "Zimbabwe bird", national emblem of Zimbabwe.
Bateleur eagles are among a group of raptors that secrete a clear, salty fluid from their nares whilst eating. According to Schmidt-Nielson's (1964) hypothesis, this is due to the general necessity for birds to use an extrarenal mechanism of salt secretion to aid water reabsorption.
