Diving Ducks (Genus Aythya)

Aythya is a genus of diving ducks. It has twelve described species. The name Aythya comes from the Ancient Greek word αυθυια, aithuia, which may have referred to a sea-dwelling duck or an auklet.

Aythya shihuibas was described from the Late Miocene of China. An undescribed prehistoric species is known only from Early Pleistocene fossil remains found at Dursunlu, Turkey; it might however be referable to a paleosubspecies of an extant species considering its age (see also Greater scaup).
