Bucephala

Bucephala is a genus of diving ducks found in the Northern Hemisphere. The genus name is derived from Ancient Greek boukephalos, "bullheaded", from bous "bull", and kephale, "head", a reference to the crest of the bufflehead making its head look large.[1]

The bufflehead was formerly treated as the only member of the genus (sometimes unnecessarily changed to Charitonetta) while the goldeneyes were incorrectly placed in Clangula (as Clangula americana), the genus of the long-tailed duck, which at that time was placed in Harelda.[2] It may yet be correct to recognise two genera, as the bufflehead and the two goldeneyes are well diverged. In this case, Bucephala would be restricted to B. albeola and the name Glaucionetta (Stejneger, 1885) resurrected for the goldeneyes.
Species

The three living species are:

Image	Scientific name	Common name	Distribution
	Bucephala clangula	Common goldeneye	Canada and the northern United States, Scandinavia, the Baltic States, and northern Russia
	Bucephala islandica	Barrow's goldeneye	northwestern North America
	Bucephala albeola	Bufflehead	North America and the southern United States.

Known fossil taxa are:

Bucephala cereti (Sajóvölgyi Middle Miocene of Mátraszõlõs, Hungary - Late Pliocene of Chilhac, France)
Bucephala ossivalis (Late Miocene/Early Pliocene of Bone Valley, United States), which was very similar to the common goldeneye and may even have been a paleosubspecies or direct ancestor
Bucephala fossilis (Late Pliocene of California, United States)
Bucephala angustipes (Early Pleistocene of central Europe)
Bucephala sp. (Early Pleistocene of Dursunlu, Turkey: Louchart et al. 1998)
