The genus Bucephala was introduced in 1858 by American naturalist Spencer Baird with the bufflehead as the type species. [1] [2] The genus name is derived from Ancient Greek βουκέφαλος bouképhalos, meaning ' bullheaded ', from boûs ' bull ', and kephalḗ, ' head ', a reference to the crest of the bufflehead making its head look large.
The genus name is derived from the Ancient Greek boukephalos ("bullheaded", from bous, "bull " and kephale, "head"), a reference to the bulbous head shape of the bufflehead. The species name is derived from the Latin clangere ("to resound"). Common goldeneyes are aggressive and territorial ducks, and have elaborate courtship displays. [2]

The female will lay a clutch of 7–15 eggs but only begins incubation when the last egg has been laid, thereby permitting synchronous hatching. All hatchlings are consequently of the same size, which facilitates efficient parental care. During incubation, the female may lose anywhere from 8% to 16% of her body weight.
