Common goldeneye
The common goldeneye ("Bucephala clangula") is a medium-sized sea duck of the genus "Bucephala", the goldeneyes. Its closest relative is the similar Barrow's goldeneye. 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").
