Common Goldeneye (Bucephala clangula)

OTHER NAMES: Goldeneye, Whistler, Cobhead, American Goldeneye
Latin Etymology: Bucephala ("bull headed") clangula ("to resound")
Adult male Common Goldeneye (subspecies B. c. clangula) at Rutland Water, Rutland - April 2013

Featured Subspecies: Bucephala clangula clangula
Weight: 500-1400g  /  Length: 40-52cm  /  Wingspan: 77-83cm
UK AMBER LIST / IUCN Red List: Least Concern

Although some birds do breed in Scotland, this is primarily a Winter migrant to most of Britain. The male is a relatively striking bird with the large white spot between it's beak and eye being the easiest way to identify it. Less prominent is the female, which might require slightly more effort to identify as it lacks high contrast plumage, but has a fairly distinct squashed face for a duck.  I found them to be fairly abundant in Hokkaido in particular in Japan, present on the rivers in the Kushiro.
