Barrow's Goldeneye (Bucephala islandica)

OTHER NAMES: N/A
Latin Etymology: Bucephala ("bull headed") islandica ("of Iceland")

Adult in eclipse plumage Barrow's Goldeneye (Bucephala islandica) at Saskatoon Lake, Alberta, Canada - July 2024


Featured Subspecies: N/A
Weight: 590-970g  /  Length: 43-49cm  /  Wingspan: 70-73cm
NO UK STATUS IUCN Red List: Least Concern

A species with a very perculiar range - it breeds in the Rockies up into Alaska, but also has a disjunct population in the Gulf of St Lawrence in Quebec, and, perhaps even more oddly, a relict population in Iceland in Europe.  In most plumages relatively simple to separate from the Common Goldeneye - in breeding males the face patch is a wedge rather than round, and in the breeding females the beak becomes orange, however, in eclipse it can become a bit subtler and features such as black wingbars and the head shape become required.
