|Barrow's Goldeneye (Bucephala islandica)
|WWT Barnes, London, England
Barrow's Goldeneye is found on both coasts of North America and in Iceland. I think that there is only one accepted record for Britain.
|They are slightly bigger than Common Goldeneye B. clangula with a longer, less triangular head. The white crescent on the lores reaches above the eye while in the Common Goldeneye it is a spot below the level of the eye. The back has more extensive black with small white "windows". The female is very similar to the female Common Goldeneye but the head shape is different.
My second photo is either a female or a juvenile. The colour of the iris is unusual.
