Growing up in Northern Scandinavia, we always had this problem of the head colour of Goldeneyes. The Barrow’s Goldeneye commonly has a “purple head” and the Common Goldeneye commonly has a “green head”. However, depending on how the angle of sunlight hit the head, the iridescence off feathers would yield the exact opposite colour. This always results in the over-reporting of Common Goldeneyes in Lappland and of Barrow’s Goldenhead’s in more southern climes.
Visit the following website to see the same Common Goldeneye with what is obviously two completely different head colours.
I was wondering whether this may be a factor with the Baer’s Pochard in part anyway? Now I guess the only question is, “Do Hardheads’ Heads iridesce?” (Say that 5 times quickly) ;-)
