I and several others saw a male wigeon this afternoon in SE Boulder Co (viewed from private property.) It looked distinctly different from the others around it, with a much buffier pate, slightly grayer sides, and much less of a green eye stripe. In some light its head showed an almost iridescent-looking cinnamon shine, though usually it seemed mostly gray.
Some not-so-great digiscoped cell phone pics are attached.
Do you all think this guy is within the normal range of American Wigeon variation, is it maybe still coming out of eclipse plumage, or might it have some Eurasian ancestors? Any opinions welcome!
