Or as Joern described it himself, unusual American Wigeon, probably with Chiloe Wigeon genes. Perhaps that's a better way of describing it as what this probably isn't is a first-generation hybrid offspring of a pairing between an American Wigeon and a Chiloe Wigeon. If we're right in thinking Chiloe Wigeon genes are present, you will probably have to go further back than one generation to find the Chiloe Wigeon ancestor. It looks too much like an American Wigeon.
Wrong for pure American Wigeon, I think, is the head pattern. On American Wigeon the pale cream stripe extends from the forehead back to the centre of the crown, further back than on this bird. It also lacks the warm orangey tones that seem to be present on this bird. Other than that the bird is very close to American Wigeon, although a further discrepancy I think I can detect in one or two of the photos is pale whitish edges to some of the long scapulars. That's a feature that could indeed point to Chiloe Wigeon influence.
