Since I have some past experience in South Korea, I sometimes get questions about IDs from there. I recently received a link to an ebird report from Seoul, South Korea from 31 December 2017 around which there is a debate about whether one bird reported is a Redhead, Common Pochard, or some kind of hybrid. I was thinking Redhead because of the sloping forehead, yellow eye, and bill that was not as horizontally held as Common Pochard. But I don’t have a high degree of confidence in my guess. Any ideas? Thanks.
