观察细节
Two different candidates. First three are clearly a hybrid in my opinion with extensive green on face. The second three I believe is a returning bird and probably a backcross with Eurasian Wigeon. Note freckled face which does not show up from a distance. Also more extensive postocular green. ID is provisional. Corrections welcome.
