This hybrid is not very dissimilar to Gadwall x Eurasian Wigeon, but that hybrid tends to be greyer on the flanks and scapulars - on this bird the flanks show the vinous pink colour typical o male American Wigeon. Joern has pointed out that both can show a different head pattern, with a pale front.
