I have seen this bird on a number of occasions and have struggled with its ID. When I first saw it it was with a Ferruginous Duck and a Greater Scaup and I suspected that it could be a hybrid between these two species, showing rich mahogany tones to the plumage which could come from Ferruginous Duck (but are not so strong to be certainly so) and a white patch round the bill suggestive of Scaup. I've come up with various other ideas in the meantime but, with some help from Joern who has always favoured that ID, I am now back where I started. The bird is bulky and broad-bodied - for a while that made me wonder if a Netta species could be involved (Rosy-billed Pochard have been kept there) but this is probably more likely to have come from Greater Scaup.
