Tanghjørnet.
Female with a flock of Tufted Ducks. Separated easily by the pale and browner look, especially the pale patch at the front of the head. Is slightly bigger than tufted, but this is difficult to perceive here. Has become a more common winter visitor during later years around Amager.
♀.
The angle is a bit difficult but I think this is a normal pure pochard. Probably a young bird rather dark and with vague pattern in head and a bill that appears all black.
Saying this because there were two hybrid birds present in this raft of the birds. One positive hybrid with Ferruginous Duck, 4453, and the other probably too.
