Greater Scaup (Aythya marila) male and female

2009-8-22 by Karen - Reykjavik, Iceland
Checking breeding, feeding, migration maps for this part of the world, the Lesser Scaup sticks to Africa and breeds only on the northernmost edge of Africa. It doesn't appear in Europe and surely not in Iceland. I suppose from time to time a vagrant might appear, but since were talking about a small raft of ducks here in Reykjavik, I think it's safe to call it Greater Scaup which, incidentally, doesn't venture into Africa (according to the maps I checked).
