Aythya hybrid in Dumfries & Galloway

Illustrating a potential pitfall, this presumed Tufted Duck x Scaup at Castle Loch was originally identified as a drake Lesser Scaup.

Note the head shape, the much finer vermiculations and the large black nail on the tip of the bill, all helping to eliminate Lesser Scaup. Photos by Jim Woods.
