Cosmeston



Interesting Aythya hybrid on W lake Cosmeston this morning. Looked superficially like Lesser Scaup, but had bronzy tinge to head and was slightly bulkier than Tufted. When Lawrence arrived with his scope, the black bill nail could be seen the too extensive. Nape was flat-ish but not flat enough IMO although it did have the small bump at the join of nape & crown. Back was nicely vermiculated grey. You have to wonder whether the regular Lesser Scaup is cross-breeding.

Also present of interest, 1 drake Wigeon and 3 Gadwall
