Another scaup to light my way to the fall! This bird's full nape continues without a break or notch to the high point of the crown, which is above or perhaps even slightly ahead of the eye; the forehead shows a subtle curve into a large, boat-shaped bill. Black covers the entire tip of the bill, reaching from the nail all the way out to the edge. Note, too, that the vermiculations visible on some of the back feathers are decidedly fine; compare that pattern to the rather coarse banding on the feathers of the back of our recent Lesser Scaup.

This is a Greater Scaup. But I don't know whether it's a male or a female: ideas?

Can we wait until getting the answer to yesterday's bird before replying? Based on that discussion, this is obviously some sort of scaup.

According to the translation of the Kalevala (the Finnish folk epic), the world was created from a scaup's eggs. It laid its eggs on a girl's knee whilst she was floating about, but she twitched when the nest got too hot, and the eggs fell off and broke.

I can say with some confidence that it is...a duck!
Afraid that I have not the foggiest idea of any more precise identification, though.
