I've got a bunch of Scaups' photos. I thought (haha) I was getting pretty good ID-ing them but got all confused now. They seem to change the shape of their head at will! :) It also looks quite different after diving.
Please help telling apart Greaters and Lessers!

They all taken in January-February, 2011 in Seattle Arboretum, WA

Fantastic photos! It's tougher with females, but I think I see all Greater Scaups. Nice wide, heavy bills, generally well-rounded heads. Tough to say with 100% certainty, but that's my take.

Out of curiosity, when and where were these taken?

On many of them, it looks like the head shape is a result of just coming up or preparing for a dive. I would call these lessers.

I agree many of them are Lessers. On #5 the black seems to extend from the nail onto the rest of the bill... normally a good mark for Greater. Just throwing that out there.

well, now im confused also, some look like lesser and some greater to me. i thought i could tell the difference between lesser and greater due to the head shape, bill size,etc but not anymore. :/ :P LOL
