I just posted the shots. Interested in your ID. Thx

Also look at Ring-necked Duck. They look very similar to Scaup, but have some bands on the beak. If it is a Scaup though, you tell the difference between head shape (domed vs round). Then with males the amount of black on the tip of the bill is different, and on females the white cheek patch is more prominent on Greater Scaup. But once you upload it we should be able to tell!

@AshleyT I have new scaup flock spotting. These guys have a banded beak. Mentioned in both greater and lesser. What do you think? I'll post it as soon.

Correct. And when you compare it to photos of the Greater Scaup, yours have domed heads. And if you can't tell, it's always better to err on the side of caution and go with Lesser Scaup, they are much more common than Greater Scaup :)

After seeing the difference on your sightings, I agree. Thank you.

I was looking for a bit more pointed area on the head. Since I have not seen either I had thought that from descriptions that the head area needed to be more "pointed or domed" for the lesser?

Domed heads make these Lesser Scaup over Greater Scaup.
