[cobirds] Aythya ID question

Hi all -

So, I was looking at a bunch of Redheads and Ringnecks today, and saw another duck in the mix.  This one looked a little different, and I am wondering if it is a Greater (or Lesser) Scaup.  It is a female, which makes it a little more difficult to ID than the males, but I think the pictures show it well enough to determine what it is.  I am somewhat confused by the white around the eye (Ringneck?), but there is no obvious "spur" on the front side as the Ringneck should have.  It looks to be nearly the size of the female Canvasback, or about the size of a Gadwall, as shown in the pictures.  Is the head shape definitive for a Greater Scaup?  Or am I imagining things?  Any clarification on the details would be most helpful.

cheers -
