After review and discussion, two Scaup look good for GRSC consideration. The two main traits that stick out to me are the long white wing stripe extending past the mid wing, and the thickness of the neck most noticeably at the base of the neck. Looking at Scaup that show a smaller wing stripe also appear to have a thinner neck while being in close proximity to the birds in question. See photos.
