This shot clearly shows the ring neck which does not always show… so nice that you caught that. You are right about the bill and how I identify them at a distance compared to Scaups.
A very nice catch, Allen. This should go in a field guide-along with the image that shows the normal look! I took one of this species the last time I was at a refuge and I could just barely make out the ring-but only because I knew it was supposed to be there. So many of these names are legacies of the era when you shot them to ID them.
