These ducks were part of a large mixed flock of Common Goldeneyes, Redheads, Greater Scaup, Lesser Scaup, Ring-necked Ducks, and American Coots.

There are two male Lesser Scaups in the foreground distinguished by the slightly crested peak of their heads behind their eyes and their tiny bill nails. In the background is a male Greater Scaup with its much more rounded head peaked above the eye and its noticeably larger bill nail.
