Mixed in with the raft of Coots, I talked about yesterday, was also some Scaup. I looked at these ducks for a long time and even sent them to my birding mentor HAP for conformation that they were Greater Scaup. (Lifer #132 and Yard Bird #122). The males are easy to see with their greenish/brown heads that also can look black depending on the light. The females have a large white patch at the base of the beak.
