观察细节
Single bird seen in close company with Lesser Scaup. Bird appeared somewhat larger with rounded head slightly peaking on forehead area. Bill larger and more spatulate. We do have photos. In general, separating the two scaup species is an under-appreciated identification challenge. Despite my years of experience with the birds, I am often far from certain about suspected Greaters at inland locations. I feel reasonably confident about this bird, but won’t die on the hill over this one.
