Lesser Scaup

One key to separating Lesser from Greater Scaup is their head shape. Greater Scaup have relatively round head profiles, while Lessers heads have taller hind crowns. Sibley writes, “differences in head shape are easily seen on sleeping birds…Scaup  are often more easily identified when sleeping than when awake.” No doubt that this Texas duck from last March is a Lesser Scaup.
