觀察細節
This duck was sleeping with 4 RB mergansers on the quiet back pond.It appears to us to have the rounded head of a greater scaup, and is equal in size to nearby RBME. Bill proportion to head size seems to fit greater scaup. Photo of group for scale and photos of duck when it popped up its head for a bit.
