影音備註
Part of a huge flock (approx. 750) of Greater Scaup, spooked into flight. Later determined it was a large dog on a nearby dock that was spooking them.
觀察細節
Very large flock of ducks, counted first 100, then counted the remainder in 100’s - conservatively 800 in total. Small number of Mallards and Bufflehead among them, and a small number of Lesser Scaup could be seen with the bump on their heads (no more than 25). The remainder were Greater Scaup.
