Actual count. One adult male, two adult female, one juvenile. Differentiated from lesser scaup by broad headwidth, particularly on the lower half of the head, and broad bill. Head shape generally consistent with greater scaup. Females have broad white band at base of bill, as opposed to the slightly thinner band more typical of lesser scaup. All together floating on water. Just downriver from Civitan Park Beach.
