Observation details
Two female and one male scaup were observed on the drying pond to the north of Pond 1W. As shown in the photographs, the heads of the scaup are larger and less peaked at the rear than those of lesser scaup. The females have faint white ear patches sometimes visible on female greater scaup. (I am not referring to the white patches that are visible at the base of the bill, which are present in females of both species.) Wider black tips were present on he bills of the scaup than are present in lesser scaup, as demonstrated by the closeups of the male and the two female greater scaups' bills. The female fartherest to the right in the two top pictures appears smaller than the male and the other female. Judging by apparent size and not by field marks,(large, less peaked head, white ear patch, more black on bill) a case could be made for two greater scaup and one lesser scaup.
