Sometimes hundreds of Greater Scaup gather at Wickiup Reservoir in the
early spring. Otherwise they are quite rare in Central Oregon.

Tim's statement about scaup abundance is more true in the north valleyand less true in Lane County, perhaps owing to the draw of Fern Ridge
Reservoir. Greater Scaup is regular on Kirk Pond below Fern Ridge Dam and
also on the Willamette River at Eugene. Lesser is more common but small
flocks of Greater do occur. Greaters seem to need "larger water" than do

Nagi, your picture shows a classic Lesser Scaup, no ambiguity about it.
theremy dad hunted scaup on Long Island Sound the Connecticut Fish and Game
employee used the measure of nail width on bills to distinguish the two
species, but he was using calipers. This scaup is alive and well, so its
head profile affords a good ID: somewhat flattish top to head, decided
crested look at the nape. Greater Scaup typically have a smooth curve
scaupat the nape, with possibly a slight angular break in that curve of the
profile nearer the top of the head.
Please correct me if I'm wrong folks, but isn't the default scaup in
shallow fresh water in western Oregon in winter the Lesser? And winter

Visitors to the Philomath Sewage Ponds this winter have occasionally
scrounged up one or two Greaters among the scores of Lesser Scaup. The
