i would call this a lesser scaup based on the relatively small, narrow bill nail. greater scaup have a much more prominent dark bill nail that has been described as the bird wearing lipstick. bit of an exaggeration but still a reliable characteristic for differentiating greater v. lesser. head shape and color can vary but the bill nail remains fixed. here's <https://www.birdzilla.com/bird-identification/id-skill-development/bird-families/waterfowl-identification/duck-identification/identification-of-diving-ducks/comparison-of-greater-and-lesser-scaup.html> a good look for comparison. ed mcvicker On Sun, Mar 28, 2021 at 2:00 PM Harry Fuller <atowhee...> wrote: > can't see head shape but this is female scaup...Greaters have round heads > while the more-often shallow-water > tolerant Lessers have angle at back of the head > > On Sun, Mar 28, 2021 at 1:17 AM joy shreyer <dmarc-noreply...> > wrote: > >> We saw this duck along with a male and female ring necked duck on Monday >> March 22 at Ridgefield NWR in WA.
