ID Challenge
For photos taken by Ryan O'Donnell

Following Buck's post on Saturday I went to the ponds west of the Logan
Landfill in search of Greater Scaup. I am still struggling to identify
these in the field, but I felt like there was at least one and probably
more that were Greaters. When I returned with a group of other birders
on Sunday morning we were unable to find any Greaters. I took a bunch of
photos on Saturday night and I wanted to solicit opinions on the three
shots I thought looked most like Greaters (these may or may not be the
same bird). I've based my ID primarily on the height and length of the
bill, the width of the bill, the size of the nail on the tip, the width
of the head at the "jowels", and partly on the shape of the head in
profile. The pure white flanks was a minor corroborating point. Here are
links to the photos:
Thanks for your help,
