Images in no particular order:
Left-center. Mantle color was a tad darker than surrounding HEGUs, but by a very slight amount. Decent general comparison to nearby HEGUs.
Dark iris, but when the light hit it just right I could see that it was a touch paler than the jet-black pupil.
Close-ups of wingtip. Primary tips were black (very HEGU-like).
Nice example of the bird's expression. Note the dark eye, forehead sloping into bill with yellow-green base, and soft/blurry streaking through the head onto the nape and breast. Orbital ring in the field was viewed as deep red-pink.
Just for fun, here's a pic of a dark-eyed "Kumlien's" Iceland Gull that was also present:
And a first-winter Glaucous Gull:
Congratulations Nick! This looks fantastic - just the sort of bird that I'd have loved to have found locally. I think I need to study your technique a bit more. What is it now - two visits to the landfill this fall and two 'mega' gulls. Nice work indeed.
ReplyDeleteCertainly looks more than interesting Nick. Let another ID Frontiers discussion begin!!!
ReplyDeleteIt has a lot of black on the wingtip. Aside from that, it looks pretty classic for Thayer's. I'd like to see a spread wing though. I've seen a grand total of 1 adult Thayer's Gull, so take my opinion for what it is.
ReplyDeleteGreat find..
ReplyDeleteI just found your site.
ReplyDeleteGreat stuff.
