Photos of the gull are here:
https://www.flickr.com/photos/123166253@N05/sets/72157650700330615/
One of the photos shows the bird with wings outstretched, showing a
Thayer's-like wingtip pattern above (black on the outer webs of
primaries) and below (small amount of black visible around edges).
The other two photos show the bird sitting - one with a Herring Gull
in the foreground for comparison. The legs were a deep pink and the
head had a fair amount of streaking (although some of the Herring
Gulls present showed these characteristics as well). The rounded
head and relatively small-looking bill, combined with the pattern on
the wingtips, seem like the best reasons to call this a Thayer's.
Would be great to hear what others think.
Brian Whipple, Drew Haluska and I spent over an hour trying to
relocate the gull this afternoon, with no luck. This bird was seen
at the southwestern end of the reservoir, where a patch of open
water was drawing a lot of gulls closer to the edge of the reservoir
than they normally would be.

Sorry, the suspect is an ADULT gull.

Kai Sheffield and I are looking at gulls on the CP Reservoir, searching for one
that Kai spotted earlier and thinks may have been a possible Thayer's Gull.
He has photos, but we can't attach because they're on a point-and-click camera.
We know weird Herring Gulls can look like Thayer's. We are NOT calling this a
Thayer's, but if anyone nearby has a scope and wants to come look, please do,
and let us know.
