The Hartford IL Mew Gull from Thur. flew to Bend rd. at days end today.

Here an adult winter Mew Gull. (American small-billed) L.c.brachyrynchus:
classic field marks: dark eye (mini Slaty-backed wing tips)
Here note: dove like jizz; lead grey mantle (less blue); small smudged bill (no ring);
P6 sub-terminal black band surrounded by white (up against the tertial crescent):
(looking like a piece of electrical tape on a marshmallow) 
Here shown with Ring-billed bills:
