Hi all,
I saw this gull sp. yesterday (May 20th) at Stow lake, Golden Gate park, San Francisco, CA and it has stumped me.
The bird associated with the Western Gulls that were present, and in flight it gave the impression of pale primaries. I have had various ideas on what it could be including Glaucous Winged Gull (though I am not convinced due to the primaries appearing slightly darker than the rest of the body). I have also thought Thayer's gull and even the possibility of a hybrid, though I would not be sure what the parent species would be.
