觀察細節
Original comment before bird was confirmed by experts: Solid looks as it was seen well for about 10 minutes from Shooters foraging by the lift bridge in the feeding frenzies of gulls hammering the shad in the river. Train came by and all birds lifted and moved up river by Jacob’s Pavilion but this bird was not seen again. Overall very large gull, generally gray, low contrast appearance particularly when in flight. Adult colored gray scaps and mantle, muted gray/brown wingtips and tail, white rump, very “dirty” streaky head, dark eyes, mostly black bill. Jen Brumfield passed photos along to Amar Ayyash and word came that this was not a pure GWGU.
