I was wondering if someone could help me with a couple of gull IDs. These are both from Aurora Reservoir, where I thought I'd take a look at some of the birds seen yesterday. I'm larus challenged, however, so I could use all the help I can get.
The first bird, I'm calling an immature Glaucous Gull. It is a large bird, bi-colored (pink with black tip) bill, pink legs, pale color, whitish wingtips, dark eye:
The second I'm just calling a gull. I didn't notice any dark or black wing tips on this one. It also seemed bigger than all the birds around it and had a slightly less streaked head.
I apologize for the over sharpening and lack of perfect field mark views. There are other shots of these, and one I'm calling a Lesser Black-backed Gull.
