Bird is dead center, looking to left, viewed from rear. Lack of black primaries, heavy bill, sloped forehead.
观察细节
Alex Bernzweig's "possible adult glaucous gull" reported earlier today, confirmed by Bob D. Seen at south boat ramp as Alex reported, along with Herring, Ring-Billed, and Black-Backed gulls. Light grey back, white edging to tips of wings, no black coloring in primaries as in Herring Gull. Bird was resting on ice so legs were not viewed. Heavy bill and sloped forehead. I considered Iceland Gull which I heard was at this location, but discounted due to heavy bill. See pic.
