I encountered late in the afternoon today an adult plumaged white-winged gull at the edge of the open water at Lake Erie which had completely white primaries, pale grey mantle, light eye, rounded head, yellow bill with small red spot at the gonys, pale eye (clear not dusky) and very pink legs. The mantle was a pale grey, lighter than the Ring-bills and a nearby Thayer's. The head was white and unstreaked, except perhaps very faintly in certain light on the top of the head. I will admit my first thought was Glaucous Gull, but due to the overall size, head shape, delicate bill, leg color had me immediately pondering other options, such as Iceland or an aberrant Thayer's. I took some poor photos with my Lumix which I would like to send to someone to take a look at or perhaps post for wider review. If someone could get back to me, I would appreciate it.
