Observation details
Puzzling bird. I originally tried to make this a Glaucous Gull in the field based on what appeared to be pure white wingtips. But the bird appeared slightly smaller than nearby Herring Gulls, and the proportions are wrong (long primary projection, beak not heavy enough, and didn't have the heavy-chested + long-necked carriage of Glaucous Gull). My feeling is it is probably a very pale ICGU and that perhaps some wing markings were not visible. I never saw it in flight to confirm pure-white wingtips. Photos are iphone-through-the-scope, so there could be faint markings not visible.
