Weird Gull

It was an awesome day of birding on Jekyll today. It was high tide in the morning so we headed right out to the south end. Warblers, flycatchers, mimic thrushes and one stunting look at a Sedge Wren slowed us on the way out to the beach. I eased out so the birds would get used to us. The first bird that caught my attention was a very large pale gull. First impression was Glaucous Gull. It was next to an adult Herring Gull and it was a little larger but not enough for Glaucous Gull. As we watch the bird flew just a few feet so we saw the wings which were very pale but the wing tips were coffee colored as was the tail band. Here a photo of the gull. Any ideas? I threw in some young Herring Gulls to compare.
