This white-winged Gull was present on the sea front at Crescent City. I have spent some time trying to identify it but I believe that it a Glaucous-winged Gull. It was the only one we saw that day, very different from the only other occasion when we saw them in the city of Vancouver in 1997 where they were very common.
