Odd Gull

Wondering if these very poor photos can make this strange white gull identifiable to people who know gulls. It was at Road's End on May 17, all by itself.

Jeff Gilligan very quickly identified it as a pale, immature Glaucous-winged Gull. Thanks, Jeff.

I think this gull should learn to sit on light-colored rocks instead of black ones before it becomes dinner for an eagle. I've watched eagles dining on gulls here.
