Sorry I don't know my Gulls and Terns very well. It was small, e.g. smaller than a Forsters Tern, and at times floating on the water picking at the surface almost like a Phalarope. The image was taken today in the San Francisco Bay area.
Looking at the Sibley I was thinking non-breeding Bonapertes Gull. But the black tips of the tail feathers don't fit. Although it would partially match a 1st winter BG. But then, it's July...
Thanks in advance. JR
