Glaucous-winged Gull

Howdy birdlady, i think the most salient point is the date of observation May. At best the mix up would be with a Mew Gull. Neither the Glaucus-winged or Glaucus Gull have Black in the Tail and this most certainly appears much darker than gray. The legs aren't in enuff light to be certain.

I believe the breeding California Gull has yellow legs and extensive black in the primaries. I also suggest it's not possible to tell a male and female gull apart by appearance. I think the bird in his first picture which was originally included with this picture on the same spotting, is a California Gull, but not this one. That is the confusion here I think?

this is a Breeding Male CA Gull
