Thanks for the new photo Tom, definitely a California Gull. A good example 
on how a single photo can be misleading. Some aspects said California Gull, 
others did not. The second photo looks all California. Points to consider 
are: dark eye at this stage; bicolored bill; bill not as thick as it 
appeared in the first shot, but long and parallel sided at the base; grey 
on mantle on the darker end of the scale, Ring-bill and Glaucous-winged are 
paler; definitely blackish primaries coming in; primaries missing but long 
winged look still apparent from this shot; body slimmer and not so rotund 
as Glaucous-winged or hybrid... etc.

cheers
