Just a few gulls in flight. At least one is a Ring-billed Gull. I think one is a Herring Gull. The other, with the lighter background, I’m not sure about. It might be a juvenile California Gull in a late stage of its second year. The bill is really what’s throwing me off…I don’t yet know enough about identifying bird species to figure out how that light colored bill and ring with a yellow spot fits into the huge variety of juvenile gull morphs there are.
