I'm not sure if this is an Iceland (Thayer's) gull. It has the dark eyes, pink legs, grey wings with darker tips. I think it is not a Herring gull due to dark eyes and wing tips not black. I am not sure if the wing tips are too light, but don't know what else it could be.

Hi Bill,

Looks like a Gaucous-winged Gull to me. The primaries are nearly the same grey as the birds mantle. Most other West Coast gulls have distictly dark primaries including Iceland gull.

Glaucous-winged and Western Gull in our region have a varying % of being mixed (hybrids) and that accounts for different shades of grey in the primaries. Often refereed to as Olympic Gulls. (Glaucous-winged X Western)
