This gull appears to be a Glaucous-winged X Western hybrid. It is much too bulky and thick-billed for a Thayer's. It's at the lighter end of the Olympic Gull spectrum, but it doesn't really fit anything else.

I think this is too dark for a Thayer's/Iceland. Could be one parent by head shape and wing pattern but I suspect the other parent is something darker.
On the morning of 9/4 Tait and I were birding on the sandy flat at Broughton and spent a good bit of time photographing and observing an interesting gull. To my eyes it seems like a good contender for L.g. thayeri but it seems really early for such a bird. We went back and forth on several other possibilities such as an unusually petite Olympic-type hybrid, or a dark-eyed female Herring. We were gloriously interrupted with close views of a Sabine's that came in to rest on the beach right in front of us, and then got right back to puzzling over the bird I've placed in "Larus sp." on the attached eBird checklist. Any help would be appreciated.
