Thank you! That’s it. I will correct my eBird post.

I searched for Olympic Gull on google and found a site called gull-research.org where I found some excellent pictures of an Olympic Gull. I never would have found the correct ID without help.

I spent yesterday with books and pictures on the internet and finally decided to list it on ebird as a Thayer's Gull. Now I'm having second thoughts, mostly because of the head and beak shape. I can almost see this bird frowning.
