"I would call this a molting juvenile Thayer's Gull. Cannot see the wing tips but can see the culmen-loral-eye relationship which speaks to Thayer's not to Herring. There are remaining worn brown juvenile scapulars, some with white edge spotting. There also appear to be a few fresher incoming first basic upper scapulars and these are darker and smaller. Mixed in with these are scapulars that may be new and look to be brownish gray in colour. A variegated appearance for sure on this bird. It is also rare to have photographed a early second calendar Thayer's that is not essentially in full juvenile plumage. " (Thanks to my friend Kevin for his insights)
