Spotted by Joshua Malbin about 115 this afternoon, this report posted in Facebook North American Gulls group. Possibly a dark extreme Iceland Gull or leaning towards Thayers but I will post comment after experts weigh in.

Update. One of the comments I've read is the gull could be the. Kumielen Iceland gull, a darker than usual form.
In any case immature gulls are tough,not one of my favorite pastimes. 😊
