Gulls plus need ID help in Help Me Identify a North American Bird Posted December 4, 2018 Haha. I like your humor. I understand there was a change with Iceland Gull and Thayer but not sure about what that is. Anyways, I have iBird Pro app and they still list the Iceland Gull. A bit out of it's way for Migration but still a line through Saskatchewan. Maybe a younger gull? I'll have to look up Kumlien's. Have not heard of it. Thanks again.
