I've been actively watching,studying and photographing gulls in Newfoundland for over 10 years. Every now and again, you get one that is just puzzling. I'd appreciate any ideas or comments on the following bird. The last 4 gull photos down is the gull in question.
Also for those interested there are a bunch of photos and commentary about dark winged adult Kumliens Gulls in St.John's Newfoundland.
