Intermedius Lesser Black-backed Gull, Brier Island

Report from Eric Mills....
Among the gulls feeding in Pea Jack Cove at high water and in a gale late this afternoon was a very dark Lesser Black-backed Gull that was hard to pick out from the Great Black-backs and showed very little contrast between mantle and wing tip intensity. It had relatively large primary spots, eliminating (onthat feature and others) ''Baltic'' Gull. Sure looked like the W European intermedius to me.
