Heavy bill with strongly curved tip and well pronounced gongs angle. Large red spot on bill reaching upper mandible. No streaking on the head whatsoever. Darker grey upper side than Caspian Gull. Head more rounded, not pear shaped like in Lesser Black-backed Gull. The white spot on H10 is separated by a black band from the white wing tip.
