Great black backed gull

Description:

The Great Black-backed Gull (Larus marinus) is a very large gull which breeds on the European and North American coasts and islands of the North Atlantic. It is fairly sedentary, but some Great Black-backed Gulls move farther south or inland to large lakes or reservoirs. The Great Black-backed Gull was one of the many species originally described by Linnaeus in his 18th-century work, Systema Naturae, and it still bears its original name of Larus marinus.

Notes:

I never saw such a giant gull.
