This is the largest gull in the world.
The Great Black-backed Gull is one of many bird species whose feathers were used for fashionable clothing in the 1800s. After the demise of the feather trade in the early 1900s, Great Black-backed Gull populations increased and spread farther south. Garbage dumps and other sources of human refuse have contributed to their range expansion.
