“Great Black-backed Gulls” is the name of this photo which was taken today at the entrance of St. John’s Harbor. Some facts include:
The largest gull in the world, the Great Black-backed Gull is primarily a coastal species. A bird of the North Atlantic, it has been expanding its breeding and wintering ranges farther south along the East Coast and into the Great Lakes.
The Great Black-backed Gull is one of the many 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 the species spread farther south. The exploitation of human refuse undoubtedly has contributed to the successful spread of the species.
In winter, large numbers of young Great Black-backed Gulls eat fish driven to the surface by humpback whales.
