INTERESTING FACTS
The Great Black-backed Gull was originally described by Linnaeus in his 18th century work, Systema Naturae, and it still bears its original name of Larus marinus. In winter, large numbers eat fish driven to the surface by humpback whales. They can swallow a puffin or a small wild duck whole. It's feathers were used for fashionable clothing in the 1800s. After the demise of the feather trade in the early 1900s, their population increased.
