The great black-backed gull is a very large member of the gull family. They have large, yellow, powerful beaks with pinkish feet. Adults are much blacker than the younger birds.
Whilst perched, they can sometimes look hunched.
Like most other gulls, they are competitive for food and will fight off and chase other birds that try to snatch food.
Their diets mainly consist of carrion, shellfish and other birds.
