|Great black-backed gull|
|Species:|| larus marinus|
The Great Black-backed Gull, or Larus marinus, are Europe’s largest gulls, and that have very dark grey (almost black) backs, hence their name.
The black-backed gull has black wings and back, with white underparts and head. Yellow bill with red part on lower section. Also has white daub at the end of the wing and pink legs.
Black-backed gulls can be very disruptive to sea bird colonies, as they harry the other birds and even eat eggs and chicks occasionally. Pairs, however, are often very solitary. Their laughing call is deeper than most gulls.
The black-backed gull feeds mainly on fish and carrion.
The great black-backed gull can be sighted in northern Spain to Iceland, through the North Sea, Baltic and Scandinavia.
