Great Black-backed Gull

Tweet of the Day is a series of fascinating stories about the British birds inspired by their calls and songs.

Michaela Strachan presents the great black-backed gull. These gulls are the largest in the world. They are quite common around our coasts and you can see them in summer perched on a crag watching for any signs of danger or potential prey. Although they are scavengers Great Black-Backs will attack and kill other birds.
