Stercorarius skua
The great skua is a rather crafty bird that harasses birds as large as gannets to steal food off to feed on. They are known to be aggressively natured and will kill and eat smaller birds - this includes puffins!
Great skuas aren't fearful when it comes to humans, and if you find yourself near their nests, you will often be dive-bombed by the angry adult.
From afar, they look dark but up close display whites and browns.
Their diets mainly consist of other birds, fish and carrion.
