The Manx shearwater is a small member of the shearwater family. They have black upperparts, white lower parts and long and straight wings.
This shearwater flies with a series of swift, stiff beats to the wings over the seas surface.
These birds breed in colonies in the UK, usually offshore on islands - this is because it's clear of rats and other ground predators that pose a risk.
Their diets consist of fish, particularly herrings, sprats and sardines.
