Manx shearwater
Despite the scientific name, Puffinus puffinus, the Manx Shearwater is completely unrelated to puffins - the only resemblance is that they are both burrow-nesting seabirds.
It lives predominantly at sea and has long, narrow wings and feet placed far back on its body which makes it efficient for swimming. Manx Shearwaters are not so well suited to land - they cannot walk properly and shuffle along on their belly, making them easy prey for predators such as gulls.
Manx Shearwaters travel huge distances during migration. Studies on Skokholm and Skomer islands off the Welsh coast show that some of the young make the 6000 - 7000 mile journey in less than a fortnight.
Their diet is made up almost entirely of fish, especially herrings, sardines and sprats.
The Manx Shearwater only returns inland to breed. Breeding takes place on a few islands off the west coast of the UK, especially Skomer and Skokholm in Wales where there are an estimated 120,000 and 45,000 breeding pairs respectively, making the two islands the largest known concentration of this species in the world.
The prefix Manx, meaning from the Isle of Man, originated owing to the once large colony of Manx Shearwaters found on the Calf of Man - a small island just south of the Isle of Man.
