Manx shearwater (Puffinus puffinus)

Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

Puffinus puffinus is a medium sized shearwater with long slim wings, reaching lengths of 35 cm with a wingspan of up to 83 cm. Uniformly sooty black upperparts are sharply demarcated from white underparts. The head is black to below the eye, and the black upperparts extend onto the sides of the breast. The bill is dark-grey to black, the legs and feet are very pale pink. Sexes and ages are similar in appearance.

Recorded distribution in Britain and Ireland

Large colonies breed on islands off the west coast of the UK during breeding season, March to July.

Habitat

The Manx shearwater breeds colonially in the UK on offshore islands where they are safe from predators. The nest is usually made in a burrow and visited at night. Breeding grounds are left in July for migration to South America, and the birds return in March.
