Similar Species

Manx Shearwater, Little Shearwater, Boyd's Shearwater and Audubon's Shearwater.

Distribution

Breeds in the northern Atlantic on Azores, Desertas, Salvage and Canary Islands.

Taxonomy

This is a monotypic species.
Clements[1] and Gill and Donsker[2] agree on the taxonomy of this species. Dickinson[3] however treats the shearwaters differently.
Barolo Shearwater was formerly considered to be a subspecies of Little Shearwater. It was later split together with Boyd's Shearwater as Macaronesian Shearwater which was split again into two monotypic species. Dickinson follows Austin and others and has transferred baroli (and boydi) to Audubon's Shearwater.

Habitat

Breeds on islands and coastal cliffs, otherwise pelagic.

Behaviour

Flight

Often holds head up. Quick wingbeats.

Breeding

Nests are made in burrows, in small colonies.

Diet

Diet includes fish and molluscs.
