Revision as of 12:42, 15 September 2012
- Puffinus boydi
Identification
25-30cm
- Very dark upperparts
- Pale area on upperside of secondaries, more so on worn birds
- White underparts
- Underwing very white with thinner black trailing edge than similar species
- Wings shorter and rounder than similar species; does not reach tip of tail on resting bird
- Body relatively longer than similar species
- White cheeks extend up to sides of crown encircling dark eye
- Rounded head
- Dark peak reaching slightly down into the white underside behind head
- Slim bill shorter than similar species

Similar Species
Manx Shearwater, Little Shearwater, Barolo Shearwater and Audubon's Shearwater.
Distribution
Breeds in the northern Atlantic on Cape Verde Islands.
Taxonomy
This species is a recent split from Little Shearwater. It's sometimes considered conspecific with Barolo Shearwater and then named Macaronesian Shearwater.
This is a monotypic species.
Austin and others in 2004 suggested a radical revision of the taxonomy of small shearwaters. If their proposals are followed, Little Shearwater will contain five subspecies: assimilis, tunneyi, kermadecensis, haurakiensis, and elegans. Subspecies baroli and boydi would be transferred to Audubon's Shearwater or treated as one (Macaronesian Shearwater) or two full species (Barolo and Boyd's Shearwater). In partial acceptance of these data, myrtae has been transferred to Newell's Shearwater (currently treated as part of Townsend's Shearwater in Opus)
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.
