Barolo shearwater
The Barolo shearwater (''Puffinus baroli''), also known as the North Atlantic little shearwater or Macaronesian shearwater, is a small shearwater which breeds in the Azores and Canaries of Macaronesia in the North Atlantic Ocean. The epithet commemorates the Italian marquis Carlo Tancredi Falletti di Barolo.
==Taxonomy==
It used to be considered conspecific with the little shearwater (''Puffinus assimilis'') of the Southern Hemisphere. Mitochondrial DNA cytochrome ''b'' sequence analysis (Austin ''et al.'', 2004) indicates, however, that ''baroli'' and ''boydi'' are very close to the nominate subspecies of Audubon's shearwater. Whether the morphological distinctness and the non-overlapping ranges, or the genetic similarity〔Note that mtDNA is of somewhat dubious value for species-level taxonomic revisions in Procellariiformes, due to these birds' long lifespan and some genetic peculiarities. ''See also'' Rheindt & Austin (2005).〕 are considered to be more significant is a matter of opinion, and the taxonomic status of these birds remains equivocal. Although some institutions (such as BirdLife International) retain the forms ''baroli'' and ''boydi'' within little shearwater, this is as a result of inaccurate lumping in the past, and is not supported by modern evidence. The British Ornithologists' Union has accepted ''P. baroli'' as a distinct species (Sangster et al. 2005), as has ''Clements Checklist''. The American Ornithologists' Union followed in 2013.
