Barolo shearwater 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 specific "baroli" refers to Carlo Tencredi Falletti, marquis of Barolo. It was previously considered conspecific with the little shearwater ("Puffinus assimilis") of the Southern Hemisphere.

Bulweria "b" sequence analysis has proven them to be closely related to the shearwaters in the genus "Puffinus" and especially the "Procellaria" petrels. Bulweria Bulweria is a genus of seabirds in the family Procellariidae named after English naturalist James Bulwer. The genus has two extant species, Bulwer's petrel ("B. bulwerii") and Jouanin's petrel ("B. fallax"). A third species, the Olson's petrel ("Bulweria bifax"), became extinct in the early 16th century; it is known only from skeletal remains. Bulwer's Petrel ranges in the Atlantic, Indian and Pacific Oceans, whereas Joaunin's Petrel is confined to the northwestern Indian Ocean. Olson's Petrel is known
