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. "Puffinus" is a New Latin loanword based on the English "puffin" and its variants, such as poffin, pophyn and puffing, that referred to the cured carcass of the fat nestling of the Manx shearwater, a former delicacy. 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. Mitochondrial
Procellariidae with "Pseudobulweria" being phylogenetically closer to the "Puffinus" shearwaters than the "Pterodroma" gadfly petrels, and "Aphrodroma" (the Kerguelen petrel) possibly being closely related to the shearwaters or the fulmars. The prions, according to Nunn and Stanley, were among the larger shearwater group. The "Calonectris" shearwaters were placed close to the two "Puffinus" clades (closer to the Puffinus, or small, clade) and both were distant to the "Procellaria" shearwaters. The relationships between the genera and within the genera are still the subject of debate, with researchers lumping and splitting the species and genera within the family and arguing about the position
