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.

Black-vented shearwater central and southern California during the country's colder months. The black-vented shearwater is thought to feed on mainly small fish. This bird nests in burrows and caves; it is a colonial nester. In the past, this bird had been threatened by feral cats and other predators on its breeding islands, but the problem seems to have been largely eliminated. There is some loss of birds from commercial gill netting, and the species is classified as near threatened by the IUCN mainly due to the uncertain impact on it by the expanding fishing industry.
