Barolo shearwater a distinct species (Sangster et al. 2005), as has "Clements Checklist". The American Ornithologists' Union followed in 2013. Features that distinguish the Barolo shearwater from the Manx shearwater and other North Atlantic "Puffinus" species include the pale face, silvery panel in the upperwings, shorter more rounded wings, and blue feet. As well as the pale face with the darkly contrasting eye. The Baraolo shearwater occurs in the Macaronesian Islands and breeds on the Azores, Desertas, Selvagens and Canary islands.

Galápagos shearwater white. It sometimes has a dark collar. Both sexes are alike, as are the young after fledging. It is a slender-bodied shearwater, about 29–31 cm long, with a wingspan of around 63 cm and weighs 123-225 g. The species closely resembles the tropical shearwater, although the latter is typically blacker and has a longer tail. The Galápagos shearwater is a gregarious species and will feed at sea with other shearwaters and boobies. It flies low over the water and feeds on squid, fish and offal. It intersperses 4-10 stiff wing beats with shallow glides. Galápagos shearwater The Galápagos shearwater ("Puffinus
