Puffinus Puffinus Puffinus is a genus of seabirds in the order Procellariiformes. It comprises about 20 small to medium-sized shearwaters. Two other shearwater genera are named: "Calonectris", which comprises three or four large shearwaters, and "Ardenna" with another seven species (formerly often included within "Puffinus"). "Puffinus" is a New Latin loanword based on the English "puffin". The original Latin term for shearwaters was usually the catchall name for sea-birds, "mergus". "Puffin" and its variants, such as poffin, pophyn and puffing, referred to the cured carcass of the fat nestling of the shearwater, a former delicacy. The original usage dates from at
Bannerman's shearwater to feed on fish, squid and cephalopods, by surface-seizing, underwater pursuit, including diving and plunging, and pattering (del Hoyo et al. 1992, Brooke 2004). It is likely to nest in rock crevices or burrows and form colonies (del Hoyo et al. 1992). Bannerman's shearwater Bannerman's shearwater ("Puffinus bannermani") is a seabird in the Procellariidae family formerly considered conspecific with Audubon's shearwater ("Puffinus lherminieri"). Little is known of this species other than that it breeds in the Volcano Islands in the Ogasawara Group to the southwest of Japan and doesn't seem to range far from this area.
