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 least 1337, but from as early as 1678 the term gradually came to be used for another, unrelated, seabird, the Atlantic puffin, an auk. The current English name was first recorded in 1835 and refers to the former nesting of this species on the Isle of Man.
The taxonomy of this group is the cause of much debate, and the number of recognised species varies with the source.
The species in this group are long-winged birds, dark brown or black above, and white to dark brown below. They are pelagic outside the breeding season. They are most common in temperate and cold waters.
These tubenose birds fly with stiff wings, and use a shearing flight technique to move across wave fronts with the minimum of active flight. Some small species, such as the Manx shearwater, are cruciform in flight, with their long wings held directly out from their bodies.
Many are long-distance migrants, perhaps most spectacularly the sooty and short-tailed shearwaters, which perform migrations of 14,000 km or more each year.
Puffinus shearwaters come to islands and coastal cliffs only to breed. They are nocturnal at the colonial breeding sites, preferring moonless nights to minimise predation. They nest in burrows and often give eerie contact calls on their night-time visits. They lay a single white egg.
