Puffin, Sea Parrot (c1833). Etching, watercolor. 65 x 100. Puffins are any of three small species of alcids in the bird genus Fratercula with a brightly coloured beak during the breeding season. These are pelagic seabirds that feed primarily by diving in the water. They breed in large colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the tufted puffin and horned puffin, are found in the North Pacific Ocean, while the Atlantic puffin is found in the North Atlantic Ocean. All puffin species have predominantly black or black and white plumage, a stocky build, and large beaks. They shed the colourful outer parts of their bills after the breeding season, leaving a smaller and duller beak. Their short wings are adapted for swimming with a flying technique under water. In the air, they beat their wings rapidly in swift flight, often flying low over the ocean's surface. A significant decline in numbers of puffins on Shetland is worrying scientists. The genus Fratercula was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the Atlantic puffin as the type species. The name Fratercula is Latin for little brother, a reference to the black and white plumage, which resembles monastic robes. The English name puffin-puffed in the sense of swollen-was originally applied to the fatty, salted meat of young birds of the unrelated Manx shearwater, formerly known as the Manks puffin. Puffin is an Anglo-Norman word for the cured carcasses of nestling Manx shearwaters. The genus contain three species. The rhinoceros auklet has sometimes been included in the genus Fratercula, and some authors place the tufted puffin in the genus Lunda. The puffins and the rhinoceros auklet are closely related, together composing the subfamily Fraterculini. The oldest alcid fossil is Hydrotherikornis from Oregon dating to the Late Eocene while fossils of Aethia and Uria go back to the Late Miocene. Molecular clocks have been used to suggest an origin in the Pacific in the Paleocene. Fossils from North Carolina were originally thought to have been of two Fratercula species, but were later reassigned to one Fratercula, the tufted puffin, and a Cerorhinca species. Another extinct species, Dow's puffin was found on the Channel Islands of California until the Late Pleistocene or early Holocene. The Fraterculini are thought to have originated in the Pacific primarily because of their greater diversity there; there is only one extant species in the Atlantic, compared to two in the Pacific. The Fraterculini fossil record in the Pacific extends at least as far back as the middle Miocene, with three fossil species of Cerorhinca, and material tentatively referred to that genus, in the middle Miocene to late Pliocene of southern California and northern Mexico. Although there no records from the Miocene in the Atlantic, a re-examination of the North Carolina material indicated that the diversity of puffins in the early Pliocene was as great in the Atlantic as it is in the Pacific today. This diversity was achieved through influxes of puffins from the Pacific; the later loss of species was due to major oceanographic changes in the late Pliocene due to closure of the Panamanian Seaway and the onset of severe glacial cycles in the North Atlantic. The puffins are stocky, short-winged and short-tailed birds, with black upper parts and white or brownish-grey underparts. The head has a black cap, the face is mainly white, and the feet are orange-red. The bill appears large and colourful during the breeding season. The colourful outer part of the bill is shed after the breeding season, revealing a smaller and duller true bill beneath. Although the puffins are vocal at their breeding colonies, they are silent at sea. They fly relatively high above the water, typically 10 m as compared with the 1.6 m of other auks.
