Puffins are any of three small species of alcids (auks) 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 (up to 400 times per minute)^[1] in swift flight, often flying low over the ocean's surface.

Taxonomy

The rhinoceros auklet (Cerorhinca monocerata) has sometimes been included in the genus Fratercula,^[2] and some authors place the tufted puffin in the genus Lunda.^[3] The puffins and the rhinoceros auklet are closely related, together composing the subfamily Fraterculini.^[4]

The genus name Fratercula is derived from Latin and means "little brother", a reference to the black and white plumage, which resembles monastic robes. The English name "puffin" was originally applied to the Manx shearwater which (in 1652) was known as the "Manks Puffin". Puffin is an Anglo-Norman word (Middle English pophyn or poffin)^[5] for the cured carcasses of nestling Manx shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits.^[6] The name has been applied to the related Razorbill in Ireland.^[5]

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.^[7] Fossils from North Carolina were originally thought to have been of two Fratercula species,^[8] but were later reassigned to one Fratercula, the tufted puffin, and a Cerorhinca species.^[9] Another extinct species, Dow's puffin (Fratercula dowi) was found on the Channel Islands of California until the Late Pleistocene or early Holocene.^[4]

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.^[9]

Description

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.^[10]

Although the puffins are vocal at their breeding colonies, they are silent at sea. They fly relatively high above the water, typically 10 m (33 ft) as compared with the 1.6 m (5.2 ft) of other auks.^[11]

Behaviour

Breeding

Puffins breed in colonies on coasts and islands; several current or former island breeding sites are referred to as Puffin Island. The male Atlantic puffin builds the nest and exhibits strong nest-site fidelity. Both sexes of the horned puffin help to construct their nest. Horned puffin burrows are usually about 1 meter (3.3 feet) deep, ending in a chamber, while the tunnel leading to a tufted puffin burrow may be up to 2.75 meters (9.0 feet) long. The nesting substrate of the tufted and Atlantic puffins is soft soil, into which tunnels are dug; in contrast the nesting sites of horned puffins are rock crevices on cliffs.^[15] The Atlantic puffin burrow is usually lined with material such as grass, leaves and feathers but is occasionally unlined. The eggs of the Atlantic puffin are typically creamy white but the odd egg is tinged lilac.

Where rabbits breed, sometimes Atlantic puffins breed in rabbit burrows.

Puffins form long-term pair bonds or relationships. The female lays a single egg, and both parents incubate the egg and feed the chick (or "puffling"^[16]). The incubating parent holds the egg against its brood patch with its wings. The chicks fledge at night. After fledging, the chicks spend the first few years of their lives at sea, returning to breed about five years later. Puffins in captivity have been known to breed as early as three years of age.

After breeding, all three puffin species winter at sea, usually far from coasts and often extending south of the breeding range.^[10]

Iceland is the home to most of the Atlantic puffins with about 10 million individuals.^[17] The largest single puffin colony in the world is in Westmann Isles, islands that belong to Iceland. In 2009, scientists estimated the number of nests to be 1.1 million,^[18] and number of individuals there is estimated to be up to 4 million.^[17]

Feeding

Like many auks, puffins eat both fish and zooplankton, but feed their chicks primarily with small marine fish several times a day. The prey species of the Atlantic puffin include the sandeel, herring and capelin.^[19][20] The puffins are distinct in their ability to hold several (sometimes over a dozen) small fish at a time, crosswise in their bill, rather than regurgitating swallowed fish. This allows them to take longer foraging trips, since they can come back with more food energy for their chick than a bird that can only carry one fish at a time. This behaviour is made possible by the unique hinging mechanism of their beak, which allows the upper and lower biting edges to meet at any of a number of angles.

Relationships with humans

Hunting

Puffins are hunted for eggs, feathers and meat. Atlantic puffin populations drastically declined due to habitat destruction and exploitation during the 19th century and early 20th century. They continue to be hunted in Iceland and the Faroe Islands.^[21]

On the Blasket Islands off the coast of County Kerry, which were abandoned in 1953, the islanders, who often lived just above starvation level, hunted and ate puffins in large numbers.

The Atlantic puffin forms part of the national diet in Iceland, where the species does not have legal protection. Puffins are hunted by a technique called "sky fishing", which involves catching low-flying birds with a big net. Their meat is commonly featured on hotel menus. The fresh heart of a puffin is eaten raw as a traditional Icelandic delicacy.^[22]

Related places and products

The name of the English island Lundy is believed to come from the old Norse word for "puffin island" (Lundey),^[23] however an alternative explanation has been suggested with Lund referring to a copse, or wooded area.^[24]

The Atlantic puffin is the provincial bird of the Canadian province of Newfoundland and Labrador.
