The great auk (Pinguinus impennis) is an extinct species of flightless alcid that became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus. It is not closely related to the birds now known as penguins, which were discovered later and so named by sailors because of their physical resemblance to the great auk.
It bred on rocky, isolated islands with easy access to the ocean and a plentiful food supply, a rarity in nature that provided only a few breeding sites for the great auks. When not breeding, they spent their time foraging in the waters of the North Atlantic, ranging as far south as northern Spain and along the coastlines of Canada, Greenland, Iceland, the Faroe Islands, Norway, Ireland, and Great Britain.
The great auk was 75 to 85 cm (30 to 33 in) tall and weighed about 5 kg (11 lb), making it the second-largest member of the alcid family (Miomancalla was larger). It had a black back and a white belly. The black beak was heavy and hooked, with grooves on its surface. During summer, great auk plumage showed a white patch over each eye. During winter, the great auk lost these patches, instead developing a white band stretching between the eyes. The wings were only 15 cm (5.9 in) long, rendering the bird flightless. Instead, the great auk was a powerful swimmer, a trait that it used in hunting. Its favourite prey were fish, including Atlantic menhaden and capelin, and crustaceans. Although agile in the water, it was clumsy on land. Great auk pairs mated for life. They nested in extremely dense and social colonies, laying one egg on bare rock. The egg was white with variable brown marbling. Both parents participated in the incubation of the egg for around 6 weeks before the young hatched. The young left the nest site after 2–3 weeks, although the parents continued to care for it.
The great auk was an important part of many Native American cultures, both as a food source and as a symbolic item. Many Maritime Archaic people were buried with great auk bones. One burial discovered included someone covered by more than 200 great auk beaks, which are presumed to be the remnants of a cloak made of great auk skins. Early European explorers to the Americas used the great auk as a convenient food source or as fishing bait, reducing its numbers. The bird's down was in high demand in Europe, a factor that largely eliminated the European populations by the mid-16th century. Scientists soon began to realize that the great auk was disappearing and it became the beneficiary of many early environmental laws, but this proved ineffectual.
Its growing rarity increased interest from European museums and private collectors in obtaining skins and eggs of the bird. On 3 June 1844, the last two confirmed specimens were killed on Eldey, off the coast of Iceland, ending the last known breeding attempt. Later reports of roaming individuals being seen or caught are unconfirmed. A record of one great auk in 1852 is considered by some to be the last sighting of a member of the species. The great auk is mentioned in several novels and the scientific journal of the American Ornithologists' Union is named The Auk in honour of this bird.
Analysis of mtDNA sequences has confirmed morphological and biogeographical studies suggesting that the razorbill is the closest living relative of the great auk. The great auk also was related closely to the little auk (dovekie), which underwent a radically different evolution compared to Pinguinus. Due to its outward similarity to the razorbill (apart from flightlessness and size), the great auk often was placed in the genus Alca, following Linnaeus.
The fossil record (especially the sister species, Pinguinus alfrednewtoni) and molecular evidence show that the three closely related genera diverged soon after their common ancestor, a bird probably similar to a stout Xantus's murrelet, had spread to the coasts of the Atlantic. Apparently, by that time, the murres, or Atlantic guillemots, already had split from the other Atlantic alcids. Razorbill-like birds were common in the Atlantic during the Pliocene, but the evolution of the little auk is sparsely documented. The molecular data are compatible with either possibility, but the weight of evidence suggests placing the great auk in a distinct genus. Some ornithologists still believe it is more appropriate to retain the species in the genus Alca. It is the only recorded British bird made extinct in historic times.
Pinguinus alfrednewtoni was a larger, and also flightless, member of the genus Pinguinus that lived during the Early Pliocene. Known from bones found in the Yorktown Formation of the Lee Creek Mine in North Carolina, it is believed to have split, along with the great auk, from a common ancestor. Pinguinus alfrednewtoni lived in the western Atlantic, while the great auk lived in the eastern Atlantic. After the former died out following the Pliocene, the great auk took over its territory. The great auk was not related closely to the other extinct genera of flightless alcids, Mancalla, Praemancalla, and Alcodes.
The great auk was one of the 4,400 animal species formally described by Carl Linnaeus in his eighteenth-century work, Systema Naturae, in which it was given the binomial Alca impennis. The name Alca is a Latin derivative of the Scandinavian word for razorbills and their relatives. The bird was known in literature even before this and was described by Charles d'Ecluse in 1605 as Mergus Americanus. This also included a woodcut which represents the oldest unambiguous visual depictions of the bird.
The species was not placed in its own scientific genus, Pinguinus, until 1791. The generic name is derived from the Spanish and Portuguese name for the species, in turn from Latin pinguis meaning 'plump', and the specific name, impennis, is from Latin and refers to the lack of flight feathers or pennae.
The Irish name for the great auk is 'falcóg mhór', meaning 'big seabird/auk'. The Basque name is arponaz, meaning "spearbill". Its early French name was apponatz. The Norse called the great auk, geirfugl, which means "spearbird". This has led to an alternative English common name for the bird, "garefowl" or "gairfowl". The Inuit name for the great auk was isarukitsok, which meant "little wing".
The word "penguin" first appears in the sixteenth century as a synonym for "great auk". Although the etymology is debated, the generic name, "penguin", may be derived from the Welsh pen gwyn "white head", either because the birds lived in Newfoundland on White Head Island (Pen Gwyn in Welsh), or, because the great auk had such large white circles on its head. When European explorers discovered what today are known as penguins in the Southern Hemisphere, they noticed their similar appearance to the great auk and named them after this bird, although biologically, they are not closely related. Whalers also lumped the northern and southern birds together under the common name "woggins".
Standing about 75 to 85 centimetres (30 to 33 in) tall and weighing approximately 5 kilograms (11 lb) as adult birds, the flightless great auk was the second-largest member of both its family and the order Charadriiformes, surpassed only by the mancalline Miomancalla. The great auks that lived farther north averaged larger in size than the more southerly members of the species. Males and females were similar in plumage, although there is evidence for differences in size, particularly in the bill and femur length. The back was primarily a glossy black, and the belly was white. The neck and legs were short, and the head and wings small. The great auk appeared chubby due to a thick layer of fat necessary for warmth. During summer, it developed a wide white eye patch over each eye, which had a hazel or chestnut iris. During winter the great auk moulted and lost this eye patch, which was replaced with a wide white band and a gray line of feathers that stretched from the eye to the ear. During the summer, the its chin and throat were blackish-brown and the inside of the mouth was yellow. In winter, the throat became white. Some individuals reportedly had grey plumage on their flanks, but the purpose, seasonal duration, and frequency of this variation is unknown. The bill was large at 11 centimetres (4.3 in) long and curved downward at the top; the bill also had deep white grooves in both the upper and lower mandibles, up to seven on the upper mandible and twelve on the lower mandible in summer, although there were fewer in winter. The wings were only 15 centimetres (5.9 in) in length and the longest wing feathers were only 10 centimetres (3.9 in) long. Its feet and short claws were black, while the webbed skin between the toes was brownish black. The legs were far back on the bird's body, which gave it powerful swimming and diving abilities.
Hatchlings were described as grey and downy, but their exact appearance is unknown, since no skins exist today. Juvenile birds had fewer prominent grooves in their beaks than adults and they had mottled white and black necks, while the eye spot found in adults was not present; instead, a grey line ran through the eyes (which still had white eye rings) to just below the ears.
Great Auk calls included low croaking and a hoarse scream. A captive great auk was observed making a gurgling noise when anxious. It is not known what its other vocalizations were, but it is believed that they were similar to those of the razorbill, only louder and deeper.
The great auk was found in the cold North Atlantic coastal waters along the coasts of Canada, the northeastern United States, Norway, Greenland, Iceland, the Faroe Islands, Ireland, Great Britain, France, and the Iberian Peninsula. Pleistocene fossils indicate the great auk also inhabited Southern France, Italy, and other coasts of the Mediterranean basin.
The great auk left the North Atlantic waters for land only to breed, even roosting at sea when not breeding. The rookeries of the great auk were found from Baffin Bay to the Gulf of St. Lawrence, across the far northern Atlantic, including Iceland, and in Norway and the British Isles in Europe. For their nesting colonies the great auks required rocky islands with sloping shorelines that provided access to the sea. These were very limiting requirements and it is believed that the great auk never had more than 20 breeding colonies. The nesting sites also needed to be close to rich feeding areas and to be far enough from the mainland to discourage visitation by predators such as humans and polar bears. The localities of only seven former breeding colonies are known: Papa Westray in the Orkney Islands, St. Kilda off Scotland, Grimsey Island, Eldey Island, Geirfuglasker near Iceland, Funk Island near Newfoundland, and the Bird Rocks (Rochers-aux-Oiseaux) in the Gulf of St. Lawrence. Records suggest that this species may have bred on Cape Cod in Massachusetts. By the late eighteenth and early nineteenth centuries, the breeding range of the great auk was restricted to Funk Island, Grimsey Island, Eldey Island, the Gulf of St. Lawrence, and St. Kilda Island. Funk Island was the largest known breeding colony. After the chicks fledged, the great auk migrated north and south away from the breeding colonies and they tended to go southward during late autumn and winter.
It also was common on the Grand Banks of Newfoundland. In recorded history, the great auk typically did not go farther south than Massachusetts Bay in the winter. Archeological excavations have found great auk remains in New England and Southern Spain. Great auk bones have been found as far south as Florida, where it may have been present during four periods: approximately 1000 BC and 1000 AD, as well as, during the fifteenth century and the seventeenth century. (It has been suggested that some of the bones discovered in Florida may be the result of aboriginal trading.) Pleistocene fossils indicate the great auk also inhabited Southern France, Italy, and other coasts of the Mediterranean basin.
The great auk was never observed and described by modern scientists during its existence and is only known from the accounts of laymen, such as sailors, so its behaviour is not well known and difficult to reconstruct. Much may be inferred from its close, living relative, the razorbill, as well as from remaining soft tissue.
Great auks walked slowly and sometimes used their wings to help them traverse rough terrain. When they did run, it was awkwardly and with short steps in a straight line. They had few natural predators, mainly large marine mammals, such as the orca and white-tailed eagles. Polar bears preyed on nesting colonies of the great auk. Reportedly, this species had no innate fear of human beings, and their flightlessness and awkwardness on land compounded their vulnerability. Humans preyed upon them as food, for feathers, and as specimens for museums and private collections. Great auks reacted to noises, but were rarely frightened by the sight of something. They used their bills aggressively both in the dense nesting sites and when threatened or captured by humans. These birds are believed to have had a life span of approximately 20 to 25 years. During the winter, the great auk migrated south, either in pairs or in small groups, but never with the entire nesting colony.
The great auk was generally an excellent swimmer, using its wings to propel itself underwater. While swimming, the head was held up but the neck was drawn in. This species was capable of banking, veering, and turning underwater. The great auk was known to dive to depths of 76 metres (249 ft) and it has been claimed that the species was able to dive to depths of 1 kilometre (3,300 ft). To conserve energy, most dives were shallow. It also could hold its breath for 15 minutes, longer than a seal. Its ability to dive this deeply reduced competition with other alcid species. The great auk was capable of accelerating underwater, then shooting out of the water to land on a rocky ledge above the ocean's surface.
This alcid typically fed in shoaling waters that were shallower than those frequented by other alcids, although after the breeding season, they had been sighted as far as 500 kilometres (310 mi) from land. They are believed to have fed cooperatively in flocks. Their main food was fish, usually 12 to 20 centimetres (4.7 to 7.9 in) in length and weighing 40 to 50 grams (1.4 to 1.8 oz), but occasionally their prey was up to half the bird's own length. Based on remains associated with great auk bones found on Funk Island and on ecological and morphological considerations, it seems that Atlantic menhaden and capelin were their favoured prey. Other fish suggested as potential prey include lumpsuckers, shorthorn sculpins, cod, sand lance, as well as crustaceans. The young of the great auk are believed to have eaten plankton and, possibly, fish and crustaceans regurgitated by adults.
Historical descriptions of the great auk breeding behaviour are somewhat unreliable. Great Auks began pairing in early and mid-May. They are believed to have mated for life (although some theorize that great auks could have mated outside their pair, a trait seen in the razorbill). Once paired, they nested at the base of cliffs in colonies, likely where they copulated. Mated pairs had a social display in which they bobbed their heads and displayed their white eye patch, bill markings, and yellow mouth. These colonies were extremely crowded and dense, with some estimates stating that there was a nesting great auk for every 1 square metre (11 sq ft) of land. These colonies were very social. When the colonies included other species of alcid, the great auks were dominant due to their size.
Female great auks would lay only one egg each year, between late May and early June, although they could lay a replacement egg if the first one was lost. In years when there was a shortage of food, the great auks did not breed. A single egg was laid on bare ground up to 100 metres (330 ft) from shore. The egg was ovate and elongate in shape, and it averaged 12.4 centimetres (4.9 in) in length and 7.6 centimetres (3.0 in) across at the widest point. The egg was yellowish white to light ochre with a varying pattern of black, brown, or greyish spots and lines that often were congregated on the large end. It is believed that the variation in the egg streaks enabled the parents to recognize their egg among those in the vast colony. The pair took turns incubating the egg in an upright position for the 39 to 44 days before the egg hatched, typically in June, although eggs could be present at the colonies as late as August.
The parents also took turns feeding their chick. According to one account, the chick was covered with grey down. The young bird took only two or three weeks to mature enough to abandon the nest and land for the water, typically around the middle of July. The parents cared for their young after they fledged, and adults would be seen swimming with their young perched on their backs. Great auks matured sexually when they were four to seven years old.
The great auk was a food source for Neanderthals more than 100,000 years ago, as evidenced by well-cleaned bones found by their campfires. Images believed to depict the great auk also were carved into the walls of the El Pendo Cave in Camargo, Spain and Paglicci, Italy more than 35,000 years ago, and cave paintings 20,000 years old have been found in France's Grotte Cosquer.
Native Americans valued the great auk as a food source during the winter and as an important cultural symbol. Images of the great auk have been found in bone necklaces. A person buried at the Maritime Archaic site at Port au Choix, Newfoundland, dating to about 2000 BC, was found surrounded by more than 200 great auk beaks, which are believed to have been part of a suit made from their skins, with the heads left attached as decoration. Nearly half of the bird bones found in graves at this site were of the great auk, suggesting that it had great cultural significance for the Maritime Archaic people. The extinct Beothuks of Newfoundland made pudding out of the eggs of the great auk. The Dorset Eskimos also hunted it. The Saqqaq in Greenland overhunted the species, causing a local reduction in range.
This species is estimated to have had a maximum population in the millions. The great auk was hunted on a significant scale for food, eggs, and its down feathers from at least the eighth century. Prior to that, hunting by local natives may be documented from Late Stone Age Scandinavia and eastern North America, as well as from early fifth century Labrador, where the bird seems to have occurred only as stragglers. Early explorers, including Jacques Cartier, and numerous ships attempting to find gold on Baffin Island were not provisioned with food for the journey home, and therefore, used this vulnerable species as both a convenient food source and bait for fishing. Reportedly, some of the later vessels anchored next to a colony and ran out planks to the land. The sailors then herded hundreds of these great auks onto the ships, where they were slaughtered. Some authors have questioned the reports of this hunting method and whether it was successful. Great auk eggs were also a valued food source, as the eggs were three times the size of a murre's and had a large yolk. These sailors also introduced rats onto the islands, that preyed upon nests.
The Little Ice Age may have reduced the population of the great auk by exposing more of their breeding islands to predation by polar bears, but massive exploitation by humans for their down drastically reduced the population. By the mid-sixteenth century, the nesting colonies along the European side of the Atlantic were nearly all eliminated by humans killing this bird for its down, which was used to make pillows. In 1553, the great auk received its first official protection, and in 1794 Great Britain banned the killing of this species for its feathers. In St. John's, those violating a 1775 law banning hunting the great auk for its feathers or eggs were publicly flogged, though hunting for use as fishing bait was still permitted. On the North American side, eider down initially was preferred, but once the eiders were nearly driven to extinction in the 1770s, down collectors switched to the great auk at the same time that hunting for food, fishing bait, and oil decreased.
The great auk had disappeared from Funk Island by 1800. An account by Aaron Thomas of HMS Boston from 1794 described how the bird had been slaughtered systematically until then:
If you come for their Feathers you do not give yourself the trouble of killing them, but lay hold of one and pluck the best of the Feathers. You then turn the poor Penguin adrift, with his skin half naked and torn off, to perish at his leasure. This is not a very humane method but it is the common practize. While you abide on this island you are in the constant practize of horrid cruelties for you not only skin them Alive, but you burn them Alive also to cook their Bodies with. You take a kettle with you into which you put a Penguin or two, you kindle a fire under it, and this fire is absolutely made of the unfortunate Penguins themselves. Their bodies being oily soon produce a Flame; there is no wood on the island.
With its increasing rarity, specimens of the great auk and its eggs became collectible and highly prized by rich Europeans, and the loss of a large number of its eggs to collection contributed to the demise of the species. Eggers, individuals who visited the nesting sites of the great auk to collect their eggs, quickly realized that the birds did not all lay their eggs on the same day, so they could make return visits to the same breeding colony. Eggers only collected the eggs without embryos and typically, discarded the eggs with embryos growing inside of them.
On the islet of Stac an Armin, St. Kilda, Scotland, in July 1840, the last great auk seen in Britain was caught and killed. Three men from St. Kilda caught a single "garefowl", noticing its little wings and the large white spot on its head. They tied it up and kept it alive for three days, until a large storm arose. Believing that the bird was a witch and was causing the storm, they then killed it by beating it with a stick.
The last colony of great auks lived on Geirfuglasker (the "Great Auk Rock") off Iceland. This islet was a volcanic rock surrounded by cliffs that made it inaccessible to humans, but in 1830, the islet submerged after a volcanic eruption, and the birds moved to the nearby island of Eldey, which was accessible from a single side. When the colony initially was discovered in 1835, nearly fifty birds were present. Museums, desiring the skins of the great auk for preservation and display, quickly began collecting birds from the colony. The last pair, found incubating an egg, was killed there on 3 June 1844, on request from a merchant who wanted specimens, with Jón Brandsson and Sigurður Ísleifsson strangling the adults and Ketill Ketilsson smashing the egg with his boot.[b]
The rocks were covered with blackbirds [referring to Guillemots] and there were the Geirfugles ... They walked slowly. Jón Brandsson crept up with his arms open. The bird that Jón got went into a corner but [mine] was going to the edge of the cliff. It walked like a man ... but moved its feet quickly. [I] caught it close to the edge – a precipice many fathoms deep. Its wings lay close to the sides – not hanging out. I took him by the neck and he flapped his wings. He made no cry. I strangled him.
There is an ongoing discussion on the internet about the possibilities for recreating the Great Auk using its DNA from specimens collected. This possibility is the subject of concern to science.
Today, 78 skins of the great auk remain, mostly in museum collections, along with approximately 75 eggs and 24 complete skeletons. All but four of the surviving skins are in summer plumage, and only two of these are immature. No hatchling specimens exist. Each egg and skin has been assigned a number by specialists. Although thousands of isolated bones were collected from nineteenth century Funk Island to Neolithic middens, only a few complete skeletons exist. Natural mummies also are known from Funk Island, and the eyes and internal organs of the last two birds from 1844 are stored in the Zoological Museum, Copenhagen. The whereabouts of the skins from the last two individuals has been unknown for more than a hundred years, but that mystery has been partly resolved using DNA extracted from the organs of the last individuals and the skins of the candidate specimens suggested by Errol Fuller  (those in Übersee-Museum Bremen, Royal Belgian Institute of Natural Sciences, Zoological Museum of Kiel University, Los Angeles County Museum of Natural History, and Landesmuseum Natur und Mensch Oldenburg). A positive match was found between the organs from the male individual and the skin now in the RBINS in Brussels. No match was found between the female organs and a specimen from Fuller's list, but authors speculate that the skin in Cincinnati museum of Natural History and Science may be a potential candidate due to a common history with the L.A. specimen.
Following the bird's extinction, remains of the great auk increased dramatically in value, and auctions of specimens created intense interest in Victorian Britain, where 15 specimens are now located, the largest number of any country. A specimen was bought in 1971 by the Icelandic Museum of National History for £9000, which placed it in the Guinness Book of Records as the most expensive stuffed bird ever sold. The price of its eggs sometimes reached up to 11 times the amount earned by a skilled worker in a year. The present whereabouts of six of the eggs are unknown. Several other eggs have been destroyed accidentally. Two mounted skins were destroyed in the twentieth century, one in the Mainz Museum during the Second World War, and one in the Museu Bocage, Lisbon that was destroyed by a fire in 1978.
The great auk is one of the more frequently referenced extinct birds in literature, much as the famous dodo. It appears in many works of children's literature.
The great auk also is present in a wide variety of other works of fiction.
In the short story The Harbor-Master by Robert W. Chambers, the discovery and attempted recovery of the last known pair of great auks is central to the plot (which also involves a proto-Lovecraftian element of suspense). The story first appeared in Ainslee's Magazine (August 1889) and was slightly revised to become the first five chapters of Chambers' episodic novel In Search of the Unknown, (Harper and Brothers Publishers, New York, 1904).
In his novel Ulysses, James Joyce mentions the bird while the novel's main character is drifting into sleep. He associates the great auk with the mythical roc as a method of formally returning the main character to a sleepy land of fantasy and memory.
Penguin Island, a 1908 French satirical novel by the Nobel Prize winning author Anatole France, narrates the fictional history of a great auk population that is mistakenly baptized by a nearsighted missionary.
The great auk is the subject of The Last Great Auk, a novel by Allen Eckert, which tells of the events leading to the extinction of the great auk as seen from the perspective of the last one alive. It appears also in Farley Mowat's Sea of Slaughter.
Ogden Nash warns that humans could suffer the same fate as the great auk in his short poem "A Caution to Everybody."
Night of the Auk, a 1956 Broadway drama by Arch Oboler, depicts a group of astronauts returning from the moon to discover that a full-blown nuclear war has broken out. Obeler draws a parallel between the human-caused extinction of the Great Auk and of the story's nuclear extinction of humankind.
This bird also is featured in a variety of other media.
The great auk was formerly the mascot of the Lindsay Frost campus of Sir Sandford Fleming College in Ontario. In 2012, the two separate sports programs of Fleming College were combined and the great auk mascot went extinct. The Lindsay Frost campus student owned bar, student center, and lounge is still known as the Auk's Lodge.
A cigarette company, the British Great Auk Cigarettes, was named after this bird.
Whalers wrote about woggins all the time. What in the world were they?
