s. 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 six weeks before the young hatched. The young left the nest site after two to three 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 auks' skins.

Around the same time, nations such as Great Britain began to realize that the great auk was disappearing and it became the beneficiary of many early environmental laws, but despite that the great auk were still hunted. 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 report 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 Ornithological Society was named ''

During the summer, 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 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

. 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 the St. Kilda islands. 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.

Ecology and behaviour

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

, 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

, and white-tailed eagles. Polar bears preyed on nesting colonies of the great auk. Based on observations by the Naturalist Otto Fabricius (the only scientist to make primary observations on the great auk), some auks were "stupid and tame" whilst others were difficult to approach which he suggested was related to the bird's age. 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 and it has been claimed that the species was able to dive to depths of . To conserve energy, most dives were shallow. It also could hold its breath for 15 minutes, longer than a seal. Its ability to dive so 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.

Diet

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 from land. They are believed to have fed cooperatively in flocks. Their main food was fish, usually in length and weighing , 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

Reproduction

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 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 from shore. The egg was ovate and elongate in shape, and it averaged in length and 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.

Relationship with humans

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,

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, with recent evidence indicating the latter alone is likely the primary driver of its extinction. 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. 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: Eldey close

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 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. Grote alk -KBIN-

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 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. Jón Brandsson and Sigurður Ísleifsson, the men who had killed the last birds, were interviewed by great auk specialist John Wolley, and Sigurður described the act as follows: A later claim of a live individual sighted in 1852 on the

has been accepted by the International Union for Conservation of Nature and Natural Resources. Alleged sightings of the auk continued for decades after it was believed extinct. The last alleged sighting occurred in the Lofotens in 1927. Errol Fuller noted that several of the later sightings were hoaxes or misidentifications of penguins that had been released near Norway. There is an ongoing discussion about the possibilities for reviving the great auk using its DNA from specimens collected. This possibility is controversial.

Preserved specimens

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

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.

Kingsley's auk implicates the "nasty fellows" who "shot us so, and knocked us on the head, and took our eggs." While Kingsley portrays the extinction as sad, he provides his opinion that "there are better things come in her place," namely human colonization of the islands for the
