' Great Auk Stack '), [2] or Freykja (), [citation needed] is a small, uninhabited island in the Vestmannaeyjar archipelago. [1] [2] Geirfuglasker is located approximately 30 kilometres (19 mi) off Iceland's southwestern coast. [1] [2] The island hosted one of the last known colony of great auks, which thrived given its inaccessibility to humans.
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. [50] [19]: 329 The great auk had disappeared from Funk Island by 1800.
The rough surf around the island usually made it inaccessible to humans, and one of the last refuges for the flightless bird the great auk (which was also called "garefowl" — "geirfugl" in Icelandic). In a volcanic eruption in 1830 this rock submerged. The surviving great auks moved to a nearby island called Eldey and were wiped out by humans ...

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 (6 in) long, rendering the bird flightless. Instead, the great auk was a powerful swimmer, a trait that it used in hunting.
Historians and naturalists believe that the Penguin Islands were a former breeding ground for the great auk. [1] Petrels were reported nesting in the islands in 1887, with an estimated 900 pairs living on South Penguin Island in 1945. [1]
Fugloy was also a nesting site for the now extinct great auk (garefowl). On the east side of the island there is a rock ledge called Gorfuglarókin "Garefowl Ledge", and written sources confirm that great auks were still breeding on Fugloy in the 18th century.
By 1800 the great auk was probably extinct on Funk Island, and by 1844, in the world. Naturalists and scientists had become interested in the plight of the great auk and by June 1841 a Norwegian naturalist, Dr. Peter Stuvitz visited Funk Island with the hope of obtaining specimens of the birds, but was forced to leave due to weather conditions ...
