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.
' 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.
Like the great auk, P. alfrednewtoni was a flightless wing-propelled diver, meaning that they used their wings to propel themselves forward underwater in a fashion similar to penguins. While this locomotion is used by both flying and flightless auks, Smith suggests that the body weight limit for volant alcids lies at 2–2.5 kg (4.4–5.5 lb ...

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 ...

The family contains 25 extant or recently extinct species that are divided into 11 genera. Auks are found throughout the Northern Hemisphere. [1] [2] Apart from the extinct great auk, all auks can fly, and are excellent swimmers and divers (appearing to "fly" in water), but their walking appears clumsy.
