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.
It is the closest living relative of the extinct great auk (Pinguinus impennis). [4] Historically, it has also been known as "auk", [5] "razor-billed auk" [6] and "lesser auk". [7] Razorbills are primarily black with a white underside. The male and female are identical in plumage; however, males are generally larger than females.
Auks are pelagic birds, spending the majority of their adult lives on the open sea and going ashore only for breeding, although some species, such as the common guillemot, spend a great part of the year defending their nesting spot from others. Auks are monogamous, and tend to form lifelong pairs.
The great auk was a large flightless bird that lived in the Northern Hemisphere. It had a large, intricately grooved beak. When the first settlers arrived in Iceland, the auk population was probably in the millions. However, the settlers found the auks to be “very good and nourishing meat.”
A taxidermized Great Auk The great auk (or, as it has been nicknamed, the “Penguin of the North”) was a flightless marine bird that inhabited the North Atlantic Ocean and its nearby islands. Its range once extended to the continental United States and Europe. [ 21 ]

Great auks could range up to 6.8 kg (15 lb) and 0.9 m (3.0 ft) tall. [79] Miomancalla howardi was the largest charadriiform of all time, weighing approximately 1.5 ft (0.46 m)(?) more than the Great Auk with a height of approximately 1 m (3.3 ft). [80] The Saddle-billed stork is perhaps the tallest of the storks.
These species, together with the razorbill, little auk and the extinct great auk make up the tribe Alcini. This arrangement was originally based on analyses of auk morphology and ecology. [7] The official common name for this species is Common Murre according to the IOC World Bird List, Version 11.2.
