The Great Auk, *Pinguinus impennis*, was an iconic flightless seabird of the North Atlantic, a poignant symbol of human-induced extinction. Standing approximately 75-85 cm tall and weighing around 5 kg, this large alcid was characterized by its sleek, jet-black back, head, and throat contrasting sharply with a pure white belly and flanks. Its most distinctive field mark was a prominent, oval-shaped white patch situated in front of each eye, particularly noticeable in breeding plumage. Taxonom...
Primarily a marine species, the Great Auk inhabited frigid North Atlantic waters, congregating on remote, rocky, low-lying offshore islands and skerries for breeding.
The Great Auk was a specialized piscivore, feeding primarily on small-to-medium-sized fish such as capelin, sand eels, and Atlantic cod, supplemented with crustaceans. It used pursuit diving to capture prey far beneath the surface.
Great Auks were colonial breeders, congregating in large numbers on isolated islands to lay their single egg directly on bare rock or sparse vegetation. Monogamous pair bonds were likely formed, with both parents sharing incubation duties and parental care for the chick. At sea, they were highly ...
Historically, the Great Auk's breeding range spanned across several remote, rocky islands and skerries in the North Atlantic. Key breeding colonies were found on Funk Island off Newfoundland, St Kilda in Scotland, the Faroe Islands, Grimsey and Eldey Island off Iceland, and possibly on certain is...
