Pinguinus impennis (great auk)

Pinguinus impennis the great auk or garefowl, is the 'penguin of the north'. Pinguinus impennis is the only flightless auk.

The great auk ranged from Canada to Norway, including Newfoundland, Greenland, Iceland, the United Kingdom and Ireland.

Hunting was responsible for the decline and eventual extinction of the great auk. The last great auk hunt took place on 3rd June 1844, on Eldey Island off southwestern Iceland, when a breeding pair was thoughtlessly slaughtered.

Behaviour

The great auk foraged in shallow waters eating fish, crabs and plankton.

The great auk only ever came ashore in rocky offshore islands to breed. Each pair laid a single egg on bare rock.

They migrated south in the winter, and bones have been found as far south as Florida and Gibraltar.
