On Infinity, the Great Auk fears humans more than almost any other creature. Great Auks were excellent swimmers, using their wings to swim underwater. Their main food was fish. They had few natural enemies, besides perhaps polar bears, and had no natural fear of humans. Their flightlessness and awkwardness meant they were easy prey for humans, who hunted them for food, feathers, and also for museums and private collections. Great Auks, found incubating an egg, were killed on 3rd July 1844, on the Island of Eldey, near Iceland.

Hunted for food, and by collectors, for their feathers and eggs. Some people thought the Great Auk looked like a witch, so they killed it for the sake of it.
