They spend most of their lives at sea, comming ashore only to breed. They nest in dense colonies on steep cliffs to reduce the risk of predation of eggs and young.

They are most at home in the water, diving for fish. Some subspecies have dark chocolate brown plumage and some have black, both with white fronts. Juveniles have white cheeks and chins. A "bridled" form has white eye rings and a white streak from the eye looking like a pair of spectacles.

Auks fill the "penguin" niche in the northern oceans. However they have wings rather than flippers and can (and do) fly.
