Auks are birds of the family Alcidae in the order Charadriiformes. They are superficially similar to penguins due to their black-and-white colours, their upright posture and some of their habits. Nevertheless they are not related to the penguins at all.
In contrast to penguins, auks are able to fly (with the exception of the Great Auk). They are good swimmers and divers, but their way of walking appears clumsy. Due to their short wingspan auks have to flap their wings very fast in order to fly.
Auks live on the open sea. Only for breeding do they go ashore. Most species breed at steep cliffs, often together with gulls, petrels and gannets.
