The Atlantic puffin, also known as the common puffin, is a species of seabird in the auk family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin, are found in the northeastern Pacific. The Atlantic puffin breeds in Québec, Iceland, Norway, Greenland, Newfoundland and Labrador, Nova Scotia and the Faroe Islands, and as far south as Maine in the west and parts of Great Britain in the east. The Atlantic Puffin is most commonly found on the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds mainly on small fish, which it catches by diving under water, using its wings for propulsion.
