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
Iceland,
Norway,
Greenland,
Newfoundland and many North Atlantic islands, and as far south as
Maine in the west and the
British Isles in the east. With a large population and a wide range, the species is not considered to be endangered, although there may be local declines in numbers. 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 underwater, using its wings for propulsion.
