The Atlantic Puffin (Fratercula arctica), also known as the Sea Parrot or Calculot , is a species of North Atlantic pelagic seabird that lives on the high seas, except when breeding, when it must return to land, where it nests on grassy slopes, islands or cliffs (insular or continental). This species lives only in the North Atlantic. It is the only Atlantic species of puffin, the other three being found only in the Pacific. Its range was probably wider in prehistoric times; today it breeds only locally on the isolated coasts of northern Europe, Iceland and eastern North America.
In North America, it nests from Canada (near the Îles de la Madeleine on the Oiseaux rocks and on the Mingan archipelago) to the North Shore in Quebec (Canada). A colony of 21,000 individuals (according to a 2013 count[5]) has been recorded on the Saint-Pierre and Miquelon archipelago, particularly on Grand Colombier Island. In Europe, the largest colonies are found in Iceland (2 to 3 million pairs), with smaller populations in Ireland, Scotland, Shetland, Scandinavia, the Faroe Islands and Brittany.
