The Atlantic puffin (Fratercula arctica) is a seabird in the auk family that breeds on coastal islands and cliffs in the North Atlantic. It is known for its brightly coloured bill, burrowing nests, and ability to carry multiple fish at once. The species spends much of the year at sea and is listed as Vulnerable globally.

Description

The Atlantic puffin is a medium-sized seabird with a stocky body, black-and-white plumage, and a distinctive multicoloured bill. Its bill is especially vivid during the breeding season and is one of the bird’s best-known features.

Distribution and habitat

Atlantic puffins breed on islands and sea cliffs across the North Atlantic, including areas in Canada, Iceland, Greenland, Norway, the British Isles, and parts of the northeastern United States. Outside the breeding season, they live offshore on the open ocean.

Diet and feeding

Atlantic puffins feed mainly on small schooling fish and occasionally on crustaceans and other marine invertebrates. They can catch several fish in one dive and carry them back to chicks in their bill.

Breeding and life cycle

Puffins nest in burrows, usually on grassy or rocky ground near the sea. They are long-lived seabirds that return to land primarily to breed and raise their young.

Conservation

The Atlantic puffin is considered Vulnerable globally because populations are declining in several parts of its range. Food shortages, especially those linked to warming seas, are a major concern.

Key facts

  • Atlantic puffins eat mostly small fish such as sand lance, capelin, herring, sprat, and hake.
  • They nest in burrows on rocky islands and sea cliffs, and spend most of the year at sea.
  • Their bill has specialized features that let them hold several fish crosswise at once.
  • The species is globally listed as Vulnerable, with population declines linked mainly to changes in food supply.
  • Puffins are strong swimmers and divers; they use their wings for propulsion underwater and their feet for steering.

Canadian context

Atlantic puffins breed in Canada, especially in parts of Atlantic Canada, and are familiar seabirds to Canadian birdwatchers. Canadian conservation concerns include food availability and changes in ocean conditions that affect breeding success.

Frequently asked questions

What do puffins eat?
Atlantic puffins mainly eat small fish such as sand lance, capelin, herring, sprat, and hake. They sometimes also eat shrimp, other crustaceans, molluscs, and polychaete worms.
Where do puffins live?
Atlantic puffins live in the North Atlantic. They breed on rocky islands and sea cliffs and spend the rest of the year at sea.
How long do puffins live?
Atlantic puffins are long-lived seabirds, but an exact lifespan varies by source and individual. They can live for many years, with some seabirds reaching several decades.
Are puffins endangered?
The Atlantic puffin is not listed as Endangered globally; it is listed as Vulnerable on the IUCN Red List. Some regional populations are considered of lower conservation concern.
How do puffins fly?
Puffins fly by beating their wings rapidly. They are also strong swimmers, using their wings underwater for propulsion and their feet for steering.
Why do puffins have colorful beaks?
Their colourful bills are most noticeable during the breeding season and are used in visual signalling, especially in courtship. The bill’s colour is part of the species’ breeding plumage and changes outside that season.
