Meet the Atlantic Puffin

With its bold orange-and-yellow bill, black-and-white plumage, and almost comical waddling gait on land, the Atlantic Puffin (Fratercula arctica) is one of the most instantly recognizable seabirds in the Northern Hemisphere. Often called the "clown of the sea," this compact bird leads a surprisingly remarkable life split between windswept clifftop colonies and the open ocean.

Physical Description

Atlantic Puffins are small auks, typically around 28–30 cm in length. Their most striking feature is the large, brightly coloured triangular bill, which develops its vivid orange-red, yellow, and grey colouring during the breeding season. Outside of breeding, the bill becomes duller and smaller as the outer sheath is shed — a fact that surprises many birdwatchers who only know them from summer photos.

  • Length: 28–30 cm
  • Wingspan: 47–63 cm
  • Weight: 320–550 g
  • Lifespan: Up to 20–25 years in the wild

Range and Habitat

Atlantic Puffins breed along the coasts of the North Atlantic Ocean, from Newfoundland and Maine in the west to Iceland, Norway, the British Isles, and as far south as the Canary Islands in the east. Iceland hosts the largest breeding colony, accounting for a significant proportion of the world's puffin population.

During winter, puffins disperse far out to sea, spending months on the open ocean, rarely coming ashore. Their at-sea range extends across the North Atlantic, often venturing far from land.

Behaviour and Diet

Puffins are extraordinary divers, using their wings to "fly" underwater in pursuit of small fish such as sand eels, sprats, and herring. They are capable of diving to depths of around 60 metres and can hold multiple fish crosswise in their bill — sometimes carrying a dozen or more at once thanks to a unique hinge and spiny tongue that holds fish in place.

On land, their flight appears laboured and fast-beating, requiring up to 400 wingbeats per minute to stay airborne — but in the water, they are swift and highly manoeuvrable.

Breeding

Puffins are monogamous and typically return to the same burrow — and the same mate — year after year. Colonies form on grassy clifftops and rocky islands, where birds excavate or reuse burrows up to 90 cm deep. A single egg is laid each season, and both parents share incubation duties over approximately 39–45 days. The chick, called a "puffling," is fed by both parents until it fledges at around 6 weeks old.

Conservation Status

The Atlantic Puffin is currently listed as Vulnerable on the IUCN Red List. Populations have declined significantly in parts of their range, driven by reduced fish availability (linked to climate change and industrial fishing), predation by introduced mammals on nesting islands, and pollution at sea. Conservation efforts include predator removal from key nesting islands and ongoing monitoring programs.

Where to Watch Them

  • Skomer Island, Wales (UK) — One of the UK's most accessible puffin colonies
  • Látrabjarg, Iceland — A towering clifftop hosting thousands of breeding birds
  • Seal Island, Maine (USA) — Restored puffin colony managed by Project Puffin
  • Runde, Norway — A major Norwegian breeding site

The best time to visit is late April through early August, when adults are present at colonies and activity is at its peak.

A Bird Worth Knowing

The Atlantic Puffin captures the imagination like few other birds. Its seemingly mismatched combination of features — elegant at sea, awkward on land, comical in expression — belies a resilient animal perfectly adapted to one of the harshest environments on Earth. If you ever get the chance to sit near a puffin colony on a summer evening, watching hundreds of birds wheel in from the sea, it is an experience that stays with you for life.
