Atlantic puffin

Presentation

The Atlantic puffin is a small seabird recognizable by its triangular orange and gray streaked bill, which earned it the nickname “sea parrot”. It frequents the coasts and rocky islands of the North Atlantic, where it forms large nesting colonies. An excellent diver, it captures its prey underwater using its short wings which serve as fins. Outside of the breeding season, it spends most of its life on the high seas, far from the coast. Its stocky appearance and clumsy gait on the ground contrast with its remarkable agility in the water.

The Atlantic puffin measures approximately 28 to 30 cm long with a wingspan of 50 to 60 cm. Its plumage is black and white, with white cheeks and a massive bill colored red, yellow and blue-gray during the breeding season, which becomes duller in winter. Its bright orange webbed feet and red-rimmed eyes complete its distinctive appearance. The beak loses its colored patches after the breeding season, giving the bird a more discreet appearance.

Characteristics

Indicative values: they vary by subspecies, sex and region.

Habitat and distribution

The Atlantic puffin nests on coastal cliffs and rocky or grassy islands in the North Atlantic. It favors slopes of loose earth suitable for digging burrows. Outside of the breeding season, it lives exclusively in the open sea, sometimes far from any coast.

Behaviour

It is a gregarious bird that lives in dense colonies on cliffs and islands, often alongside other seabirds. It digs burrows in soft soil or uses rock cavities to nest, returning each year to the same site. Outside of breeding, it becomes largely solitary and pelagic, spending the winter at sea. Its flight is rapid but not very energy-efficient, with sustained wingbeats.

Reproduction

Atlantic puffin reaches sexual maturity around 4 to 5 years of age and forms generally faithful pairs over several seasons. The female lays a single egg at the bottom of a burrow dug in the earth or between rocks. Incubation lasts approximately 39 to 45 days, carried out by both parents alternately. The chick, called a “puffling”, leaves the nest at night to reach the sea alone, several weeks after hatching.

Peculiarities

The Atlantic puffin's colorful bill changes appearance with the seasons, losing its outer plates after breeding. The bird can beat its wings up to 400 times per minute in flight. Its ability to line up several small fish in its beak when fishing is a remarkable anatomical feature.

Threats and conservation

Major threats include climate change, which affects the availability of prey fish, as well as marine pollution and oil spills. Predation by introduced species on certain nesting islands and overfishing of the fish on which it depends also weighs on populations. Some historic settlements have experienced marked decline in recent decades.
