Birdlife of the Arctic
25 March 2026 | Arctic Circle, Wildlife
Home to approximately 280 bird species - including millions of nesting seabirds - the Arctic region attracts a host of feathered wonders. From the elegant Arctic Terns to the graceful Black-legged Kittiwakes and comical Puffins - birdlife is among the Arctic’s most dramatic natural spectacles.
Cliff Colonies
The Arctic is home to millions of migratory seabirds that breed in vast numbers on steep, protected cliff walls. These remote outcrops provide safe nesting grounds, inaccessible to terrestrial predators such as the wily Arctic foxes who prowl the slopes for fallen chicks or unguarded eggs. Abundant fish and plankton are foraged by seabirds in the icy waters below, sustaining the massive colonies and their hungry brood.
The Thick-billed Murre or Brünnich's Guillemot spends its life at sea, only coming ashore to nest on narrow, precarious cliff edges. These checkerboard-coloured seabirds have been known to breed in up to 60,000 pairs on the towering basalt walls at Alkefjellet, Svalbard's most iconic bird cliff – kilometers wide and rising 100 metres from sea level. Accessed by Zodiac boats, visitors to Alkefjellet have the perfect vantage point to view these raucous colonies as they continue the cycle of life in the Arctic’s delicately balanced ecosystem.
Black-legged Kittiwakes are also widespread across the Arctic, including Svalbard. These small, graceful gulls nest in teeming colonies on the islands of Hopen and Bjørnøya. Glaucous Gulls also breed on cliffs, rocky islands or slopes, building their nests from seaweed, moss, and grass. This large gull is a known predator, stealing eggs, chicks, and adult seabirds from nearby seabird colonies.
Birds Around Glaciers and Fjords
Birdlife is abundant in the Arctic’s ancient fjords and glaciers, such as Liefdefjorden in the Svalbard archipelago and Raudfjord, on the northwestern coast of Spitsbergen. During melts, glacier run-off stirs rich nutrients to the ocean surface, attracting fish and plankton and, in turn, providing nutritious meals for seabirds and their offspring.
Puffins inhabit Arctic fjords, developing their striking red beak during the summer months as a mating lure. Skilled swimmers, Puffins can dive up to 60 meters underwater in search of prey and fly at up to 88 kilometres an hour. Other species that thrive in the glacial ice include Arctic Tern, Ivory Gull, the King Eider, and Long-tailed Duck.
Tundra and Coastal Species
Beyond the cliffs, the tundra’s stark landscape is frozen for much of the year, allowing the Snowy Owls or Bubo Scandiaca to camouflage with the snow and ice. The tundra’s treeless landscape is covered by permafrost - a layer of permanently frozen ground – along with low shrubs, mosses, grasses, and lichens. This provides the ideal open hunting grounds for Snowy Owls, who locate prey with their laser eyesight and keen hearing. They are diurnal (active during the day), so are easier to spot than their nocturnal relatives.
The Snow Bunting also migrates to the Arctic to breed on rocky tundra, cliffs, and boulder fields, nesting in protected rock crevices. Svalbard’s Rock Ptarmigan is the only terrestrial bird that lives in the Arctic throughout the year, preferring high, rocky terrain and tundra areas. Listen out for its distinct cries, which have been compared to running a stick across a picket fence!
Coastal wetlands provide habitat for geese and waders during the fleeting summer season. Barnacle and Pink-footed Geese breed in Arctic regions and migrate to northern Europe for winter, nesting on grassy hummocks on the tundra, cliffs, and river gorges. Barnacle Geese are social and monogamous, while Pink-footed Geese fly in large flocks but are otherwise less social.
Delicate and sweet waders like the Bar-tailed Godwit, Dunlin, Curlew Sandpiper, and Grey Plover breed on the Arctic tundra, striding through the shallows on their long legs, feeding on invertebrates hidden in the mud.
Adaptations and Behaviour
The remarkable birds of the Arctic are experts at survival – relying on physical, behavioural, and instinctive behaviours that have been fine-tuned over millennia. Their adaptation to the cold and ice has allowed them to breed and flourish in a landscape defined by short, fertile summers and long, dark winters.
Millions of birds migrate across the oceans for the Arctic’s summer breeding season – using incredible stamina to cross hemispheres. The efficient Arctic Tern makes the longest trek – flying from the Antarctic to the Arctic to take advantage of abundant food sources and endless daylight hours. With the extension of sunlight, nocturnal predators have fewer chances to sneak up on prey, leaving more protection for nesting birds. An explosion of plant growth boosts insect and fish populations for plentiful feeding opportunities.
The Arctic’s migratory birds are a jaw-dropping sight, but they’re also critical to the success of the Arctic ecosystem: pollinating flowers, managing rodents and insects, and spreading vital organisms over long distances. Little Auks, for example, play a key role in Svalbard’s ecology by transporting marine nutrients to the land and fertilising the tundra with their guano (excrement).
Each Arctic bird species has found a delicate balance to respond to the most extreme environment on the planet.
