Appearance
The Fulmar is a robust seabird with a stocky body and thick neck. Its plumage is predominantly grey above and white below, with a pale blue-grey tinge on the wings. The bird has a distinctive tube-shaped nostril on top of its yellow, hooked bill.
Females and males are virtually identical, although males may be marginally heavier than females. Juveniles resemble adults but may have slightly darker colouration on their wings and back.
In flight, fulmars are relatively easy to identify, gliding and banking close to the ocean surface with stiff, outstretched wings. From a distance, they resemble shearwaters, but up close, they can be distinguished by their wing size and flight style.

Attributes
Understanding Attributes
Rated 0–100 based on research and observation. A score of 50 is average across all bird species. These attributes are relative and don't necessarily indicate superiority.
Habitat & Distribution
Fulmars inhabit the North Atlantic and North Pacific oceans, breeding on coastal cliffs and rocky islands. They are found in subarctic and temperate regions, with significant populations in Iceland, Norway, and the British Isles.
During non-breeding seasons, Fulmars disperse widely across open oceans. In North America, they can be observed along the coasts of Alaska and Canada, while in Europe, they're common around the UK and Ireland.
The UK’s fulmar breeding colonies are concentrated on Scotland’s Northern Isles and along its north coast. Hirta, Dun, Soay and Stacs in the St Kilda archipelago are leading breeding grounds, with further sizeable populations on Foula and Fair Isle in the Shetland Islands.
North American fulmar-spotting sites include Andrews Point (Cape Ann) and Race Point (Cape Cod), Massachusetts. Breeding colonies are naturally established in isolated regions and the best chance of seeing fulmars is when the birds feed over coastal areas.

Diet
Fulmars are opportunistic feeders, primarily consuming small fish, squid, and plankton. They also scavenge for offal and discards from fishing vessels.
Birds have also been seen eating remains of seals, whales, walruses and even other seabirds. Fulmars catch their prey on or just below the ocean surface.
These birds have a unique ability to filter seawater through their bills to extract food particles, allowing them to feed on the ocean's surface.
Behaviour
Fulmars are excellent gliders, often seen soaring effortlessly over waves with stiff, straight wings. They are highly pelagic, spending most of their lives at sea.
These birds are known for their unique defence mechanism of spitting out a foul-smelling oil when threatened, which can matte the feathers of potential predators.
Calls & Sounds
Fulmars are generally quiet at sea but become more vocal at breeding colonies. Their calls include a series of guttural cackles and growls, often described as 'ak-ak-ak' or 'koka-koka'. During courtship, pairs produce softer, purring sounds when greeting each other at the nest site.
Nesting & Breeding
Fulmars form long-term pair bonds and typically breed from May to September. They nest on cliff ledges or steep grassy slopes, often returning to the same site year after year.
The female lays a single white egg directly on the bare rock or in a shallow scrape. Both parents share incubation duties, which last about 50 days.
Chicks are covered in grey down when hatched and remain in the nest for about 50 days before fledging. Parents continue to feed the chick for several weeks after it leaves the nest.
Conservation
While currently listed as Least Concern, Fulmars face threats from plastic pollution and oil spills. They often ingest plastic debris, mistaking it for food. Conservation efforts focus on reducing marine pollution and protecting breeding sites on coastal cliffs.

Sea level to 300 meters
Additional Details
- Predators:
- Adult Fulmars have few natural predators due to their defensive oil-spitting behavior. However, eggs and chicks may fall prey to large gulls, skuas, and occasionally foxes or rats at accessible nest sites.
Birdwatching Tips
- Look for Fulmars gliding low over the sea with stiff wings
- Observe coastal cliffs during the breeding season for nesting birds
- Note the distinctive tube-shaped nostril on the bill
- Watch for their habit of following fishing boats for discards
- In the UK, check popular sites like Bempton Cliffs or Orkney Islands
Did You Know?
- Fulmars can live for over 50 years, making them one of the longest-lived seabirds.
- Their name comes from Old Norse, meaning 'foul gull', referring to their oily stomach contents.
- Fulmars can drink seawater and excrete excess salt through special glands above their eyes.
