Physical description Click here for a physical description Northern Fulmars are medium-sized seabirds. Their colours can vary, although there are no distinctly different morphologies, from near-white body with light-grey upperparts (pale birds) to light- to mid-grey all over (dark birds). Pale Northern Fulmars have an almost all-white front, head, neck (with some pale grey on the sides) and large parts of the underwings. The upperwings, back and mantle are light-grey. The outer leading edge and the trailing edge of the underwing is dark. Dark Northern Fulmars are mid-grey all over their body and their wings. All morphologies have darker tips than the rest of the wings, with a diffuse pale patch on the upperside of the primaries. The irises are dark and the bill is rather short and massive, given more volume by their tube nose. The base of the bill is grey, while the tip is yellow. In pale birds the tube is light-grey, in dark birds it is near-black. Legs and feet are grey.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Northern Fulmar is available HERE . There are 3 races of Northern Fulmars, which are a strongly migratory species. The two races "glacialis" and "auduboni" are present in the North Atlantic, while race "rodgersii" in found in the North Pacific. We cannot distinguish between the two North-Atlantic races "glacialis" and "auduboni" and will group them into one conglomerate here. In Europe, Northern Fulmars, races "glacialis/auduboni", breed in the high Arctic regions of the Atlantic and the low Arctic and boreal regions of the Atlantic, respectively. They spend basically the entire non-breeding season at sea on the northern Atlantic. Northern Fulmars are found mostly on the open seas, but also in coastal waters and, during their breeding season, on coastlines and offshore islands, especially those with steep cliffs.

Sightings Click here for sighting information Race "glacialis/auduboni" M. Eaton reports spotting Northern Fulmars, races "glacialis/auduboni", at Land's End, Cornwall, England, in September 2019. Race "auduboni" C. Pears reports finding Northern Fulmars, race "auduboni", in Iceland in May 2015, where they were nesting at the time.
