The two Fulmars are closely related seabirds occupying the same niche in different oceans. The Northern Fulmar (Fulmarus glacialis), or just Fulmar lives in the north Atlantic and north Pacific, whereas the Southern Fulmar (F. glacialoides) is, as its name implies, a bird of the southern oceans. These birds look superficially like gulls, but are unrelated, and are in fact petrels.
Image:Southern Fulmar closeup.jpg Both species breed on cliffs, laying a single white egg. Unlike many small to medium birds in the Procellariiformes they are neither nocturnal breeders, nor do they use burrows. Nesting birds and chicks can eject an evil smelling stomach oil up to 2 m, which repels unwanted visitors. It will matt the plumage of avian predators, and can lead to their death.
They are highly pelagic outside the breeding season, like most tubenoses, feeding on fish, oil or offal. Recent studies in the North Sea have shown them especially susceptible to plastic discards.
Like other petrels, their walking ability is limited, but they are strong fliers, with a stiff wing action quite unlike the gulls. They look bull-necked compared to gulls, and have short stubby bills. They are long-lived, with a lifespan of 40 years not uncommon.
The northern species is grey and white, 43-52 cm in length with a 101-117 cm wingspan. The southern form is a paler bird with dark wing tips, 45-50 cm long, with a 115-120 cm wingspan.
The range of these species increased greatly last century due to the availability of fish offal from commercial fleets, but may contract because of less food from this source and climatic change.
Northern Fulmars historically bred on St. Kilda, and spread into northern Scotland in the 19th century, and to the rest of the United Kingdom by 1930.
The Sibley-Ahlquist taxonomy gives a radically different scientific arrangement for this group based on DNA studies.
