Species

The fulmars are tubenosed seabirds of the

extant species and two extinct fossil species from the Miocene
.

Fulmars superficially resemble gulls, but are readily distinguished by their flight on stiff wings, and their tube noses. They breed on

pelagic, feeding on fish, squid and shrimp
in the open ocean. They are long-lived for birds, living for up to 40 years.

Historically, the northern fulmar lived on the

Isle of St Kilda
, where it was extensively hunted. The species has expanded its breeding range southwards to the coasts of England and northern France.

Taxonomy

The genus Fulmarus was introduced in 1826 by the English naturalist James Stephens.[1] The name comes from the Old Norse Fúlmár meaning "foul-mew" or "foul-gull" because of the birds' habit of ejecting a foul-smelling oil.[2] The type species was designated by George Gray in 1855 as the northern fulmar .[3][4]

As members of

triglycerides that is stored in the proventriculus. This can be sprayed out of their mouths as a defence against predators and as an energy rich food source for chicks and for the adults during their long flights.[5] It will mat the plumage of avian predators, which can lead to their death. Fulmars have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of ocean water that they imbibe. It excretes a strong saline solution from their nose.[6]

Fossils

Two prehistoric species have been described from

Pacific coast of California: Fulmarus miocaenus (Temblor Formation) and Fulmarus hammeri from the Miocene.[8]

Description

The two fulmars are closely related

birds look superficially like gulls, but are not closely related, and are in fact petrels. The northern species is grey and white with a yellow bill, 43 to 52 cm (17–20 in) in length with a 102 to 112 cm (40–44 in) wingspan.[9]
The southern form is a paler bird with dark wing tips, 45 to 50 cm (18–20 in) long, with a 115 to 120 cm (45–47 in) wingspan.

Behavior

Breeding

A northern fulmar in flight

Both recent species breed on

nocturnal breeders, nor do they use burrows
; their eggs are laid on the bare rock or in shallow depressions lined with plant material.

In Britain, northern fulmars historically bred on

St. Kilda (where their harvesting for oil, feathers and meat was central to the islands' economy). They spread into northern Scotland in the 19th century, and to the rest of the United Kingdom by 1930. The expansion has continued further south; the fulmar can now often be seen in the English Channel and in France along the northern and western coasts, with breeding pairs or small colonies in Nord, Picardy, Normandy and along the Atlantic coast in Brittany.[10]

Feeding

Fulmars are highly

pelagic outside the breeding season, like most tubenoses, feeding on fish, small squid, shrimp, crustaceans, marine worms, and carrion.[11] The range of these species increased greatly in the 20th century due to the availability of fish offal from commercial fleets, but may contract because of less food from this source and climatic change.[9] The population increase has been especially notable in the British Isles.[12]

Like other

gulls. They look bull-necked compared to gulls, and have short stubby bills. They are long-lived, the longest recorded lifespan for F. glacialis being 40 years, 10 months and 16 days.[13]

Relationship with humans

Fulmars have for centuries been hunted for food. The engraver

duck eggs in taste and nourishment.[16] However, when the human population left St Kilda in 1930, the fulmar population did not suddenly increase.[17]

Both the southern fulmar and the northern fulmar are listed as of Least Concern by the International Union for Conservation of Nature (IUCN).[18][19]
