Fulmars (Fulmarus Glacialis)
January 29, 2013 by staff
Fulmars (Fulmarus Glacialis), The Northern Fulmar, Fulmarus glacialis, Fulmar, or Arctic Fulmar is a highly abundant sea bird found primarily in subarctic regions of the north Atlantic and north Pacific oceans. Fulmars come in one of two color morphs: a light one which is almost entirely white, and a dark one which is uniformly grey.
Though similar in appearance to gulls, fulmars are in fact members of the Procellariidae family, which include petrels and shearwaters. It and the Southern Fulmar (Fulmarus glacialodes) together comprise the only extant species in the genus Fulmarus.
The Northern Fulmar and its sister, the Southern Fulmar, are the extant members of the genus Fulmarus. The fulmars are in turn a member of the order Procellariiformes, and they all share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns; however, nostrils on albatrosses are on the sides of the bill, as opposed to the rest of the order, including fulmars, which have nostrils on top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates.
One of these plates makes up the hooked portion of the upper bill, called the maxillary unguis. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy rich food source for chicks and for the adults during their long flights.
The Northern Fulmar was first described as Fulmarus glacialis by Carl Linnaeus, in 1761, based on a specimen from within the Arctic Circle, on Spitsbergen.
