The northern fulmar, Arctic fulmar, or simply fulmar (Fulmarus glacialis) is an abundant seabird found primarily in subarctic regions of the North Atlantic and North Pacific oceans. There has been one confirmed sighting in the Southern Hemisphere, with a single bird seen south of New Zealand. Fulmars come in one of two colour morphs; a light one in temperate populations, with white head and body and grey wings and tail, and a dark one in arctic populations, which is uniformly grey; intermediate birds are common. Though similar in appearance to gulls, fulmars are in fact members of the family Procellariidae, which includes petrels and shearwaters. The northern fulmar and its sister species, the southern fulmar (Fulmarus glacialoides), are the only extant members of the genus Fulmarus.
