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. 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 color morphs: a light one, with white head and body and gray wings and tail, and a dark one which is uniformly gray. Though similar in appearance to gulls, fulmars are in fact members of the Procellariidae family, which include petrels and shearwaters.
