20-7-2025 ISAFJORDUR, ICELAND - NORTHERN FULMAR (Fulmarus glacialis)

The Northern Fulmar, or Fulmarus glacialis, is a robust seabird of the high subarctic seas. It is a member of the Procellariidae family, which includes petrels and shearwaters. This species exhibits two color morphs: the light morph, with a white head and body complemented by gray wings and tail, and the dark morph, which is uniformly gray. The Northern Fulmar has a wingspan of 102 to 112 cm and measures about 46 cm in length. It is characterized by a pale yellow, thick bill and bluish legs.

When observing the Northern Fulmar, look for its gray and white plumage, with the light morph being predominantly white with gray accents and the dark morph being uniformly gray. The bird's bill is pale yellow and stout, and its legs are a bluish hue. In flight, the Northern Fulmar exhibits a stiff wing action, distinct from the more fluid motion of gulls. It appears bull-necked and has a short, stubby bill.

The Northern Fulmar is found primarily in subarctic regions of the North Atlantic and North Pacific oceans. It nests on grassy ledges or on the ground, where it constructs a scrape or a saucer of vegetation lined with softer materials. In recent times, it has adapted to nesting on rooftops and buildings. 

This species is abundant across the North Atlantic and North Pacific, with a breeding range extending from the high Arctic regions to the low Arctic and boreal regions. It has been sighted as far south as New Zealand.

The Northern Fulmar is a strong flier, though its walking ability is limited. It is monogamous and forms long-term pair bonds, often returning to the same nest site annually. The bird starts breeding at six to twelve years old and is involved in nocturnal activities during the breeding season.

The Northern Fulmar produces a variety of sounds, including grunting and chuckling while feeding, and guttural calls during the breeding season.

Breeding begins in May, with both sexes participating in nest building. The Northern Fulmar lays a single white egg, which is incubated for 50 to 54 days. The altricial chick is brooded for two weeks and fully fledges after 70 to 75 days.

While similar in appearance to gulls, the Northern Fulmar is distinguished by its stouter build, shorter bill, and different flight pattern.

The diet of the Northern Fulmar includes shrimp, fish, squid, plankton, jellyfish, carrion, and refuse. It is capable of diving several feet deep to capture fish.

The IUCN lists the Northern Fulmar as Least Concern, with an estimated 15,000,000 to 30,000,000 mature individuals. The population is increasing, particularly in the British Isles, due to the availability of fish offal from commercial fleets.

The Northern Fulmar is an indicator species for marine debris. Studies have shown a high percentage of these birds contain microplastics in their gastrointestinal tracts, which may have implications for marine ecosystems and the bird's own health.

26-7-2024 DUNMORE EAST, IRELAND - NORTHERN FULMAR (Fulmarus glacialis)

The northern fulmar (Fulmarus glacialis), fulmar, or Arctic fulmar is a highly 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 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 family Procellariidae, which include petrels and shearwaters.

The northern fulmar and its sister species, the southern fulmar (Fulmarus glacialoides), 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 seven and nine 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 can be sprayed out of their mouths as a defense against predators from a very early age, and as an energy rich food source for chicks and for the adults during their long flights. It will mat the plumage of avian predators, and can lead to their death. Finally, they also have a salt gland that is situated above the nasal passage that helps desalinate their bodies, due to the high amount of ocean water that they imbibe. This gland excretes a high saline solution from their nose.
