Northern Fulmar, scientific name Fulmarus glacialis, or only Fulmar or sometimes call Arctic fulmar is a large number of sea birds originally found in the Subarctic regions of the North Atlantic and North Pacific. In the southern hemisphere, a definite view has been made, a single bird has been seen in the south of New Zealand.

Northern Fulmar comes in one of two color shapes: a light, white head and body, and gray wings and tail and a dark one that looks similar to the same gray anus, but the fulmar is actually a family member Procellariidae, which includes petrel and shearwater.

The Northern Fulmar and its sister species, the southern Fulmar or Fulmarus glacialis, are an existing member of the Fulmarus genus.

Northern Fulmar shares specific characteristics. First, they have nasal passages attached to the upper bark called naricorns.

However, the nose flowers on the albatrosses are on the side of the bill, unlike the whole order with the full order, which has the nostrils on the upper bill. The bills of the Proceduraliforms are also distinct in that they are divided into seven to nine horny plates.

One of these plates forms the hooded portion of the upper bill, called the maxillary vagus. They produce a stomach oil made of wax esters and triglyceride that is stored in the proventriculus.

It can be sprayed from the mouth at a very young age as a defense against predators and as a powerful food source for rats and adults during their long flights.

It will cure avian predators' plumage and can lead to their death. Finally, they have a salt gland that is located above the nasal passages that help to distinguish their bodies, due to the high amount of seawater that they suffer from. This gland releases a high saline solution from its nose.

Description

The northern fulmar has wings of 102 to 112 cm (40-44 inches) and lengths of 46 cm (18 inches). Body mass can range from 450 to 1,000 grams (16 to 35 oz).

This species is pale yellow, dense, gray and white with bill and blue legs; However, it is both light and dark, or 'blue'.

There is also an intermediate form in the Pacific Ocean. There are certain matches of all shapes, such as the darker shapes just above the dark edge, and the top of all these wings have a pale inner primary. The Pacific Atlantic has a thicker tail than size.

Like other patrols, their ability of Northern Fulmar to move is also limited, but they are stronger flyers, with a more rigid wing than the cheekbones, with the cheekbones showing on the bull's neck and having a short stubby bill. These are long-lasting, 31-year life expectancies are not uncommon.

Behavior

These fullers will be fed with shrimp, fish, squid, plankton, jellyfish, and carrion as well. While eating fish, they dive a few feet deep to retrieve their prey.

Breeding

The Northern Fulmar begins breeding between six and twelve years. It forms monopoly and long-term pair bonds. It returns to the same nest site year after year.

The breeding season begins in May; however, women have glands that store sperm and allow weeks to pass between eggs. Their nest is lined with scrap, soft material on the shore of a plant on the grass or on the ground.

Birds build nests in large colonies, recently they have begun nesting on roofs and buildings. Both sexes are involved in the nesting process.

A single white egg, mm৪ mm × 9 mm (2.5 in. 2.5 in) of both sexes, is transmitted by both sexes for 50 to 54 days. Ultrasound chickens are brooded for 2 weeks and completely destroyed after 70 to 75 days.

Again both sexes are involved. During this time, the parents are nocturnal, and will not be active even on a well-lit night.

Save

The Northern Fulmar is estimated to have 15,000,000 to 30,000,000 mature individuals, which occupy 28,400,000 km 2 (11,000,000 square miles) and their North American population is growing, so it is listed with the IUCN at least as a concert.

The range of this species has increased greatly in the last century due to the availability of fishing from the commercial fleet, but less food and climate change from these sources may result in an agreement. Population growth has been particularly significant in the British Isles.
