Short tailed albatross also named the Steller's albatross with its scientific name Phoebastria albatrus is a rare marine bird in the North Pacific.

Although the North Pacific is related to other albatrosses, the Short tailed albatross also exhibits behavioral and morphological links with albatrosses in the southern oceans.

Short tailed albatross was described by the German naturalist Peter Simon Palace from the skins collected by Georgie Wilhelm Stellar (after which its other common name came up).

Once common, Short tailed albatross was brought to extinction by trade-feathers, but with protection has recently been restored.

Description

The short-tailed albatross is a medium-sized albatross, with a wingspan of 215 to 230 cm (85-91 in), a length of 84 to 94 cm (33-37 in) and a body weight that can be 4.3 to 8.5 kg (9.5-18.7 lb).

Among standard measurements, the bill is 12.7-15.2 cm (5.0-6.0 in) long, the tail is 14-15.2 cm (5.5-6.0 in) long, the tarsus around 10 cm (3.9 in) and the wing chord 51 cm (20 in).

As an adult, feathers of the Short tailed albatross white with black flying feathers, some covering, as well as a black terminal bar on its tail. It has yellow-stained naps and crowns.

Its bill is large and pink; However, the older bird will gain a blue tip. Adolescents are brown in color and will turn white in about 10 to 20 years as they turn.

It can be distinguished from the description of the other two species in its range, albatross, Lassan albatross, and the large size of albatross on black legs and its pink bill (with a blue tip) as well as its division.

Contrary to its name, tail of the Short tailed albatross is no less than a Lassan or a black pail and is actually longer than the Wave Albertos, another member of the Foebestria tribe.

Scope and habitat

Short-tailed albatrosses now nest on four islands, most of the birds' nest in Torishima, and almost all of the rest of the nest in Minami-Kojima on Senkaku Island.

In the late 2000s, a female-to-female pair began to nest on the Curie, but to date, they have not been able to produce any viable eggs.

A raid struck mid-January 14 at Midway. Midway and Kure are both in the northwestern Hawaii Islands. In 2002, a pair of eggs began to hatch in Muko-Jima in the Bonin Islands, Japan.

During the breeding season, males and juveniles of the Short tailed albatross gather in the Bering Sea across the North Pacific, and females feed on the coast of Japan and eastern Russia.

They can also be found east of California. In fact, short-tailed albatrosses have been listed on many endangered species in the United States, including Washington.

The Short tailed albatross species has been dedicated as a breeder of Kita-no-Shima, Anayetak atoll, Kobishi and the Bonin Islands (Nishino Shima, Yomazima, and (until recently Mukojima), which was formerly born in Bermuda during the Pleistocene.

Upbringing

Short-talied albatross feeds on squid basically, but ships will follow for their canceled offer.

Reproduction

This albatross historically preferred nesting in the large open space near the grass stand, Miskanthaus sinensis.

Short-tailed albatross usually breeds first within the age of 10 years.

Short-tailed albatross gives an egg that is dirty white, mainly reddish-brown on the edges of the egg.

It usually measures 116 by 74 millimeters (4.6 inред 2.9 in). The egg is incubated for about 65 days. Both sexes hatch.

IUCN classifies this species as vulnerable, with a breeding range of 34,800,000 km2 (13,400,000 sq mi) and 9 km2 (3.5 sq mi).

Short-tailed albatross came dangerously close to extinction. In the second half of the nineteenth century, they were hunted on an industrial scale for their feathers, with some estimates claiming that upwards of 3 million birds were hunted.

By the 9th, only the population was in Toryshima, between 1233 and 9, the Japanese government announced a ban on hunting for species, then the albatrosses stopped breeding on the island.

At this time, the species has become extinct and with the onset of World War II, research was thought to be impossible.

An American researcher on the island declared the species to be extinct in the year 5, but there were an estimated 5 individuals, probably juveniles, living in the sea (not all albatross species took long to reach sexual maturity and would not return to their native colony for many years).

After the birds returned, they were protected more carefully, and the birds returned in the first 3, laid the first eggs.

Like other albatross species, the Short tailed albatross species were also discovered on a variety of albatross decoys on the island. Keeping in a group is tempting to breed.

Today, prolonged fisheries and volcanic eruptions are the biggest threat to Tory-Shima; However, induced predators, environmental pollutants, soil instability, and extreme weather are also threatened for Short tailed albatross.
