Shy albatross

This mollymawk was once considered to be the same species as the Salvin's albatross, Thalassarche salvini, and the Chatham albatross, Thalassarche eremita, but they were split around 2004. In 1998, Robertson and Nunn suggested a four-way split including the white-capped albatross, Thalassarche steadi. The three-way split was accepted by Brooke in 2004, the ACAP in 2006, SACC in 2008, and BirdLife International by 2000. James Clements was the last major holdout on the three-way split but later accepted it. The fourth split, steadi, was only accepted by the ACAP in 2006, Mollymawks belong to the albatross family, Diomedeidae, which shares the order Procellariiformes with shearwaters, fulmars, storm petrels, and diving petrels. Procellariiformes have certain identifying features. They have nasal passages that attach to the upper bill, called naricorns (although the nostrils on the albatross are on the sides of the bill). The bills are also unique in that they are split into between seven and nine horny plates. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy-rich food source for chicks and for the adults during their long flights. They also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, required due to the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose. Within Australia, the bird is still shown as Diomedea cauta, Diomedea cauta cauta, or Thalassarche cauta cauta in some legislation and databases. ==Description==

The shy albatross averages in length, wingspan, and in weight. Alongside its similarly sized sister species, the Salvin's albatross, this species is considered the largest of the mollymawks or the small albatrosses. It is a black, white and slate-grey bird with the characteristic black thumb mark at the base of the leading edge of the underwing. Adults have a white forehead and a crown, which is bordered on the bottom with a dark eyebrow and pale grey face. Its mantle, tail and upperwing are grey-black, and the rest is white. Its bill is grey-yellow with a prominent yellow culmen and yellow tip. It has a lifespan of about 60 years. ==Behaviour==

Feeding The shy albatross feeds by a combination surface-seizing and some pursuit diving – it has been recorded diving as deep as . Fish, cephalopods, crustacea, and tunicates are the sustenance for this species. Reproduction The shy albatross breeds on rocky islands and builds mounded nests of soil, grass, and roots. They lay one egg in the second half of September. Flight endurance Some shy albatross are able to fly in 24 hours. ==Range and habitat==

The shy albatross is endemic breeder to Australia and it breeds on three island colonies off Tasmania, in the southern Indian Ocean: Albatross Island, Pedra Branca, and the Mewstone. It is the only albatross endemic to Australia. It is sometimes found off the Pacific coast of the United States. ==Conservation==

The IUCN classifies this species as near threatened, Today, longline fishing still impacts this species but their numbers have been maintained despite this threat. Finally, the Australasian gannet, Morus serrator is the primary threat to their survival. Listings under state and territory legislation were mostly still "vulnerable" at this time. The bird can only be monitored on Albatross Island, as the other two islands are inaccessible, but there are thought to be 15,000 pairs of shy albatross left. ==Footnotes==
