ACAP Annex 1. The species was first studied in the 1940s. Feral sheep were eradicated from the north of Campbell Island, where the nesting colonies are, in 1971, and then from the island itself in 1991. Research includes studies on population dynamics, colony distribution, biology, diet and foraging7. The islands are a national nature reserve, and part of a World Heritage Site, declared in 1998. Rats and cats were eradicated from Campbell in 2001, and an expedition in 2003 found no evidence of them persisting15. Conservation Actions Proposed
Complete ground census of colonies for three consecutive years every 10 years, and repeat photopoints at least every five years. Search intensively for banded birds in two consecutive years at five- year intervals. Complete research to clarify fisheries interactions. Further develop mitigation devices/techniques to minimise fisheries bycatch in trawl and pelagic longline fisheries.
The Campbell Albatross or Campbell Mollymawk (Thalassarche impavida) is a medium-sized mollymawk in the albatross family. It breeds only on Campbell Island and the associated islet of Jeanette Marie, a small New Zealand island group in the South Pacific. It is sometimes considered a subspecies of the Black-browed Albatross. It is a medium-sized black and white albatross with a pale yellow iris.
Mollymawks are a type of albatross that belong to Diomedeidae family and come from the Procellariiformes order, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, 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 of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates. Finally, 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 situated above the nasal passage which helps desalinate their bodies, necessary due to the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose.
In 1998, Robertson & Nunn suggested the species be split off of the Black-browed Albatross, Thalassarche melanophrys. Over the course of the next few years more experts agreed, starting with BirdLife International in 2000, followed by Brooke in 2004. James Clements has not agreed yet, neither has ACAP, and SACC recognizes the need for a proposal.
It weighs 3.21 kg (7.1 lb) and is 88 cm (35 in) long. The adult is very similar to the Black-browed Albatross, differing in eye colour. It has a white head, neck, rump, and underparts, with a black upperwing, back, and tail. The underwing is white with broad black edging. It has a black triangle around the eye that reaches the bill, which is yellow with an orange tip. They also have a pale yellow iris. The juveniles have a brown-grey bill with a black tip, dark eyes and less black on the underwing. The average life expectancy is given as 28 years, though this is likely due to lack of study as most Albatross can live to well beyond 50 years.
Range and habitat

The Campbell Albatross breeds on the northern and western coastline of Campbell Island and the islet Jeanette Marie. When breeding they forage from South Island and the Chatham Rise to the Ross Sea. Juveniles and non-breeders will go only through south Australian water, the Tasman Sea, and southwestern Pacific Ocean.
Breeding birds like to nest on ledges and steep slopes covered with low grass, tussock, or mud. They start breeding at 10 years and they have a breeding success rate of 66%. Adults return to the breeding colony in early August and begin laying in late September. The single egg is incubated for around 70 days. The chicks fledge after about 130 days after hatching.
The IUCN classifies this species as Vulnerable due to the limited number of breeding locations. The most recent estimate was in 1997 and counted 24,600 pairs. Between 1992 and 1997 sampled colonies have been increasing at the rate of 1.8%. Adult survival rate is at 94.5%. It has an occurrence range of 31,700,000 km2 (12,200,000 sq mi) and a breeding range of 13 km2 (5.0 sq mi).
