Diomedea cauta eremita is a medium sized black and white albatross which breeds only on The Pyramid, a large rock stack in the Chatham Islands, New Zealand (Aotearoa). It is sometimes treated as a subspecies of the shy albatross Thalassarche cauta. It is the smallest of the shy albatross group.

Mollymawks are a type of albatross that belong to family Diomedeidae of the order Procellariiformes, 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 seven and nine 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 that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose. The Chatham albatross, with the white capped, shy and Salvin's albatrosses, were all considered the same species until a 1998 book by Robertson and Nunn. Other experts followed suit, with BirdLife International in 2000, Brooke in 2004, ACAP in 2006, and SACC in 2008. Though some, such as James Clements, did not agree. The Chatham albatross was first described as Diomedea cauta eremita by Robert Cushman Murphy, in 1930, based on a specimen from Pyramid Rock. krill, and barnacles.

The IUCN has classified this species as Vulnerable, The conditions have been improving since 1998. As with other albatrosses, commercial fishing impacts their survival, with longline and the occasional trawl line. Illegal harvesting of chicks occurs occasionally. In 2014, the Chatham Islands Taiko Trust translocated 50 juvenile albatrosses to a protected breeding site on Main Chatham Island, some 50 km north of the Pyramid. It was hoped that a new colony could be established within five years which would give the species a chance to thrive in less extreme conditions. In total 300 chicks were trans located over the period 2014 to 2018. Each day during the period of the project, 60KG of a squid and fish mixture was prepared, warmed and fed, to the chicks by volunteers of the Chatham Island Taiko Trust. The success or the translocation project is not yet confirmed. The birds, once they depart the colony, spend five to seven years at sea. If the birds return to nest on the new location this will provide an indication of the projects' success.
