Buller's albatross or Buller's mollymawk (Thalassarche bulleri), is a small mollymawk in the albatross family.
It breeds on islands around New Zealand, and feeds in the seas off Australia and the South Pacific.
Mollymawks are a type of albatross that belong to the 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 called naricorns that attach to the upper bill, 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 seven to 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 large amount of ocean water that they imbibe. It excretes a highly saline solution from their nose.
In 1998, C.J.R. Robertson and G. B. Nunn split this species into two, Thalassarche (bulleri) bulleri, and Thalassarche (bulleri) platei, although the majority of authorities including ITIS,James Clements,BirdLife International, and Michael Brooke have not yet accepted this split
