Buller's albatross (Thalassarche bulleri) or Buller's mollymawk, is a small mollymawk in the albatross family.
It breeds on islands around
Pacific
.
Taxonomy
Mollymawks are a type of albatross that belong to the family
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.[3] 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.[4]
In 1998, C.J.R. Robertson and G. B. Nunn split this species into two, Thalassarche (bulleri) bulleri, and Thalassarche (bulleri) platei, have not yet accepted this split
Etymology
It was named for the New Zealand
ornithologist Walter Buller
.
Description
Buller's albatross averages 79 cm (31 in). It has a silver-grey forehead, a grey head and throat. It has a black patch around the eyes with a white crescent behind and below the eye. Its back, upperwing, and tail are dark grey, and its rump and underparts are white. Its underwing is white with a black tip, with a broad sharply demarcated dark band at the leading edge. Its bill is large and black with yellow on the upper mandible, and the tip. The juvenile has a darker head and a brown bill.[8]
Behaviour
Reproduction
The Buller's albatross is
incubation lasts around 60 days, with both parents sharing the responsibility. The average incubation shift is around 10 days. After hatching it takes 170 days to fledge the chick. They breed annually.[8]

Buller's albatross is
Three Kings Islands (Rosemary Rock). Adults forage between 40°S and 50°S from Tasmania to the Chatham Rise.[13][14][15][16][17] Juveniles and adults that aren't breeding disperse across the South Pacific with a number feeding every year in the Humboldt Current off Chile and Peru.[8][14][18][19]
Conservation
It was formerly classified as a
Big and Little Sister, 20 pairs on Rosemary Rock in the Three Kings group.[22]
The Snares Islands population has been increasing, but lately not as much as in the 1970s,Big and Little Sister, adult survival rate is 93.5% and the brooding success rate is between 57-60%.[22]
Buller's albatross is the most common
Big Sister and may take eggs and chicks.[19] Most islands are legally protected, except for the Chatham Islands
colonies which are on private land.
