Distribution and habitat

Breeds on islands off New Zealand, rapidly migrating in the non-breeding season across the South Pacific Ocean to the west coast of South America. It is a rare vagrant to southern Africa, with two records between 1995 and 2003 off the coast of the Cape Peninsula, Western Cape.

Food 

Eats squid, fish, crustaceans, tunicates and carrion, often foraging behind shipping vessels and cetaceans. The New Zealand study by James and Stahl (2000) showed that Buller's albatross in that region eats the following food (percentage occurrence followed by percentage weight are given in brackets):

  • Fish discards from boats (70%, 60%)
  • Fish (naturally caught) (?, 5%)
  • Pelagic tunicates (Thaliacea)
  • Cephalopods (53%, 7%) mainly:
    • Histioteuthis atlantica (20%, < 0.5%)
    • Nototodarus spp. (arrow squid) (34%, 1%)
    • Pinnoctopus cordiformis (20%, 4%)
  • Crustacea (37%, 2%)
  • Other (?, 2%)

Threats

Vulnerable, largely due to longline mortalities and storm damage at its Chatham Island breeding colony (linked to global warming).
