These birds are often found in the neritic zone, the region of the ocean that extends from the coastline to the edge of the continental shelf, where they actively forage for food. They also frequently venture into the oceanic zone, a vast expanse of open ocean beyond the continental shelf.

Thalassarche bulleri belongs to the Class: Aves, Order: Procellariiformes, and Family: Diomedeidae. The family Diomedeidae comprises all albatross species, which are characterized by their large size, long wingspans, and distinctive hooked beaks. The Procellariiformes order encompasses a wide variety of seabirds, including petrels, shearwaters, and fulmars, all sharing adaptations for a pelagic lifestyle.
Feeding
Thalassarche bulleri is a highly skilled predator, primarily feeding on squid, fish, and crustaceans. They typically forage by skimming the surface of the ocean, using their keen eyesight to spot prey. They also dive to capture prey underwater, utilizing their powerful wings and webbed feet for maneuverability.
