[edit] Taxonomy

This is a monotypic species[1].

[edit] Diomedea vs. Phoebastria

Genera Phoebastria and Thalassarche formerly placed in the Diomedea, but now considered by virtually all authorities (Clements, Howard & Moore, AOU, BOU, SACC) to be separate genera in light of Nunn et al. (1996) and Penhallurick & Wink (2004).

[edit] Habitat

Breeds on islands, spends the rest of its life at sea.

[edit] Behaviour

Breeding does not start until about 7-8 years old, but the birds continue with annual breeding and are capable of living for at least 40 years. Goes on very long forays to get food for its young, up to 2.5 days between feeding.
