Taxonomy
This is a monotypic species.
Habitat
Pelagic species; at sea, and commonly along coastlines. Is not bothered by human settlement, and may benefit from human activities such as fishing.
Behaviour
Diet includes fish, especially flyingfish, which are taken in flight. Will attack other seabirds to steal their catches or try to force them to disgorge their meals. Will also snatch offal, such as fish entrails discarded by fishermen, from the surface of the sea.
The male attend the nest for about 100 days, while the female stays with the single offspring for approximately another year; most of that time, the young stay in the nest. The female is therefore only able to breed every other year, while males may breed every year or maybe even more often in different colonies.
