Procellaria

Procellaria is a genus of seabirds in the family Procellariidae, order Procellariiformes. Members of this genus are commonly called petrels and are large, dark-plumaged birds with the tubular nostrils characteristic of tubenoses. They are primarily pelagic, spending most of their lives far from land in the open oceans of the Southern Hemisphere.

Distribution and biology: Procellaria species breed on remote offshore islands and coastal cliffs, typically laying a single egg in a burrow or crevice. They are long-distance travelers, returning only to land for the breeding season. At sea, they feed mainly on fish, squid, and crustaceans, using surface-seizing and shallow pursuit methods to obtain food.

Taxonomy and species: The genus contains several species, including the white-chinned petrel (Procellaria aequinoctialis), the Westland petrel (Procellaria westlandica), and Parkinson's petrel (Procellaria parkinsoni). These birds are among the larger members of Procellariidae and occupy southern oceans, with distributions spanning areas around New Zealand, Australia, and various subantarctic islands.

Conservation: Many Procellaria species face threats from introduced predators on breeding islands and bycatch in longline fisheries. Conservation efforts, such as predator eradication programs on breeding sites and bycatch mitigation measures, are in place in various regions, and the conservation statuses of species within the genus vary accordingly.
