Genus

Storm-petrels are rather small and often dark colored tubenoses with a world wide distribution. All have fine black bills with very pronounced tubes. Storm Petrels are separated in two groups: the long legged, Southern Hemisphere birds subfamily Oceanitinae and the shorter legged species of more northern seas the subfamily Hydrobatinae. The first groups shows more morphological differences than the second. The genera are characterised on colour patterns, the condition of the nasal tubes, tail shape, structure of claws and proportions of the leg bones. The genus Oceanodroma consists of medium-sized petrels; plumage dark or greyish, often with pale rumps; tail more or less forked; tarsus short , middle toe with claw and scutellate; claws narrow.

Physical charateristics

Medium to large all dark storm-petrel reminiscent of Black Storm-petrel but with diagnostic white primary shafts. Head relatively large with steep forehead. Tail with a deep fork.

Range

Indian Ocean, Pacific Ocean : Central Indian Ocean, West Pacific Ocean. Oceanodroma matsudairae is only known to breed on the Iwo Islands, southern Japan. It may also breed on the Ogasawara Islands, but this requires confirmation.

Habitat

It is colonial, nesting in burrows on high ground on offshore islands. In the non-breeding season it is generally pelagic, occurring far from the coast.

Reproduction

It is colonial, nesting in burrows on high ground on offshore islands. Breeding is thought to begin in January with most fledging taking place in June

Feeding habits

Little data on diet, feeds by dipping and snatching from surface. Sometimes follows ship

Migration

After the breeding season, it is thought to move south across the equator, perhaps to the Timor Sea off north-west Australia, and then west into the Indian Ocean, where it winters mostly in the equatorial belt around the Seychelles and west to Somalia and Kenya. Some birds may winter off north-east New Guinea.
