Distribution

Region

Northwest Pacific and northwestern Indian Ocean

Typical Environment

Breeds on steep, remote volcanic islets where it nests in crevices and burrows. At sea it ranges over warm tropical waters far from land, often along convergence lines and areas of upwelling. It forages over the open ocean, typically close to the wave tops, and may gather where prey is concentrated by currents. Outside the breeding season it disperses widely to pelagic waters of the Arabian Sea and adjacent regions.

Useful to know

Matsudaira's storm petrel is a large, dark storm-petrel of the family Hydrobatidae, formerly placed in the genus Oceanodroma. It breeds on the remote Volcano Islands (Ogasawara), Japan, and disperses widely at sea after breeding. Outside the breeding season it is mostly found in the northwestern Indian Ocean. Its very restricted breeding range makes it vulnerable to disturbances and invasive predators.

Behaviour

Temperament

pelagic and wary

Flight Pattern

short rapid wingbeats with glides, often shearing low over waves

Social Behavior

Colonial nester on remote islands, using burrows or rock crevices. Adults visit colonies mainly at night to avoid predators and disturbance. Pairs are monogamous during the season and typically lay a single egg, with both parents sharing incubation and chick-rearing duties.

Migratory Pattern

Seasonal migrant

Song Description

Usually silent at sea, but at colonies gives soft, churring and rattling calls at night. Vocalizations are used for mate recognition and nest-site communication within dark nesting areas.

Maui ʻakepa

The Maui ʻākepa is an extinct species of ʻākepa that was endemic to Maui in the Hawaiian Islands. It was once common throughout the island, but introduced mosquitoes and other animals to Maui contributed to the declining population, and the bird has been listed as extinct by the IUCN Red List of Threatened Species since 2024. The latest confirmed sighting of this bird was in 1988, and in 2021 the United States Fish and Wildlife Service proposed declaring it extinct. The species was delisted from the Endangered Species Act on October 16, 2023 citing extinction.

Maui ʻalauahio

The Maui ʻalauahio, also known as the Maui Nui ʻalauahio or Maui creeper, is a species of Hawaiian honeycreeper. It is endemic to Maui Nui, Hawaii. The name Maui ʻalauahio is somewhat misleading because the species seems to have occurred on most, if not all, parts of the ancient Maui Nui, which includes the present day islands of Maui, Molokaʻi, Lānaʻi, and Kahoʻolawe. There are two subspecies: the Lānaʻi ʻalauahio, P. montana montana, which occurred on Lānaʻi (extinct); and P. montana newtoni which occurs on Maui. The common name refers to both groups.

Maui nukupuʻu

The Maui nukupuʻu is a species of nukupuʻu Hawaiian honeycreeper that was endemic to the island of Maui in the Hawaiian Islands. The small, five-inch-long bird lived only in eastern Maui, where it was dependent on high-elevation mesic and wet forests of ʻōhiʻa lehua and koa. These two species of trees attract insects, causing the Maui nukupuʻu to have a higher chance of finding a meal near these trees. It was last sighted in the late 1990's, and is most likely extinct.

Maui parrotbill

The kiwikiu or Maui parrotbill is a species of Hawaiian honeycreeper endemic to the island of Maui in Hawaii. It can only be found in 50 square kilometres (19 sq mi) of mesic and wet forests at 1,200–2,150 metres (3,940–7,050 ft) on the windward slopes of Haleakalā. This species is critically endangered, with an estimated population in 2016 of 250-540 individuals, but more recent estimates of less than 150 individuals. Fossil evidence indicates that the bird could at one time be seen in dry forests at elevations as low as 200–300 metres (660–980 ft), as well as on the island of Molokaʻi.

Mauritius blue pigeon

The Mauritius blue pigeon is an extinct species of blue pigeon formerly endemic to the Mascarene island of Mauritius in the Indian Ocean east of Madagascar. It has two extinct relatives from the Mascarenes and three extant ones from other islands. It is the type species of the genus of blue pigeons, Alectroenas. It had white hackles around the head, neck and breast and blue plumage on the body, and it was red on the tail and the bare parts of the head. These colours were thought similar to those of the Dutch flag, a resemblance reflected in its French common name, Pigeon Hollandais. The juveniles may have been partially green. It was 30 cm (12 in) long and larger and more robust than any other blue pigeon species. It fed on fruits, nuts, and molluscs, and was once widespread in the forests of Mauritius.
