The two to five species of Polynesian sandpipers, the only members of the genus Prosobonia, are small wading birds confined to remote Pacific islands of French Polynesia. Only one species now exists, and it is rare and little known. This bird is sometimes separated in the genus Aechmorhynchus, restricting the genus to the extinct southern forms.
Swiftlets are birds contained within the four genera Aerodramus, Hydrochous, Schoutedenapus and Collocalia. They form the Collocaliini tribe within the swift family Apodidae. The group contains around thirty species mostly confined to southern Asia, south Pacific islands, and northeastern Australia, all within the tropical and subtropical regions. They are in many respects typical members of the Apodidae, having narrow wings for fast flight, with a wide gape and small reduced beak surrounded by bristles for catching insects in flight. What distinguishes many but not all species from other swifts and indeed almost all other birds is their ability to use a simple but effective form of echolocation to navigate in total darkness through the chasms and shafts of the caves where they roost at night and breed. The nests of some species are built entirely from threads of their saliva, and are collected for the famous Chinese delicacy bird's nest soup.
Aerodramus is a genus of small, dark, cave-nesting birds in the Collocaliini tribe of the swift family. Its members are confined to tropical and subtropical regions in southern Asia, Oceania and northeastern Australia. Many of its members were formerly classified in Collocalia, but were first placed in a separate genus by American ornithologist Harry Church Oberholser in 1906.
Mangaia is the most southerly of the Cook Islands and the second largest, after Rarotonga. It is a roughly circular island, with an area of 51.8 square kilometres (20.0 sq mi), 203 kilometres (126 mi) from Rarotonga. Originally heavily populated, Mangaia's population has dropped by 75% in the last 50 years.
Atiu, also known as Enuamanu, is an island of the Cook Islands archipelago, lying in the central-southern Pacific Ocean. Part of the Nga-pu-Toru, it is 214 km (133 mi) northeast of Rarotonga. The island's population has dropped by two-thirds in the last 50 years.
Gallirallus is a genus of rails that live in the Australasian-Pacific region. The genus is characterised by an ability to colonise relatively small and isolated islands and thereafter to evolve flightless forms, many of which became extinct following Polynesian settlement.
The uniform swiftlet,, also known as the Vanikoro or lowland swiftlet, is a gregarious, medium-sized swiftlet with a shallowly forked tail. The colouring is dark grey-brown, darker on the upperparts with somewhat paler underparts, especially on chin and throat. This species is widespread from the Philippines through Wallacea, New Guinea and Melanesia. It forages for flying insects primarily in lowland forests and open areas. It nests in caves where it uses its sense of echolocation, rare in birds, to navigate.
The blue lorikeet is a small lorikeet from French Polynesia and the Cook Islands. It is also known as the Tahiti lorikeet, violet lorikeet, Tahitian lory, blue lory, nunbird, and the indigo lory. It was formerly found on 23 islands around Tahiti, but now restricted to perhaps eight islands: Motu, Manuae, Tikehau, Rangiroa, Aratua, Kaukura, Apataki, Aitutaki, and possibly Harvey Island and Manihi. Its plumage is mainly dark blue and it has a white area over its upper chest, throat and face. The first captive breeding in the UK was by the Marquess of Tavistock in the 1930s. He was awarded a silver medal by the Foreign Bird League for this achievement.
The conquered lorikeet is a species of parrot that became extinct 700–1300 years ago. It lived in islands of Polynesia. David Steadman and Marie Zarriello wrote its species description in 1987.
The edible-nest swiftlet, also known as the white-nest swiftlet, is a small bird of the swift family which is found in South-East Asia. Its opaque and whitish nest is made exclusively of solidified saliva and is the main ingredient of bird's nest soup, a delicacy of Chinese cuisine.
Collocalia is a genus of swifts, containing some of the smaller species termed "swiftlets". Formerly a catch-all genus for these, a number of its former members are now normally placed in Aerodramus.
The Mariana swiftlet or Guam swiftlet is a species of swiftlet in the family Apodidae.
The Atiu swiftlet is a species of bird in the swift family, endemic to Atiu in the Cook Islands.
The great ground dove is an extinct species of bird in the family Columbidae. It was found in Mangaia in the southern Cook Islands, and in French Polynesia where subfossil bones between 1000 and 2000 years old have been found in the Marquesas, as well as between 750 and 1250 years old at the Fa'ahia early occupation site on Huahine in the Society Islands.
The Mangaia rail is an extinct species of flightless bird in the rail family, Rallidae.
The Mangaia crake is an extinct species of flightless bird in the rail family, Rallidae.
The Apodinae are a subfamily of swifts and contain the following species:
The Cook Islands tropical moist forests is a tropical and subtropical moist broadleaf forests ecoregion that covers the Southern Cook Islands in the Cook Islands.
