The Eiao Marquesan warbler (Acrocephalus percernis aquilonis) is a subspecies of the northern Marquesan reed warbler found only in the dry upland forest on Eiao in the northern Marquesas Islands.
The species comprises several different races, each of which occupies a variety of forest or bushland habitats.
Because of extensive habitat destruction by feral goats, sheep and pigs, the subspecies is endangered, and may very well be extinct.
The total population was estimated at approximately 100-200 individuals in 1987.
The Marquesas Islands are a group of volcanic islands in French Polynesia, an overseas collectivity of France in the southern Pacific Ocean. Their highest point is the peak of Mount Oave on Ua Pou island, at 1,230 m (4,035 ft) above sea level.
Mohotani is an uninhabited island southeast of Hiva Oa and east of Tahuata in the southern Marquesas Islands. It has an area of 15 km2. Much of the island's sparse vegetation has been destroyed by feral goats and sheep, to the extent that following its rare rains, the sea around it is stained red from runoff. Early reports describes the island as fertile, with forest and fields. When Thor Heyerdahl visited the island in 1938, there were only a few goats and remains of deserted huts and villages.
Motu One is the name of a small sandbank with no vegetation, located on the western edge of a coral reef; the only atoll in the Marquesas Islands. The reef is approximately 5 kilometres (3.1 mi) in diameter, and the islet has a surface area of less than one hectare, rising only a few feet above sea level and changing shape regularly as the action of the currents deposits and removes sand.
Hatutu is a small island approximately 3 km (2 mi.) northeast of Eiao in the northern Marquesas Islands.
Eiao is the largest of the extreme northwestern Marquesas Islands. The island is uninhabited, but is administratively part of the commune (municipality) of Nuku-Hiva, itself in the administrative subdivision of the Marquesas Islands.
The Marquesan Nature Reserves are a network of small nature reserves in the Marquesas Islands. The reserves were declared by the government of French Polynesia in 1992, as a first step toward preserving the native flora and fauna of some of the smaller islands of the group.
The Hatutu Nature Reserve is a nature reserve encompassing the whole of the island of Hatutu in the northern Marquesas Islands. The reserve was declared in 1971, and is the primary nesting site of several endangered species, several of which are endemic, including the Hatutu Marquesan warbler and the Marquesas ground dove. The Hatutu Nature Reserve is home to one of the most important nesting grounds for the blue-footed booby.
The Hatutu Marquesan warbler, also called the Hatutu Polynesian warbler or the long-billed Polynesian warbler, is a subspecies of the northern Marquesan reed warbler. The subspecies is endemic to the island of Hatutu, and one of the primary breeding species in the Hatutu Nature Reserve.
The Eiao Nature Reserve is a nature reserve encompassing the whole of the island of Eiao in the northern Marquesas Islands, as well as several surrounding rocks. The reserve was declared in 1971, as a first step in preserving whatever remains of the devastated ecosystem, which has almost entirely been destroyed through over-grazing by feral goats, sheep and swine.
Ua Huka is one of the Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. It is situated in the northern group of the archipelago, approximately 25 mi (40 km) to the east of Nuku Hiva, at 8°54′S139°33′W.
The Marquesan kingfisher or Marquesas kingfisher is a species of bird in the family Alcedinidae. It is endemic to French Polynesia. It is threatened by habitat loss and predation by introduced species, and is currently classified as Critically endangered, with fewer than 500 individuals left in the wild.
Pomarea is a genus of birds in the monarch flycatcher family Monarchidae. The genus is restricted to the islands of Polynesia. The monarchs of this genus are around 15–19 cm long and most have sexually dimorphic plumage.
The Iphis monarch, or Ua Huka flycatcher, is a species of bird in the family Monarchidae. It is endemic to French Polynesia. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical moist shrubland, and plantations.
The Marquesan monarch is a species of bird in the family Monarchidae. It is endemic to French Polynesia. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest. It is threatened by habitat loss.
The southern Marquesan reed warbler is a species of Old World warbler in the family Acrocephalidae.
The northern Marquesan reed warbler is a species of Old World warbler in the family Acrocephalidae. It was formerly considered conspecific with the southern Marquesan reed warbler, and together known as the Marquesan reed warbler.
