The Acrocephalus warblers are small, insectivorous passerine birds belonging to the genus Acrocephalus. Formerly in the paraphyletic Old World warbler assemblage, they are now separated as the namesake of the marsh and tree warbler family Acrocephalidae. They are sometimes called marsh warblers or reed warblers, but this invites confusion with marsh warbler and reed warbler proper, especially in North America, where it is common to use lower case for bird species.
The common reed warbler is an Old World warbler in the genus Acrocephalus. It breeds across Europe into the temperate western Palaearctic where it is migratory, wintering in sub-Saharan Africa. It is also a resident species over large parts of Africa.
Blyth's reed warbler is an Old World warbler in the genus Acrocephalus. It breeds in the Palearctic and easternmost Europe. It is migratory, wintering in Bangladesh, India and Sri Lanka. It is one of the most common winter warblers in those countries. It is a rare vagrant to western Europe.
The paddyfield warbler is a species of marsh warbler. It was formerly included in the "Old World warbler" assemblage. The Manchurian reed warbler was included in A. agricola as a subspecies.
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.
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.
The Tahiti reed warbler is a songbird in the genus Acrocephalus. It used to be placed in the "Old World warbler" assemblage (Sylviidae), but is now in the newly recognized marsh warbler family Acrocephalidae. It is endemic to the island of Tahiti.
The Pitcairn reed warbler is a songbird in the genus Acrocephalus. Formerly placed in the "Old World warbler" assemblage (Sylviidae), it is now in the newly recognized marsh-warbler family Acrocephalidae.
The Basra reed warbler is a "warbler" of the genus Acrocephalus. It is an endemic breeder in Southwestern Iran, East and southern Iraq, Kuwait, and Israel in extensive beds of papyrus and reeds. It is easily mistaken for the great reed warbler but is a bit smaller, has whiter underparts and has a narrower, longer and more pointed bill. It winters in East Africa. It is a very rare vagrant in Europe. The call is a gruff chaar, deeper than a reed warbler's.
The lesser swamp warbler or Cape reed warbler is an Old World warbler in the genus Acrocephalus. It is a resident breeder in Africa from the Democratic Republic of the Congo, the Chad and Ethiopia south to South Africa. This is a common species of reedbeds in standing water.
The Acrocephalidae are a family of oscine passerine birds, in the superfamily Sylvioidea.
The black-browed reed warbler is a marsh-warbler in the family Acrocephalidae. It was formerly included in the "Old World warbler" assemblage. The species was first described by Robert Swinhoe in 1860.
Marquesan reed warbler has been split into the following two species:
The Manchurian reed warbler, also known as the Manchurian reed-warbler, is a species of marsh-warbler. It was formerly included in the "Old World warbler" assemblage, and was usually treated as a subspecies of the paddyfield warbler. It is found in Cambodia, China, Hong Kong, South Korea, Laos, Russia, Thailand, Vietnam, Malaysia and possibly Myanmar. Its natural habitat is swamps. It is threatened by habitat loss.
The Oriental reed warbler is a passerine bird of eastern Asia belonging to the reed warbler genus Acrocephalus. It was formerly classified as a subspecies of the great reed warbler of the western Palearctic.
The Mangareva reed warbler or Astrolabe reed warbler is a presumed extinct songbird that existed on Mangareva in the Gambier Islands. It is known from only two specimens, and is believed to have gone extinct in the mid-19th century, likely due to deforestation and the introduction of exotic predators.
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. It is found on the northern Marquesas Islands.
The Nauru reed warbler is a passerine bird endemic to the island of Nauru in the Pacific Ocean. It is one of only two native breeding land-birds on Nauru and it is the only passerine found on the island. It is related to other Micronesian reed warblers, all of which evolved from one of several radiations of the genus across the Pacific. Related warblers on nearby islands include the Caroline reed warbler, with which the Nauru species was initially confused, and the nightingale reed warbler, which was formerly sometimes considered the same species.
