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.
The marsh warbler is an Old World warbler currently classified in the family Acrocephalidae. It breeds in temperate Europe and the western Palearctic and winters mainly in southeast Africa. It is notable for incorporating striking imitations of a wide variety of other birds into its song.
The Cape Verde warbler is an Old World warbler in the genus Acrocephalus. It is also known as the Cape Verde cane warbler or Cape Verde swamp warbler, and in Creole as tchota-de-cana or chincherote. It breeds on Santiago, Fogo, and São Nicolau in the Cape Verde Islands. It previously bred on Brava. This species is found in well-vegetated valleys, avoiding drier areas. It nests in reedbeds, two to three eggs being laid in a suspended nest.
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 millerbird is a species of Old World warbler in the family Acrocephalidae. It has two subspecies, A. f. kingi and A f. familiaris. The latter, the Laysan millerbird, became extinct sometime between 1916 and 1923. The former, the critically endangered Nihoa millerbird, remains the only race left, inhabiting the small island Nihoa in Hawaiʻi, though it has since been reintroduced to Laysan. It is the only Old World warbler to have colonised Hawaiʻi, although there is no fossil evidence that the species ever had a distribution beyond these two islands.
Schizostachyum glaucifolium, common name Polynesian ʻohe, is a species of bamboo.
The nightingale reed warbler, or Guam reed-warbler, was a songbird endemic to Guam. It has not been seen since 1969.
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 Acrocephalidae are a family of oscine passerine birds, in the superfamily Sylvioidea.
The Rimatara reed warbler is a species of Old World warbler in the family Acrocephalidae. It is found only in Rimatara in French Polynesia. Its natural habitats are subtropical or tropical dry forests and swamps. Due to its limited geographic distribution, this bird is classified as critically endangered on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.
The speckled reed warbler or streaked reed warbler is an Old World warbler in the family Acrocephalidae. The species was first described by Robert Swinhoe in 1863.
The Saipan reed warbler is a critically endangered songbird of the Northern Mariana Islands. It is considered a subspecies of the nightingale reed warbler by some taxonomists. It occurs on two islands: Saipan and Alamagan. An estimated population of 2700 birds was reported in 2009 on Saipan, and on Alamagan 950 birds were reported in 2010.
The Pagan reed warbler was sometimes considered a subspecies of the nightingale reed warbler. It originally occurred on Pagan Island and "was extinct by the late 1970s". More precisely, in the 1970s, the 1980s, in 2000 and in 2010, the bird could not be found and is therefore presumed to be extinct.
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.
Garrett's reed warbler, sometimes called Society Islands reed warbler or Forster's reed-warbler was 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. It was endemic to Raiatea and Huahine in the Society 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.
The Aguiguan reed warbler or Aguijan reed warbler was a bird that originally occurred on the Northern Mariana Island Aguigan. It is considered a subspecies of the nightingale reed warbler by some taxonomists. Of this subspecies there never have been reports of a substantial population. In 1982 only four up to possibly 15 birds of the subspecies have been counted, and since 1995 none has been sighted, despite extended efforts to find specimens.
