Tree warblers are medium-sized warblers in the marsh- and tree-warbler family Acrocephalidae. They are found in Europe, Africa and western Asia. Until recently, they were all classified in the single genus Hippolais.
The western subalpine warbler is a small typical warbler which breeds in the southernmost areas of Europe and north-western Africa.
The common grasshopper warbler is a species of Old World warbler in the grass warbler genus Locustella. It breeds across much of temperate Europe and the western Palearctic. It is migratory, wintering in north and west Africa.
Savi's warbler is a species of Old World warbler in the grass warbler genus Locustella. It breeds in Europe and the western Palearctic. It is migratory, wintering in northern and sub-Saharan Africa.
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 sedge warbler is an Old World warbler in the genus Acrocephalus. It is a medium-sized warbler with a brown, streaked back and wings and a distinct pale supercilium. Sedge warblers are migratory, crossing the Sahara to get from their European and Asian breeding grounds to spend winter in Africa. The male's song is composed of random chattering phrases and can include mimicry of other species. The sedge warbler is mostly insectivorous.
The aquatic warbler is an Old World warbler in the genus Acrocephalus. It breeds in temperate eastern Europe and western Asia, with an estimated population of 11,000-15,000 pairs. It is migratory, wintering in west Africa. After many years of uncertainty, the wintering grounds of much of the European population were finally discovered in Djoudj National Bird Sanctuary, Senegal, with between 5,000 and 10,000 birds present at this single site. Its south-westerly migration route means that it is regular on passage as far west as Great Britain and Ireland.
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.
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 great reed warbler is a Eurasian passerine in the genus Acrocephalus.
The thick-billed warbler breeds in the temperate east Palearctic, from south Siberia to west Mongolia. It is migratory, wintering in tropical South Asia and South-east Asia. It is a very 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.
The eastern olivaceous warbler is a small passerine bird with drab plumage tones, that is native to the Old World. For the most part it breeds in southeastern Europe, the Middle East and adjacent western Asia, and winters in the northern Afrotropics.
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 clamorous reed warbler is an Old World warbler in the genus Acrocephalus. It breeds from Egypt eastwards through Pakistan, Afghanistan and northernmost India to south China and southeast Asia. A. s. meridionalis is an endemic race in Sri Lanka.
The Australian reed warbler is an Old World warbler in the genus Acrocephalus and is the only Acrocephalus species native to Australia. It has also been observed in Papua New Guinea and nearby islands. The name Acrocephalus refers to the peaked crown found on reed warblers in this genus and can be translated to mean "topmost head" in Greek. The species name australis is translated to mean "southern" in Latin, and refers to the species range, Australia. In its western range the Australian reed warbler is also known as "Koordjikotji" in the local Aboriginal language of Perth and its surrounds.
The Seychelles warbler, also known as Seychelles brush warbler, is a small songbird found on five granitic and corraline islands in the Seychelles. It is a greenish-brown bird with long legs and a long slender bill. It is primarily found in forested areas on the islands. The Seychelles warbler is a rarity in that it exhibits cooperative breeding, or alloparenting, which means that the monogamous pair is assisted by nonbreeding female helpers.
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.
