Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. A smaller family of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.
The Old World flycatchers are a large family, the Muscicapidae, of small passerine birds mostly restricted to the Old World. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing. The family includes 324 species and is divided into 51 genera.
The grass warblers are small passerine birds belonging to the genus Locustella. Formerly placed in the paraphyletic "Old World warbler" assemblage, they are now considered the northernmost representatives of a largely Gondwanan family, the Locustellidae.
The cuckooshrikes and allies in the family Campephagidae are small to medium-sized passerine bird species found in the subtropical and tropical Africa, Asia and Australasia. The 93 species are divided into 11 genera. The woodshrikes (Tephrodornis) were often considered to be in this family but are now placed in their own family, Vangidae, along with the philentomas and the flycatcher-shrikes. Another genus, Chlamydochaera, which has one species, the black-breasted fruithunter, was often placed in this family but has now been shown to be a thrush (Turdidae).
The family Cisticolidae is a group of about 160 warblers, small passerine birds found mainly in warmer southern regions of the Old World. They were formerly included within the Old World warbler family Sylviidae.
The Sri Lanka bush warbler, also known as Ceylon bush warbler or Palliser's warbler, is an Old World warbler which is an endemic resident breeder in Sri Lanka, where it is the only bush warbler.
The neotropical parrots or New World parrots comprise about 150 species in 32 genera found throughout South and Central America, Mexico, and the Caribbean islands. They are also present on a few Pacific islands such as the Galápagos. Among them are some of the most familiar and iconic parrots, including the blue and gold macaw, sun conure, and yellow-headed amazon.
The bristled grassbird is a small passerine bird in the genus Schoenicola. Also known as the bristled grass warbler, this species is endemic to the Indian subcontinent, where it is patchily distributed in Bangladesh, India, Nepal and Pakistan. These insectivorous birds skulk in dense and tall grasslands, often in marshy areas, habitats that are threatened by human activities. Formerly considered to be sedentary, the species may be migratory, moving south and east in the Indian peninsula during winter and returning to their breeding grounds in the northern plains south of the Himalayas.
Cincloramphus is a genus of birds in the grassbird family Locustellidae.
The little grassbird is a species of Old World warbler in the family Locustellidae. It is found in Australia and in West Papua, Indonesia. These sexually monomorphic birds are found in reed beds, rushes, lignum swamps and salt marshes of Southeastern Australia.
The striated grassbird is an "Old World warbler" species in the family Locustellidae. It was formerly placed in the family Sylviidae. It is now the only species placed in the genus Megalurus.
The fan-tailed grassbird or broad-tailed warbler is an African species of Old World warbler in the family Locustellidae. The species is closely related to the broad-tailed grassbird of India, and is sometimes treated as the same species, although a 2018 study found that it and the broad-tailed grassbird were not closely related, with the Indian species being a sister of Chaetornis striata.
Schoenicola is a genus of Old World warbler in the family Locustellidae. There are two species, both from peninsular India. The genus has been placed in the subfamily Megalurinae.
The broad-tailed grassbird is a species of Old World warbler in the family Locustellidae. It is endemic to the Western Ghats of India with a possibility of occurrence in Sri Lanka. A small, mostly brown bird, it has a broad rounded and graduated tail. It is found only on the higher altitude grassy hills where it usually skulks, except during the breeding season when males fly up into the air to sing in their display. The species is believed to be a resident although it is possible that they make local movements.
Locustellidae is a newly recognized family of small insectivorous songbirds ("warblers"), formerly placed in the Old World warbler "wastebin" family. It contains the grass warblers, grassbirds, and the Bradypterus "bush warblers". These birds occur mainly in Eurasia, Africa, and the Australian region. The family name is sometimes given as Megaluridae, but Locustellidae has priority.
Sylvioidea is a superfamily of passerine birds, one of at least three major clades within the Passerida along with the Muscicapoidea and Passeroidea. It contains about 1300 species including the Old World warblers, Old World babblers, swallows, larks and bulbuls. Members of the clade are found worldwide, but fewer species are present in the Americas.
The African warblers are a newly erected family Macrosphenidae, of songbirds. Most of the species were formerly placed in the Old World warbler family Sylviidae, although one species, the rockrunner, was placed in the babbler family, Timaliidae. A series of molecular studies of the Old World warblers and other bird families in the superfamily Sylvioidea found that the African warblers were not part of Sylviidae but were instead an early (basal) offshoot of the entire clade Sylvioidea. Some taxonomic authorities place the entire family Hyliidae here.
The jungle babblers, Pellorneidae, are mostly Old World passerine birds belonging to the superfamily Sylvioidea. They are quite diverse in size and coloration, and usually characterised by soft, fluffy plumage and a tail on average the length of their body, or longer. These birds are found in tropical zones, with the greatest biodiversity in Southeast Asia and the Indian subcontinent.
Ceratopipra is a genus of passerine birds in the family Pipridae.
Helopsaltes is a genus of passerine birds in the grassbird family Locustellidae.
