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.
Jerdon's nightjar is a medium-sized nightjar species native to southern India and Sri Lanka. Formerly considered as a subspecies of the long-tailed nightjar, it is best recognized by its distinctive call which sounds like a wooden plank being beaten periodically with each note ending in a quaver. The common name commemorates Thomas C. Jerdon who described the species.
The pheasant pigeon is a species of large terrestrial pigeon. It is the only species of the monotypic genus Otidiphaps. The pheasant pigeon is found in the primary rainforests of New Guinea and nearby islands. It ranges primarily over hilly and lower mountain areas, but can also be found in lowlands.
Cincloramphus is a genus of birds in the grassbird family Locustellidae.
The rufous songlark is a species in the family Locustellidae endemic to Australia.
The New Britain thicketbird or Bismarck thicketbird is a bird species. It used to be placed in the "Old World warbler" family Sylviidae, but it does not seem to be a close relative of the typical warblers; probably it belongs in the grass warbler family Locustellidae. It is found only in the rarely visited highlands of the island of New Britain in Papua New Guinea.
The Bougainville thicketbird is a bird species. It had been placed in the "Old World warbler" family Sylviidae, but it does not seem to be a close relative of the typical warblers; probably it belongs in the grass warbler family Locustellidae. It is endemic to Bougainville Island. Its natural habitat is subtropical or tropical dry lowland grassland. It used to be considered conspecific with the Santo thicketbird and the New Britain thicketbird.
The New Caledonia thicketbird or New Caledonia grassbird, is a bird species. Previously placed in the "Old World warbler" family Sylviidae, it does not seem to be a close relative of the typical warblers; probably it belongs in the grass warbler family Locustellidae. This species is endemic to New Caledonia.
The Fly River grassbird is a species of Old World warbler in the family Locustellidae. It is found in Indonesia and Papua New Guinea. Its natural habitats are freshwater marshes and lakes. It is threatened by habitat loss.
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 tawny grassbird is a large songbird that is part of the grass- and bush-warbler family (Locustellidae) commonly found in grassland and reedbed habitats. It is streaked above and has a distinctive rich brown cap. Its underside is paler and it has a long graduated tail. They call often with "loud, grumpy churring calls and a longer call that starts “tick-tick-tick-tick” and ends with an explosive descending trill".
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.
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.
The large-tailed nightjar is a species of nightjar in the family Caprimulgidae. It is found along the southern Himalayan foothills, eastern South Asia, Southeast Asia and northern Australia. This species is a resident of the countries of Australia, Bangladesh, Bhutan, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Pakistan, Papua New Guinea, Philippines, Singapore, Thailand, Timor-Leste and Vietnam. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, and subtropical or tropical moist montane forest.
The frilled monarch is a species of bird in the family Monarchidae. As currently defined, its range is restricted to forest on New Guinea and nearby smaller islands, but historically it has included some or all of the remaining members of the genus Arses as subspecies.
The olive-green camaroptera is a bird species in the family Cisticolidae.
The red-winged prinia or the red-winged warbler is a bird species in the family Cisticolidae. It formerly belonged in the monotypic genus Heliolais. It is found in Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Ivory Coast, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Malawi, Mali, Mozambique, Niger, Nigeria, Senegal, Sierra Leone, Sudan, Tanzania, Togo, Uganda, Zambia, and Zimbabwe, where its natural habitat is dry savanna.
The Guadalcanal thicketbird is a bird species. It used to be placed in the "Old World warbler" family Sylviidae, but it does not seem to be a close relative of the typical warblers; it belongs in the grass warbler family, Locustellidae. It is found on the island of Guadalcanal in the Solomon Islands.
