Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. 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 number of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.
The family Vangidae comprises a group of often shrike-like medium-sized birds distributed from Asia to Africa, including the vangas of Madagascar to which the family owes its name. Many species in this family were previously classified elsewhere in other families. Recent molecular techniques made it possible to assign these species to Vangidae, thereby solving several taxonomic enigmas. The family contains 40 species divided into 21 genera.
The Madagascar lowland forests or Madagascar humid forests are a tropical moist broadleaf forest ecoregion found on the eastern coast of the island of Madagascar, home to a plant and animal mix that is 80 to 90% endemic, with the forests of the eastern plain being a particularly important location of this endemism. They are included in the Global 200 list of outstanding ecoregions.
The helmet vanga is a distinctive-looking bird of the vanga family, Vangidae, and is classified in its own genus, Euryceros. It is mainly blue-black, with rufous wings and a huge arched blue bill. It is restricted to lowland and lower montane rainforests of northeastern Madagascar. Its diet is composed of invertebrates, predominantly insects. The species is threatened by habitat loss.
The white-throated oxylabes is a species of passerine bird that is endemic to Madagascar. It is the only species placed in the genus Oxylabes. Formerly considered as a member of the Old World warbler family Sylviidae, it has been moved to the family Bernieridae — the Malagasy warblers. Its natural habitat is subtropical or tropical moist lowland forests.
The white-headed vanga is a species of bird in the family Vangidae. It is monotypic within the genus Artamella. It is endemic to Madagascar, where its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest.
The Madagascar blue vanga is a bird species in the family Vangidae. It is found in Madagascar, where its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
The sickle-billed vanga is a species of bird in the vanga family Vangidae. It is monotypic within the genus Falculea. It is endemic to Madagascar. Its natural habitats are tropical dry forests and tropical dry shrubland.
The nuthatch vanga, also known as the coral-billed nuthatch-vanga and formerly as the coral-billed nuthatch, is a species of bird in the family Vangidae. It is endemic to Madagascar.
The chabert vanga, also erroneously called "Chabert's vanga", is a species of bird in the family Vangidae. It is monotypic within the genus Leptopterus. The chabert vanga is the smallest bird in the vanga family when compared to the white-headed vanga and the blue vanga. Their biometrics are typically 14 centimeters in length and their weight ranges from 17 to 26.5 grams.
Crossley's vanga, also known as Crossley's babbler-vanga, Crossley's babbler, Madagascar groundhunter, or Madagascar groundjumper, is a bird species in the family Vangidae.
The northern dark newtonia is a species of bird in the family Vangidae. It is endemic to northeastern Madagascar. Its natural habitat is subtropical or tropical moist lowland forests.
Archbold's newtonia is a species of bird in the family Vangidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. The birds have a greyish brown back and tail, with a rufous forecrown and a buffy white belly, throat, and undertail coverts. They have a conspicuous rufous eye-ring, accompanied with a black bill and pale yellow eyes. The species is sexually monomorphic, and there is no major difference between the sexes. There is no breeding plumage for the males.
The common newtonia is a species of bird in the family Vangidae. It is endemic to Madagascar.
The red-tailed newtonia is a species of bird in the family Vangidae. It is endemic to Madagascar.
The Malagasy paradise flycatcher is a species of bird in the family Monarchidae. It is found in Comoros, Madagascar, and Mayotte. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
Zahamena National Park is a national park of Madagascar. Established in 1997, it covers an area of 423 square kilometres (163.32 sq mi) out of a total protected area of 643 square kilometres (248.26 sq mi). It is part of a UNESCO World Heritage Site, Rainforests of the Atsinanana, inscribed in 2007 and consisting of 13 specific areas located within eight national parks in the eastern part of Madagascar. In 2001, Bird Life International assessed avifauna of 112 species of which 67 species are exclusively endemic to Madagascar.
The rufous-bellied helmetshrike or Gabon helmetshrike is a passerine bird belonging to the Vanga family, Vangidae. It inhabits tropical forest in Central Africa. It is sometimes included within the chestnut-bellied helmetshrike of West Africa.
The southern dark newtonia is a species of bird in the family Vangidae. It is endemic to the montane forests of southeastern Madagascar, from Andringitra south to Tolagnaro. It was formerly considered a population of the dark newtonia, but was split from it in 2018 and classified as a distinct species after an analysis of physical and genetic differences from N. amphichroa, most notably its longer tail. However, some authorities such as The Clements Checklist of Birds of the World have supported tentatively classifying N. lavarambo as a subspecies of N. amphichroa rather than a distinct species.
The Comoros blue vanga or Comoro blue vanga is a bird species in the family Vangidae. It is found in the Comoros, where its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
