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 New World warblers or wood-warblers are a group of small, often colorful, passerine birds that make up the family Parulidae and are restricted to the New World. They are not closely related to Old World warblers or Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores.
Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus. The genus was introduced by the German zoologist Friedrich Boie in 1826. The name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker".
The hooded warbler is a New World warbler. It breeds in eastern North America and across the eastern United States and into southernmost Canada (Ontario). It is migratory, wintering in Central America and the West Indies. Hooded warblers are very rare vagrants to western Europe.
The yellow-throated scrubwren is a passerine in the family Acanthizidae that is found in parts of eastern coastal Australia. It was formerly placed in the genus Sericornis, but is now the only species in the genus Neosericornis.
The African yellow warbler, Natal yellow warbler, dark-capped yellow warbler, or yellow flycatcher-warbler is a species of Acrocephalidae warblers; formerly, these were placed in the paraphyletic "Old World warblers".
The rusty mouse-warbler, is a species of bird in the family Acanthizidae. It is found in Indonesia and Papua New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The bicolored scrubwren or bicolored mouse-warbler is a species of bird in the family Acanthizidae. It is found in the New Guinea Highlands ; its natural habitat is subtropical or tropical moist montane forests.
The mountain mouse-warbler is a species of bird in the family Acanthizidae. It is found in Indonesia and Papua New Guinea, where its natural habitat is subtropical or tropical moist montane forests.
The fernwren is a species of bird in the family Acanthizidae. It is monotypic within the genus Oreoscopus.
The grey-green scrubwren is a species of bird in the family Acanthizidae. It is found in the highlands of New Guinea ; its natural habitat is subtropical or tropical montane forests.
Sericornis is a genus of small, mainly insectivorous birds, the scrubwrens in the family Acanthizidae. Despite the similarity in shape and habits, the true wrens (Troglodytidae) are a quite unrelated group of passerines.
The Papuan scrubwren is a species of bird in the family Acanthizidae. It is found in the highlands of New Guinea ; its natural habitat is subtropical or tropical moist montane forests.
The buff-faced scrubwren is a bird species in the family Acanthizidae. It is found in the highlands of New Guinea ; Its natural habitat is subtropical or tropical moist montane forests.
The Vogelkop scrubwren is a bird species in the family Acanthizidae. It is endemic to West Papua, Indonesia. Its natural habitat is subtropical or tropical moist montane forests.
The pale-billed scrubwren is a bird species in the family Acanthizidae. It is found in the Aru Islands and New Guinea. Its natural habitat is subtropical or tropical moist lowland forests.
Origma is a genus of passerine birds in the family Acanthizidae.
The spotted scrubwren is a bird species native to coastal southern Australia, from Adelaide westwards to Shark Bay in Western Australia. It was formerly considered conspecific with the white-browed scrubwren, and is known to hybridize with that species where their ranges overlap in the Adelaide area. Genetic analysis in a 2018 study of the family found that this taxon was more divergent from the white-browed scrubwren than the Tasmanian or Atherton scrubwrens and hence proposed its reclassification as a species. It was reclassified as a species in 2019.
Aethomyias is a genus of passerine birds in the family Acanthizidae that are endemic to New Guinea.
