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 Old World babblers or Timaliidae, are a family of mostly Old World passerine birds. They are rather diverse in size and coloration, but are characterised by soft, fluffy plumage. These are birds of tropical areas, with the greatest variety in Southeast Asia and the Indian subcontinent. The timaliids are one of two unrelated groups of birds known as babblers, the other being the Australasian babblers of the family Pomatostomidae.
The wrentit is a small bird that lives in chaparral, oak woodlands, and bushland on the western coast of North America. It is the only species in the genus Chamaea.
The malia is a medium-sized babbler-like passerine. It has an olive-green plumage, yellowish head and chest, and pinkish-brown bill. The young is duller than the adult. It is the only member of the genus Malia.
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 red-collared babbler, also known as the red-collared mountain-babbler, is a passerine bird in the family Leiothrichidae. It is found in Burundi, Democratic Republic of the Congo, Rwanda, and Uganda. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Macronus, the tit-babblers, are a genus of passerine birds in the family Timaliidae. This genus's name is frequently misspelled as Macronous.
Micromacronus is a bird genus in the family Cisticolidae endemic to the Philippines. Long considered to be monotypic, its members are known as miniature babblers or miniature tit-babblers. As the scientific as well as the common names indicate, their habitus resembles a diminutive version of the tit-babblers (Macronus). The genus was only described in 1962, upon the description of the first species, which had been collected by collector Manuel Celestino and Godofredo Alcasid, a zoologist at the Philippine National Museum. The genus was formerly placed in the family Timaliidae but a molecular phylogenetic study published in 2012 found that the genus was more closely related to species in the family Cisticolidae.
Napothera is a genus of birds in the family Pellorneidae. Some of its species were formerly placed in the genera Rimator and Jabouilleia.
The Cordillera ground warbler, also known as Rabor's wren-babbler or the Luzon wren-babbler, is a species of bird currently placed in the family Locustellidae. It is endemic to the Philippines, where it is found in northwest Luzon in the foothills of the Cordillera Mountain Range.s natural habitat is tropical moist lowland forests. It was formerly conspecific and forms a species complex with the Bicol ground warbler and Sierra Madre ground warbler, which are some of most elusive birds in the country due to their extremely shy nature. Among these three elusive species, the Cordillera ground warbler is the rarest and most threatened. It has only been photographed once in the wild.It is threatened by habitat loss.
Pnoepyga is a genus of passerines endemic to southern and southeastern Asia. Its members are known as cupwings or wren-babblers. The genus contains four species. The genus has long been placed in the babbler family Timaliidae. A 2009 study of the DNA of the families Timaliidae and the Old World warblers (Sylviidae) found no support for the placement of the genus in either family, prompting the authors to erect a new monogeneric family, the Pnoepygidae.
Pseudoalcippe is a genus of passerine birds in the family Sylviidae that are found in Africa.
Stachyris is a genus of passerine birds in the Old World babbler family, Timaliidae.
Alcippe is a genus of passerine birds in the monotypic family Alcippeidae. The genus once included many other fulvettas and was previously placed in families Pellorneidae or Timaliidae.
Sterrhoptilus is a songbird genus recently separated from Stachyris. It used to be placed in the family Timaliidae. With other "Old World babblers" of the genus Yuhina, it was recently determined to be better placed in the family Zosteropidae.
Fulvetta is a genus of passerine birds. Originally proposed in 1877, it was recently reestablished for the typical fulvettas, which were long included with their presumed relatives in the Timaliidae genus Alcippe. But they are actually quite closely related to the parrotbills, and are thus now placed in the family Paradoxornithidae.
The Afghan babbler is a species of bird in the family Leiothrichidae. It is found from southeastern Iraq to south western Pakistan. It was formerly considered a subspecies of the common babbler.
The Bicol ground warbler is a species of passerine bird in the family Locustellidae. It is native to southern Luzon and Catanduanes in the Philippines. It was formerly conspecific and forms a species complex with the Cordillera ground warbler and Sierra Madre ground warbler, which are some of most elusive birds in the country due to their extremely shy nature. Its natural habitat is tropical moist lowland forest. It is threatened by habitat loss.
The Sierra Madre ground warbler is a species of passerine bird in the family Locustellidae. It is endemic to the island of Luzon in the Philippines, where it is found in the northeastern and eastern foothills of the Sierra Madre. Its habitat is in tropical moist lowland and the lower reaches of tropical montane forest. It was formerly conspecific and forms a species complex with the Cordillera ground warbler and Bicol ground warbler, which are some of most elusive birds in the country due to their extremely shy nature.While not officially threatened, its population is said to be declining due to habitat destruction through deforestation.
Gypsophila is a genus of birds in the family Pellorneidae.
