The tapaculos or tapacolos are a family, Rhinocryptidae, of small suboscine passerine birds, found mainly in South America and with the highest diversity in the Andean regions. Three species are found in southern Central America.
Formicariidae is a family of smallish suboscine passerine birds of subtropical and tropical Central and South America known as antthrushes. They are between 10 and 20
Scytalopus is a genus of small suboscine passerine birds belonging to the tapaculo family Rhinocryptidae. They are found in South and Central America from Tierra del Fuego to Costa Rica, but are absent from the Amazon Basin. They inhabit dense vegetation at or near ground-level and are mainly found in mountainous regions, particularly the Andes. They can be very difficult to see as they run through the undergrowth in a mouse-like fashion.
The crescentchests are a genus, Melanopareia, of suboscine passerine birds from South America. The genus has long been placed with the tapaculos in the family Rhinocryptidae. Their placement there has been questioned and in 2007 the genus was placed in its own family, Melanopareiidae, by the South American Classification Committee. Subsequently, the family was accepted by the International Ornithological Congress Bird List and the Clements Checklist. The family Melanopareiidae was formally erected in 2009.
The olive-crowned crescentchest is a species of bird in the family Melanopareiidae. It is found in Argentina, Bolivia, and Paraguay.
The black-throated huet-huetSpanish pronunciation:[wetwet], is a species of bird in the family Rhinocryptidae. It is found in southern/central Chile and adjacent western Argentina. Its natural habitat is temperate forest.
Scelorchilus is a genus of bird in the family Rhinocryptidae.
The chucao tapaculo is a species of bird in the family Rhinocryptidae. It is found in central Chile and adjacent Argentina; it has also been recorded in Chile's Magallanes Province.
The Caracas tapaculo is a species of bird in the family Rhinocryptidae. It is endemic to Venezuela.
The Chocó tapaculo is a species of bird in the family Rhinocryptidae. It is found in Colombia, Ecuador, and Panama.
The trilling tapaculo is a species of bird in the family Rhinocryptidae. It is found in Bolivia and Peru.
The mouse-coloured tapaculo or Serra do Mar tapaculo is a species of bird in the family Rhinocryptidae. It is endemic to humid highland forests in southeastern Brazil, where it ranges from southwestern Espírito Santo to northeastern Rio Grande do Sul. Most of its range is in the Serra do Mar, but it also occurs further inland in Paraná and Santa Catarina. Until 2005, the Planalto tapaculo was included in the mouse-coloured tapaculo.
The Ecuadorian tapaculo or El Oro tapaculo is a small passerine bird belonging to the genus Scytalopus, a genus of tapaculos. It is restricted to a small area in south-western Ecuador and was not described until 1997.
The Vilcabamba tapaculo is a small passerine bird in the family Rhinocryptidae. It is endemic to Peru.
Eleoscytalopus is a genus of tapaculos found in lowland Atlantic forest of eastern Brazil. Until recently, they were included in the genus Scytalopus, but the two species are actually closer to the bristlefronts. Unlike the members of the genus Scytalopus, the members of Eleoscytalopus have largely white underparts and bluish-grey upperparts. The voices of the members of the two genera also differ.
The Paramillo tapaculo is a species of bird in the family Rhinocryptidae.
The rock tapaculo or Espinhaço tapaculo is a species of bird in the family Rhinocryptidae. It is endemic to altitudes of 900–2,100 metres (3,000–6,900 ft) in the central and southern Espinhaço Mountains, and the Mantiqueira Mountains in Minas Gerais, Brazil, though it may also occur in adjacent parts of Rio de Janeiro and São Paulo. It is found in shrubby and grassy habitats in rocky regions, and in elfin and cloud forest. It closely resembles the Diamantina tapaculo and Planalto tapaculo in appearance and voice.
Tyrannides is a clade of passerine birds that are endemic to the Americas. This group is divided into two clades that contain eleven families. The families listed here are those recognised by the International Ornithologists' Union (IOC).
The Bahian mouse-colored tapaculo or Boa Nova tapaculo is a species of passerine bird native to Bahia, Brazil.
The Perijá tapaculo is a species of passerine bird in the family Rhinocryptidae (tapaculos). Endemic to the Serranía del Perijá mountain range on the Colombia–Venezuela border, the Perijá tapaculo is found at altitudes of 1,600–3,225 metres. Its body is 10 to 12 centimetres long and its tail is about 4 cm (1.6 in) long. Specimens have long been stored in museums, but the species was described only in 2015 based on sixteen specimens found between July 2008 and February 2009. It is considered vulnerable to extinction.
