The cryptic antthrush (Chamaeza meruloides), also known as Such's antthrush, is a species of bird in the family Formicariidae. It is endemic to the Atlantic Forest in southeastern Brazil. [2]
Although the cryptic antthrush was first described almost 200 years ago, it was long overlooked (hence, cryptic) due to confusion with the rufous-tailed antthrush (C. ruficauda) and short-tailed antthrush (C. campanisona), which are found in the same region. Its identity as a separate species was recognized in 1992. [3]
When Nicholas Aylward Vigors described this species in 1825, he based it on two specimens collected by George Such, and this is the reason for the species' other common name, Such's antthrush. [3]
The cryptic antthrush is 19 to 19.5 cm (7.5 to 7.7 in) long and weighs about 66 to 77 g (2.3 to 2.7 oz). The sexes are alike. Adults have a red-brown forecrown and brown crown. They have white or buff lores and a white streak behind their eye. Their upperparts are mostly olive brown with a reddish rump. Their tail is brown with a black band near the end and thin buffy tips on the feathers. Their throat is white or buffy white. Their underparts are mostly buffy white with black streaks on their sides and flanks and their crissum is deep buff. Their iris is brown to reddish brown, their bill dusky brown, and their legs and feet dusky brown. [4] [5]
The cryptic antthrush is found in the coastal mountains of southeastern Brazil from southern Bahia to northeastern Santa Catarina. It inhabits the floor of the interior and edges of humid montane forest. In elevation it mostly occurs between 200 and 1,500 m (700 and 4,900 ft) though occasionally lower. [4] [5] [3]
The cryptic antthrush is believed to be a year-round resident throughout its range. [4]
The cryptic antthrush's diet and foraging behavior are not known in detail. It is almost entirely terrestrial. It walks slowly and deliberately on the forest floor and along roots and logs while hunting for invertebrates. [4]
Nothing is known about the cryptic antthrush's breeding biology. [4]
The cryptic antthrush's song is "a long series of 20-40 hollow notes, loudest near the middle and quieter at the beginning and end". "One described call is an abrupt quick! note". [4]
The IUCN has assessed the cryptic antthrush as being of Least Concern. Its population size is not known and is believed to be stable. No immediate threats have been identified. [1] One researcher "found [the Cryptic] Antthrush in partially logged forest habitat, suggesting it may be tolerant of some level of human disturbance". [6]
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 cm in length, and are most closely related to the ovenbirds in the family Furnariidae, and the tapaculos in the family Rhinocryptidae. The family Formicariidae contains 12 species in two genera.
The black-faced antthrush is a species of passerine bird in the family Formicariidae. It is found in Central America from Honduras through Panama, on Trinidad, and in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay.
The streak-headed woodcreeper is a passerine bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Mexico, Central America, Brazil, Colombia, Ecuador, Guyana, Peru, Venezuela, and on Trinidad.
The dusky antbird or tyrannine antbird is a passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found from Mexico south through Central America and in Brazil, Colombia, Ecuador, French Guiana, Guyana, Suriname, and Venezuela.
The pinnated bittern, also known as the South American bittern, is a large member of the heron family (Ardeidae) found in the New World tropics. Like the other Botaurus bitterns, its plumage is mostly buffy-brown and cryptically patterned. Though it is a widespread species, it is rarely seen – presumably due to its skulking habits – and much about its life history remains little known.
The short-tailed antthrush is a species of bird in the family Formicariidae. It is found in every mainland South American country except Chile, French Guiana, and Uruguay.
Chamaeza is a genus of South American birds in the family Formicariidae.
The striated antthrush, sometimes called the noble antthrush, is a species of bird in the family Formicariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.
The rufous-tailed antthrush or Brazilian antthrush is a species of bird in the family Formicariidae. It is found in Argentina and Brazil.
Schwartz's antthrush, also known as the scalloped antthrush, is a species of bird in the family Formicariidae. It is found in Colombia and Venezuela.
The planalto woodcreeper is a sub-oscine passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Argentina, Brazil, Paraguay, and Uruguay.
The dusky-tailed antbird is an insectivorous bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Argentina, Brazil, and Paraguay.
The rufous-capped antthrush is a small species of bird in the family Formicariidae located in the order Passeriformes. It is considered to be uncommon but widespread, found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. The rufous-capped antthrush is typically found inhabiting the shady floor of tall, humid forests on solid ground, and is occasionally spotted in transitional forests (várzea) and savanna forests (Suriname).
The black-headed antthrush is a species of bird in the family Formicariidae. It is found in Colombia, Costa Rica, Ecuador, and Panama.
The rufous-fronted antthrush is a species of bird in the family Formicariidae. It is found in Bolivia, Brazil, and Peru.
The rufous-breasted antthrush is a species of bird in the family Formicariidae. It is found in Colombia, Costa Rica, Ecuador, Panama, Peru, and Venezuela.
The striated softtail is a Vulnerable species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to eastern Brazil.

The Mayan antthrush is a species of bird in the family Formicariidae. It is found in Belize, Guatemala, Honduras, and Mexico.
