The Rondonia bushbird[note 1] (Clytoctantes atrogularis) is a Near Threatened species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds".

Adult males are mostly dark gray, with a hidden white patch between their shoulders and a slightly blacker bib.

[2] Since then it has been documented at additional sites between the rios Madeira and Sucunduri to its east in the state of Amazonas, and also in Mato Grosso.

It primarily inhabits lowland humid terra firme forest in locations with tangles of vines, a dense understory, and sometimes with Guadua bamboo.

The Rondonia bushbird's song is "tree-tree-tree, consisting of long sequences of regularly spaced, essentially identical whistled notes" that can be heard beyond 100 m (300 ft).

[4] The IUCN originally in 1994 assessed the Rondonia bushbird as Data Deficient, then in 2000 as Critically Endangered, in 2008 as Vulnerable, and since 2023 as Near Threatened.

[6] "Systematic survey works in Rondônia, Amazonas and Mato Grosso are urgently needed in order to locate any additional sites where this species may occur.
