The narrow-billed antwren is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to eastern Brazil.
Region
Eastern Brazil, Atlantic Forest
Typical Environment
Found patchily in the Atlantic Forest of eastern Brazil, primarily in lowland and foothill evergreen and semi-deciduous forests. It favors dense understory, vine tangles, and forest edges, including secondary growth. The species also forages in thickets along streams and in selectively logged forest, provided sufficient understory remains. Fragmentation limits its occurrence to larger or better-connected forest remnants.

This small antbird is endemic to Brazil’s Atlantic Forest and is named for its slender, needle-like bill used to pick tiny arthropods from foliage. It often travels in pairs and joins mixed-species flocks, where its quiet trills can give away its presence in dense understory. Habitat loss and fragmentation are the main threats to this species.
Temperament
skulking yet active
Flight Pattern
short rapid wingbeats
Social Behavior
Typically found in pairs that maintain small territories and frequently join mixed-species flocks in the understory. Nests are small cups placed low in dense vegetation. Courtship includes soft calls and close-following through tangles.

Song Description
Delivers a series of soft, rapid trills and high, thin notes that can be easily overlooked amid forest background noise. Contact calls are sharp chips used to keep pairs in touch while foraging.
