The black-capped antwren is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Argentina, Bolivia, Brazil, and Paraguay.
Region
South America
Typical Environment
Occurs in northern Argentina, Bolivia, Brazil, and Paraguay, primarily in lowland and foothill habitats. It inhabits forest edges, gallery forests, secondary woodlands, and cerrado or scrubby woodland with a well-developed understory. The species favors midstory and canopy foliage for foraging but also uses dense understory in disturbed areas. It adapts well to mosaic landscapes, including regenerating forests and riparian corridors near savannas.

Ease of Keeping
Beginner friendly: 1/5
Despite the name, black-capped antwrens seldom follow army ant swarms like some other antbirds; they mostly glean insects from foliage. Pairs keep close contact with soft calls and often perform coordinated duets. They readily join mixed-species flocks in forest edges and secondary growth, which helps them find prey and avoid predators.
Temperament
active and wary
Flight Pattern
short rapid wingbeats
Social Behavior
Usually found in pairs or small family groups and frequently joins mixed-species flocks. Pairs maintain year-round territories and communicate with antiphonal duets. Nests are small cups placed in shrubs or low trees, with both parents involved in care.
Migratory Pattern
Resident
Song Description
A fast, high-pitched series of thin notes or trills, often delivered as a duet between mates. Calls include sharp chips and soft contact notes while foraging.
