The plain-throated antwren is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.
Region
Amazon Basin
Typical Environment
Occurs widely in the lowland forests of Bolivia, Brazil, Colombia, Ecuador, and Peru. Prefers dense understory of terra firme forest, edges, and secondary growth, often near vine tangles and saplings. It forages from near ground level up to the mid-understory, keeping to shaded, cluttered microhabitats. Local presence can be patchy depending on understory structure but it is generally common where suitable habitat persists.

This small antbird is an understory specialist of Amazonian lowland forests and is often detected by voice before it is seen. Despite the name, it rarely attends army-ant swarms closely, instead gleaning insects quietly in pairs. It frequently joins mixed-species flocks moving through dense thickets.
Temperament
shy and skulking
Flight Pattern
short rapid wingbeats
Social Behavior
Usually found in pairs or family groups moving low in dense cover. Frequently joins mixed-species understory flocks but maintains tight pair bonds while foraging. Nests are placed low in shrubs or vine tangles; both sexes likely share incubation and care.
Migratory Pattern
Resident
Song Description
Song is a thin, rapid series of high-pitched notes that may accelerate slightly, carrying softly through the understory. Calls include sharp chips and soft contact notes used between pair members.
