The Acre antshrike is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil and Peru.
Region
Southwestern Amazon Basin
Typical Environment
Occurs in lowland rainforest along the Brazil–Peru border, chiefly in and around the Serra do Divisor (Brazil) and adjacent Sierra del Divisor (Peru). It favors dense, humid forest understory with vine tangles and thickets, including edges of terra firme forest and selectively disturbed or secondary growth. The species keeps to shadowy understory and lower midstory strata and is often associated with complex understory structure. Local presence may be patchy, tracking areas with dense thickets and broken canopy.

150–700 m

Acre antshrike is a recently described antbird restricted to the Serra/Sierra do Divisor region along the Brazil–Peru border. It forages quietly in dense understory, where it is easier to hear than see, and pairs often perform antiphonal duets. Like other antshrikes, it uses a strong hooked bill to pry insects from foliage and vine tangles.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats through dense cover
Social Behavior
Typically found as territorial pairs that skulk through understory tangles. Nests are placed low in dense vegetation, and both sexes participate in territory defense. It occasionally attends mixed-species flocks at the forest edge but usually forages independently or as a pair.
Migratory Pattern
Resident
Song Description
The song is a series of sharp, clear whistles that accelerate or slightly descend, often delivered as coordinated duets between the pair. Calls include dry ticks and scolding notes given from concealed perches.
