The slate-colored antbird is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, and Peru.
Region
Western Amazon Basin
Typical Environment
Occurs in the lowland rainforests of Brazil (western Amazon), Colombia (southeastern), Ecuador (eastern), and Peru (Amazonian). It inhabits dense understory of terra firme and seasonally flooded várzea forests, as well as river-edge thickets and old secondary growth. The species keeps close to the ground and lower midstory, moving through tangles and viney thickets. It is frequently associated with army-ant swarms and will also forage along forest streams and trails.

This antbird often attends army-ant swarms, snatching insects and other arthropods flushed by the ants, though it is not an obligate follower. Pairs are strongly territorial and frequently duet, creating an antiphonal song that helps maintain pair bonds. Males are slate-gray while females are rufous-brown, making the species notably dimorphic. It occupies dense understory in Amazonian lowland forests and is typically difficult to see but vocal.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats
Social Behavior
Usually encountered as pairs maintaining year-round territories in the forest understory. They follow army ants to feed and may form loose associations with other ant-following birds at swarms. Nests are typically placed low, and both sexes share incubation and chick-rearing duties.
Migratory Pattern
Resident
Song Description
Song is a series of clear, resonant whistles delivered in duets by the pair, often antiphonal with the female answering the male. Calls include sharp chips and scolds given when agitated near nests or at ant swarms.
