The harlequin antbird is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Brazil.
Region
Amazon Basin
Typical Environment
Occurs in lowland terra firme rainforest of the central Brazilian Amazon, favoring mature, undisturbed forest with dense understory. It keeps close to the forest floor and mid-understory, tracking columns of army ants through shadowy gullies and ridges. It avoids open edges and heavily degraded habitats. Protected forest tracts and continuous canopy are important for its persistence.
Altitude Range
Sea level to 600 m
Climate Zone
Tropical
Ease of Keeping

The harlequin antbird is an obligate army-ant follower, snatching insects and other arthropods that fleeing swarms flush from the leaf litter. Males and females look markedly different, giving rise to the 'harlequin' name due to the male’s striking patterning. It keeps to dense understory, making it more often heard than seen. Habitat loss in the Brazilian Amazon is its primary threat.
Temperament
secretive and territorial
Flight Pattern
short rapid wingbeats
Social Behavior
Usually found in pairs or small family groups within a home range, closely attending army-ant swarms. Pairs maintain territories and communicate with duet-like calls. Nesting is thought to be a simple cup placed low in dense vegetation, with biparental care typical of antbirds.
Migratory Pattern
Resident
Song Description
A series of sharp, piping whistles that accelerate slightly, often delivered as a duet. It also gives dry scolds and chatter around ant swarms.
