The Bahia antwren or pileated antwren is a Vulnerable species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Brazil.
Region
Atlantic Forest of eastern Brazil
Typical Environment
Occurs in lowland and foothill Atlantic Forest along the eastern Brazilian coast, primarily in Bahia and extending into neighboring states. It favors forest edges, secondary growth, and well-structured evergreen forest, moving through the midstory and canopy. The species tolerates some disturbance if sufficient canopy connectivity remains. Fragmentation reduces occupancy, and it is largely absent from heavily degraded tracts.
Altitude Range
Sea level to 800 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
Also called the pileated antwren, this small antbird is restricted to Brazil’s Atlantic Forest, especially in Bahia and nearby states. Males and females look strikingly different and often perform coordinated duets. It forages actively in pairs and frequently joins mixed-species flocks. Habitat loss and fragmentation have led to ongoing declines.
Temperament
active and alert
Flight Pattern
short rapid wingbeats, darting between branches
Social Behavior
Usually seen in pairs that maintain small territories and often join mixed-species flocks while foraging. Nests are small cups placed in low to midstory vegetation. Both parents participate in incubation and feeding. Pairs remain closely associated year-round.
Migratory Pattern
Resident
Song Description
The song is a fast, high-pitched series of sharp notes and trills, often delivered as antiphonal duets between mates. Calls include dry chips and quick rattles used to keep contact in dense foliage.
