Range
South America : Amazonia, East Brazil
Habitat
Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical swamps.
Reproduction
Nest is a bag like structure built 2-25 meter above ground. Often near a wasp nest, clutch size is 2 eggs, no further data.
Feeding habits
Forages alone or in pairs for insects. Prey is caught by short sallying form a perch. Will join miexed-species flocks.
Conservation
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Migration
Sedentary throughout range.
