South America : South, West, Northeast Amazonia
Habitat
This species is common in tangled lianas and shrubs along the edges of forests and in capoeiras with trees. It lives in pairs, hidden in dense vegetation close to the ground.
Reproduction
No data.
Feeding habits
Forages in small (probably) family groups low above ground, 0-5 meter. Actve and methodical forager hopping, scanning and catching insects, mostly spiders. Often perch gleans prey from leafs.
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.
