Oriental Region : West, Central Java. It is found in Brunei, Indonesia, Malaysia, Myanmar, the Philippines, and Thailand


Its natural habitat is subtropical or tropical moist lowland forests. Prefers densde forest where it is found in the understorey. Also found in tree-rich scrubland, lime crags and mangroves.


Few data, builds a small cup from its own down, placed on a branch. Clutch size 1-2 eggs. Male incubates during the day, female during the dark hours.

Feeding habits

It feeds on insects which are taken by fluttering along branches and ground.


This species has a very 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.

The global population size has not been quantified, but the species is reported to be scarce throughout much of its range
