Listed as Near Threatened as this lowland forest dependent species occurs at low densities, and populations are estimated to have declined at a rate close to 30% over the last 15 years due to significant deforestation within its range, making it close to qualifying for Vulnerable under criterion A2c. This level of decline is predicted to continue due to ongoing deforestation.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This is a forest dependent species. Lekagul and McNeely (1977) reported that the type specimens were found roosting in an abandoned bird's nest (broadbill) in heavy forest on the bank of a river. A recent collection was found in Thailand in disturbed forest at 150 m asl which was adjacent to a large patch of pristine evergreen forest (Thong et al. 2006).
Systems: Terrestrial

Threats [top]

Major Threat(s): Deforestation due to logging, agriculture, plantations and forest fires represents a major threat to this species.

Conservation Actions [top]

Conservation Actions: This species is known from protected areas (Thong et al. 2006). It also appears on a checklist for the Bukit Barisan National Park in South Sumatra (O'Brien and Kinnaird 1996), but this record is questionable.
