Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Benstead, P., Gilroy, J. & Taylor, J.
Justification:
This scarce forest-dwelling species is likely to be declining moderately rapidly throughout its range as a result of habitat loss. It is therefore considered Near Threatened.

Geographic Range [top]

Range Description: This species is confined to the Sundaic lowlands of south Tenasserim, Myanmar, peninsular and south-west Thailand, Sabah, Sarawak and Peninsular Malaysia, Kalimantan and Sumatra, Indonesia and Brunei, where it is generally uncommon (but possibly overlooked owing to its unobtrusive habits) (BirdLife International 2001).

Population [top]

Population: The population size of this species has not been quantified, but it has been described as generally uncommon.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species occurs in primary semi-evergreen and evergreen forests to 1,675 m asl, but usually below 600 m asl. It extends into secondary woodland and plantations in areas with adjacent primary forest.

Systems: Terrestrial

Threats [top]

Major Threat(s): Rates of forest loss in the lowlands of Indonesia have been extremely rapid, owing partly to the escalation of illegal logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas. Forest fires have also had a damaging effect (particularly in 1997-1998). The magnitude of these threats could have been allayed by this species's tolerance of hill forest, which is under less pressure from logging and agricultural conversion.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES II listed.

Conservation Actions Proposed
Monitor populations across the species's range to determine the magnitude of declines and rates of range contraction. Conduct studies to determine habitat associations and relative abundance in hill forest. Campaign for the protection of remaining tracts of lowland forest throughout the species's range.
