Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International

Facilitator/Compiler(s): Benstead, P., Gilroy, J., Taylor, J.
This species occurs in lowland evergreen forest in a region in which deforestation is occurring at a rapid rate. It is therefore likely to be undergoing a moderately rapid population decline, and should be monitored carefully. On this basis it is considered Near Threatened, but is not regarded as more threatened owing to its tolerance of some modified habitats.

Previously published Red List assessments:
2008 Near Threatened (NT)
2004 Near Threatened (NT)
2000 Lower Risk/near threatened (LR/nt)
1994 Lower Risk/near threatened (LR/nt)
1988 Lower Risk/least concern (LR/lc)

Population [top]

Population: The population size of this species has not been quantified; it is considered scarce to common throughout its range.

Trend Justification:  A moderately rapid population decline is suspected to be on-going as a result of continuing forest loss and degradation across the species's range.
Current Population Trend: Decreasing
Additional data:
Number of mature individuals: Unknown Continuing decline of mature individuals: Yes
Extreme fluctuations: No Population severely fragmented: No
Continuing decline in subpopulations: Unknown
Extreme fluctuations in subpopulations: No All individuals in one subpopulation: No

Habitat and Ecology [top]

Habitat and Ecology: This species occurs in primary lowland evergreen forest up to 800 m asl. It is also found in tall secondary forest, poor-quality Dipterocarp slope forest and occasionally in rubber plantations.

Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 8.5
Movement patterns: Not a Migrant

Threats [top]

Major Threat(s): Rates of forest loss in the Sundaic lowlands 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 may be allayed by this species's tolerance of secondary and slope forest, although further studies are required to determine whether this species can genuinely persist in these habitats in the absence of adjacent primary habitat.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
No targeted conservation actions are known for this species, although it occurs in a number of protected areas.

Conservation Actions Proposed
Conduct repeated surveys across the species's range to determine the magnitude of declines and rates of range contraction. Conduct ecological studies to determine precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Campaign for the protection of remaining tracts of lowland forest throughout the species's range.
