Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Benstead, P., Gilroy, J., Taylor, J.
This species is listed as Near Threatened because it has a small range, in which the extent and quality of habitat are in decline, although its population is not regarded as severely fragmented or restricted to a few locations, and it probably has a moderately small population, which is also likely to be in decline.

Geographic Range [top]

Range Description:Harpactes whiteheadi is restricted to Bornean mountains, including Mt Kinabalu, Sabah, and Mt Dulit, Sarawak, Malaysia, and Gunung Lunjut, Kalimantan, Indonesia (BirdLife International 2001). It is apparently uncommon everywhere and reputedly declining on Kinabalu, for unknown reasons.

Countries occurrence:
Indonesia; Malaysia
Additional data:
Continuing decline in area of occupancy (AOO):Yes
Extreme fluctuations in area of occupancy (AOO):NoEstimated extent of occurrence (EOO) - km2:57900
Continuing decline in extent of occurrence (EOO):YesExtreme fluctuations in extent of occurrence (EOO):No
Continuing decline in number of locations:Unknown
Extreme fluctuations in the number of locations:NoLower elevation limit (metres):900
Upper elevation limit (metres):1500

Population [top]

Population:The global population size has not been quantified, but the species is described as uncommon throughout its limited range (del Hoyo et al. 1999).

Trend Justification:  Data on overall population trends are lacking, but declines have been reported at some sites (e.g. Mt Kinabalu, Sabah) and habitat loss at lower elevations could be impacting populations in parts of the range, thus a slow population decline is suspected.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:UnknownContinuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:This species is restricted to primary hill and montane forest at 900-1,500 m. It frequents dark, wet and mossy areas in higher branches of the understorey.

Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):7.3
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Habitat loss due to logging and agricultural conversion in its lower elevation range may be a threat, but reasons for declines at higher elevations are unknown.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
No targeted conservation actions are known for this species.

Conservation Actions Proposed
Carefully monitor populations at known sites in order to evaluate trends. Ensure the protection of montane forests, particularly on the lower slopes of key sites.
