Justification of Red List category
This species has a 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over three generations). The population size is unknown, but is not suspected to be sufficiently small 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.

Population justification
The population size of this species has not been estimated, nor has a population density been compiled. However, there is approximately 22,000 km² of forest at a suitable elevation in its range (per Global Forest Watch 2022) and it does not appear to occur at an atypically low density (eBird 2022).

Trend justification
Data on this species are lacking, however the most likely threat, tree cover loss, has been minimal over the past 20 years and much of the range now lies in protected areas (e.g. Kinabalu Park, Crocker Range, Gunung Mulu National Park and Kayan Mentarang). In the three generations (11.25 years; Bird et al. 2020) to 2021, forest cover loss was equivalent to 4–5% depending on the forest cover thresholds set (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). Consequently, although suspected to be declining, rates of decline are thought to be slow, set here in the band 1–9% over three generations.

Harpactes whiteheadi is endemic to Borneo, where it most commonly observed in Sabah and Sarawak, Malaysia but also occurs in Kalimantan, Indonesia.

This species is restricted to primary hill and montane forest at 900-1,500 m (Eaton et al. 2021). It frequents dark, wet and mossy areas in higher branches of the understorey.

Habitat loss due to logging and agricultural conversion in its lower elevation range is a threat thought to be causing slow rates of decline.

Conservation Actions Underway
No targeted conservation actions are known for this species but it occurs in many protected areas (UNEP-WCMC and IUCN 2023).

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.
