Population justification: The global population size has not been quantified but is believed to be large given the range and frequency of records in suitable habitat. It is a forest-dependent species and appears to occur only in primary forest (eBird 2022). Within its range, the rate of forest conversion to plantations, primarily oil palm, has been very rapid over the past few decades (per Global Forest Watch 2022). There are recent records from remaining forested areas across the range, however the extent of suitable habitat is now considerably smaller than three generations ago. Where habitat is secure the species continues to be regularly observed (eBird 2022), though observing the species away from protected areas is becoming increasingly difficult. In Thailand, all recent records are in (/the vicinity of) the Hala Bala Wildlife Sanctuary (Treesucon and Limparungpatthanakij 2018) and the population there must now be very small. Almost all records in Malaysia now come from protected areas or forest concessions, and the population is thought to be declining rapidly in lowland Indonesia, although here (especially in Kalimantan), there are large tracts of suitable habitat remaining. Forest loss is much lower in Brunei, where impacts on the species may be much less severe and much of the forest here is likely to be suitable for this species. Overall, the population is considered highly unlikely to meet or approach the population size threshold for listing as threatened (<10,000 mature individuals) although this requires confirmation.
Trend justification: The species is most abundant in the undergrowth of intact primary lowland forest. Consequently the population impact of forest cover loss is expected to be equal to or greater than the rate of loss. In the three generations (15.15 years; Bird et al. 2020) to 2021, forest cover in this species' range was reduced by 24–27%, depending on the forest cover thresholds set (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). This value does not account for the impact of forest degradation, hence the population rate of reduction from habitat loss is likely to be greater than this. Similarly, since the species is most regularly encountered in low-lying forest (eBird 2022), where losses are greater, the overall rate of population reduction is suspected to be equivalent to c.25–35% over the last three generations. This rate is also precautionarily projected over the next three generations, although beyond that rates of loss may slow as the percentage area of forest outside protected areas diminishes.
