Population justification: Population size not well known. Within its range lies c.4,000km² of suitable habitat (calculated using sRedList [2023], based on data from Jung et al. [2020]) and within this it remains regularly seen (eBird 2024) although is overall considered uncommon (Allen 2020). While its population size is not estimated, it is not suspected to be very small given the extent of available habitat.

Trend justification: Thought to be declining rapidly in response to habitat loss, with primary lowland forest bearing the brunt of Palawan's forest loss caused by logging, agricultural expansion and, in some years, typhoon damage. Trapping poses an additive but unquantified threat.

In the past three generations (13 years: 2010-2023), forest cover within this species' mapped elevational range decreased by c.23-25% with a considerable loss in 2022, when the effects of Super Typhoon Odette (also known as Typhoon Rai), which hit the island in December 2021, were first realised in remote sensing data (Global Forest Watch 2024, based on data from Hansen et al. 2013, and methods therein). Losses have been most acute in the extreme lowlands (<200m), where losses were approximately 25-28%, and it is these elevations that are suspected to host the majority of this species' population. Given this species is forest dependent, rates of forest cover loss are suspected, albeit with some inherent uncertainty, to be the best proxy for rates of population trend. Trapping and persecution is likely to have additive impacts on population declines, and while unquantified, is taken into account here. Accordingly, over the past three generations, this species is suspected of having declined by 25-35%.

Rates of average forest loss have increased since c.2016. While a substantial amount was lost because of Super Typhoon Odette, even before this annual rates 2016-2021 were almost a third higher than in 2011-2016. Accordingly, if this doesn't cease or slow (and especially if another powerful typhoon hits in this window), then rates of forest cover loss, and hence population reduction, may be higher in the future. Accordingly future rates of decline are suspected to be 25-39% over three generations.
