Population justification: The population size is unknown, but the species is described as uncommon (Allen 2020).

Trend justification: The species is most abundant in lowland primary forest and mature secondary forest, with populations occurring at half-density in early-stage secondary forest (Mallari et al. 2011) and scarcely at all in cultivation and open country. Global Forest Watch (2021, using Hansen et al. [2013] data and methods disclosed therein) data indicate that c.20% of forest cover (with greater than 30% canopy cover) has been lost over the past 10 years. This value does not account for additional impacts and losses caused by forest degradation, which is pervasive in Palawan's lowlands, such that the population is suspected of declining at a rate greater than 20% over 10 years.
