Population justification: This species's population was previously estimated at fewer than 10,000 mature individuals by McGowan and Garson (1995). Densities recently calculated in Puerto Princesa Subterranean River National Park suggest that the figure given by McGowan and Garson (1995) is likely to be an underestimate, based on estimated forest coverage on Palawan. However, the latest density estimates are unlikely be representative of the whole island. With this in mind, the species's population is conservatively placed in the band 20,000-49,999 individuals.
Trend justification: Logging and clearance of lowland forest has been extensive on Palawan and continues, with many areas falling within mining designations. Hunting pressure is also severe in places. As a result the species is suspected to be declining rapidly.
