Population justification: This species is thought to have a moderately small population as it is a bird of lowland forest restricted to the island of Palawan. It is placed in the band 10,000-19,999 mature individuals, equating to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals. However, this is a preliminary estimate that requires clarification.
Trend justification: The population is suspected to be in slow decline owing to forest loss and degradation. The rate of decline is not thought to be more rapid because this species seems able to tolerate landscape-scale changes in habitats caused by human activities.
