Population justification: The global population size has not been quantified, but the species is described as common throughout its range and abundant in lowland and mid-altitude areas of Borneo (del Hoyo et al. 2005).

Trend justification: The population is suspected to be increasing rapidly as this species benefits from deforestation and the creation of artificial habitats (del Hoyo et al. 2005).
