Population justification: The global population size has not been quantified, but this species is described as uncommon to locally common in undisturbed forests (Short and Horne 2001).

Trend justification: The population trend has not been investigated, but the species' tolerance of a variety of forested, shrubby and secondary habitats near forest likely alleviate the impacts of deforestation (per Short and Horne 2001, Short and Kirwan 2020, eBird 2023). Within the range, 13% of tree cover has been lost over the past three generations (14.6 years); since 2017 this has been accelerating to a rate equivalent to 17% over three generations (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Given that the species however never moves far away from forest, it is tentatively suspected that population declines are roughly equivalent to the rate of tree cover loss, and they are therefore here placed in the band 10-19% over three generations.
