Population justification: The population size of this species has not been quantified; it is considered locally common.

Trend justification: A remote sensing study found that forest within the range of the species was lost at a rate of 16% over three generations (Tracewski et al. 2016). The species is additionally captured for the cagebird trade. However, as the species may be tolerant of secondary habitats, the rate of decline is believed to approach, but not meet, 30% over three generations.
