Population justification: The population size of this species has not been quantified, but it is described as uncommon and local.

Trend justification: Declines are thought to be occurring as a result of widespread forest destruction, although rates of decline are unlikely to be higher than moderate, as this species is tolerant of secondary and degraded habitats. The species is occasionally taken for the cagebird trade.
