Population justification: The species remains relatively common in some areas, but the global population is thought to be moderately small. It is estimated to number 10,000-19,999 individuals. This roughly equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend justification: The population is suspected to be in decline due to trapping for the cagebird trade and loss and degradation of its habitat, but the trend has not been directly estimated. Tracewski et al. (2016) measured the forest loss within the species’s range between 2000 and 2012 as c. 35 km². Assuming that forest loss continues at the same rate to the present day, this roughly equates to a rate of forest loss of 7.8% over the last three generations (22.5 years). The species tolerates a certain level of habitat modification, so that the conversion of forests might affect the species less severely than feared.
