Population justification: Lambert et al. (1993) estimated a maximum of 10,000 individuals, and so the population size is placed in the band 2,500-9,999 individuals here. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: The population is suspected to be in decline owing to trapping for the cagebird trade and habitat degradation from agricultural expansion and logging pressures.
