Population justification: Variably common, the species has declined to near (if not total) extinction on Lombok and Sumbawa. The total population is estimated to fall within the band 24,600-47,300 individuals.
Trend justification: The species is assumed to be experiencing a moderately rapid and on-going decline, owing to high trapping pressure for the cage-bird trade and continuing forest loss at lower altitudes within its range.
