Population justification: Karakelang, where the vast majority of the species's population is found, was estimated to hold 8,230-21,400 birds in 1999. The estimate of 8,200-21,400 individuals is used as a total here, roughly equating to 5,500-14,000 mature individuals.
Trend justification: Agricultural encroachment and logging are driving forest loss which is compounding the threat of illegal trade in the species, hence it is suspected to be declining rapidly.
