Population justification: The global population is estimated to number c.2,500-9,999 individuals (Population estimate derived from analysis of recent records and surveys detailed in BirdLife International 2001). This estimate equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals. National population estimates include: c.100-10,000 introduced breeding pairs in China; < c.100 introduced breeding pairs in Taiwan and < c.10,000 introduced breeding pairs in Japan (Brazil 2009).

Trend justification: A rapid and on-going population decline is inferred on the basis of trapping pressure for the international cage-bird trade.
