Population justification: The global population is roughly estimated to be in the band c.2,500-9,999 mature individuals (BirdLife International 2001). This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals. National population estimates include: < c.1,000 individuals on migration and < c.1,000 wintering individuals in China; c.50-1,000 individuals on migration and < c.50 wintering individuals in Taiwan and < c.100,000 breeding pairs and < c.1,000 individuals on migration in Japan (Brazil 2009).
Trend justification: A moderate and on-going population decline is suspected to be occurring, as the species has become scarcer on its breeding grounds in Japan. Declines are likely to be occurring owing to habitat degradation and loss through agricultural intensification, as well as trapping for the cage-bird trade.
