Population justification: The global population is suspected to number c.100,000-1,000,000 individuals (Ferguson-Lees and Christie 2001), while national population estimates include: c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China; < c.100 breeding pairs, c.1,000-10,000 individuals on migration and c.50-1,000 wintering individuals in Taiwan; c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Korea; c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Japan and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009). A global population estimate of 100,000-1,000,000 individuals is roughly equivalent to 66,666 - 666,666 mature individuals.

Trend justification: The population is suspected to be declining due to forest loss across its range. Data from Global Forest Watch (2021) suggests that the rate of forest loss is likely to be <20% over three generations.
