Population justification: The global population size has not been quantified, but the species is reported to be abundant over most of its range (del Hoyo et al. 1999), while national population estimates include: c.10,000-100,000 breeding pairs in China; c.10,000-100,000 breeding pairs in Taiwan; < c.100 breeding pairs and < c.50 individuals on migration in Korea and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Japan (Brazil 2009).

Trend justification: The population is suspected to be increasing owing to a range expansion following a similar expansion by its hirundine hosts (del Hoyo et al. 1999).
