Population justification: The global population size has not been quantified, but the species is described abundant in many regions, such as Hong Kong (del Hoyo et al. 2005). National population estimates include: c.10,000-100,000 breeding pairs in China; c.100,000-1 million breeding pairs in Taiwan and c.100-100,000 breeding pairs in Japan (Brazil 2009).

Trend justification: The population is estimated to be increasing following range expansions in recent decades owing to habitat modification and degradation (del Hoyo et al. 2005).
