Population justification: The global population size has not been quantified, but the species is described as common (del Hoyo et al. 2007), while the population in Taiwan has been estimated at c.10,000-100,000 breeding pairs (Brazil 2009).
Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
