Population justification: The global population size has not been quantified, but the species is reported to be fairly common to common (Harrap and Quinn 1996), 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 stable in the absence of evidence for any declines or substantial threats.
