Population justification: The global population size has not been quantified, but the species is described as uncommon to locally common (del Hoyo et al. 2006), while the population in China has been estimated at c.100-10,000 breeding pairs (Brazil 2009). The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
