Population justification: The global population size has not been quantified, but the species is described as common in Hong Kong and Java and fairly common in southern China and south-east Asia (del Hoyo et al. 2005). Brazil (2009) has estimated the population in China at c.10,000-100,000 breeding pairs.
Trend justification: The population is suspected to be in decline owing to heavy trapping pressure, although the species remains common (del Hoyo et al. 2005).
