Population justification: The global population size has not been quantified, but the species is described as rare or rarely seen (del Hoyo et al. 2005), while the population in China has been estimated at < c.100 breeding pairs (Brazil 2009).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and predation by introduced species.
