Population justification: The global population is estimated to number c.1,000-10,000 individuals (Ferguson-Lees et al. 2001), while the populations in China has been estimated at < c.100 breeding pairs (Brazil 2009).
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
