Population justification: The global population size has not been quantified, but the species is not described as common within any part of its small range (del Hoyo et al. 1994). Brazil (2009) has estimated national population sizes at <c.100 breeding pairs in China and c.10,000-100,000 breeding pairs in Russia.

Trend justification: There are no data on population trends; however, the species is suspected to be in decline owing to hunting and habitat loss and degradation.
