Population justification: The global population size has not been quantified, but the species is reported to be formerly very common (del Hoyo et al. 1994). Brazil (2009) has estimated national population sizes at <c.100 breeding pairs in China and c.100,000-1 million breeding pairs in Russia.

Trend justification: The population is suspected to have declined owing to over-hunting. However population declines may also be caused by natural fluctuations (del Hoyo et al. 1994).
