Population justification: The global population is estimated to number c.200,000-2,000,000 individuals (Wetlands International 2006), while the population in China has been estimated at <c.100 breeding pairs (Brazil 2009).

Trend justification: The overall trend is suspected to be decreasing (Wetlands International 2006).
