Population justification: The global population is estimated to number c.130,000-1,100,000 individuals (Wetlands International 2006), while the population in China has been estimated at <c.100 breeding pairs (Brazil 2009).
Trend justification: The overall population trend is fluctuating, although some populations are stable and others have unknown trends (Wetlands International 2006).
