Population justification: The global population size has not been quantified, although the population in China has been estimated at fewer than 100 breeding pairs (Brazil 2009).
Trend justification: Precise data on trends are lacking, but slow to moderate declines are suspected to have occurred owing to a variety of human pressures.
