Population justification: The global population is estimated to number c.5,000-17,000 individuals, equivalent to c.3,300-11,000 mature individuals (Li Xiangtao and Liu Rusan 1993; Zhang Zhengwang 1998b; Zhang Zhengwang (verbally) 1999). The population in China has been estimated at <c.100 breeding pairs (Brazil 2009).

Trend justification: The species is suspected to be declining at a moderate rate, owing to the continuing loss and fragmentation of its habitat, particularly outside of protected areas, and also from reduced breeding success following human disturbance.
