Population justification: The global population in 2006 was c.500 individuals (Unshan 2007), equivalent to c.330 mature individuals.

Trend justification: In 1981, only seven birds (including four adults) were known in the wild. By 2002, the wild population numbered 140 birds. The most recent population estimate is of c.500 individuals (Su Unshan 2007a), suggesting a very rapid increase (owing at least in part to conservation efforts), even though the distribution and population of this species is clearly now better known.
