Population justification: The current global population is estimated to be 120,000 individuals (Lu 2004, del Hoyo et al. 2007).

Trend justification: Deforestation and habitat degradation are occurring within this species's altitudinal range, and a moderately rapid decline is suspected to be occurring in response. However it has recently been suggested that the species is not declining within its range (X. Lu in litt. 2016), further information is needed to confirm that the population is now stable. The trend is precautionarily treated as declining.
