Population justification: Population estimate = 20 individuals/km² x 1,700 km² (20% of EOO) = 34,400 individuals (density range from up to lower quartile of two Asian congeners in BirdLife Bird Population Density Spreadsheet). Perhaps best currently placed in population band of 20,000-49,999 individuals.

Trend justification: Although data are very poor, the species may be declining owing to the bird trade.
