Population justification: The population size is unknown, but the species has been considered rare for some time (Wells 2016). Recent records come from at least six sites with the potential to hold sustainable populations spread throughout Java (eBird 2016), however the species is now only infrequently observed at many sites where it was easy to see in the recent past (Eaton in litt. 2016).

Trend justification: The population is suspected to be undergoing a moderately rapid decline owing to capture for the cage bird trade, which may be exacerbated by past habitat loss in the lower elevation areas of the range.
