Population justification: The number of individuals has been estimated for about half of the global distribution, the central and eastern Java populations. These number 299-889 individuals, most likely not exceeding 1,000 individuals (Yuda 2008). Even though the potentially larger subpopulation on Bali is not included in this estimate, it is very likely that the global population does not exceed 1,500-3,750 individuals in total. The population size is therefore placed in the band of 1,000-2,499 mature individuals. Throughout its range, the population is highly fragmented.

Trend justification: A rapid and on-going population decline is inferred on the basis of trapping pressure from the Asian songbird trade. The rate of the reduction is suspected to have been very rapid for a time between the 1960s and 1980s (BirdLife International 2001), and the species disappeared from many previously occupied sites during this period. Muchtar and Nurwatha (2001) revisited 64 known sites, finding the species still present at only 17. In Yogyarkarta province, surveys in 2017-18 of previously occupied sites revealed the loss of the species from 9/14 sites, several of which held the species at least as recently as 2005 (Rosyadi et al. 2019).

Yuda (2008) estimated that 38% of adults had been trapped in both 2004 and 2005 in central and eastern Java, a rate considered sufficient to drive rapid population reductions despite the species reasonably high fecundity. On Bali, rates of trapping are uncertain, as are the trends in trapping across the range. Many are bred in captivity and this makes estimating the scale and impact of trapping from the wild population highly uncertain. It is inferred that the current rates are sufficient to be driving a continuing population decline, but the rate of this decline is presently unknown.
