Population justification: The number of individuals has been estimated for about half of the global distribution in central and eastern Java. There, the population numbers 299-889 individuals, most likely not exceeding 1,000 individuals (Yuda 2008). Even though the potentially larger subpopulations on Bali are 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.
