Population justification: Given the lack of recent records, any remaining population is precautionarily inferred to be extremely small, and a preliminary estimate places the population in the band 50-249 mature individuals.

Trend justification: Rates of forest loss in Java have been rapid and are continuing, hence the population is suspected to be declining rapidly as a result.
