Population justification: The population size has been estimated to be as low as a few hundred pairs (Collar and van Balen 2002); however, it is easily overlooked, and there is still extensive forest east of Cibodas/Halimun that remains to be surveyed, thus it may be more common and widespread than recent observations suggest (B. van Balen in litt. 2013). It seems likely that more than 250 mature individuals occupy each of the large areas of forest at Gunung Gede and Halimun (C. Robson in litt. 2013). The species's population is therefore placed in the band for 2,500-9,999 mature individuals.
Trend justification: Although much of the population may now be restricted to protected areas on Java, it is suspected to be continuing to decline at a moderate rate, owing to the on-going encroachment of forests by agriculture and urban development, as well as limited trapping pressure (A. A. Supriatna in litt. 2012, B. van Balen in litt. 2013).
