Population justification: Its population was initially estimated at 1,000-10,000 individuals, but it has subsequently been found at several more sites and may considerably exceed this upper limit. It is restricted to two or three forest blocks, that total an absolute maximum of 225,000 ha of suitable habitat, which, considering home range sizes of c.8-20 ha found in other tropical partridges, suggests that a total of 11,000-28,000 pairs might still be present, but hunting pressure and variable habitat quality could mean that numbers are much lower than this (B. van Balen in litt. 2012). On the basis of this information, its population is conservatively estimated to include 10,000-19,999 mature individuals.
Trend justification: Remaining forest continues to face logging pressure and the clearance of fragments is commonplace, whilst the species may also suffer some amount of hunting pressure; hence, it is suspected to be declining rapidly overall.
