Justification of Red List category
This species is largely restricted to extensive tracts of primary evergreen forest within a region experiencing high rates of deforestation. Even though the species is widespread within its range, high hunting pressure is exacerbating the population decline caused by habitat loss. The species is thus suspected to undergo a large population reduction over the next three generations. Therefore, it is listed as Vulnerable.
