Population justification: The global population size has not been quantified, but with a potential range over at least 400,000 km2 of forest the total population must likely be in the thousands (Ferguson-Lees and Christie 2001).

Trend justification: There are no data on population trends; however, the population is suspected to be declining as a result of logging. The likely rate of decline remains unquantified.
