Population justification: The total population is estimated to number 10,000-60,000 individuals, roughly equivalent to 6,700-40,000 mature individuals (O. Jahn in litt. 2009).

Trend justification: This species is suspected have undergone rapid declines during the past three generations (34 years) owing to hunting pressure and habitat loss and fragmentation, and these declines are predicted to continue.
