Population justification: The population is estimated at 1,000-2,250 individuals (although the upper bound may be as low as 2,000 individuals [R. Thorstrom in litt. 2016]), roughly equivalent to 670-1,500 mature individuals.

Trend justification: The population is suspected to be in decline owing to ongoing deforestation.
