Population justification: The population is estimated to number 1,000-10,000 individuals, roughly equivalent to 670-6,700 mature individuals.

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction even thought it seems able to tolerate some habitat degradation and agricultural conversion (Ferguson-Lees and Christie 2001).
