Population justification: Fontaine (2003) suggests its population is 'not more than a few thousand individuals', and so it is tentatively placed in the band 1,000-2,499 individuals here. This is equivalent to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.

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