Population justification: It has a very small range, and appears to be rather scarce. The population is estimated to number 1,000-2,499 individuals, equating to 667-1,333 mature individuals, rounded to 600-1,500 mature individuals here. This requires confirmation.

Trend justification: A slow and ongoing population decline is suspected owing to rates of habitat loss.
