Population justification: The population is estimated to number 2,500-9,999 mature individuals, based on the analysis by BirdLife International (2001) that the population numbers at least several hundred, and very possibly several thousands. This estimate equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.

Trend justification: Information on the species's population status is lacking, but a negative slow to moderate trend is precautionarily suspected, as some habitat degradation is thought to be occurring within its range.
