Population justification: Uncommon within a very small range, so placed in the band 1,000-2,499 mature individuals. This equates to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals. This is a provisional estimate that requires confirmation.
Trend justification: Although the status of this species is very poorly known, it is suspected that a slow decline may be occurring, owing to increasing habitat loss and degradation within its likely range.
