Population justification: A preliminary estimate is that the total population numbers fewer than 10,000 mature individuals, placed here in the band 2,500-9,999 mature individuals.

Trend justification: Despite its apparent tolerance of modified habitats, the species could be threatened by habitat loss at least in parts of its range. A slow decrease is suspected but it is uncertain whether a continuing decline can reasonably be inferred.
