Population justification: This species may require large areas of good quality habitat and thus have a small population, possibly below 10,000 individuals. It is placed in the band 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: The population is suspected to be declining owing to high rates of forest clearance within parts of its range.
