Population justification: This species is described as rare and essentially unknown; its population is placed in the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: This species's population is suspected to be declining slowly, in line with rates of habitat loss within its range.
