Population justification: The species is likely to have a population exceeding 2,500 mature individuals (L. F. Silveira in litt. 2012), and so it is placed in the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.
Trend justification: A rapid and ongoing population decline is suspected owing to rates of habitat loss.
