Population justification: The population size is preliminarily estimated to fall into 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 population decline is suspected based on rates of habitat loss estimated using time series satellite imagery (Renjifo et al. 2002).
