Population justification: The species is not uncommon in suitable habitat, within a very small range. A population estimate of 1,000-2,499 mature individuals seems appropriate, but this is provisional and requires confirmation. This equates to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals.
Trend justification: A slow and on-going population decline is precautionarily maintained owing to rates of habitat loss and degradation, however, it has been suggested that the population may in fact be stable (P. Pulgarin and O. Cortes in litt. 2012)
