Population justification: The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Trend justification: N. Brickle in litt. (2004) and J. Eames in litt. (2004) argue that there is little to suggest that the overall population is in decline, although the species is threatened by locally high hunting pressure and continuing habitat loss, thus a moderately rapid decline is precautionarily suspected.
