Justification:
Listed as Endangered because of a serious population decline, estimated to be more than 50% over the last 10 years, inferred from land-use changes (as estimated from satellite imagery), observed shrinkage in distribution and rapid habitat destruction and/or degradation which will likely increase in the next 10 years.
