This species has been uplisted to Endangered on the basis that its declining population is estimated to be very small, with fewer mature individuals than previously thought. The destruction of its montane forest habitat, as well as direct human persecution, are inferred to be driving a continuing decline. Further research is required to elucidate threatening processes and quantify their resulting effects on population trends. The IUCN Red List of Threatened Species.
