Population justification: The population size has not been quantified, but the species appears to be rather scarce (per eBird 2023). Based on the very small range, the population is precautionarily suspected to number less than 10,000 mature individuals, but an accurate estimate of the population size is urgently required.

Trend justification: The population trend has not been investigated, but the species at present appears secure and not under imminent risk. Tree cover loss is very low within the range (1% over three generations) and vast areas of pristine forest remain near occupied sites (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Despite the species' strong dependence on dense montane forests, this low rate of habitat loss is currently not thought to affect the population. It is therefore suspected to be stable.
