Population justification: The population size has not been quantified, but recent surveys suggest that the species is generally uncommon (F. Angulo Pratolongo in litt. 2012). In view of the very small range, the population is here tentatively placed in the band 1,000-2,499 mature individuals, but an accurate quantification is urgently required.

Trend justification: The population trend has not been estimated directly. The only threat known to the species is the loss and degradation of its habitat. Forest loss within the range has been very low over the past ten years (<2%; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is strictly dependent on forest, and as such a population decline of 1-9% over ten years is precautionarily suspected.
Deforestation however appears to be increasing rapidly in areas just below the altitudinal range of the species (Global Forest Watch 2021). Continuing encroachment and logging of forests near the two sites from which the species is known is likely to put increasing pressure on the habitat in the near future and therefore, the rate of population decline may increase. The rate of future decline is therefore placed in the bans 1-19% over the next ten years.
