Population justification: The population size of this species has not been quantified, but it is described as locally very common on high mountain tops in Sumatra. This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 3.8% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction being less than 5%.
