Population justification: The global population size has not been quantified, but this species is described as common (Lloyd 2020).
Trend justification: Due to the remoteness and inaccessibility of large parts of its range, the species's habitat is currently not considered under imminent risk. Tree cover loss within the range is negligible (<1% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein); moreover, the species appears able to tolerate considerable habitat disturbance (Lloyd 2020). Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
