Population justification: This species is poorly known and the population size has not been quantified, but it is described as fairly common (Dutson 2011) and expert opinion suggests that the population numbers more than 1,000 mature individuals (G. Dutson in litt. 2016).

Trend justification: Remote sensing data (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein) indicate that in the ten years to 2020, forest loss in this species' range has been equivalent to c.4-6%. However, the population trend of this species is considered unknown given its apparent tolerance of degraded forest (Dutson 2011).
