Population justification: The global population size has not been quantified, but the species is described as generally uncommon, although locally common (Gibbs et al. 2001, Dutson 2011). It is described as being rare on Bougainville, as widespread and present at many localities on Santa Isabel, and as reasonably common on Kolombangara, Guadalcanal and San Cristobal (Baptista et al. 2020).

Trend justification: The population is suspected to be declining owing to forest loss and degradation. Remote sensing data (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein) indicate that in the three generations to 2021, forest loss in this species' range has been equivalent to c.7-9%. This may accelerate slightly (to a rate equivalent to 10-12% over three generations) in the future based on losses in 2016-2021, although the preferred steep hill forest is under less threat from logging and clearance and the species is thought to also occur in secondary forest (Dutson 2011). Hunting may be an additional threat; the current rate of decline is therefore tentatively placed in the range 1-19% over three generations.
