Population justification: The global population size has not been quantified, but the species is described as generally local and uncommon (Dutson 2011), though likely to exceed 10,000 mature individuals (G. Dutson in litt. 2023). It is common at least on Makira, Kolombangara, Guadalcanal and Bougainville, although uncommon on Santa Isabel (del Hoyo et al. 1997, Collar and Boesman 2021).
Trend justification: There are no data on population trends; however, 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.5-6%. The species is more common at higher elevations and occurs in secondary forest and plantations, however, the rate of deforestation does not take into account logging and other degradation which may be driving declines (G. Dutson in litt. 2023). The cage-bird trade could threaten populations, although the severity of this threat is unclear. The population trend is therefore tentatively suspected to be declining, placed here in the range 1-9% within three generations.
