Population justification: The species is described as locally common (Dutson 2011). On Tong, 40 individuals were seen in six hours in 1997 (G. Dutson pers. obs. 1997). The population size is suspected to fall into the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: Although it disappeared from Manus for unknown reasons during the last century, this species is currently not thought to be declining. Remote sensing data indicate minimal forest loss (<2%) in its range within the last ten years (Global Forest Watch 2022, using data from Hansen et al. [2013] and methods disclosed therein), and the species is tolerant of degradation. The population is tentatively suspected to be stable.
