Population justification: The population size of this species has not been accurately quantified. Although it is described as common (see Coates 1985, Pratt & Beehler 2015, Beehler & Pratt 2016), this species is confined to the small island of Numfor (335 km2) and as such is precautionarily suspected here to number fewer than 10,000 mature individuals.

Trend justification: This species can tolerate habitat degradation and has been recorded in well-vegetated gardens (Pratt & Beehler 2015, Beehler & Pratt 2016). There is however ongoing forest loss on the island, equivalent to c.5–8% over three generations (using Global Forest Watch 2022, based on Hansen et al. 2013). At least some of this forest loss amounts to total clearance for agriculture, where the kingfisher cannot persist. Given this species' dependence on some (if degraded) forested habitat, it is therefore suspected to be declining at an ongoing rate of 1–9% over three generations.
