This is an inconspicuous species of Sulawesi's montane and submontane forests, where it perches unobtrusively in the forest understorey (Fry and Fry 1999). It principally occurs at 900-2,000 m (Eaton et al. 2021), but was recorded as low as 250 m (White and Bruce 1986).

The species is endemic to Sulawesi, Indonesia. A. p. princeps occurs in north-east Sulawesi and A. p. regalis in south-east Sulawesi, while A. p. erythrorhamphus is more widespread in central, north-west and south-west Sulawesi (White and Bruce 1986, Fry and Fry 1999, del Hoyo et al. 2001). A sighting of an Actenoides kingfisher at Gunung Tumpu, in East Sulawesi (Rheindt et al. 2014) may be attributable to an undescribed taxon (or species). Notably, taxon regalis (sometimes afforded species rank: e.g., in del Hoyo et al. 2014) has not been seen since the collection of the two known specimens (a female and immature male) in December 1931, despite some moderate search effort (White and Bruce 1986, Berryman and Eaton 2020, eBird 2023, Rutt et al. in prep.).

Conservation and research actions underway
No specific action is known, although this species benefits from and occurs in numerous protected areas including Dumoga-Bone and Lore Lindu National Parks, and Gunung Ambang and Tangkoko Duasudara Nature Reserves.

Conservation and research actions proposed
Investigate the taxonomy of this complex to see if more than one species is involved. Undertake searches for A. p. regalis (Berryman and Eaton 2020) and the undescribed taxon from Gunung Tumpu (Rheindt et al. 2014) to clarify their status, distribution and taxonomy. Conduct repeated surveys of known and potential sites across Sulawesi in order to determine abundance and population trends. Conduct ecological studies to determine levels of tolerance of secondary habitats, particularly in areas where primary forests have been extirpated. Ensure the protection of existing forest reserves.
