Population justification: The population size has not been specifically estimated, but the species is reported to be uncommon (del Hoyo et al. 2001, Eaton et al. 2021). Although eBird (2022) data suggest that it is sparsely distributed, much of its range is totally inaccessible. Moreover, Actenoides kingfishers are elusive with low detectability (Fry and Fry 1999). Within its large range remains 25,000 km2 of forest, such that even if it does prove to occur at an unusually low density/occupancy, the population size is very likely to be above 10,000 mature individuals.
Trend justification: The population was previously suspected of undergoing sustained population losses because of habitat loss. However, recent remote sensing data (Global Forest Watch 2022, based on data and methods from Hansen et al. [2013]) suggest that in the three generations to 2021, this amounted to no more than 2% loss of forest cover extent. Future projections (Voigt et al. 2021) also show the majority of this species' range remaining intact up to 2050. Consequently, although the species is thought to be declining, it is suspected of doing so only very slowly.
