Taxonomic note
Ceyx melanurus and C. mindanensis (del Hoyo and Collar 2014) were previously lumped as C. melanurus following Sibley and Monroe (1990, 1993).

Population justification: This species is poorly known. Described by Allen (2020) as local and uncommon, and the paucity of observations of this species in citizen science data (eBird 2024) would ostensibly suggest that it is a rare species. However, Ceyx are cryptic and have low detectability, with mist-netting often proving dwarf-kingfishers previously thought of as quite rare, to be quite common. This species' former conspecific, North Philippine Dwarf-kingfisher Ceyx melanurus, for example, similarly has fewer records in citizen science data, but was found to be common during mist-netting (e.g. Gomez et al. 2009). It seems likely therefore that Ceyx mindanensis is commoner than records suggest, especially given its tolerances of heavily degraded forest (see, e.g., de Leon et al. 2018). While its population size is therefore recorded as unknown, given the size of Mindanao (nearly 100,000 km²), the global population size is unlikely to be small.

Trend justification: The only plausible threat to this species is habitat loss and degradation. Although previously often regarded as dependent on virgin forest, it tolerates open forest and secondary growth, as do most Ceyx species (de Leon et al. 2018, Allen 2020). Global Forest Watch (2024, using data from Hansen et al. [2013] and methods disclosed therein) indicates that over the past 10 years, approximately 10-12% of forest canopy cover has been lost, but in many places this has been replaced with plantations which this species may inhabit, or may have overgrown. Accordingly, this value may not accurately reflect the population trend of this species, which is set to ongoing declines of 0-15% to account for considerable uncertainty.
