as the north Philippine dwarf kingfisher. The two proposed species are differentiated by color and size: north Philippine dwarf kingfishers have dark blue spotted wings and ears and are slightly smaller than south Philippine dwarf kingfishers, which have a more noticeable lilac hue and are overall more uniform orange. In March 2020 a fledgling of the ''C. m. mindanensis'' subspecies was photographed for the first time by the Robert S. Kennedy Conservation Society led by Miguel David De Leon in Cagayan de Oro.

with the population believed to be on the decline. The Southern subspecies has a lower estimated population of 2,500 to 9,999 mature individuals with the Northern subspecies estimated at 10,000 - 19,999. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range. There are currently no targeted conservation plans for the species. It occurs in a few protected areas throughout its range like the
