It can be found in the countries of Indonesia and East Timor. It was formerly considered to be conspecific with the hair-crested drongo (Dicrurus hottentottus). Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical moist montane forests. Conservation StatusThe Wallacean drongo has a very large range and does not approach the thresholds for Vulnerable under the range size criterion. Its extent of occurrence is greater than 20,000 km2. The population trend is not known but it is not believed to be declining sufficiently rapidly, and the population size is believed to be large enough for it to not qualify as Vulnerable using the population size criterion. For these reasons the species is classified as Least Concern by the IUCN.[2] SubspeciesThe following six subspecies are recognized:[3]
