Taxonomic note
Dicrurus ludwigii and D. sharpei were previously lumped as D. ludwigii (Handbook of the Birds of the World and BirdLife International 2022) but split following Fuchs et al. (2017, 2018) and Fishpool et al. (2021), who showed that sharpei is genetically diverged from ludwigii and that it differs morphologically in a number of ways, such as blue vs green sheen in both sexes (1); all-dark vs white-tipped underwing-coverts in both sexes (sometimes reported inversely, in error) (1); female as glossy as male vs less glossy than male (1); female close in size to male vs perceptibly smaller (on wing length at least 1); and almost squared-off vs more obviously forked tail in both sexes (1), as well as vocally. Suggestions that the recently described taxon occidentalis from W of the R Niger (Fuchs et al. 2018) might form a third species in the complex were rejected by Fishpool et al. (2021), who suggested that it is better treated as a subspecies of sharpei. Two subspecies recognised.

Population justification: It is considered fairly common in a variety of woodland, secondary and primary forest habitats and uses degraded forest and forest patches within agricultural areas. Densities were estimated at 7-8 pairs per square kilometer in Gabon (Brosset and Erard 1986), which would indicate that the global population is very large.
There are suspected to be at least three subpopulations, but likely fewer than 10. The two subspecies show considerable genetic divergence (Fuchs et al. 2018), and there may be two subclades within the western subspecies divided by the Dahomey Gap (Fuchs et al. 2018). The nominate subspecies contains two geographically isolated parts of the range in western Uganda (but these may be contiguous with those in South Sudan and DR Congo) and Kakamega forest in western Kenya (a site where a number of predominately western African species co-occur far to the east of their typical distribution). There may be further division within DR Congo, as it is unclear that the species occupies the whole range south to Upemba (Fishpool et al. 2021). It is suspected that there are at least three and no more than 10 subpopulations.
Trend justification: The area of forest cover within the range of the species is undergoing a moderately rapid reduction (7.1% forest cover loss [data from Global Forest Watch 2023]) over 3-generations. However, the species is tolerant of degraded forest and while it requires some wooded habitats, it favours edge and patchy habitats whose availability may have increased over this same time period. Consequently the impact of the current rate of forest cover loss on the population is unclear and the population trend is considered unknown.
