Dicrourus [sic] densus
Formerly considered conspecific with D. hottentottus. Drongos inhabiting Lesser Sundas exhibit substantial morphological and vocal differences#R; more detailed studies, both of molecular genetics and of vocalizations, required. Preliminary analysis suggests that present species may contain 4–6 groups. Vocal analysis indicates considerable differences among races, although some taxa could perhaps be grouped on basis of morphological and vocal traits; recent field guide#R, however, treats every race as a full monotypic species, each being distinct in voice and morphology. Apparently no direct connection between race megalornis of present species and race amboinensis of D. bracteatus, despite extreme proximity of Gorong I (occupied by former) to E tip of Seram, in SE Moluccas (occupied by latter). Supposedly smaller race renschi (Sumbawa) treated as synonym of bimaensis, type locality of which is also Sumbawa. Six subspecies recognized.
