The
drongos, subfamily
Dicrurinae, are a subfamily of small
passerine birds of the Old World tropics in the family
Dicruridae. Originally the family included the single genus
Dicrurus (subfamily Dicrurinae), but now it has been expanded to include the subfamilies Rhipidurinae (
Australasian fantails), Monarchinae (
monarchs and paradise flycatchers) and Grallininae (magpie-larks). The subfamily Dicrurinae contains two genera, the
monotypic Chaetorhynchus, and
Dicrurus, which contains about 25 species. The placement of the
pygmy drongo (
Chaetorhynchus papuensis) in the subfamily is in dispute on morphological and genetic grounds.
