A slim and lustrous glossy-black flycatcher with upright posture, dark brown eyes, and a straight-edged square tail. Females are less glossy, and juveniles are spotted brown. Singles, pairs, or small groups frequent woodland, savanna, forest edge, and parkland, where they join mixed-species flocks. This species perches on branches and either pounces to the ground to hunt prey or pursues passing insects; it often associates with Fork-tailed Drongo, which it may imitate. The call is a three-note “tseeep-tsoo-tsoo.” The similar Fork-tailed Drongo differs by having red eyes and a forked tail, and Northern Black-Flycatcher differs by having dull matte black rather than glossy plumage.
