A medium-sized bird of forest interior, from the foothill to the mid-mountains. An all-black bird with bluish gloss, long tail, flattened crown and hooked bill. Sits very upright in the midstory where it sallies to catch insects often disturbed by other species in mixed flocks. Very similar to a Spangled Drongo which it mimics the plumage of, but smaller and lacks a forked tail. Voice, a scratchy, drongolike song and a piercing, nasal “geh-geh-geh!” call.
