A slim, medium-sized drongo with evenly gray plumage that is almost black in the western parts of its range and quite pale in the eastern parts of its range. It has a long slim tail with a deep fork. Common in wooded habitats where it sallies for insects and aggressively chases other birds that may compete for food or nectar. Most birds migrate south every winter. Similar to Black Drongo, but slimmer and usually in different habitats. Calls include harsh and sweet notes, and can mimic some bird species poorly.
