Sunlight can bring a blue-green sheen to its black plumage, and its long tail is deeply forked. It hunts insects from perches in savanna and open woodland.
Adults have black plumage that can shine blue or blue-green in good light, a long forked tail, and red eyes. Juveniles are browner and have a shallower tail fork.
It often watches for prey from a perch, then catches much of it on the ground. Insects make up most of its diet, with small fish and flower nectar taken occasionally.
