It is 50–60 cm long and weighs 100–128 g, waxy bluish-black with a long graduated tail tipped white, a prominent curved bill and a red face patch often bordered white. It breeds in primary forest, second growth, dense thickets, scrub, cultivated land and rubber plantations, and lives mainly on insects but also catches small lizards and small mammals.
