Large, dark, long-billed sunbird. The male has an iridescent blue patch on the forehead and throat, though this can be hard to see in poor light. The yellow shoulder tufts are usually hidden. The female is drab, but has a distinctively white-striped face. Found in the canopy of low- and middle-elevation rainforest. Distinctive call is a quick, descending series of several high notes. Male is separated from similar sunbirds by more restricted blue on the face.
