A rather large lory of lowland forest and semi-open areas. Mostly black with medium-length, rounded tail, reddish in the base and yellow undertail. Geographical variation and in some areas they have a reddish face, thighs and front of the underwing. Similar to Dusky and Yellow-streaked Lories in poor light. Black looks bigger-headed, is black-billed and has different flight. Yellow-streaked has little overlap but streaks should be visible even in flight. Loud and squeaky calls “kwik kwik!”. Other calls similar to a rusty door hinge.
