Unique dark oriole with a restricted range: found only in montane and submontane forests in northwestern Borneo, primarily within the Paya Maga highlands of Sarawak state. Male is inky black all over with a slight blue gloss. Female has a gray belly. Both sexes have a bright red bill and dark rust-red vent. Forages quietly in the canopy, often alone, but sometimes in pairs or small groups. Short echoing song can be likened to “woo-wich’ew!”.
