A large, black ground bird of lowland and foothill forests. Red-orange bill, yellowish head, yellow eye and orange legs. Co-occurs with Wattled Brushturkey on Misool Island but Red-billed occurs at lower elevations and has orange legs. Similar to Yellow-legged Brushturkey but Red-billed is usually higher and lacks the bright yellow legs. Much more often heard than seen. The voice is loud, raucous, 3-note “wok-wak! wak!” with the first note lower and a gap between the second and third notes.
