A large, front-heavy brown bird with a long, pale downcurved bill and a distinctive elongated head with a flat crown and a forehead tuft. Orange legs. Unmistakable males have a green-blue breast shield and long creamy-white plumes extending from the shoulders. Females are entirely earth-brown, lacking the shoulder extensions and shield. Immature resembles female. Found in canopy of tall forests in lowlands and foothills, confined to three islands in north Moluccas. Regularly sighted at known display sites. Very loud when displaying, giving raucous “WAA-WAA…” and “KEE-KEE…” notes.
