A large, very long-tailed dove with a dark chestnut-brown back, wings, and tail. Head, neck and underside contrastingly pale throughout range, either white (Moluccas and Biak) or pale gray (elsewhere). Juveniles are sooty above, brown below. Typically found singly, but sometimes in pairs or groups in fruiting trees. Inhabits subcanopy of forest and secondary growth from lowlands to mountains, but most abundant in the foothills. Size, shape, and bicolored appearance make it unique. Song comprises incessantly repetitive two-note “woo-wooook” phrases with a shorter first note and an upslurred second one.
