Large, terrestrial bird of flood-prone lowland rainforest; generally shy and difficult to see. Note all-dark appearance and small, red bill. Found in seasonally flooded forest, gallery forest in savanna, and near oxbow lakes. Forages on the ground for fallen fruit; usually alone or in pairs. Roosts in canopy and may flush into trees when disturbed. Told from other curassows in range by chestnut (not white) belly; Black Curassow is larger and has yellow knobs at base of bill. Song is a low humming, often given at night.
