Spot-winged Wood-Quail are birds that hide in ground vegetation and are often difficult to see since they are shy and skulk. This bird is the only representative of the genus Odontophorus found in the Atlantic Forest of eastern South America, where it occurs from eastern Brazil south to extreme northeastern Argentina. Its natural habitats are subtropical or tropical dry lowland forests. Bright red bare eyering and eyelid. Sides of head, malar region, chin, throat, breast and belly plain grey; overall colour brown to grey. Crest and crown chestnut; forehead and supercilium tawny. Their diet is made up of berries, also nuts of Araucaria on forest floor, and presumably some insects. Considered threatened in state of Minas Gerais and is virtually extinct in lowlands of Rio de Janeiro.
