Range DescriptionCrax alector is found in north-central South America. Subspecies erythrognatha occurs to the west. In east Colombia it is locally abundant along the east Andes and Macarena Mountains, where it has been considered the most common large bird at an estimated density of 1/1.25 ha of forest. It also occurs in southern Venezuela. The nominate subspecies alector is found in the east. At its westernmost point, in Cerro de la Neblina, east Venezuela, it was considered much less common than another cracid, Razor-billed Curassow Mitu tuberosum, in 1991. Its range extends from there eastwards through Guyana, where it is common only where there is intact habitat and no hunting, and beyond. In Suriname it was considered common in 1968, but is only locally so now (del Hoyo et al. 1994, Restall et al. 2006); in French Guiana it is subject to heavy hunting pressure and in danger of extirpation. It has already been driven from areas around human settlement, but does exist at optimal density (8/100 ha) in areas in the south of the country. The taxon's range also extends to north Brazil, where it is fairly common in Amapá, northern Roraima, around Manaus and in Pico de Neblina National Park (del Hoyo et al. 1994).
