The white-throated toucan (Ramphastos tucanus) is a near-passerine bird in the family Ramphastidae found in South America throughout the Amazon Basin including the adjacent Tocantins and Araguaia River drainage. It prefers tropical humid forest, but also occurs in woodland and locally in riverine forest within cerrado. This bird can be found in Bolivia in the Beni Departement, notably in the city of Riberalta and in the close by Aquicuana Reserve.The white-throated toucan was formerly considered to be three separate species. The red-billed toucan and Cuvier's toucan, which differ principally in the bill colour, interbreed freely wherever they meet and therefore now merit only subspecies status. Some authorities consider the Inca toucan to represent a stable hybrid population between the other two subspecies and do not recognize it as a separate subspecies.
