Jivaroan peoples refers to groups of indigenous peoples in the headwaters of the Maranon River, and its tributaries in northern Peru and eastern Ecuador. The principal groups are: Some have also named the following: Moreover, the Shiwiar are a group of Achuar speakers living along the Corrientes River, next to Quechua speakers; many Shiwiar also speak this other, unrelated, language. These names identify speakers of distinct languages of the same language family.. Anthropologists have recognized these languages as distinct peoples, but have called attention to two confounding factors. The first has to do with nomenclature: Jivaroan language speakers typically identify themselves either by their language's word for person (shuar) or by the name of the river on which they live. Consequently, historical sources record either one name for all, or a plethora names of many small Jivaroan tribes, each the name of a different river. The second reason has to do with social organization.
