The Siona of Ecuador

The Siona of Ecuador, numbering approximately 375 people, are No Longer Unreached. They are an Amazonian people of Ecuador's Cuyabeno reserve who merged with the closely related Secoya into a single Siona-Secoya identity by the 1970s before choosing to maintain separate identities, their population later split by the 1941 Peru-Ecuador border war. They mostly adhere to Ethnoreligion and Siona is their primary language.
