Ramirez (2017) found only 2 remaining speakers of Warázu, an elderly couple consisting of Känä́tsɨ [kənə́tsɨ] (José Frei Leite) and Híwa (Ernestina Moreno). They were born in Riozinho (Urukuríti) in Rondônia, Brazil, and moved back and forth between Brazil and Bolivia until finally settling in Pimenteiras do Oeste, Rondônia. Traditionally, the Warázu people had lived in the following 7 villages along the banks of the Guaporé River. However, the Warázu language is no longer spoken in these localities.
