The Rikbaktsa, also known as "Orelhas de Pau" (Wooden Ears) or "Canoeiros" (Canoe People), reputed as ferocious warriors in the 1960s, experienced a process of depopulation that resulted in the extermination of 75% of their members. Now recovered, they still have the respect of the regional population in recognition for their persistence in the defense of their rights, territory and way of life.
