Travelling some 1100 kilometres by boat and 70k on foot through the Brasilian Amazon , FUNAI Official and expedition leader Bruno Pereira travelled into the protected reserve of Vale do Javari to lead a team of Indigenous Marubo and Korubo people in search Brasil's uncontacted people. The reserve was established to protect the land from exploitation and create a lasting homeland for its people. It is one of the largest indigenous territories in Brasil and is home to some 3000 isolated indigenous peoples and an estimated 2000 uncontacted people. There has been a history of mistrust, fear, and aggression between the uncontacted and indigenous tribes, but also one between the tribes themselves. A raid on a Marubo Village one month prior by two uncontacted men had created a fear of their movements and intentions. FUNAI's aim was not to make forced contact but to to document their movements, possible shelters and to create a lasting working dialogue with the indigenous peoples within the reserve. For the first time Bruno Pereira created an expedition team of mixed tribal origins. The Korubo people are known locally as 'The Headbangers' after their fearsome fighting methodology. They have been largely credited with maintaining the reserves untouched wilderness condition by defending it from the actions of the illegal logging industry.
Entry to the reserve is restricted, controlled and guarded at the head of the Rio Itu by the FUNAI base.
