Adventurers have released rare drone footage of members of a tribe walking through their jungle camp in the state of Amazonas, Brazil.

The video was captured between July 16 and August 1, 2017, but researchers at Brazilian government indigenous agency Funai (Fundacao Nacional do Índio) waited until August 22, 2018, to release it.

The clip shows members of the tribe in Vale do Javari, in the southwest of Amazonas, on the border between Brazil and Peru. Funai has discovered 11 separate groups living in the area, a spokesman said in an accompanying press release.

Vitor Gois, a Funai investigator who coordinated the field work, said the new video footage would be useful in the agency’s ongoing protection of Brazil’s indigenous people.

“Surveillance and monitoring must be intensified in the region to curb the actions of violators and ensure the full possession of the territory by the indigenous people,” he said.

Investigators also released images of tools and objects used by the tribe. Credit: Fundacao Nacional do Indio via Storyful
