8 things to know about Channel 4's Lost Tribe of the Amazon

Documentary on indigenous peoples in Brazil and Peru omits crucial information and uses some extremely misleading language

The UK's Channel 4 broadcast a documentary on 23 February titled First Contact: Lost Tribe of the Amazon. It focused on a group of 35 "uncontacted" indigenous people, the "Tsapanawas" or "Sapanahuas", who were filmed in June 2014 turning up at a village in Brazil's Amazon near the border with Peru.

The Tsapanawas' arrival at the village, Simpatia, attracted mass media coverage and Youtube interest. The documentary follows Josi(C) Carlos Meirelles, a "sertanista" who worked for the Brazilian government's National Indian Institute (FUNAI) for 40 years and was in Simpatia when contact was made, returning to the Tsapanawas nine months later. It also focuses on other "uncontacted" people, two groups of "Mashco-Piro", as they are widely-known, in south-east Peru.
