MEMBERS of an indigenous tribe that has long lived in voluntary isolation in Peru’s south-eastern Amazon have attempted to make contact with outsiders for a second time since 2011, leading to a tense stand-off at a river hamlet.
Authorities are unsure what provoked the three-day encounter, but say the Mashco-Piro may be upset by illegal logging in their territory, as well as drug smugglers who pass through. Oil and gas exploration also affects the region.
More than 100 members of the Mashco-Piro clan appeared across the Las Piedras river from the remote community of Monte Salvado in the Tambopata region of Madre de Dios state from 24-26 June, said Klaus Quicque, president of the Fenamad indigenous federation.
They asked for bananas, rope and machetes from the local Yine people, but were dissuaded from crossing the river by Fenamad rangers posted at the settlement, said Mr Quicque, who directed them to a banana patch on their side of the river.
The incident on the Las Piedras is chronicled in video shot by one of the rangers.
“There was a lot of threatening – the intention of crossing. They practically reached mid-river,” he said from Puerto Maldonado, the regional capital.
The video shows Mashco-Piro of all ages and both sexes, including men with lances, bows and arrows. In one image shot during a moment of tension, a man flexes his bow, ready to shoot.
Mr Quicque said the 110-150 people living in Monte Salvado “feared for their lives”. He credited the ranger, Rommel Ponciano, for keeping a cool head.
He said 23 Mashco-Piro appeared on the first day, 110 on the second and 25 on the third. The clan left and hasn’t returned.
“They spoke a variant of Yine,” Mr Quicque said, but Mr Ponciano understood only about two-thirds of the words.
The Mashco-Piro live by their own social code, which includes kidnapping other tribes’ women and children, according to Carlos Soria, a Lima professor and former head of Peru’s park protection agency.
Peruvian law prohibits physical contact with the estimated 15 “uncontacted” tribes in Peru that are estimated to number 12,000- 15,000 people living in jungles east of the Andes. The main reason is their safety: their immune systems are highly vulnerable to germs other humans carry.
Anthropologist Beatriz Huertas, who works with Peru’s agency for indigenous affairs, says the Mashco-Piro are becoming increasingly less isolated. The tribe is believed to number in the hundreds in several clans.
It is not unusual for them to appear during a season when rivers are low, and they tend to be itinerant, she said.
“What’s strange is that they came so close to the population of Monte Salvado,” Ms Huertas said.
Mr Quicque said the Mashco-Piro were victimised by “genocide” in the mid-1980s from the incursion of loggers and subsequently engaged in battles with mahogany-seekers.
Members reappeared in May 2011 on the banks of a different river after more than two decades in voluntary isolation. After those sightings, and after tourists left clothing for the Mashco-Piro, authorities barred all boats from going ashore in the area.
