An excerpt -

"Anthropologists have known about the group for some 20 years but released the images now to call attention to fast-encroaching development near the Indians' home in the dense jungles near Peru. Shot in late April and early May, the foundation's photos show about a dozen Indians, mostly naked and painted red, wielding bows and arrows outside six grass-thatched huts.

"We put the photos out because if things continue the way they are going, these people are going to disappear," said Jose Carlos Meirelles, who coordinates government efforts to protect four "uncontacted" tribes for Brazil's National Indian Foundation.

Meirelles told The Associated Press in a phone interview that anthropologists know next to nothing about the group, but suspect it is related to the Tano and Aruak tribes. Anthropologists say almost all of these tribes know about western civilization and have sporadic contact with prospectors, rubber tappers and loggers, but choose to turn their backs on civilization, usually because they have been attacked.

"It's a choice they made to remain isolated or maintain only occasional contacts, but these tribes usually obtain some modern goods through trading with other Indians," said Bernardo Beronde, an anthropologist who works in the region.

Brazilian officials once tried to contact such groups. Now they try to protectively isolate them.

The four tribes monitored by Meirelles include perhaps 500 people who roam over an area of about 1.6 million acres (630,000 hectares)."
