Pictures: 'World's most endangered tribe'

Rare pictures of what campaigners say is the world's most endangered tribe, whose lands are being cleared by loggers at an alarming rate.
Cutting down trees in this area is illegal but loggers are still cutting and burning the forests where the Awa live. Nearly a third of Awa land has now been taken over.

These pictures are of the Awa tribe in northern Brazil. A campaign group called Survival International says they are the world's most endangered tribe.

Amerintxia is believed to be the oldest Awa, but she still gathers her own food and lives alone in a palm shelter.

Awa women decorate the men with parrot and king vulture feathers for a ritual called the karawara. The ritual involves clapping and singing during which the men enter a trance in an attempt to meet with the spirits of their relatives.

Slings for babies used to be made from palm fibres, but as more Awa contact the wider world materials like cloth are being used. Contacting the outside world is risky because the Awa could catch diseases to which they have never been exposed.

The Awa are hunter-gatherers and travel in family groups of about 30. Family hunts can last for weeks on end but the groups are sometimes attacked by gunmen hired by loggers.

About 360 of the tribe have had some contact with the outside world but there could be around 100 more uncontacted members taking refuge in the Amazon. This man is Takwarentxia who was contacted in 1992 whilst running away from gunmen.

Survival International hopes that by drawing attention to the Awa's plight, pressure will be put on the Brazilian government to enforce the laws and put a stop to illegal logging.
