One of South America's few remaining uncontacted indigenous tribes has been spotted and photographed on the border between Brazil and Peru.
The Brazilian government says it took the images to prove the tribe exists and help protect its land.
Survival International says that although this particular group is increasing in number, others in the area are at risk from illegal logging.
Isn't the real risk that they are living in the stone age?
They show tribe members outside thatched huts, surrounded by the dense jungle, pointing bows and arrows up at the camera.
"We did the overflight to show their houses, to show they are there, to show they exist," the group quoted Jose Carlos dos Reis Meirelles Junior, an official in the Brazilian government's Indian affairs department, as saying.
"This is very important because there are some who doubt their existence."
We're treating them like some rare animal instead of human beings.
He described the threats to such tribes and their land as "a monumental crime against the natural world" and "further testimony to the complete irrationality with which we, the 'civilised' ones, treat the world".
I love the quotes around civilized. We're the strange ones getting the most out of natural resources and curing diseases and such. Ah, if we only had the vision to live naked to the elements with our bows and arrows.
