We're back on the Amazon on the final leg of the journey. Yesterday we left the Kayapo village of Krinu where we've been staying for the last week and it was an amazing feeling to know that from here on in we're all on the way home...it was quite emotional bumping along the dusty airstrip waving to the Kayapo who came out en masse to say goodbye.
4.30 am. Pitch dark. The rats were busy scampering around the floor of the crew's hut. A dog howled at the moon. And then scratched. I wondered what woke me, as it started again. Like a drunk on a moonlit backstreet the wail began. A Kayopo elder was calling the tribe to dance. The huts - arranged in a large square of 20 or so - seemed to sleep on regardless. I really wished I could have. The call was incessant. What could be so important? Even the rats took no notice.
Ceremony and ritual is an incredibly important part of the Kayapo way of life. They believe that by dancing, they are able to go back to a time of mythical origins, and in so doing, recreate the energy and drive they need in order for life to continue. Most of the rituals and ceremonies we took part in seemed similar to each other - to the untrained eye, it was a great deal of chanting in a large circle, men, women and children, sometimes around a fire.
We're on the final main shoot of the series, staying with the Kayapo Indigenous People on their reserve in the south of Para state. They are proud warriors yet at the same time very gentle hosts, and have given us a very warm and traditional welcome.
The Kayapo are known as a warrior Indian tribe and now, more than ever, they're having to fight to preserve their land as cattle ranchers encroach further and further into Indian territory to make way for pasture. While we were there, they took us up the hill close to their reservation. From here, they showed us just how much land close to their reservation had been turned to pasture.
We've arrived at the Kayapo village of Krinu. It's my first time staying with an Indian tribe. We got here at dusk, a magical time for the light, catching the straw and wooden huts on the outskirts of the vast dusty circle they're arranged around. It's an impressive space.
