Annual 'Rodeo of the Andes' as wild vicunas are rounded up

26 August 2010 Last updated at 02:27 BST

The Chaccu is a yearly round-up of wild vicunas, the national animal of Peru.

Small and slender relatives of the llama, vicunas are endangered and prized for their wool.

Because they are wild, a rope more than a mile long is used by Andean villagers to surround the animals and herd them into a corral to be sheared.

And as Dan Collyns finds out, the Chaccu is a sacred ritual which is hundreds of years old.
