Every year, Peru carries out the chaccu, when vicuñas (wild relatives of the llama) are sheared for their wool. It happens in the final week of June at Pampa Galeras-Bárbara d'Achille Natural Reserve, in Ayacucho. This traditional hunt for the vicuna dates back to pre-Hispanic times.
With the cry of “¡Chacutay jayaycusa!” (Let's start chaccu!), followed by the answer “Chaccu!” this annual event starts.
