Chaccu 🦙✂️ consists of capturing vicuñas with the aim of keeping them in captivity for a few hours to shear them. In this way, its fiber is used without altering the population, behavior, and reproduction capacity of the animals. To achieve this, a group of people walks with ropes in which colored ribbons were tied, herding the vicuñas, and finally, they hold hands, forming a human fence; and in a slow walk, they enclose them in a corral. After obtaining the wool from the animals, they are immediately released. (Wiki)

I had the opportunity to assist one of these, such a magical experience.
