Llama and alpaca ranching is a lucrative business in Chile, so it’s no surprise that ranchers are upset when they find even one calf dead. It’s worse when they can’t determine the cause, and absolutely frightening when the number reaches fifty or more in one concentrated area. That’s what local authorities are being asked to investigate in Colchane, a border area located in northern Chile near Bolivia, where ranchers have lost over 50 young llamas and alpacas to a creature that attacks animals inside their pens, leaves no tracks … and no blood. If that’s not a Chupacabra modus operandi – what is it?
