"Quira, a traditional doctor in the Purace indigenous reserve, leaves a piece of meat on a rock and uses a sprig of sage to drizzle it with a herbal infusion. In his other hand he holds a stick, while his backpack is filled with medicinal plants. Shortly after, a bird spanning three meters from wingtip to wingtip appears through the clouds covering the clearing and swoops down to feast on the offering. The Kokonukos indigenous people consider both the condor and the rock where it perches to be sacred. The volunteers are helping biologists count the condors, one of the largest birds of prey in the world, to help the species survive."
