New analysis of ancient parrot DNA has revealed that vibrant Amazonian parrots were transported alive across the Andes to coastal Peru centuries before the Inca Empire, highlighting a sophisticated pre-Inca, long-distance trade network spanning rainforest, highlands and deserts. The international team of researchers, including scientists from The Australian National University (ANU), analyzed parrot feathers that were discovered at Pachacamac, Peru—one of the preeminent religious centers of the Andean civilization—far outside the birds' native rainforest range. The research is published in Nature Communications.
