Parrot DNA shows animal trade networks existed hundreds of years ago
Research reveals pre-Inca societies managed complex trade routes transporting live Amazonian parrots alive across the Andes for elite feather use centuries before the Inca Empire.
- During the Late Intermediate Period , an international research team reports Amazonian parrots were transported alive across the Andes, published in Nature Communications.
- At Pachacamac, archaeologists found colorful parrot feathers in five elite funerary bundles, where plumage served as high-status ritual regalia attached to false heads.
- Genetic and isotopic analyses show DNA sequencing identified four wild-born Amazonian species, stable isotope chemistry revealed coastal diets, and landscape resistance modelling mapped trans-Andean corridors avoiding 5,000-metre peaks.
- Researchers say the discovery challenges Late Intermediate Period isolation and reframes pre-Inca scholarship, providing a deeper baseline for conservation community and modern wildlife-trafficking debates.
- Keeping such birds alive, researchers note, required husbandry knowledge and weeks- or months-long transport, while sequencing fragile feather DNA from the dry Pachacamac tomb enables new trade-tracking methods.
