Isotopes of feather art: location, husbandry, production and antiquity

N) combined with radiocarbon measurements. We document the monotonously fed rearing of thousands of captive macaws in the Amazon region and the acquisition of camelid fibres from the high Andes to produce ninety-six large feather panels. Multiple radiocarbon dates from both feathers and fibres confirm the Wari (600-100 AD) origin of the panels and suggest a short and intensive production schedule. Stable isotopes document the collection of materials that took the artisans over hundreds of kilometres from the Amazon to near the Pacific coast.
