Scavenger birds can feed on large to small-sized vertebrates and may contribute in the formation of archaeological sites. To evaluate the modifications and dispersal patterns of bones produced by New World vultures and caracaras from Northwestern Patagonia, samples of adult sheep, young sheep and hare carcasses were offered and subsequently analyzed. New World vultures and caracaras quickly fed on the samples. Taphonomic and bone dispersal patterns suggest two types of accumulations: 1) open air sites with large and medium-sized vertebrates represented by complete, fractured, scratched, notched and punctured elements, and 2) rock shelter or cave sites dominated by small vertebrates represented by broken, corroded, fractured, and digested elements.
