Jim Williams joins John Fraley to talk about the exciting interactions of mountain lions (called pumas in Chile and Argentina) and their prey in South America, particularly in the large national parks that have been established there. In South America, some of the same conflicts between ranchers and ranch hands (Gauchos), and their livestock are present. Jim traveled to Patagonia to advise the wildlife managers there on how to help humans coexist with lions. In Patagonia, mountain lions prey on a type of camel, an ostrich (Darwin's Rhea), hares, and even Penguins.
