The Guanaco, Lama guanicoe, is a camelid native to the mountainous regions of South America. They are found in the altiplano of Peru, Bolivia and Chile and in the Patagonian regions of Argentina and Chile, where they are most numerous. They are one of the largest wild mammal species found in South America. Guanacos live in herds composed of females, their young, and a dominant male. Bachelor males form separate herds.Their natural predators include cougars, jaguars, and foxes. When they feel threatened, guanacos alert the herd to flee with a high-pitched, bleating call. To escape, they can run up to 56 km (35 miles) per hour, often over steep and rocky terrain. Torres del Paine National Park, Chile, a UNESCO World Biosphere Reserve since 1978.. (Photo by: Jon G.
