The Guanaco Llama (Lama Guanicoe) is a camelid animal native to South America that stands between 107 and 122 centimeters (3.5 and 4 feet) at the shoulder and weighs about 90 kg (200 lb). The colour varies very little, ranging from a light brown to dark cinnamon and shading to white underneath. Guanacos have grey faces and small straight ears. They are extremely striking with their large, alert brown eyes, streamlined form, and energetic pace. They are particularly ideal for keeping in large groups in open parklands. The name Guanaco comes from the South American language Quechua word huanaco. The young guanacos are named chulengo(s). The guanaco is native to the arid, mountainous regions of South America. Guanaco are found in the altiplano of Bolivia, Peru, Ecuador, Colombia, Chile and Argentina. In Chile and Argentina they are more numerous in Patagonian regions, in places like the Torres del Paine National Park, and Isla Grande de Tierra del Fuego in fact has an overpopulation of guanacos. Bolivian Indians have been known to raise guanacos to help them regain their population stability. A guanaco's average life span is 20-25 years.
