Guanacos live in the Andean mountains of southern Chile. These wild llama-like "camels" of the Andes spend the summer in this inhospitable territory, giving rise to a season of war. This is the mating season, and the males engage in fierce, no-holds-barred battles for territory and the herd's females. With the arrival of winter, everything changes. The guanacos prepare to migrate to more hospitable territories. The fighting ceases, and they gather in small groups to brave the cold together.
