Guanacos (Lama guanicoe) are the ancestor of the domesticated Llama, and are members of the camel family. They are found in the Andes in Peru, Chile and Bolivia and at lower altitudes in Patagonian Argentina and Chile. They live in small herds comprised of mostly females and their young, led by a dominant male. Bachelor males may congregate in larger herds of up to 50 Guanacos. Their main predators are pumas and foxes, and when frightened they make a high-pitched bleating call as they run, with the male usually running behind to defend them. Young Guanacos are called chulengos, and stay with their mothers for about a year, after which young males are chased from the herd. They live in steppes, scrubland and mountains, and eat a variety of plants, berries and lichens. Like camels, they can go without water for long periods, and in fact get most of the water they need from the plants they eat. Guanacos have a double coat - long guard hairs cover soft wool on the body. They get blood-sucking lice, ticks and mites, and love dust-bathing to help control these annoying parasites.
