Guanacos are wild relatives of llamas and are native to the Andes mountains in South America. They are medium-sized mammals, typically standing about 3 to 4 feet tall at the shoulder and weighing between 200 to 300 pounds. Their thick, soft fur is usually a light brown color, which helps them blend into their natural habitat. These animals are social and often found in groups, which can range from small family units to larger herds. Guanacos primarily graze on grasses and shrubs, and they are well adapted to the harsh conditions of their environment, including high altitudes and extreme temperatures.
