| Vicugna vicugna (Molina, 1782) |
The vicuña (Vicugna vicugna) is one of 2 wild South American camelids, along with the guanaco, which lives in the high alpineous areas of the Andes. It is a relative of the llama and the alpaca. Vicuñas produce small amounts of extremely fine wool. The vicuña's wool is very expensive because the animal can only be shorn every 3 years. When knitted together, the product of the vicuña's fur is very soft and warm. It is understood that the Inca raised vicuñas for their wool, and that it was against the law for any but royalty to wear vicuña garments.
Both today and under the rule of the Inca, vicuñas have been protected by law. In 1960 there were only about 6,000 vicuñas in the wild due to uncontrolled poaching, beginning with the Spanish conquest of South America. Protection measures were carried out by Peru, Chile, and Argentina which raised their numbers up to 125,000. In Andean Bolivia the Ulla Ulla National Reserve was founded in 1977 partly as a sanctuary for the species. Although the recovery is somewhat comforting, these animals are still classified as vulnerable by the IUCN and endangered by the U.S. Department of the Interior.

[edit] Description
The vicuña is considered more delicate and graceful than the guanaco, and smaller. Its long, woolly coat is tawny brown on the back while the hair on the throat and chest is white and quite long. The head is slightly shorter than the guanaco's and the ears are slightly longer. The length of head and body ranges from 1.45 to 1.60 m (about 5 ft); shoulder height from 75 to 85 cm (around 3 ft); weight from 35 to 65 kg (under 150 lb).
in order to prevent poaching there is a round up every year, and all vicunas with fur longer than 2-1/2 centimeters are shorn.
[edit] Distribution
Vicuñas live exclusively in South America, primarily in the central Andes. They are most commonly found in Bolivia, Peru, Chile, and northwest Argentina. But mostly in Peru. Bolivia has great number of wild vicuñas in the Southwestern side of the country.
[edit] Habitat
Vicuñas live in grasslands and plains in the mountainous regions at an altitude of 4,000 to 5,500 meters. In these areas, only nutrient poor tough bunch grasses and festuca grows. The sun's rays are able to penetrate the thin atmosphere producing relatively warm temperatures in the day; however, the temperatures go back to freezing at night. The vicuña's thick but soft coat is a special adaptation which traps layers of warm air close to its body so it can tolerate the freezing temperatures.
[edit] Behavior
The behavior of the vicuña is similar to that of the guanaco. Vicuñas are very shy animals and are easily aroused by intruders. Like the latter, it will frequently lick calcareous stones and rocks, which are rich in salt, and it will also drink salt water. Its diet consists mainly of low grasses which grow in clumps on the ground.
Vicuñas live in family-based groups made up of a male, and 5 to 15 females and their young. Each group has its own territory of about 18km² this can fluctuate depending on the availability of food.
Mating usually occurs in March-April, and after a gestation period of about 11 months the female gives birth to a single young which it nurses for about 10 days; the young becomes independent at about 12 to 18 hours. Young males will form bachelor groups and the young females search for a sorority to join. Along with preventing intraspecial competition, it also prevents inbreeding which can cause a population bottleneck in endangered species as observed with cheetahs.
[edit] Domestication
Until recently it was thought that the vicuña was not domesticated, and that both the llama and the alpaca were both descendants of the guanaco, a very closely related animal. But recent DNA research has shown that the alpaca may well have vicuña parentage. Today the vicuña is mainly wild, but the local people still perform special rituals with these creatures, including a fertilty ritual.
