Vicuna
The
Vicuña (Vicugna vicugna) is a relative of the llama and a
member of the camelid family that lives in the high Andes.
It produces small amounts of extremely fine wool – about a
pound per year. The Incas raised Vicuñas for their wool. It
was against the law for anybody but royalty to wear a
vicuña garments. Both today and under the rule of the Inca,
the vicuña was protected by law. In 1960 there were only
about 6,000 vicuñas in the wild due to uncontrolled
poaching ever since Spanish conquest of South America.
Protection measures were carried out by Peru and Chile,
which raised their numbers up to 125,000. Although the
number is somewhat comforting, these animals are still
classified as vulnerable by the IUCN and endangered by the
USDI.
Description
It
is more delicate and graceful than the guanaco, and smaller.
The 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. Length of head and body is about 5 ft;
shoulder height is around 3 ft; weight under 150 lb.
Distribution
The
distribution of vicuñas in the wild covers South America,
in the central Andes. Specifically, Bolivia, Peru, Chile,
and Argentina.
Habitat
Vicuñas
live in grasslands and plains in the mountainous regions at
an altitude of 4000 to 5500 m. In these areas, only nutrient
poor tough bunch grasses and festuca grows. The sun’s
ultraviolet rays are able to penetrate through 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
that traps layers of warm air close to its body so it can
tolerate the freezing temperatures.
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 that grow in clumps on the ground. It lives 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
180,000 m² 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 months and
becomes independent at about 12 to 18 months. Young males
will form bachelor groups and the young females search for
another group to join. Along with preventing competition, it
also prevents inbreeding which can cause a population
bottleneck in endangered species as observed with cheetahs.
