Mountain Viscacha (Lagidium viscacia) lives in rocky Andean slopes across Andes Mountains, South America. Its conservation status is Least Concern.
Fascinating facts about the Mountain Viscacha
- Mountain viscachas can launch themselves more than five metres across rock gaps and drop over fifteen metres down, leaping from barely-sized ledges onto narrow outcrops. Their long hind legs and agile feet with fleshy pads let them cover these distances with ease. This ability lets them move quickly between the small ledges they use as perches, and to escape predators by plunging into underground hideouts when danger approaches.
- They live from 700 up to 5,100 metres above sea level, clinging to sparse vegetation on Andean crags across Argentina, Bolivia, Chile and Peru. The species prefers rocky mountain areas where vegetation is thin, using the crags as shelter and feeding grounds. Their distribution spans the mountainous parts of western Argentina, southern Peru, western and central Bolivia, and northern and central Chile, where they remain close to rocks for safety.
- After a gestation of about 130 days the newborn is fully furred, eyes open and ready to move. The precocial pup can stand and explore its surroundings within hours of birth, while still suckling for about eight weeks. This rapid development allows it to join the colony's daily activities of foraging and sun-bathing soon after birth, increasing its chances of survival in the harsh mountain environment.
- Newborn southern viscachas are born fully furred with eyes open, a condition that lets them move about almost immediately. Although they rely on their mother's milk, they can start nibbling solid vegetation within just a few hours after emerging from the burrow. This early supplement to suckling continues for roughly eight weeks, giving the young a gradual transition to independent foraging while still receiving nourishment from the dam.
- The typical lifespan of a southern viscacha in the wild remains uncertain, yet records from captivity show that individuals can survive for many years. One captive animal lived for 19 years, demonstrating that, under protected conditions, the species can reach nearly two decades of age.

About the Mountain Viscacha
In the rugged, rocky outcrops of the Andes, the mountain viscacha reigns as a master of agility, its long, woolly coat glistening in the high-altitude sunlight as it leaps with effortless ease from boulder to boulder. With a twitch of its whip-like tail, it navigates the treacherous terrain with a nimbleness that belies its sturdy build, its large, dark eyes ever-vigilant for predators lurking in the shadows. As it disappears into the labyrinthine crevices of its mountain stronghold, the viscacha leaves behind a fleeting glimpse of its enigmatic, high-altitude world.
