Habitat and Ecology
This species is typically found in moist habitats with scattered rocks and close to dense riparian habitats (including boggy areas). In Peru the species lives in thick grass or brushy grasslands and disturbed gallery forest in which it makes distinct runways. It is present in both primary and disturbed habitats. In Argentina it has been reported to live in burrows with multiple entrances. In captivity the gestation period is 63.3 days, litters average 1.9 (range 1-4), and the average age of first reproduction is two months (Weir, 1974; Eisenberg and Redford, 1999).

Montane Guinea Pig

Learn more about this article

The Montane Guinea Pig, Cavia tschudii, is a guinea pig species from South America. It is found in Peru.

Peruvian wild guinea pigs were first described by E. T. Bennett in 1835, who termed them Cavia cutleri. Johann Jakob von Tschudi, in an 1845 publication, used the term Cavia cutleri to refer to what are now considered two separate entities - the first, Bennett's Cavia cutleri, which was later (by Oldfield Thomas in 1917) identified as probably a differently-pigmented version of Cavia porcellus, and the second, a wild Peruvian pig that was clearly different from the animal Bennett described.[3] In 1867[2], Leopold Fitzinger renamed the latter guinea pig Cavia tschudii.[3]
