They use vocalizations to communicate with each other, especially the plains viscachas. The last three units of Paniri are the Viscachas, Laguna and Llareta units. Plains viscachas have distinctive black and white markings on their faces. Viscachas or vizcachas are rodents of two genera ("Lagidium" and "Lagostomus") in the family Chinchillidae.
