ThePlains viscacha (Lagostomus maximus), a resident of thePampas ofArgentina, is easily differentiated from other viscachas by black and gray mustache-like facial markings. This species lives colonially inwarrens of 10 to over 100. It is very vocal and emits alarm calls. The plains viscacha can strip grassland used to graze livestock; this has caused ranchers to consider the rodent a pest species.
