New World Mice & Rats (Cricetidae)

Description: The meadow vole is common throughout the Rockies, but at lower elevations than the western red-backed vole. It prefers moist montane meadows with a profusion of sedges and marsh grasses. They are uniform brown above, and white or gray beneath. Their ears are short and often held almost flat against the body. They follow regular pathways through the heavy grasses in search of food, or food caches. Active year-round, they create caches of food to get them through the long winter. They create winter pathways beneath the protection of heavy layers of snow. They are extremely popular, and active at all times of the day. Their population fluctuates dramatically over time, with peak populations in the area of 1000 per ha. They are also very prolific with three or four litters annually of three to five per litter.
