Richardson's Water Vole
Arvicola richardsoni

Mice, Voles & Rats
New World Mice & Rats (Cricetidae)

Measurement: Size: 25 cm

Description: Our largest and heaviest vole, the water vole is another common vole of high elevation sedge marshes. Their size is perhaps the best identifier, but they are reddish-brown above and white below. Their nose is blunt, and their eyes seem too small for their body. It feeds on alpine wildflowers including lilies, asters and other flowers. They swim very well, and resemble small muskrats. They tend to use their swimming ability to escape predators, preferring to feed on land. They build tunnels in the riverbanks, and also beneath the snow in winter. They feed on food cached during the summer for their winter diet. Like all mice and voles, they produce several litters per season, with up to five young per litter.
