The taiga vole (Microtus xanthognathus) is a large vole found in northwestern North America, including Alaska and northwestern Canada. The name "taiga vole" comes from its living in the boreal taiga zone.
An adult taiga vole, excluding tail length, usually ranges from in length and usually weighs .
This species is found in northern forests near water or bogs. It makes runways through the surface growth and burrows. It is usually found in colonies. It feeds on grasses, lichens, horsetails and berries. It stores food in its burrows for the winter. Like the singing vole, this animal may give a warning call to alert other members of the colony of danger.
The female vole has litters of 7 to 10 young. The vole population in a given area can vary greatly from year to year.
They are active year-round, usually during dark periods.
Although not commonly encountered, they can be locally abundant.
Distribution and habitat
The taiga vole's habitat stretches from northwestern Canada to Alaska. Fossils have been found as far south as Arkansas, Tennessee and Virginia, suggesting that the taiga voles cover a much smaller range now than in the past. Fossil evidence suggests that they moved northwest after the Wisconsin glaciation event. They also exhibit the use of alarm calls, particularly during the mating seasons to warn potential mates of danger. The taiga vole cannot go more than 24 hours without eating or they can starve to death. They do not have complex metabolisms designed for fasting.
