The average eastern meadow vole lifespan is less than one month because of high nestling and juvenile mortality. [8] The average time adults are recapturable in a given habitat is about two months, suggesting the average extended lifespan (i.e. how much time adult eastern meadow voles have left) is about two months, not figuring in emigration. [8]
The summer and winter diet of heather voles is predominantly kinnikinnick, a small shrub with evergreen leaves that produces red berries. These herbivores also feed on soapberry leaves and fruits during the summer months. [3] The winter diet of Phenacomys intermedius is bark of bush willow, dwarf birch,sheep laurel, and blueberry. Additionally ...
The average lifespan for smaller species of vole is three to six months, and they rarely live longer than 12 months. Larger species, such as the European water vole, live longer and usually die during their second, or rarely their third, winter. As many as 88% of voles are estimated to die within the first month of life. [14]
Because they feed on roots and tubers, voles do not need to drink water much. [3] Voles cache food, primarily during the winter. [5] Voles spend most of their time underground in their burrow systems and seldom venture into the surface. This makes them safe from hawks and owls. [4] Other predators of voles include snakes, weasels and mountain ...
Field voles breed prolifically, mainly in summer, but often all year round, even under snow. Females produce up to seven litters a year, each averaging from four to six young which are weaned after about fourteen days. The short-tailed field vole is both widespread and common and is listed as being of "Least Concern" by the IUCN.
The montane vole is a more aggressive animal and is known to displace them from their habitat. [4] The more long-tailed voles in a given area, the more aggressive the montane voles become. [4] They feed on green plants, assorted berries, seeds, and fungi. During the winter, diet may consist of the inner bark of shrubs and trees. [7]
Microtus is a genus of voles found in North America, Europe and northern Asia. The genus name refers to the small ears of these animals. They are stout rodents with short ears, legs and tails.
During the winter, northern red-backed voles use layers of thick moss or matted vegetation as thermal cover. [5] [10] During the mid-winter months in a spruce forest of central Alaska, all northern red-backed voles on a control area aggregated in a small area of thick moss cover, despite abundant food resources elsewhere on the trapping grid.
