Description
Most vole species have rootless molar teeth which fold in to a series of triangles. Unlike most rodents, voles' molars, as well as their incisors, grow continuously.
They range in size from three to seven inches in length.
Habitat
Voles live in a variety of environments. The North American meadow vole lives in networks of above-ground "runways" in grassy areas, as well as underground burrows. California's red vole lives in the tree tops.
Range
Sometimes known as field mice in America, approximately 70 species of voles can be found in Europe, Asia, North Africa and North America.
Diet
Diet consists mainly of various green vegetation, such as grasses and clover, but also of tubers, conifer needles, bark, and insects, depending on species.
Predators
Most carnivores in the vole's range, from owls and hawks to coyotes, foxes, weasels, and cats, will eat voles.
Age
Most voles do not live past 12 months.
