Voles are small rodents that are relatives of lemmings and hamsters, but with a stouter body; a longer, hairy tail; a slightly rounder head; smaller eyes and ears; and differently formed molars. They are sometimes known as meadow mice or field mice.
The European water vole or northern water vole is a semi-aquatic rodent. It is often informally called the water rat, though it only superficially resembles a true rat. Water voles have rounder noses than rats, deep brown fur, chubby faces and short fuzzy ears; unlike rats their tails, paws and ears are covered with hair.
The eastern meadow vole, sometimes called the field mouse or meadow mouse, is a North American vole found in eastern Canada and the United States. Its range extends farther south along the Atlantic coast.
The northern bog lemming is a small North American lemming. It is one of two species in the genus Synaptomys, the other being the southern bog lemming (Synaptomys cooperi). Very little information is available about this species' life as they are hard to find and study. The northern bog lemming is a small, reddish-brown rodent with a short tail, and distinct markings on their upper teeth. These markings, along with having four pairs of teats, distinguishes this species from the southern bog lemming. The northern bog lemming lives in wet habitats in North America and is omnivorous, eating herbaceous material and invertebrates. They are thought to be extremely sociable animals and sexually mature at around 6 weeks old. Predators include most medium to larger sized carnivorous and omnivorous mammals that eat smaller mammals. The northern bog lemming is listed as a species of "Least Concern" by the IUCN Red List and is considered threatened or of concern in states such as Minnesota and Maine.
The southern bog lemming is a small North American lemming. Its range overlaps with the other species in genus Synaptomys, the northern bog lemming, in southeastern Canada, but extends farther south.
The northern red-backed vole is a small slender vole found in Alaska, northern Canada, Scandinavia and northern Russia.
The long-tailed vole, in some areas known as the San Bernardino long-tailed vole, is a small vole found in western North America. They have short ears and a long tail. Their fur is gray brown with light gray underparts. They are around 18 cm (7.1 in) long with an 8 cm (3.1 in) tail and weigh about 50 g (1.8 oz).
The genus Phenacomys is a group of North American voles. The genus name comes from the Greek for "imposter mouse."
The short-tailed field vole, short-tailed vole, or simply field vole is a grey-brown vole, around 10 cm in length, with a short tail. It is one of the most common mammals in Europe, with a range extending from the Atlantic coast to Lake Baikal. These voles are found in moist grassy habitats, such as woodland, marsh or on river banks. Although they make shallow burrows, they usually build nests above ground. They are an important food source for owls and some other predators and their population size tends to peak and trough cyclically. 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 bank vole is a small vole with red-brown fur and some grey patches, with a tail about half as long as its body. A rodent, it lives in woodland areas and is around 100 millimetres (3.9 in) in length. The bank vole is found in much of Europe and in northwestern Asia. It is native to Great Britain but not to Ireland, where it has been accidentally introduced, and has now colonised much of the south and southwest.
The gray-tailed vole also known as the gray-tailed meadow vole or gray-tailed meadow mouse, is a rodent in the genus Microtus of the family Cricetidae. Voles are small mammals, and this species lies roughly in the middle of their size range. First collected in 1895, it is endemic to the Willamette Valley, Oregon, and Clark County, Washington, in the Pacific Northwest region of North America. Historically, they were found in the prairie areas of the Valley and, though many of these areas have been converted for agricultural purposes, these animals remain common. For reasons that remain unclear, vole population densities in any area may fluctuate widely from season to season and year to year. They are preyed upon by owls, hawks, and carnivorous mammals, and their parasites include fleas and ticks. These voles build burrows and complex tunnel networks, which they sometimes share with other burrowing animals. Relatively little is known about their behavior in the wild, because they are elusive and unlikely to enter traps.
The California vole is a type of vole which lives throughout much of California and part of southwestern Oregon. It is also known as the "California meadow mouse", a misnomer as this species is a vole, not a mouse. It averages 172 mm (6.8 in) in length although this length varies greatly between subspecies.
The European snow vole or snow vole is a species of rodent in the family Cricetidae. It has dense, pale grey fur and a pale-coloured tail and can reach about 14 cm (5.5 in) long, with a tail which is 7 cm (2.8 in) long.
The beach vole or Muskeget vole is a rodent in the family Cricetidae. This close relative of the eastern meadow vole is endemic to the 0.87 km2 Muskeget Island, Massachusetts. Due to its relatively short period of reproductive isolation, there is debate over the beach vole's designation as a subspecies of M. pennsylvanicus.
Maximowicz's vole is a species of rodent in the family Cricetidae. It is found in northeastern China, Mongolia, and eastern Russia.
The montane vole is a species of vole native to the western United States and Canada.
The creeping vole, sometimes known as the Oregon meadow mouse, is a small rodent in the family Cricetidae. Ranging across the Pacific Northwest of North America, it is found in forests, grasslands, woodlands, and chaparral environments. The small-tailed, furry, brownish-gray mammal was first described in the scientific literature in 1839, from a specimen collected near the mouth of the Columbia River. The smallest vole in its range, it weighs around 19 g. At birth, they weigh 1.6 g, are naked, pink, unable to open their eyes, and the ear flaps completely cover the ear openings. Although not always common throughout their range, there are no major concerns for their survival as a species.
Townsend's vole is a species of rodent in the family Cricetidae, the sister species of M. canicaudus. It is found in temperate grasslands of British Columbia in Canada and in the states of Washington and Oregon in the United States.
The Chinese zokor is a species of rodent in the family Spalacidae. It is endemic to China, ranging from Qinghai Province eastwards to Beijing in steppe and alpine grasslands. Henri Milne-Edwards first described it in 1867. Eradication programs in the 1990s in Qinghai Province resulted in a population decline to less than a third of the former population. It is considered common and has been assessed as Least Concern by IUCN.
The Amargosa vole is one of 17 subspecies of the California vole. The most closely related subspecies is M. californicus vallicola.
