The water vole (Microtus richardsoni) is the largest North American vole. The Southern Water Vole, Arvicola sapidus, only occurs in freshwater habitats in parts of France, Spain and Portugal, where it is found from sea level to a maximum of about 2,300 metres in the Pyrenees (Le Louarn and Quéré, 2003). The tail is bicolored -- dark above, light below. This is due to heavily pregnant females not venturing far from the burrows and simply popping their heads out and grazing around the edge of the burrow. You can either mix several minced garlic cloves into water to create a spray solution, or drop crushed cloves near your vegetation and vole runways. Another sign of the water vole is a area near the burrow which has been very close cropped (You could practice your putting) on top of a bank. It is active day and night and eats seeds, roots and leaves. Water vole: flatter face, larger eyes at the front, ears hidden in fur, tail is lightly haired (although this is difficult to tell when wet). About The field vole (also known as the short-tailed vole) is very common in grassland, heathland and moorland habitats. The water vole is the second largest 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). [4] Because water voles live in such small isolated patches it is necessary for them to form such a metapopulation structure, in which dispersal can balance out local extinction. It has been found that higher precipitation levels create increased availability of usable habitat for water voles. The male in particular marks its territory with secretions from flank glands. Water voles live near streams, rivers, ditches, ponds, lakes, and other wet places. Some adult females may have up to two litters during one breeding season. Water voles have unusually large hind feet, ranging between 25 and 34 mm in length, which can help distinguish the water vole from other similar rodents, and contribute to its speed in the water. For Old World water voles, see. What can I look for on land? Habitat. It rakes its hind feet over the gland to push the secretion out and then stamps it into the ground. Download this stock image: Water Vole (Cricetidae) Arvicola terrestris. Females give birth and care for her young in these underground nests, lined with leaves and grass. [7], Microtus richardsoni is also known as Richardson's water vole, Richardson vole, Richardson's meadow vole, Richardson meadow mouse, water rat, big-footed mouse, giant water vole, and water vole.[8]. Most often, water voles feed on the subterranean portion of plants, which are available to them year round. - AWBH0C from Alamy's library of millions of high … Search. Males tend to be larger than females. They construct these tunnels and nests just below the roots of the vegetation (about 4–6 cm below ground) during the breeding season (June through late September). Mammalian Species, 223, 1-6. The fur traps air that provides thermal insulation when swimming, and they also possess flaps of skin in the ear that prevent water from entering. The water vole is the second largest arvicoline in its range (after the muskrat). [6] Around the time they reach 40 days of age, they move to their own nests and about 3 weeks later reach sexual maturity. Eau. The distribution of habitats is found to be extremely variable, due to the geographical barriers of large coniferous forests, mountains, and expansive valleys without readily available waterways. Water voles reach 5 – 9 inches in length (120 – 235 millimetres) plus a tail of 55% – 70% of this. Its total length (from nose to tip of its tail) is 8 to 10 1/2 inches. Field Voles are covered in fur which is yellow/brown to greyish in colour. It is often confused with the brown rat, which is slightly larger and has a pointed nose and a shorter, pink, hairless tail. Water Vole Ecology, Conservation and Handling Suitable for all levels of experience, this informative one day event focuses on one of our most iconic river dwelling mammals, the water vole. Scotland’s water voles often appear darker, with many having a black coat. Water voles are most active at night, and they travel between tunnels, nests and waterways by means of surface runways 5–7 cm wide through the vegetation. Vole originated from the Norwegian word vollmus; voll, meaning field, and mus, meaning mouse. The Field Vole has a head and body length of 8 – 13 centimetres, its tail is around one third of its body length. [5] Approximately 26% of young males and females begin to reproduce during the breeding season of their birth,[6] but overwintered adults are responsible for most of the reproduction. See how to tell the difference between a water vole and a brown rat. Although this animal has been historically considered a member of genus Arvicola, molecular evidence demonstrates that it is more closely related to North American Microtus species. Starts in March and goes on until October.

Young leave their mother after 28 days and those born in July may breed that autumn, though most reach sexual maturity after their first winter. In years of that are wetter than usual it has been observed that young water voles become reproductively active sooner, and therefore can have more offspring. It is possible for large, optimal adults to weigh as much as 225 to 386 g (7.9 to 13.6 oz) However, these are peak weights. [10] [4] [5][6], There have been several studies done on the habitat of the vole, given its very specific requirements, to find out if grazing or precipitation levels affect the vole populations so that we can protect them. The Best 20 Gallon Fish Tank Guide – 2020, The Best Aquarium Vacuum Buyers Guide – 2020, The Best Goldfish Food Buyers Guide – 2020, The Best Aquarium Rock Buyers Guide – 2020. The similar brown rat is larger, with grey-brown fur, a pointed nose, large ears that protrude from its … The CL8 Bait Water Vole Wake Bait’s tail can quickly be replaced with the quick screw on tail replacement system, to get you back to catching giants! water \ˈʋaː.tər\ neutre. Adult Water voles weigh from 6 – 12 ounces (160 – 350 grams), juveniles weigh less but must reach around 5 – 6 ounces (140 – 170 grams) to be able to survive their first winter. On average, a female water vole will have up to five litters a year. Studies have shown that water voles have a very high metabolic rate, and therefore don't have to consume as much food as other rodents their size. The long-tailed vole (Microtus longicaudus), in some areas known as the San Bernardino long-tailed vole, is a small vole found in western North America. The bank vole is a small rodent resembling a mouse when young but developing a stouter body, a slightly rounder head with smaller ears and eyes and a shorter, hairy tail. • Water voles excavate extensive burrow systems in the banks of waterways and will have up to five litters per year, ranging from three to seven young. They have short ears and a long tail. It is much bigger than other vole species. Unlike water voles, brown rats are incredibly adaptable, larger and more aggressive - which can actually pose a problem for water voles and other species. Some of the water vole's distinguishing characteristics include blunted snouts and short tails. Retrieved March 21, 2015, from JSTOR. [5] Although, genetic data has been collected that suggests water voles do have the ability to disperse over land to reproduce with other populations, this overland dispersal between colonies tends to be higher with adjacent populations, and less so with increased distance. It has also been found that grazing affects the water vole populations as well. Water voles are territorial during breeding season, marking their territories with steaming piles of green droppings, called latrines. [6], Newborn voles are naked and blind, and weigh about 5 g. They are able to vocalize immediately, and within 3 days start to show fur. 5-6 young, with a minimum gestation period of 22 days. It is also possible that there were influences from Swedish vall, which translates to mean field. When to see January to December. The water vole has chestnut-brown fur, a blunt, rounded nose, small ears, and a furry tail. The head and snout of the Water Vole are flatter and more rounded than those of other rodents, and its ears are generally much smaller. [5] the population of water vole is declining gradually and so today it has become important to preserve them and learn some facts about them. [10] This may be due to the very short breeding season compared to other rodents who breed for 6 months or more. The water vole has chestnut-brown fur, a blunt, rounded nose, small ears, and a furry tail. They form a polygynous social group,[9] in which females tend to stay within their territory, which does not overlap other females, and males travel between burrows to reproduce with several females. Usually in prominent piles along the river bank. Juvenile water voles need to weigh at least 170g to survive winter. The mean number of pups in each litter increased as well. The water vole is occasionally, mistaken for a brown rat, which can be found in a similar habitat. This animal has been historically considered a member of genus Arvicola, but molecular evidence demonstrates that it is more closely related to North American Microtus species.
