field vole nest

M. arvalis maintains aboveground runways, which expand like a railway-system through the entire home range. The cup depression is a good example of how an inner chamber of a tree vole nest would look without a roof. Because of the low availability of food in the winter, drier habitats are unable to sustain populations of much over two hundred animals per hectare. Field voles are not great climbers, preferring to move along the ground through a network of well-used runs … Females are sexually mature at 28 days old, whereas males reach maturity within 40 days after birth. However, they can be active during both day and night. Also known as 'field mice', these rodents are accomplished tunnel diggers, burrowing the ground in search of roots and bulbs, which they feed upon. It is one of the most common mammals in Europe, with a range extending from the Atlantic coast to Lake Baikal. It excavates shallow burrows close to the surface of the ground, under leaf litter and under snow in winter. Meanwhile, young males immediately disperse, being driven away by adult males. Although Field voles dig burrows, they usually build nests above ground at the base of grass stems, sometimes protected by a stone or log. Currently, this species is classified as Least Concern (LC), and its numbers remain stable. The depression was made by a tree vole … The number of voles expands rapidly with the arrival of spring and the better availability of food supplies. However, according to The Mammal society, a recent population estimate put the number of Field voles in Britain at 75,000,000 individuals. Despite their digging habits, these voles nest above the surface on grass stems, which are often protected by a stone or log. Off these are dedicated defecation sites and it often leaves little piles of chopped up grass stalks nearby. Further up the food chain, it forms an extremely important part of the diet of many predators, such as kestrels, weasels and barn owls. The gestation period is about three weeks and up to a dozen young are borne. They feed upon maternal milk for 12 days, leaving the nest by 21 days old, after which female offspring live within or near the home range of their mother. Each vole makes runways among the grass stems, usually centred on a tussock where it nests. The range of the field vole covers a huge territory across northern Europe, stretching from north-west Spain to Russia. [3] The voice is a faint, low squeak and it also emits a range of chattering sounds. Field vole is one of the most common mammals in Britain. Male Red-tail Brings In Vole And Works On Nest Bowl – March 6, 2018 - Duration: 11:10. One of the causes of the large population swings that occur in the field vole is the scramble competition which comes into play when the most desirable food plants are less available in mid summer. The IUCN in its Red List of Threatened Species has therefore listed it as being of "Least Concern". Field voles are induced ovulators. When fighting, they are extremely noisy, emitting loud squeaking sounds and giving out angry chattering noises. [4], The field vole is a herbivore and feeds on grasses, herbs, root tubers, moss and other vegetation and gnaws bark during the winter (it does not hibernate). The Field Vole resembles a small mouse, but with a stouter body and shorter tail. Field voles breed prolifically, mainly in summer, but often all year round, even under snow. The weight is 20 to 50 grams (0.71 to 1.76 oz). After leaving the nest, young female voles remain in or near their mother's home range but young males are forced to disperse by the aggressiveness of the adult males.

Each individual makes paths through the grass stems, starting from a tussock, where nesting site is located. Like the common vole, the field vole is subject to population explosions when conditions are right. Such increased populations are called ‘vole plagues’. The nest is made on or just under the surface of the ground, often in a clump of grass or sedge. It also makes surface runs through tall vegetation, routes along which it can scurry back to safety if danger threatens. The field vole occurs typically in ungrazed grassland or in the early stages of forestry plantations but may also live in woodland, hedgerows, dunes, scree or moorland, wherever grass is available. Field Vole on The IUCN Red List site -, [7] The field vole breeds throughout the year but the breeding season peaks in spring and summer. It is found in a range of habitats including meadows, field borders, plantations, woodland verges, clearings, upland heaths, dunes, marshes, bogs and river banks and tends to prefer wet areas. [5], Field voles are an important part of the diet of barn owls and they are also preyed on by kestrels, other owls, weasels, stoats, foxes and snakes. The pregnancy rate is nearly 100% in late spring but falls during midsummer only to rise again later. The field vole or short-tailed vole (Microtus agrestis) is a grey-brown vole,[2] around 10 cm in length, with a short tail. Life expectancy is about two years but is lower for spring-born individuals than for ones born later in the year. Period of increased activity in this species is dusk. Voles are generally accomplished swimmers and excellent divers. Like the common vole, the field vole is subject to population explosions whe… Voles are seldom seen outside these runways, which enable a faster and safer locomotion and easier orientation.

Field voles are affected by a number of factors throughout their range. These rodents also have special defecation sites, where they leave characteristic little piles of chopped up grass stalks. [8], Male field voles maintain a territory but females just have a home range which may overlap with that of a neighbour. Voles, found near water, often survive tides and flooding due to swimming and climbing to nearby vegetation. Field voles construct their nests both under and above the ground, typically in clumps of grass or sedge. Females produce up to seven litters a year, each averaging from four to six young which are weaned after about fourteen days. For safety reasons, Field voles open paths through high grass, which help them easily run and flee when threatened, returning to their burrows through these routes. Field voles have an important role as key prey for their natural predators (barn owls, kestrels, other owls, weasels, stoats, foxes and snakes). Though very numerous, they have little impact on man except in plague years when they may cause significant damage to crops. They breed from March-April to October-December. Shredded grass leaves are used to make their nests which are about 10cm in diameter and may be built at the base of grass tussocks, in underground burrows or even under sheets of corrugated iron. This animal doesn't tend to enter houses, but can often be seen in backyards. Preferred habitat of these rodents is ungrazed grassland with abundance of vegetation. Mortality in the nest is about 20% but may rise to 50% in the middle of summer when the digestibility of the food supplies fall. Amazon and the Amazon logo are trademarks of, Inc. or its affiliates. The gestation period is about three weeks and up to a dozen young are borne. Little is known about the Field voles’ mating system. These voles are found in moist grassy habitats, such as woodland, marsh or on river banks. Newborn field voles grow rapidly. Voles belong to the family of Cricetidae along with their close relatives, hamsters. The head and body length varies between 8 and 13 centimetres (3.1 and 5.1 in) and the tail between 3 and 4 centimetres (1.2 and 1.6 in). Mediterranean forests, woodlands, and scrub, 2. It occasionally eats invertebrates such as insect larvae. [4], The field vole is more active by day than the common vole. Field voles are found across the UK but are absent from Ireland. [4], The field vole has a palearctic distribution. The field vole (also known as the short-tailed vole) is very common in grassland, heathland and moorland habitats. Gestation period lasts for 3 weeks, giving birth to 4 - 6 young. Underground nests are dug 30 to 40 cm deep into the ground and are used for food storage, offspring raising, and as a place for rest and sleep. Its range extends throughout Western Europe and eastwards to Lake Baikal in Siberia and north west China and northward to Norway, Sweden and Finland.
