Long-tailed weasels are 11 to 17 inches long and weigh between 3 and 10 ounces. Description. Conservation status Least weasels are seldom seen and thus considered relatively rare. The least weasel’s fur will tend to fluoresce under UV light. Population number. The Least Weasel lives in the Taiga biome. The least weasel's habitat consists of living in stone walls, hedges, farmland, and the woods. Least weasels are dark brown with light underparts in the summer. Least weasels can counteract predation events by using their camouflaged pelage to blend in with substrate and aggressive behavior, such as vocalizations and biting, and by hiding in shelters. The least weasel weighs 1 ounce and is only 4 to 10 inches in length. The Least Weasel, which is the smallest carnivore in North America, can be found in the middle and eastern areas of the state. The least weasel is the world’s smallest carnivorous animal. Most of the species are commonly called weasel. They avoid open spaces. The Least Weasel makes long term adaptations as well as short term changes. Common Name: Least Weasel Scientific Name: Mustela nivalis Habitat: Varied habitat including old fields, open woodlands, and brushy areas. A least weasel. Some weasel species have fur that changes color; in the winter, their fur will turn white to blend in with the snow. Weasels and people. Weasel - Mustela nivalis Taxon: Carnivora Weasel Red List Classification: GB: Least Concern England:Least Concern Scotland: Least Concern Wales: Least Concern Global: Least Concern General fact sheet (click to download) Field sign fact sheet (click to download) Habitat: Urban & gardens, rivers and wetland, coniferous woodland, deciduous woodland, grassland, mixed woodland, arable land. The Division of Wildlife’s mission is to conserve and improve fish and wildlife resources and their habitats for sustainable use and appreciation by all. Abundance of small mammals is important in determining the local distribution of Least Weasels. The least weasels are the smallest of all members of the weasel family. They are very secretive and wary, but also very aggressive. Their skull is long and flat, with short, round ears, long whiskers and large, dark eyes. The diet is affected by habitat. Stepping inside a wood is like stepping outside of time. In favorable habitat, maximum densities of the least weasel may reach 65 per square mile (169/km2); the short-tailed weasel, 21 per square mile (54/km2); and the long-tailed weasel, 16 to 18 per square mile (40 to 47/km2). The short-tailed weasel is the most common weasel. Their tails are short, ears are rounded and short, whiskers are prominent, and eyes are black. The chirp is a threat cry. Diet European Weasel (long-tailed weasel) and the Least Weasel (Mustela nivalis) are the most common species which is found and spread across the northern hemisphere. Habitat and conservation: The least weasel lives in low, sparse ground cover such as pastures, stubble fields, and marshy areas, sometimes even mouse-infested barns. It can be found in fields, open woodland, bushy or rocky areas, parks and gardens, and at altitudes of up to about 3,000 metres (9,800 ft). Both weasels have long, slender bodies and wide heads, small rounded ears, and short legs. A group of weasels may be referred to as a “boogle”, “confusion”, “gang” or “pack”. They characteristically turn entirely white in the winter but retain a few black, brown, and white hairs on their tail during all seasons. Both have long, slender bodies, short legs, and a broad, slightly flattened head that's barely larger around than the neck. The weasel is a small, long-bodied, carnivorous mammal of the family Mustelidae. Least weasels may also be preyed upon by other larger weasel species, such as ermines and long-tailed weasels. Since weasels are considered the best mousers in the boreal forest, Yukon First Nation trappers like to have them around their cabins to keep the rodents down. Below are some plants and their adaptations. They are solitary and are active both during the day and at night. Three species of weasels are found in Canada: the short-tailed weasel, also known as the ermine or stoat (Mustela erminea), the long-tailed weasel (Mustela frenata), and the least weasel (Mustela nivalis).The least weasel is the smallest species in the order carnivora. The least weasel is the smallest living carnivore. When rodents are scarce they will feed on bird eggs, nestlings, and small reptiles. The stoat is larger than the least weasel and has a proportionally longer tail. Interesting Facts: This is the smallest carnivore in Pennsylvania with a total length of only eight inches and a weight of only two ounces! The least weasel’s tail is shorter than that of the stoat, and lacks the black coloration. The long-tailed weasel is two to three times larger than the least weasel. The least weasel is the smallest true carnivore on Earth, but also one of the most fierce. These vicious predators are closely related to the stoats. Note the short tail. The variations in fur color is dictated by the changing seasons. Pine tree adaptations:- The taiga soil doesn't contain many nutrients, and the Sun usually remains low in the sky.- These two factors limit the amount of energy available to the tree.By keeping their leaves, the evergreens are able to use that limited energy for structural growth rather than producing leaves. They feed mostly on small rodents. This is often referred to as the “ermine” phase. The least weasel is the smallest of all weasels, averaging 157-190 mm (6.2-7.5 in.) Diet: The least weasel is primarily a carnivore. Least weasels also hiss when afraid or threatened and trill in friendly encounters with other least weasels. They make their homes in mole runs or pocket gopher burrows they have taken over. The least weasel occupies a similar type of habitat as the stoat but it less often frequents wet places. Nest in shallow burrow about 5 inches underground (Jones et al. Weasel kits eat voraciously, grow rapidly, and are able to kill small mice within seven weeks. They are fully grown in 12 to 15 weeks, after which families break up and the young set up territories of their own. Kits grow rapidly, can achieve adult size and self-sufficiency at 4-5 weeks, and reach sexually maturity by 3-8 months (Chapman and Feldhamer, 1982). It may be present in fields, open woodland, bushy or rocky areas, parks and gardens, and at altitudes of as much as about 3,000 meters (9,800 ft). Least weasels will cache excess food for later use. This type of weasel favors habitats that include moors, marshes, grassland, woodland, mountains, dunes, and urban areas. They mostly inhabit areas with good cover and an abundant supply of prey. They usually go where the mice are. Description: A small mammal with a long, slender body, short legs, flattened head, and a long neck. The most common food is the meadow vole but they also take other voles, mice, shrews, insects and small birds. 1983). They make nests in crevices, tree roots or abandoned burrows and they have a range of 1 - 25 hectares. The least weasel is the smallest carnivore in the world. in total length and weighing 40-56 g (1.4-2.0 oz.)

Because its tiny size and lack of a black-tipped tail, there is little commercial value in Least Weasel fur. The IUCN Red List and other sources do not provide the Japanese weasel total population size. Other factors which may pose a threat to this species include habitat and prey loss, poisoning, and predation. In Pennsylvania, the ermine is found mostly in the northern and eastern parts, the long-tailed is common throughout the state, and the least is found in The least weasel was listed as a special concern species in Minnesota in 1996.

The long-tailed weasel is two to three times larger than the least weasel. The weasel has a russet-brown back, and a creamy white throat and belly. Foods. and Least Weasel will opportunistically switch among prey species based on availability and type of hunting habitat available 2. They can enter holes in the ground less than an inch in diameter. They do not prefer a particular habitat, over any other and can be found anywhere. Diet: Carnivorous, especially mice, shrews, insects, ground-nesting birds, and carrion. It is also called the little weasel, common weasel. The stoat shares much of its range with the closely-related least weasel.
