How many weasels

These predators are not much bigger than the mice and voles they eat, typically measuring just 20—27cm long. Even the largest male weasel is unlikely to weigh more than g, while a small female may be just 50g. Not to be confused with: the stoat, which is larger and has a longer tail that ends in a bushy black tip.

Weasel tails are always wholly brown. Did you see a stoat on your last woodland walk? Or perhaps it was a weasel? Our guide will help you to tell these pint-sized predators apart. We also take a look at some of the other related species found here in the UK. It can also take larger prey, such as young rabbits, and will readily hunt birds and their eggs too. The weasel has an extremely high metabolism and needs to eat roughly a third of its own body weight daily.

Weasels are solitary and only come together to mate. A litter of around four to six young, known as kits, will be born between April and August. Weasels are found throughout Britain, but are absent from Ireland. They have even been known to take over termite hills. Weasels' diets usually consist of rats, mice, voles and rabbits. Frogs, birds and bird eggs are also on the menu, from time to time. Their small, thin bodies allow them to squeeze into tight spots to reach small prey.

Females typically have one or two litters per year. They give birth to litters of up to 15 offspring, called kits, according to ADW. Gestation lasts about a month. However, the number of kits, the length of the gestation period, weaning age and sexual maturity varies with the species. For example, long-tailed weasels mate in mid-summer, but implantation is delayed and the egg does not begin to develop until March, making the gestation period about days, according to ADW.

There are a few exceptions. Male and Female stoats and weasels are referred to as a dog and a bitch respectively. The young are called kittens or kits. Collective nouns for a group of weasels include boogle, gang, pack and confusion. Weasels vary in length, but generally, male weasels measure around 20 — 22 centimetres long and have a tail length of 6.

The average weasel weighs about grams 7 ounces , however, males usually weigh up to grams and females up to 59 grams. Weasels bodies and necks are shaped cylindrically, they are long and slender and they have short legs.

Their long slender bodies enable them to follow their prey into burrows. The weasel is smaller than the stoat and lacks the small white patches under their chin and throat. In many weasel species, populations living at high latitudes moult to a white coat with black fur at the tip of the tail in winter.

Weasels have sharp eyesight and excellent hearing. Weasels have a wide range of habitats from grasslands, sand dunes, lowland forests to upland moors and even towns, anywhere where there is suitable food. Their nests are made of grass and leaves, usually in holes in a wall, or tree stumps.

Weasels feed on small mammals and in former times were considered vermin since some species took poultry from farms, or rabbits from commercial warrens. Least weasel, Mustela nivalis left ; Shorttailed weasel, M. Weasels are active in both winter and summer; they do not hibernate. Weasels are commonly thought to be nocturnal but evidence indicates they are more diurnal in summer than in winter. Home range sizes vary with habitat, population density, season, sex, food availability, and species Svendsen The least weasel has the smallest home range.

Males use 17 to 37 acres 7 to 15 ha , females 3 to 10 acres 1 to 4 ha. The short-tailed weasel is larger than the least weasel and has a larger home range. Male short-tailed weasels use an average of 84 acres 34 ha , and females 18 acres 7 ha , according to snow tracking.

The long-tailed weasel has a home range of 30 to 40 acres 12 to 16 ha , and males have larger home ranges in summer than do females.

The weasels appear to prefer hunting certain coverts with noticeable regularity but rarely cruise the same area on two consecutive nights. Weasel population densities vary with season, food availability, and species. Population densities fluctuate considerably with year-to-year changes in small mammal abundance, and densities differ greatly among habitats.

Weasels, like all mustelids, produce a pungent odor. When irritated, they discharge the odor, which can be detected at some distance Jackson Long-tailed weasels mate in late summer, mostly from July through August. Females are induced ovulators and will remain in heat for several weeks if they are not bred.
