Hunters sometimes called little weasel ermine, and if have mean resemblance of these two animals, of course they are right. Weasel like ermine, has a long, slender, very flexible body, with a small head. Similar color and fur of these two species, except for the black tip of the tail in winter ermine, weasel occurs in only in exceptional cases. But, of course, known to zoologists are significant differences in the structure of the body, and the way of life that distinguish friend another of the smallest members of the family Mustelidae.
Weasel inhabits the entire country with the exception of some islands. Its more diverse habitats than ermine. In the woods it tends to edges, glades and clearings, overgrown garyam and cuttings, shrub swamps, floodplains of rivers and streams.
Basic diet — rodents: voles, hamsters, mice, gerbils. Rarer weasel eats small birds, bird eggs, frogs, fish. Sometimes attack a relatively big game animals — such as a rabbit or a grouse, but these cases are rare.
Usefulness of the affection in forest ecosystems is undeniable. It destroys a large number of forest pests, rodents and causes almost no damage to either the forest or related sectors of the economy. For example, one animal can kill thousands of rodents to 2.5-3 per year.
Forest management activities affect the affection mostly indirectly through changes in cross fodder. Direct damage to the population of this small predator can cause burns and forest processing forest toxicity.
Skin affection had never had a significant difference in the fur trade due to the small size and low strength. In recent years, hunting weasel almost universally banned.
