Siberian weasel range (green – native, red – introduced) |
The Siberian weasel or kolonok (Mustela sibirica) is a medium-sized weasel native to Asia, where it is widely distributed and inhabits various forest habitats and open areas. It is therefore listed as Least Concern on the IUCN Red List. [1]
The Siberian weasel has a long, stretched out body with relatively short legs. Its head is elongated, narrow and relatively small, and its short ears are broad at the base. Its tail is half the length of its body. Its winter fur is very dense, soft and fluffy, with guard hairs reaching 3–4 cm (1.2–1.6 in) in length. The underfur is dense and loose fitting. Siberian weasels are monotone in colour, being bright reddish-ocherous or straw-red, though orange or peach tones are sometimes noticeable on the skin. These tones are especially bright on the back, while the flanks and underbelly are paler. A dark, coffee-brown mask is present on the face. Their tails are more brightly coloured than the back, and are fluffier than those of other members of the genus. The lips and chin are white or slightly ochreous. The front of the muzzle is darker than the remaining parts of the head. [2] Its skull is in several respects intermediate in form between that of the stoat and the mink; it is longer and larger than that of the stoat, but is somewhat more flattened than the mink's. [3] Adult males are 28–39 cm (11–15 in) long, while females reach 25–30.5 cm (9.8–12.0 in). The tail in males reaches 15.5–21 cm (6.1–8.3 in) in length, while that of females reaches 13.3–16.4 cm (5.2–6.5 in). Males weigh 650–820 g (23–29 oz), while females weigh 360–430 g (13–15 oz). Exceptionally large individuals were sighted in the Baraba steppe. [4]
The Siberian weasel builds its nest inside fallen logs, empty stumps, brushwood piles and exposed tree roots. It also uses and enlarges the dens of other species. The length of its burrows ranges from 0.6–4.2 m (2 ft 0 in – 13 ft 9 in) and 0.2–1.3 m (7.9 in – 4 ft 3.2 in) deep. Adults have a permanent burrow and up to five temporary shelters, which may be separated from each other by several kilometres. They build a nesting chamber in the middle or end of the burrow and line it with bird feathers and rodent hair. [5]
In terms of prey selection, Siberian weasels are midway between small, rodent-eating mustelids such as polecats and the more polyphagous martens. They rarely eat reptiles, invertebrates and plants, preferring instead to prey on rodents of small to moderate size. Water voles are their most frequent prey in their western range, while voles and mice are eaten in their eastern range. Moderate sized rodents targeted by Siberian weasels in the east include Daurian and Alpine pikas, and Siberian zokors. In local areas, chipmunks, muskrats, red squirrels and jerboas are eaten. Fish may be eaten in some areas during certain seasons. In Ussuriland, they scavenge extensively on the kills of wolves and yellow-throated martens during the winter. Elsewhere, small birds are an important food item. Reptiles and amphibians are typically eaten at the periphery of the Siberian weasel's range. Plant foods known to be eaten by Siberian weasels include pine nuts and Actinidia fruits. They typically eat about 100–120 grams (3.5–4.2 oz) of food daily, and cache excess food. [6] In urban areas in China, Siberian weasels prey extensively on rats. They are capable of killing and dragging the largest fowls. [7] Siberian weasels are active hunters and chase prey through snow, logs, water and people's houses. [3] [8]
The rutting period of the Siberian weasel varies depending on location. In western Siberia, it begins in early February to late March. In Primorye, it begins in early March to late April. Six pairs of Siberian weasels in a fur sovkhoz near Moscow were in rut between 25 April and 15 May. They repeatedly mate during 35 minutes. The gestation period lasts 38–41 days. There is one record of a female giving birth after only 28 days. Litters consist of 4–10 kits. They are born blind and are sparsely furred with white hair. They develop light yellow hair after a few days, and open their eyes after a month. They suckle for two months, and become independent by late August. By this time, the young have almost reached adult size, but still have their deciduous teeth and lighter bones. Their fur is darker than that of adults. [9]
As of 2005 [update] , [10] 11 subspecies are recognised.
Subspecies | Trinomial authority | Description | Range | Synonyms |
---|---|---|---|---|
Siberian kolonok Mustela sibirica sibirica | Pallas, 1773 | A small subspecies with light, yellowish-red fur. Skull length in males is 5.8–6.3 cm, while in females it is 4.9–5.6 cm. [11] | All of Siberia eastward to the Zeya River basin, the contiguous parts of Mongolia and possibly the extreme western parts of northeastern China | australis (Satunin, 1911) miles (Barrett-Hamilton, 1904) |
Tibetan kolonok Mustela sibirica canigula | Hodgson, 1842 | Distinguished from other subspecies by having a much greater amount of white fur around the muzzle, neck and almost to the forelimbs. It has an exceptionally thick coat and bushy tail. The body is bright foxy-red, and lacks a black tail-tip. [12] | Tibet | |
Manchurian kolonok Mustela sibirica charbinensis | Lowkashkin, 1935 | Manchuria | ||
Korean kolonok Mustela sibirica coreanus | Domaniewski, 1926 | The Korean Peninsula | peninsulae (Kishida, 1931) | |
Taiwanese kolonok Mustela sibirica davidiana | Milne-Edward's, 1871 | Has a more intense colouration than fontanierii, being almost ochreous orange in fresh winter pelage [13] | Southeastern China north to Hubei and Taiwan | melli (Matschie, 1922) noctis (Barrett-Hamilton, 1904) |

Hodgson's kolonok Mustela sibirica hodgsoni | Gray, 1843 | Distinguished from canigula by the smaller amount of white on the muzzle, the head's darker hue and the white area of the throat being limited to white patches rather than forming a continuous line. It is similar in size to subhemachalana and moupinensis, though its skull is smaller than the latter's. [15] | Kashmir and the western Himalayas from Kam to Garwal | |
Far Eastern kolonok Mustela sibirica manchurica | Brass, 1911 | A somewhat larger subspecies than sibirica, with a lighter red coloured coat. Skull length in males is 6.3–6.7 cm, while in females it is 5.7–6.2 cm. [11] | Priamurye to the west of the Zeya, the Primorye and northeastern China | |
Burmese kolonok Mustela sibirica moupinensis | Milne-Edwards, 1974 | Closely resembles subhemachalana in having a black tail tip, but distinguished by its larger skull and greater incidence of white fur on the muzzle [16] | Sichuan, Gansu, and Yunnan, China and Burma | hamptoni (Thomas, 1921) major (Hilzheimer, 1910) |
Quelpart kolonok Mustela sibirica quelpartis | Thomas, 1908 | Jeju Island, South Korea | ||
Himalayan kolonok Mustela sibirica subhemachalana | Hodgson, 1837 | Smaller than sibirica and has a blackish tail tip. It lacks the typical white patch on the sides of the muzzle, which is blackish, save for narrow white lines on the edge of the upper lip and a white chin. The general colour ranges from bright foxy-red to dark chocolate brown. [17] | The Himalayas from Nepal to Bhutan | horsfieldii (Gray, 1843) humeralis (Blyth, 1842) |
The Siberian weasels ranges from the Himalayas in Pakistan, India, Nepal and Bhutan to northern Myanmar, northern Thailand, Laos, Taiwan, China, and North Korea. In Russia, it occurs in the Kirov Province, Tataria, from the western Urals through Siberia to the Russian Far East. It has been introduced to Honshu, Shikoku and Kyushu islands. [1]
Fossils of the Siberian weasel are known from Denisova Cave. [18]
In Chinese folklore, the Siberian weasel is viewed as a wandering spirit (shen) that can steal and replace people's souls. [19]
Although Siberian weasels are overall useful for limiting rodent populations, they are nonetheless damaging to poultry and muskrat farms. [20] They frequently enter the roosts of domesticated fowl and pigeons, sometimes killing more than they can eat. [7]
Siberian weasels are valuable furbearers, being significantly harvested in Siberia and the Far East. Their fur is used both in its natural state and for imitating the fur of more valuable species. [20] A couple of alternative names for the fur were Tartar sable and fire marten. [21] Siberian weasel fur is also used to make the so-called kolinsky sable-hair brush. In China, their orange fur is largely used to create ink brushes for calligraphers. The name of the brush is thus 狼毫筆, lit. 'wolf hairs brush', as a reduction from 黃鼠狼 + 毫 + 筆, lit. "yellow rat wolf" "hairs" "brush". Their hairs are appreciated because they are harder than goat hair (羊毫). They are hunted by shooting with dogs or through the use of box traps. [20] They are extremely aggressive when caught in traps, emitting piercing shrieks and letting loose a pungent secretion which reportedly takes days to wash away. [7]
The stoat, also known as the Eurasian ermine or ermine, is a species of mustelid native to Eurasia and the northern regions of North America. Because of its wide circumpolar distribution, it is listed as Least Concern on the IUCN Red List. The name ermine is used especially in its pure white winter coat of the stoat or its fur. Ermine fur was used in the 15th century by Catholic monarchs, who sometimes used it as the mozzetta cape. It has long been used on the ceremonial robes of members of the United Kingdom House of Lords. It was also used in capes on images such as the Infant Jesus of Prague.
The wildcat is a species complex comprising two small wild cat species: the European wildcat and the African wildcat. The European wildcat inhabits forests in Europe, Anatolia and the Caucasus, while the African wildcat inhabits semi-arid landscapes and steppes in Africa, the Arabian Peninsula, Central Asia, into western India and western China. The wildcat species differ in fur pattern, tail, and size: the European wildcat has long fur and a bushy tail with a rounded tip; the smaller African wildcat is more faintly striped, has short sandy-gray fur and a tapering tail; the Asiatic wildcat is spotted.
The European polecat, also known as the common polecat, black polecat and forest polecat, is a mustelid species native to Europe, Western Asia and North Africa. It is of a generally dark brown colour, with a pale underbelly and a dark mask across the face. Occasionally, colour mutations including albinos, leucists, isabellinists, xanthochromists, amelanists, and erythrists occur. It has a shorter, more compact body than other Mustela species, a more powerfully built skull and dentition, is less agile, and is well known for having the characteristic ability to secrete a particularly foul-smelling liquid to mark its territory.
The sable is a species of marten, a small omnivorous mammal primarily inhabiting the forest environments of Russia, from the Ural Mountains throughout Siberia, and northern Mongolia. Its habitat also borders eastern Kazakhstan, China, North Korea and Hokkaido, Japan.
The honey badger, also known as the ratel, is a mammal widely distributed in Africa, Southwest Asia, and the Indian subcontinent. Because of its wide range and occurrence in a variety of habitats, it is listed as Least Concern on the IUCN Red List.
The European badger, also known as the Eurasian badger, is a badger species in the family Mustelidae native to Europe and West Asia and parts of Central Asia. It is classified as least concern on the IUCN Red List, as it has a wide range and a large, stable population size which is thought to be increasing in some regions. Several subspecies are recognized, with the nominate subspecies predominating in most of Europe. In Europe, where no other badger species commonly occurs, it is generally just called the "badger".
The long-tailed weasel, also known as the bridled weasel, masked ermine, or big stoat, is a species of weasel found in North, Central, and South America. It is distinct from the short-tailed weasel, also known as a "stoat", a close relation in the genus Mustela that originated in Eurasia and crossed into North America some half million years ago; the two species are visually similar, especially the black tail tip.
The least weasel, little weasel, common weasel, or simply weasel is the smallest member of the genus Mustela, family Mustelidae and order Carnivora. It is native to Eurasia, North America and North Africa, and has been introduced to New Zealand, Malta, Crete, the Azores, and São Tomé. It is classified as least concern by the IUCN, due to its wide distribution and large population throughout the Northern Hemisphere.
The striped hyena is a species of hyena native to North and East Africa, the Middle East, the Caucasus, Central Asia, and the Indian subcontinent. It is the only extant species in the genus Hyaena. It is listed by the IUCN as near-threatened, as the global population is estimated to be under 10,000 mature individuals which continues to experience deliberate and incidental persecution along with a decrease in its prey base such that it may come close to meeting a continuing decline of 10% over the next three generations.
The European mink, also known as the Russian mink and Eurasian mink, is a semiaquatic species of mustelid native to Europe.
The American mink is a semiaquatic species of mustelid native to North America, though human introduction has expanded its range to many parts of Europe, Asia, and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. The American mink was formerly thought to be the only extant member of the genus Neovison following the extinction of the sea mink (N. macrodon), but recent studies, followed by taxonomic authorities, have reclassified it and the sea mink within the genus Neogale, which also contains a few New World weasel species. The American mink is a carnivore that feeds on rodents, fish, crustaceans, frogs, and birds. In its introduced range in Europe it has been classified as an invasive species linked to declines in European mink, Pyrenean desman, and water vole populations. It is the animal most frequently farmed for its fur, exceeding the silver fox, sable, marten, and skunk in economic importance.
The steppe polecat, also known as the white or masked polecat, is a species of mustelid native to Central and Eastern Europe and Central and East Asia.It is listed as Least Concern on the IUCN Red List because of its wide distribution, occurrence in a number of protected areas, and tolerance to some degree of habitat modification. It is generally of a very light yellowish colour, with dark limbs and a dark mask across the face. Compared to its relative, the European polecat, the steppe polecat is larger in size and has a more powerfully built skull.
The beech marten, also known as the stone marten, house marten or white breasted marten, is a species of marten native to much of Europe and Central Asia, though it has established a feral population in North America. It is listed as Least Concern on the IUCN Red List on account of its wide distribution, its large population, and its presence in a number of protected areas. It is superficially similar to the European pine marten, but differs from it by its smaller size and habitat preferences. While the pine marten is a forest specialist, the beech marten is a more generalist and adaptable species, occurring in a number of open and forest habitats.
The yellow-throated marten is a marten species native to the Himalayas, Southeast and East Asia. Its coat is bright yellow-golden, and its head and back are distinctly darker, blending together black, white, golden-yellow and brown. It is the second-largest marten in the Old World, after the Nilgiri marten, with its tail making up more than half its body length.
The tarbagan marmot is a species of rodent in the family Sciuridae. It is found in China, northern and western Mongolia, and Russia. In the Mongolian Altai Mountains, its range overlaps with that of the Gray marmot. The species was classified as endangered by the IUCN in 2008.
The Japanese weasel is a carnivorous mammal belonging to the genus Mustela in the family Mustelidae. The most closely related Mustela species is the Siberian weasel. Its taxonomic species name, itatsi, is based on the Japanese word for weasel, itachi (イタチ). It is native to Japan where it occurs on the islands of Honshū, Kyūshū and Shikoku. It has been introduced to Hokkaidō and the Ryukyu Islands to control rodents and has also been introduced to Sakhalin Island in Russia.
A polecat–mink hybrid, also known as khor'-tumak by furriers and khonorik by fanciers, is a hybrid between a European polecat and a European mink (M. lutreola). Such hybridisation is very rare in the wild, and typically only occurs where European mink are declining. The two species likely began hybridising during the early 20th century, when Northern Europe underwent a warm climatic period which coincided with an expansion of the range of the polecat into the mink's habitat.
The American ermine or American stoat is a species of mustelid native to most of North America. The specific epithet refers to Arctic explorer and naturalist John Richardson.
