Sables (Martes zibellina) are long-bodied, short-legged, bushy-tailed weasel relatives (family Mustelidae) found in China, Japan (Hokkaido), Mongolia, North Korea, and Russia. They live in deciduous and coniferous forests (especially mature forests with large trees and a dense canopy), often in mountain regions and near streams. They feed mainly on small mammals (rodents, pikas, hares), but also eat birds, reptiles, amphibians, fish, insects, fruits, honey, nuts, and berries. They are active both day and night. Although mainly terrestrial, they climb trees well. Sables are solitary outside the breeding season.
Sables are common throughout most of their distribution, although they are now considered rare in China (where they were once common). They are hunted for their fur--among the most valuable furs in Europe and Asia--but are also raised on farms to help sustain the fur trade, with over 25,000 harvested annually.
Martes zibellina is found throughout northern Asia, once spanning the area from Scandinavia to northern China (Ognev, 1962). Its current distribution does not extend as far west, but it is still found throughout Siberia into northern China.
Biogeographic Regions: palearctic (Native )
M. zibellina shows sexual dimorphism between males and females. Males have a body length between 380 -560 mm and a tail length between 90-120 mm. The weight of males ranges between 880-1800 grams while females weigh between 700 and 1560 grams. Female body length ranges between 350 and 510 mm and their tail length is 72-115 mm (Walker, 1995). The winter pelage is longer and more luxurious than the summer coat (Ognev, 1962). Fur color ranges from light to dark brown in different sub-species with individual fur color being lighter ventrally and darker on the back and legs (Gizimek, 1990). Individuals also display a light patch of fur on their throat which may be gray, white, or a pale yellow (Ognev, 1962).
Range mass: 700 to 1800 g.
Range length: 350 to 560 mm.
Other Physical Features: endothermic ; bilateral symmetry
Habitat and Ecology
For this species in the Ob region of Russia, Monakhov (2001) found that young animals tended to live near floodplains (lowland forest), while adult animals lived on watersheds (upland forest). "The floodplain group of habitats was represented by haircap moss-sphagnum and dwarf shrub-sphagnum pine and birch-pine forests and dwarf shrub-sphagnum oligotrophic bogs; the watershed habitats included spruce-Siberian stone pine stands with fir, spruce-birch stands with fir and Siberian stone pine, and herbaceous-dwarf shrub-green moss pine forests specked with haircap moss-sphagnum high bogs (Monakhov, 2001)."
This species is found in the dense taiga forests, flatlands, and mountain regions of northern Asia (Grizimek , 1990). M. zibellina are found in the spruce and cedar forests of eastern Siberia and the larch and pine forests of western Siberia. It seems only to avoid extremely barren high mountain tops (Ognev, 1962). The species is mostly terrestrial, hunting and constructing dens on the forest floor (Ognev, 1962).
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: taiga ; forest
M. zibellina are primarily carnivorous feeding on mice, chipmunks, squirrels, bird eggs, small birds, and even fish (Ognev, 1962). Individuals eat berries, cedar nuts, and vegetation when primary food sources are scare (Ognev, 1962). When weather conditions are exteme M. zibellina stores prey inside its den to sustain itself until it can hunt again (Ognev, 1962).
Animal Foods: birds; mammals; fish; eggs
Plant Foods: leaves; seeds, grains, and nuts; fruit
Foraging Behavior: stores or caches food
Primary Diet: carnivore (Eats terrestrial vertebrates, Piscivore , Eats eggs)
M. zibellina is a major predator of small rodents in northern Asia and Siberia.
M. zibellina is well equipped with sharp claws and sharp teeth to defend itself against non-human predators.

Life History and Behavior
Perception Channels: tactile ; chemical
On fur farms individuals have been observed to live up to 18 years, while individuals in the wild probably have a maximum lifespan of 8 years (Tarasov, 1975). Roughly two-thirds of the wild sable population is composed of individuals under two years of age (Tarasov, 1975)
Status: wild: 8 (high) years.
Status: captivity: 18 (high) years.
Status: captivity: 15.0 years.
Lifespan, longevity, and ageing
Males are observed to create ruts, or shallow grooves in the snow about one meter long, accompanied with frequent urination (Tarasov, 1975). Mating takes place between June 15th and August 15th, with the date varying depending on geographic locality (Gizimek, 1990; Ognev, 1962). In areas where individuals are scarce, courting rituals involve running, jumping, and "cat-like rumbling" between males and females, but in areas where male ranges overlap competition for mates can lead to violent battles (Ognev, 1962).
M. zibellina enters heat in the spring. After insemination the blastocyst does not implant into the uteran wall of the female. Implantation occurs about eight months later and embryonic development takes only 25-30 days (Gizimek, 1990). The total pregnancy lasts from 250-300 days with females giving birth to litters ranging in size from 1-7 individuals, but smaller litters of 2-3 individuals are more common. Paternal care has been observed in some individuals as males protect the females' territory and have even been observed to provide food for nursing mothers and their litters (Tarasov, 1975)
Breeding season: June 15th- August 15th
Range number of offspring: 1 to 7.
Average number of offspring: 2-3 .
Range gestation period: 250 to 300 days.
Average weaning age: 7 weeks.
Range age at sexual or reproductive maturity (female): 2 to 3 years.
Range age at sexual or reproductive maturity (male): 2 to 3 years.
Key Reproductive Features: seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; delayed implantation
Average birth mass: 30 g.
Average number of offspring: 3.
Newly born young enter the world helpless, with unopened eyes and a very thin layer of hair (Grizimek, 1990). Newborns weigh between 25 and 35 grams and average 10cm in length (Grizimek, 1990 and Ognev, 1962). M. zibellina open their eyes between 30 and 36 days and leave the nest shortly afterwards (Grizimek, 1990; Walker, 1995). Seven weeks after birth, the young are weaned and are given regurgitated food by their mother (Ognev, 1962). M. zibellina reach sexual maturity in their second year of life (Walker, 1995).

Relevance to Humans and Ecosystems
M. zibellina has been hunted for its fur throughout human history and population numbers had been severely reduced because of extensive hunting early this century (Grizimek, 1990). Hunting is only allowed by licensed persons now and fur farms have been established to allow wild populations to grow. These measures have allowed M. zibellina populations to grow and reestablish the wider range that they once occupied in the taiga (Grizimek, 1990)
The sable (Martes zibellina) is a species of marten which inhabits forest environments, primarily in Russia from the Ural Mountains throughout Siberia, eastern Kazakhstan, northern Mongolia, China, North and South Korea and Hokkaidō in Japan. Its range in the wild originally extended through European Russia to Poland and Scandinavia. It has historically been hunted for its highly valued fur, which remains a luxury good to this day. While hunting of wild animals is still common in Russia, most fur in the market is now commercially farmed.
The name sable appears to be of Slavic origin and to have entered most Western European languages via the early medieval fur trade. Thus the Russian соболь (sobol) and Polish soból became the German Zobel, Dutch Sabel; the French zibeline, Spanish cibelina, cebellina, Finnish soopeli, Portuguese zibelina and Mediaeval Latin zibellina derive from the Italian form (zibellino). The English and Medieval Latin word sabellum comes from the Old French sable or saible.
Males measure 38–56 centimetres (15–22 in) in body length, with a tail measuring 9–12 centimetres (3.5–4.7 in), and weighing 880–1,800 grams (1.94–3.97 lb). Females have a body length of 35–51 centimetres (14–20 in), with a tail length of 7.2–11.5 centimetres (2.8–4.5 in). The winter pelage is longer and more luxurious than the summer coat. Different subspecies display geographic variation in fur colour: fur color ranges from light to dark brown, with individual fur color being lighter ventrally and darker on the back and legs. Japanese sables (known locally as クロテン or kuroten) in particular are marked with black on their legs and feet. Individuals also display a light patch of fur on their throat which may be gray, white, or a pale yellow. The fur is softer and silkier than that of American martens. Sables greatly resemble pine martens in size and appearance, but have more elongated heads, longer ears and proportionately shorter tails. Their skulls are similar to those of pine martens, but are larger and more robust with more arched zygomatic arches.
Sables inhabit dense forests dominated by spruce, pine, larch, cedar, and birch in both lowland and mountainous terrain. They defend home territories that may be anything from 4 to 30 square kilometres (1.5 to 11.6 sq mi) in size, depending on the local terrain and availability of food. However, when resources are scarce they may move considerable distances in search of food, with travel rates of 6 to 12 kilometres (3.7 to 7.5 mi) per day having been recorded.
Sables live in burrows near riverbanks and in the thickest parts of woods. These burrows are commonly made more secure by being dug among tree roots. They are good climbers of cliffs and trees. They are primarily crepuscular, hunting during the hours of twilight, but become more active in the day during the mating season. Their dens are well hidden, and lined by grass and shed fur, but may be temporary, especially during the winter, when the animal travels more widely in search of prey.
Sables are omnivores, and their diet varies seasonally. In the summer, they eat large numbers of hares and other small mammals. In winter, when they are confined in their retreats by frost and snow, they feed on wild berries, rodents, hares, and even small musk deer. They also hunt ermine, small weasels and birds. Sometimes, sables follow the tracks of wolves and bears and feed on the remains of their kills. They eat molluscs such as slugs, which they rub on the ground in order to remove the mucus. Sables also occasionally eat fish, which they catch with their front paws.
They hunt primarily by sound and scent, and they have an acute sense of hearing. Sables mark their territory with scent produced in glands on the abdomen. Predators on the sable include a number of larger carnivores, such as wolves, foxes, wolverines, tigers, lynxes, eagles and large owls.
Mating generally occurs between June and August 15, though the date varies geographically. When courting, sables run, jump and "rumble" like cats. Males dig metre long shallow grooves in the snow, frequently accompanied with urination. Males fight violently with each other for females. Females enter estrus in spring. Mating can last as long as eight hours. After insemination, the blastocyst does not implant into the uterine wall of the female. Instead, implantation occurs eight months later; although gestation lasts 245 to 298 days, embryonic development requires only 25–30 days. Sables birth in tree hollows, where they build nests composed of moss, leaves, and dried grass. Litters number one to seven young, although litters of two or three are most common. Males assist females by defending their territories and providing food.
Sables are born with eyes closed and skin covered in a very thin layer of hair. Newborn cubs weigh between 25 and 35 grams (0.88 and 1.23 oz) and average 10 to 12 centimetres (3.9 to 4.7 in) in length. They open their eyes after 30 to 36 days, and leave the nest shortly afterwards. At seven weeks old, the young are weaned and given regurgitated food. They reach sexual maturity at the age of two years. They have been reported to live for up to twenty two years on fur farms, and up to eighteen years in the wild.
Sables can interbreed with pine martens. This has been observed in the wild, where the two species overlap in the Ural Mountains, and is sometimes deliberately encouraged on fur farms. The resulting hybrid, referred to as a kidus, is slightly smaller than a pure sable, with coarser fur, but otherwise similar markings, and a long bushy tail. Kiduses are typically sterile, although there has been one recorded instance of a female kidus successfully breeding with a male pine marten.
In Russia, the sable's distribution is largely the result of mass reintroductions involving 19,000 animals from 1940 to 1965. Their range extends northward to the limit of trees, and extends southward to 55–60° latitude in western Siberia, and 42° in the mountainous areas of eastern Asia. Their western distribution encompasses the Ural mountains, where they are sympatric with European pine martens. They are also found on Sakhalin.
In Mongolia, sables occur in the Altai Mountains and in the surrounding forests of Lake Hovsgol, the latter being contiguous with the Trans-Baikal boreal forest region from which the most valuable sable pelts come. In China, sables occur in a limited area of the Xinjiang Uygur Autonomous Region. In northeastern China, sables are now limited to the Daxinganling Mountains. In eastern Heilongjiang, the persistence of sables is suspected in the Xiaoxinganling Mountains. Sables also occur in Hokkaido and on the Korean peninsula.
Because of the variable appearance of the sable in different geographic localities, there has been some debate over the exact number of subspecies that can be clearly identified. Mammal Species of the World recognises seventeen different subspecies, but other recent scholarly sources have identified anything from seven to thirty.
History of fur use and status
Sable fur has been a highly valued item in the fur trade since the early Middle Ages, and is generally considered to have the most beautiful and richly tinted pelt among martens. Sable fur is unique because it retains its smoothness in every direction it is stroked. The fur of other animals feels rough stroked opposite the grain. A wealthy 17th-century Russian diplomat once described the sable as "A beast full marvelous and prolific ... a beast that the Ancient Greeks and Romans called the Golden Fleece." Russian sables would typically be skinned over the mouth with no incision being made on the body. The feet would be retained, so as to keep as much fur as possible. Byzantine priests would wear sable for their rituals.
In England, sable fur was held with great estimation. Henry I was presented with a wreath of black sable by the Bishop of Lincoln, for no less than £100, a considerable sum at the time. Sable fur was a favourite of Henry VIII, who once received five sets of sable fur worth £400 from Emperor Charles V. Henry later decreed that sable fur was to be worn only by nobles exceeding the rank of viscount. The Russian conquest of Siberia was largely spurred by the availability of sables there. Ivan Grozny once demanded an annual tribute of 30,000 sable pelts from the newly conquered Kazan Tatars, though they never sent more than a thousand, as Russia at the time was unable to enforce the tribute due to wars with Sweden and Poland. The best skins were obtained in Irkutsk, Kamchatka, and Lapland.
According to the Secret History of the Mongols, when Genghis Khan married his first wife, Börte Ujin, his mother Hoelun received a coat of sable furs from the girl's parents. This was reportedly a very noble gift, serving not only an aesthetic need but also a practical one.
According to Atkinson's Travels in Asiatic Russia, Barguzin, on Lake Baikal, was famed for its sables. The fur of this population is a deep jet black with white tipped hair. Eighty to ninety dollars were sometimes demanded by hunters for a single skin. Sable fur would continue to be the most favoured fur in Russia, until the discovery of sea otters in the Kamchatka peninsula, whose fur was considered even more valuable. Sable furs were coveted by the nobility of the Russian Empire, with very few skins ever being found outside the country during that period. Some however would be privately obtained by Jewish traders and brought annually to the Leipzig fair. Sometimes, sable hunting was a job given to convicts exiled to Siberia.
Imperial Russian fur companies produced 25,000 skins annually, with nearly nine tenths of the produce being exported to France and Germany. The civic robes of the Lord Mayor and Corporation of London, which were worn on State occasions, were trimmed with sable. As with minks and martens, sables were commonly caught in steel traps. Intensified hunting in Russia in the 19th and early 20th century caused a severe enough decline in numbers that a five-year ban on hunting was instituted in 1935, followed by a winter-limited licensed hunt. These restrictions together with the development of sable farms have allowed the species to recolonize much of its former range and attain healthy numbers.
The Soviet Union allowed Old Believer communities to continue their traditional way of life on the condition that they hand over all sable skins they produced. The dissolution of the Soviet Union led to an increase of hunting and poaching in the 1990s, in part because wild caught Russian furs are considered the most luxurious and demand the highest prices on the international market. Currently, the species has no special conservation status according to the IUCN, though the isolated Japanese subspecies M. zibellina brachyurus is listed as "data-deficient".
Because of its great expense, sable fur is typically integrated into various clothes fashions: to decorate collars, sleeves, hems and hats (see, for example the shtreimel). The so-called Kolinsky sable-hair brushes used for watercolour or oil painting are not manufactured from sable hair, but from that of the Siberian weasel.
