The stoat (Mustela erminea), also known as the short-tailed weasel, is a species of Mustelidae native to Eurasia and North America, distinguished from the least weasel by its larger size and longer tail with a prominent black tip. The name ermine is often, but not always, used for the animal in its pure white winter coat, or the fur thereof. In the late 19th century, stoats were introduced into New Zealand to control rabbits. The stoats have had a devastating effect on native bird populations (see stoats in New Zealand).
It is classed by the IUCN as least concern, due to its wide circumpolar distribution, and because it does not face any significant threat to its survival. It was nominated as one of the world's top 100 "worst invaders".
Ermine luxury fur is often used by Catholic monarchs, pontiffs and cardinals, who sometimes use it as the mozetta cape. It is also used in capes on devotional images such as the Infant Jesus of Prague. The parliamentary and coronation robes of British peers of the realm are also made from ermine.

The root word for "stoat" is likely either the Belgic and Dutch word stout ("bold") or the Gothic word stautan ("to push"). According to John Guillim, in his Display of Heraldrie, the word "ermine" is likely derived from Armenia, the nation where it was thought the species originated, though other authors have linked it to the Norman French from the Teutonic harmin (Anglo-Saxon hearma). This seems to come from the Lithuanian word šarmu. In Ireland (where the least weasel does not occur), the stoat is referred to as weasel, while in North America it is called short-tailed weasel. A male stoat is called a dog, hob, or jack, while a female is called a bitch or jill. The collective noun for stoats is either gang or pack.
The stoat's direct ancestor was Mustela palerminea, a common carnivore in central and eastern Europe during the Middle Pleistocene, that spread to North America during the late Blancan or early Irvingtonian. The stoat is the product of a process begun 5–7 million years ago, when northern forests were replaced by open grassland, thus prompting an explosive evolution of small, burrowing rodents. The stoat's ancestors were larger than the current form, and underwent a reduction in size to exploit the new food source. The stoat first arose in Eurasia, shortly after the long-tailed weasel arose as its mirror image in North America 2 million years ago. The stoat thrived during the Ice Age, as its small size and long body allowed it to easily operate beneath snow, as well as hunt in burrows. The stoat and the long-tailed weasel remained separated until half a million years ago, when falling sea levels exposed the Bering land bridge.
Combined phylogenetic analyses indicate the stoat's closest living relative is the mountain weasel (Mustela altaica), though it is also closely related to the least weasel (Mustela nivalis) and long-tailed weasel (Mustela frenata). Its next closest relatives are the New World Colombian weasel (Mustela felipei) and the Amazon weasel (Mustela africana).

The stoat is entirely similar to the least weasel in general proportions, manner of posture, and movement, though the tail is relatively longer, always exceeding a third of the body length, though it is shorter than that of the long-tailed weasel. The stoat has an elongated neck, the head being set exceptionally far in front of the shoulders. The trunk is nearly cylindrical, and does not bulge at the abdomen. The greatest circumference of body is little more than half its length. The skull, although very similar to that of the least weasel, is relatively longer, with a narrower braincase. The projections of the skull and teeth are weakly developed, but stronger than those of the least weasel. The eyes are round, black and protrude slightly. The whiskers are brown or white in colour, and very long. The ears are short, rounded and lie almost flattened against the skull. The claws are not retractable, and are large in proportion to the digits. Each foot has five toes. The male stoat has a curved baculum with a proximal knob that increases in weight as it ages. Fat is deposited primarily along the spine and kidneys, then on gut mesenteries, under the limbs and around the shoulders. The stoat has four pairs of nipples, though they are visible only in females.
The dimensions of the stoat are variable, but not as variable as the least weasel. Unusual among the Carnivora, the size of stoats tends to decrease proportionally with latitude, in contradiction to Bergmann's rule. Sexual dimorphism in size is pronounced, with males being 1.5-2.0 times the weight of females. On average, males measure 187–325 mm (7.4–12.8 in) in body length, while females measure 170–270 mm (6.7–10.6 in). The tail measures 75–120 mm (3.0–4.7 in) in males and 65–106 mm (2.6–4.2 in) in females. In males, the hind foot measures 40.0–48.2 mm (1.57–1.90 in), while in females it is 37.0–47.6 mm (1.46–1.87 in). The height of the ear measures 18.0–23.2 mm (0.71–0.91 in) in males and 14.0–23.3 mm (0.55–0.92 in). The skulls of males measure 39.3–52.2 mm (1.55–2.06 in) in length, while those of females measure 35.7–45.8 mm (1.41–1.80 in). Males weigh 258 grams (9.1 oz), while females weigh less than 180 grams (6.3 oz).
The stoat has large anal scent glands measuring 8.5 mm × 5 mm (0.33 in × 0.20 in) in males and smaller in females. Scent glands are also present on the cheeks, belly and flanks. Epidermal secretions, which are deposited during body rubbing, are chemically distinct from the products of the anal scent glands, which contain a higher proportion of volatile chemicals. When attacked or being aggressive, the stoat secretes the contents of its anal glands, giving rise to a strong, musky odour produced by several sulphuric compounds. The odour is distinct from that of least weasels.
The winter fur is very dense and silky, but quite closely lying and short, while the summer fur is rougher, shorter and sparse. In summer, the fur is sandy-brown on the back and head and a white below. The division between the dark back and the light belly is usually straight, though this trait is only present in 13.5% of Irish stoats. The stoat moults twice a year. In spring, the moult is slow, starting from the forehead, across the back, toward the belly. In autumn, the moult is quicker, progressing in the reverse direction. The moult, initiated by photoperiod, starts earlier in autumn and later in spring at higher latitudes. In the stoat's northern range, it adopts a completely white coat (save for the black tail-tip) during the winter period. Differences in the winter and summer coats are less apparent in southern forms of the species. In the species' southern range, the coat remains brown, but is denser and sometimes paler than in summer.
Reproduction and development
In the Northern Hemisphere, mating occurs in the April–July period. In spring, the male's testes are enlarged, a process accompanied by an increase of testosterone concentration in the plasma. Spermatogenesis occurs in December, and the males are fertile from May to August, after which the testes regress. Stoats are not monogamous, with litters often being of mixed paternity. The gestation period lasts circa 280 days. Males play no part in rearing the young, which are born blind, deaf, toothless and covered in fine white or pinkish down. The milk teeth erupt after three weeks, and solid food is eaten after four weeks. The eyes open after five to six weeks, with the black tail-tip appearing a week later. Lactation ends after 12 weeks. Prior to the age of five to seven weeks, kits have poor thermoregulation, so they huddle for warmth when the mother is absent. Males become sexually mature at 10–11 months, while females are sexually mature at the age of 2–3 weeks whilst still blind, deaf and hairless, and are usually mated with adult males before being weaned.
Territorial and sheltering behaviours
Stoat territoriality has a generally mustelid spacing pattern, with male territories encompassing smaller female territories, which they defend from other males. The size of the territory and the ranging behaviour of its occupants varies seasonally, depending on the abundance of food and mates. During the breeding season, the ranges of females remain unchanged, while males either become roamers, strayers or transients. Dominant older males have territories 50 times larger than those of younger, socially inferior males. Both sexes mark their territories with urine, faeces and two types of scent marks; anal drags are meant to convey territorial occupancy, and body rubbing is associated with agonistic encounters.
The stoat does not dig its own burrows, instead using the burrows and nest chambers of the rodents it kills. The skins and underfur of rodent prey are used to line the nest chamber. The nest chamber is sometimes located in seemingly unsuitable places, such as among logs piled against the walls of houses. The stoat also inhabits old and rotting stumps, under tree roots, in heaps of brushwood, haystacks, in bog hummocks, in the cracks of vacant mud buildings, in rock piles, rock clefts, and even in magpie nests. Males and females typically live apart, but close to each other. Each stoat has several dens dispersed within its range. A single den has several galleries, mainly within 30 cm (12 in) of the surface.
As with the least weasel, mouse-like rodents predominate in the stoat's diet. However, unlike the least weasel, which almost exclusively feeds on small voles, the stoat regularly preys on larger rodent and lagomorph species. In Russia, its prey includes rodents and lagomorphs such as European water voles, common hamsters, pikas, and others, which it overpowers in their burrows. Prey species of secondary importance include small birds, fish, and shrews and, more rarely, amphibians, lizards, and insects. In Great Britain, European rabbits are an important food source, with the frequency in which stoats prey on them having increased between the 1960s and mid 1990s since the end of the myxomatosis epidemic. Typically, male stoats prey on rabbits more frequently than females do, which depend to a greater extent on smaller rodent species. British stoats rarely kill shrews, rats, squirrels and water voles, though rats may be an important food source locally. In Ireland, shrews and rats are frequently eaten. In mainland Europe, water voles make up a large portion of the stoat's diet. Hares are sometimes taken, but are usually young specimens. In North America, where the ecological niche for rat and rabbit sized prey is taken by the larger long-tailed weasel, the stoat preys on mice, voles, shrews, and young cottontails. In New Zealand, the stoat feeds principally on birds, including the rare kiwi, kaka, mohua, yellow-crowned parakeet, and New Zealand dotterel. Cases are known of stoats preying on young muskrats. The stoat typically eats about 50 grams (1.8 oz) of food a day, which is equivalent to 25% of the animal's live weight.
The stoat is an opportunistic predator, which moves rapidly and checks every available burrow or crevice for food. Because of their larger size, male stoats are less successful than females in pursuing rodents far into tunnels. Stoats regularly climb trees to gain access to birds' nests, and are common raiders of nest boxes, particularly those of large species. The stoat reputedly immobilises prey such as rabbits by mesmerising them with a "dance" (sometimes called the weasel war dance), though this behaviour could be linked to Skrjabingylus infections. When tackling large prey, the stoat bites the spine of its target, typically a rabbit, bringing it down by damaging its spine. The stoat may surplus kill when the opportunity arises, though excess prey is usually cached and eaten later to avoid obesity, as overweight stoats tend to be at a disadvantage when pursuing prey into their burrows. Small prey typically die instantly from a bite to the back of the neck, while larger prey, such as rabbits, typically die of shock, as the stoat's canine teeth are too short to reach the spinal column or major arteries.
The stoat is a usually silent animal, but can produce a range of sounds similar to those of the least weasel. Kits produce a fine chirping noise. Adults trill excitedly before mating, and indicate submission through quiet trilling, whining and squealing. When nervous, the stoat hisses, and will intersperse this with sharp barks or shrieks and prolonged screeching when aggressive.
Aggressive behaviour in stoats is categorised in these forms:
- Noncontact approach, which is sometimes accompanied by a threat display and vocalisation from the approached animal
- Forward thrust, accompanied by a sharp shriek, which is usually done by stoats defending a nest or retreat site
- Nest occupation, when a stoat appropriates the nesting site of a weaker individual
- Kleptoparasitism, in which a dominant stoat appropriates the kill of a weaker one, usually after a fight
Submissive stoats express their status by avoiding higher-ranking animals, fleeing from them or making whining or squealing sounds.
Range and population
The stoat has a circumboreal range throughout North America, Europe, and Asia, from Greenland and the Canadian and Siberian Arctic islands south to about 35°N. Stoats in North America are found throughout Alaska and Canada south through most of the northern United States to central California, northern Arizona, northern New Mexico, Iowa, the Great Lakes region, New England, and Pennsylvania, but is absent from most of the Great Plains, and the Southeastern United States. The stoat in Europe is found as far south as 41ºN in Portugal, and inhabits most islands with the exception of Iceland, Svalbard, the Mediterranean islands and some small North Atlantic islands. In Japan, it is present in central mountains (northern and central Japan Alps) to northern part of Honshu (primarily above 1,200 m) and Hokkaido. Its vertical range is from sea level to 3,000 m.
Irish stoats (Mustela erminea hibernica (Thomas & Barrett-Hamilton)) have been recorded in Ireland.
Introduction to New Zealand
Stoats were introduced into New Zealand during the late 19th century to control rabbits and hares, but are now a major threat to native bird populations. The introduction of stoats was opposed by scientists in New Zealand and Britain, including the New Zealand ornithologist Walter Buller. The warnings were ignored and stoats began to be introduced from Britain in the 1880s, resulting in a noticeable decline in bird populations within six years. Stoats are a serious threat to ground- and hole-nesting birds, since they have very few means of escaping predation. The highest rates of stoat predation occur after seasonal gluts in southern beechmast (beechnuts), which encourage the reproduction of rodents on which stoats also feed, encouraging stoats to increase their own numbers. For instance, the endangered takahe's wild population dropped by a third between 2006 and 2007, after a stoat plague triggered by the 2005–06 mast wiped out more than half the takahe in untrapped areas.
Diseases and parasites
Tuberculosis has been recorded in stoats inhabiting the former Soviet Union and New Zealand. They are largely resistant to tularemia, but are reputed to suffer from canine distemper in captivity. Symptoms of mange have also been recorded.
Stoats are vulnerable to ectoparasites associated with their prey and the nests of other animals on which they do not prey. The louse Trichodectes erminea is recorded in stoats living in Canada, Ireland and New Zealand. In continental Europe, 26 flea species are recorded to infest stoats, including Rhadinospylla pentacantha, Megabothris rectangulatus, Orchopeas howardi, Spilopsyllus ciniculus, Ctenophthalamus nobilis, Dasypsyllus gallinulae, Nosopsyllus fasciatus, Leptospylla segnis, Ceratophyllus gallinae, Parapsyllus n. nestoris, Amphipsylla kuznetzovi and Ctenopsyllus bidentatus. Tick species known to infest stoats are Ixodes canisuga, I. hexagonus, and I. ricinus and Haemaphysalis longicornis. Louse species known to infest stoats include Mysidea picae and Polyplax spinulosa. Mite species known to infest stoats include Neotrombicula autumnalis, Demodex erminae, Eulaelaps stabulans, Gymnolaelaps annectans, Hypoaspis nidicorva, and Listrophorus mustelae.
The nematode Skrjabingylus nasicola is particularly serious to stoats, as it erodes the bones of the nasal sinuses and decreases fertility. One symptom includes fits, which may explain the "dancing" behaviour usually associated with hunting. Other nematode species known to infect stoats include Capillaria putorii, Molineus patens and Strongyloides martes. Cestode species known to infect stoats include Taenia tenuicollis, Mesocestoides lineatus and rarely Acanthocephala.
Relationships with humans
Folklore and mythology
In Irish mythology, stoats were viewed anthropomorphically as animals with families, which held rituals for their dead. They were also viewed as noxious animals prone to thieving, and their saliva was said to be able to poison a grown man. To encounter a stoat when setting out for a journey was considered bad luck, but one could avert this by greeting the stoat as a neighbour. Stoats were also supposed to hold the souls of infants who died before baptism. In the folklore of the Komi people of the Urals, stoats are symbolic of beautiful and coveted young women. In the Zoroastrian religion, the stoat is considered a sacred animal, as its white winter coat represented purity. Similarly, Mary Magdalene was depicted as wearing a white stoat pelt as a sign of her reformed character. One popular European legend had it that a white stoat would die before allowing its pure white coat to be besmirched. When it was being chased by hunters, it would supposedly turn around and give itself up to the hunters rather than risk soiling itself. The former nation (now province) of Brittany in France uses a stylized ermine-fur pattern in forming the Coat of Arms and Flag of Brittany.
Stoat skins are prized by the fur trade, especially in winter coat, and used to trim coats and stoles. The fur from the winter coat is referred to as ermine. There is also a design, also called ermine, which is inspired by the winter coat of the stoat but which is painted onto other furs, such as rabbit. In Europe these furs are a symbol of royalty and high status; the ceremonial robes of members of the UK House of Lords and the academic hoods of the universities of Oxford and Cambridge are traditionally trimmed with ermine although in practice rabbit or fake fur is now often used instead due to expense or animal rights concerns. Prelates of the Catholic Church still wear ecclesiastical garments featuring ermine (a sign of their status equal to that of the nobility). Cecilia Gallerani is depicted holding an ermine in her portrait, Lady with an Ermine, by Leonardo da Vinci. Henry Peacham's Emblem 75, which depicts an ermine being pursued by a hunter and two hounds, is entitled "Cui candor morte redemptus" ("Purity bought with his own death"). Peacham goes on to preach that men and women should follow the example of the ermine and keep their minds and consciences as pure as the legendary ermine keeps its fur.
Ermine were also valued by the Tlingit and other indigenous peoples of the Pacific Northwest Coast. They could be attached to traditional regalia and cedar bark hats as status symbols, or they were also made into shirts.
The stoat was a fundamental item in the fur trade of the Soviet Union, with no less than half the global catch coming from within its borders. The Soviet Union also contained the highest grades of stoat pelts, with the best grade North American pelts being comparable only to the 9th grade in the quality criteria of former Soviet stoat standards. However, stoat harvesting never became a specialty in any Soviet republic, with most stoats being captured incidentally in traps or near villages. Stoats in the Soviet Union were captured either with dogs or with box-traps or jaw-traps. Guns were rarely used, as they could damage the pelt.
