European badger

The species likely evolved from the Chinese Meles thorali of the early Pleistocene. The modern species originated during the early Middle Pleistocene, with fossil sites occurring in Episcopia, Grombasek, Süssenborn, Hundsheim, Erpfingen, Koneprusy, Mosbach 2, and Stránská Skála. A comparison between fossil and living specimens shows a marked progressive adaptation to omnivory, namely in the increase in the molars' surface areas and the modification of the carnassials. Occasionally, badger bones are discovered in earlier strata, due to the burrowing habits of the species.[11][12]

In the 19th and 20th centuries, several badger type specimens were described and proposed as subspecies. As of 2005, eight subspecies are recognized as valid taxa.[13]

In winter, the fur on the back and flanks is long and coarse, consisting of bristly guard hairs with a sparse, soft undercoat. The belly fur consists of short, sparse hairs, with skin being visible in the inguinal region. Guard hair length on the middle of the back is 75–80 mm (3.0–3.1 in) in winter. Prior to the winter, the throat, lower neck, chest and legs are black. The belly is of a lighter, brownish tint, while the inguinal region is brownish-grey. The general colour of the back and sides is light silvery-grey, with straw-coloured highlights on the sides. The tail has long and coarse hairs, and is generally the same colour as the back. Two black bands pass along the head, starting from the upper lip and passing upwards to the whole base of the ears. The bands sometimes extend along the neck and merge with the colour of the upper body. The front parts of the bands are 15 mm (0.6 in), and widen to 45–55 mm (1.8–2.2 in) in the ear region. A wide, white band extends from the nose tip through the forehead and crown. White markings occur on the lower part of the head, and extend backwards to a great part of the neck's length. The summer fur is much coarser, shorter and sparser, and is deeper in colour, with the black tones becoming brownish, sometimes with yellowish tinges.[25] Partial melanism in badgers is known, and albinos are not uncommon. Albino badgers can be pure white or yellowish with pink eyes. Erythristic badgers are more common than the former, being characterized by having a sandy-red colour on the usually black parts of the body. Yellow badgers are also known.[42]

European badgers are the most social of badgers,[43] forming groups of six adults on average, though larger associations of up to 23 individuals have been recorded. Group size may be related to habitat composition. Under optimal conditions, badger territories can be as small as 30 ha, but may be as large as 150 ha in marginal areas.[44] Badger territories can be identified by the presence of communal latrines and well-worn paths.[45] It is mainly males that are involved in territorial aggression. A hierarchical social system is thought to exist among badgers and large powerful boars seem to assert dominance over smaller males. Large boars sometimes intrude into neighboring territories during the main mating season in early spring.

Sparring and more vicious fights generally result from territorial defense in the breeding season.[46] However, in general, animals within and outside a group show considerable tolerance of each other. Boars tend to mark their territories more actively than sows, with their territorial activity increasing during the mating season in early spring.[44] Badgers groom each other very thoroughly with their claws and teeth. Grooming may have a social function.[47] They are crepuscular and nocturnal in habits.[47] Aggression among badgers is largely associated with territorial defence and mating. When fighting, they bite each other on the neck and rump, while running and chasing each other and injuries incurred in such fights can be severe and sometimes fatal. When attacked by dogs or sexually excited, badgers may raise their tails and fluff up their fur.[48]

European badgers have an extensive vocal repertoire. When threatened they emit deep growls and when fighting make low kekkering noises. They bark when surprised, whicker when playing or in distress,[48] and emit a piercing scream when alarmed or frightened.[49]

Estrus in European badgers lasts four to six days and may occur throughout the year, though there is a peak in spring. Sexual maturity in boars is usually attained at the age of twelve to fifteen months but this can range from nine months to two years. Males are normally fecund during January–May, with spermatogenesis declining in summer. Sows usually begin ovulating in their second year, though some exceptionally begin at nine months. They can mate at any time of the year, though the main peak occurs in February–May, when mature sows are in postpartal estrus and young animals experience their first estrus. Matings occurring outside this period typically occur in sows which either failed to mate earlier in the year or matured slowly.[50] Badgers are usually monogamous; boars typically mate with one female for life, whereas sows have been known to mate with more than one male.[51] Mating lasts for fifteen to sixty minutes, though the pair may briefly copulate for a minute or two when the sow is not in estrus. A delay of two to nine months precedes the fertilized eggs implanting into the wall of the uterus, though matings in December can result in immediate implantation. Ordinarily, implantation happens in December, with a gestation period lasting seven weeks. Cubs are usually born in mid-January to mid-March within underground chambers containing bedding. In areas where the countryside is waterlogged, cubs may be born above ground in buildings. Typically, only dominant sows can breed, as they suppress the reproduction of subordinate females.[50]

The average litter consists of one to five cubs.[50] Although many cubs are sired by resident males, up to 54% can be fathered by boars from different colonies.[44] Dominant sows may kill the cubs of subordinates.[48] Cubs are born pink, with greyish, silvery fur and fused eyelids. Neonatal badgers are 12 cm (5 in) in body length on average and weigh 75 to 132 grams (2.6 to 4.7 oz), with cubs from large litters being smaller.[50] By three to five days, their claws become pigmented, and individual dark hairs begin to appear.[51] Their eyes open at four to five weeks and their milk teeth erupt about the same time. They emerge from their setts at eight weeks of age, and begin to be weaned at twelve weeks, though they may still suckle until they are four to five months old. Subordinate females assist the mother in guarding, feeding and grooming the cubs.[50] Cubs fully develop their adult coats at six to nine weeks.[51] In areas with medium to high badger populations, dispersal from the natal group is uncommon, though badgers may temporarily visit other colonies.[47] Badgers can live for up to about fifteen years in the wild.[49]

Entrance to a badger sett

Like other badger species, European badgers are burrowing animals. However, the dens they construct (called setts) are the most complex, and are passed on from generation to generation.[52] The number of exits in one sett can vary from a few to fifty. These setts can be vast, and can sometimes accommodate multiple families. When this happens, each family occupies its own passages and nesting chambers. Some setts may have exits which are only used in times of danger or play. A typical passage has a 22–63 cm (8.7–24.8 in) wide base and a 14–32 cm (5.5–12.6 in) height. Three sleeping chambers occur in a family unit, some of which are open at both ends. The nesting chamber is located 5–10 m (5.5–10.9 yd) from the opening, and is situated more than a 1 m (1.1 yd) underground, in some cases 2.3 m (2.5 yd). Generally, the passages are 35–81 m (38–89 yd) long. The nesting chamber is on average 74 cm × 76 cm (29 in × 30 in), and are 38 cm (15 in) high.[53]

Badgers dig and collect bedding throughout the year, particularly in autumn and spring. Sett maintenance is usually carried out by subordinate sows and dominant boars. The chambers are frequently lined with bedding, brought in on dry nights, which consists of grass, bracken, straw, leaves and moss. Up to 30 bundles can be carried to the sett on a single night. European badgers are fastidiously clean animals which regularly clear out and discard old bedding. During the winter, they may take their bedding outside on sunny mornings and retrieve it later in the day.[44] Spring cleaning is connected with the birth of cubs, and may occur several times during the summer to prevent parasite levels building up.[53]

If a badger dies within the sett, its conspecifics will seal off the chamber and dig a new one. Some badgers will drag their dead out of the sett and bury them outside.[54] A sett is almost invariably located near a tree, which is used by badgers for stretching or claw scraping.[55] Badgers defecate in latrines, which are located near the sett and at strategic locations on territorial boundaries or near places with abundant food supplies.[47]

In extreme cases, when there is a lack of suitable burrowing grounds, badgers may move into haystacks in winter.[53] They may share their setts with red foxes or European rabbits. The badgers may provide protection for the rabbits against other predators. The rabbits usually avoid predation by the badgers by inhabiting smaller, hard to reach chambers.[56]

Badgers begin to prepare for winter sleep during late summer by accumulating fat reserves, which reach a peak in October. During this period, the sett is cleaned and the nesting chamber is filled with bedding. Upon retiring to sleep, badgers block their sett entrances with dry leaves and earth. They typically stop leaving their setts once snow has fallen. In Russia, badgers retire for their winter sleep from late October to mid-November and emerge from their setts in March and early April.[57] In areas such as England and Transcaucasia, where winters are less harsh, badgers either forgo winter sleep entirely or spend long periods underground, emerging in mild spells.[49]

The European badger is native to most of Europe and parts of western Asia. In Europe its range includes Albania, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Crete, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Great Britain, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Macedonia, Moldova, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland and Ukraine. In Asia it occurs in Afghanistan, China (Xinjiang), Iran, Iraq and Israel.[1]

The distributional boundary between the ranges of European and Asian badgers is the Volga River, the European species being situated on the western bank. They are common in European Russia, with 30,000 individuals having been recorded there in 1990. They are abundant and increasing throughout their range, partly due to a reduction in rabies in Central Europe. In the UK, badgers experienced a 77% increase in numbers during the 1980s and 1990s.[1] The badger population in Great Britain in 2012 is estimated to be 300,000.[58]

The European badger is found in deciduous and mixed woodlands, clearings, spinneys, pastureland and scrub, including Mediterranean maquis shrubland. It has adapted to life in suburban areas and urban parks, although not to the extent of red foxes. In mountainous areas it occurs up to an altitude of 2,000 metres (6,600 ft).[1][49]

Badger tracking to study their behavior and territories has been done in Ireland using Global Positioning Systems.[59]

European badgers are among the least carnivorous members of the Carnivora;[60] they are highly adaptable and opportunistic omnivores, whose diet encompasses a wide range of animals and plants. Earthworms are their most important food source, followed by large insects, carrion, cereals, fruit and small mammals including rabbits, mice, shrews, moles and hedgehogs. Insect prey includes chafers, dung and ground beetles, caterpillars, leatherjackets, and the nests of wasps and bumblebees. They are able to destroy wasp nests, consuming the occupants, combs, and envelope, such as that of Vespula rufa nests, since thick skin and body hair protect the badgers from stings.[61] Cereal food includes wheat, oats, maize and occasionally barley. Fruits include windfall apples, pears, plums, blackberries, bilberries, raspberries, strawberries, acorns, beechmast, pignuts and wild arum corms.

Occasionally, they feed on medium to large birds, amphibians, small reptiles, including tortoises, snails, slugs, fungi, and green food such as clover and grass, particularly in winter and during droughts.[62] Badgers characteristically capture large numbers of one food type in each hunt. Generally, they do not eat more than 0.5 kg (1.1 lb) of food per day, with young specimens yet to attain one year of age eating more than adults. An adult badger weighing 15 kg (33 lb) eats a quantity of food equal to 3.4% of its body weight.[60] Badgers typically eat prey on the spot, and rarely transport it to their setts. Surplus killing has been observed in chicken coops.[47]

Badgers prey on rabbits throughout the year, especially during times when their young are available. They catch young rabbits by locating their position in their nest by scent, then dig vertically downwards to them. In mountainous or hilly districts, where vegetable food is scarce, badgers rely on rabbits as a principal food source. Adult rabbits are usually avoided, unless they are wounded or caught in traps.[63] They consume them by turning them inside out and eating the meat, leaving the inverted skin uneaten.[64] Hedgehogs are eaten in a similar manner.[63] In areas where badgers are common, hedgehogs are scarce.[43] Some rogue badgers may kill lambs[63], though this is very rare; they may be erroneously implicated in lamb killings through the presence of discarded wool and bones near their setts, though foxes, which occasionally live alongside badgers, are often the culprits, as badgers do not transport food to their earths. They typically kill lambs by biting them behind the shoulder[63]. Poultry and game birds are also taken only rarely. Some badgers may build their setts in close proximity to poultry or game farms without ever causing damage. In the rare instances in which badgers do kill reared birds, the killings usually occur in February–March, when food is scarce due to harsh weather and increases in badger populations. Badgers can easily breach bee hives with their jaws, and are mostly indifferent to bee stings, even when set upon by swarms.[63]

European badgers have few natural enemies. While normally docile, Badgers can become extremely aggressive and ferocious when cornered, making it dangerous for predators to target them. Grey wolves (Canis lupus), Eurasian lynxes (Lynx lynx) and brown bears (Ursus arctos), Europe's three largest remaining land predators, and large domestic dogs (C. l. familiaris) can pose a threat to adult badgers, though deaths caused by them are quantitatively rare as these predators are often limited in population due to human persecution and usually prefer easier, larger prey like ungulates, while badgers may fight viciously if aware of a predator and cornered without an escape route.[65][66][67][68] They may live alongside red foxes (Vulpes vulpes) in isolated sections of large burrows.[54] The two species possibly tolerate each other out of commensalism; foxes provide badgers with food scraps, while badgers maintain the shared burrow's cleanliness.[69] However, cases are known of badgers driving vixens from their dens and destroying their litters without eating them.[54] In turn, very large male red foxes are known to have killed badgers in spring.[70] Golden eagles (Aquila chrysaetos) are known predators of European badgers and attacks by them on badger cubs are not infrequent, including cases where they've been pulled out directly from below the legs of their mothers, and even adult badgers may be attacked by this eagle when emerging weak and hungry from hibernation.[71][72] Eurasian eagle owls (Bubo bubo) may also take an occasional cub and other large raptors such as white-tailed eagles (Haliaeetus albicilla) and greater spotted eagle (Clanga clanga) are considered potential badger cub predators.[65][68][73] Raccoon dogs may extensively use badger setts for shelter. There are many known cases of badgers and raccoon dogs wintering in the same hole, possibly because badgers enter hibernation two weeks earlier than the latter, and leave two weeks later. In exceptional cases, badger and raccoon dog cubs may coexist in the same burrow. Badgers may drive out or kill raccoon dogs if they overstay their welcome.[74]

Badgers play a part in European folklore and are featured in modern literature. In Irish mythology, badgers are portrayed as shape-shifters and kinsmen to Tadg, the king of Tara and foster father of Cormac mac Airt. In one story, Tadg berates his adopted son for having killed and prepared some badgers for dinner.[79] In German folklore, the badger is portrayed as a cautious, peace-loving Philistine, who loves more than anything his home, family and comfort, though he can become aggressive if surprised. He is a cousin of Reynard the Fox, whom he uselessly tries to convince to return to the path of righteousness.[8]

In Kenneth Graham's The Wind in the Willows, Mr. Badger is depicted as a gruff, solitary figure who "simply hates society", yet is a good friend to Mole and Ratty. As a friend of Toad's now-deceased father, he is often firm and serious with Toad, but at the same time generally patient and well-meaning towards him. He can be seen as a wise hermit, a good leader and gentleman, embodying common sense. He is also brave and a skilled fighter, and helps rid Toad Hall of invaders from the wild wood.[80]

The "Frances" series of children's books by Russell and Lillian Hoban depicts an anthropomorphic badger family.

In T.H. White's Arthurian series The Once and Future King, the young King Arthur is transformed into a badger by Merlin as part of his education. He meets with an older badger who tells him "I can only teach you two things – to dig, and love your home." [81]

A villainous badger named Tommy Brock appears in Beatrix Potter's 1912 book The Tale of Mr. Tod. He is shown kidnapping the children of Benjamin Bunny and his wife Flopsy, and hiding them in an oven at the home of Mr. Tod the fox, whom he fights at the end of the book. The portrayal of the badger as a filthy animal which appropriates fox dens was criticized from a naturalistic viewpoint, though the inconsistencies are few and employed to create individual characters rather than evoke an archetypical fox and badger.[82] A wise old badger named Trufflehunter appears in C. S. Lewis' Prince Caspian, where he aids Caspian X in his struggle against King Miraz.[83]

A badger takes a prominent role in Colin Dann's The Animals of Farthing Wood series as second in command to Fox.[84] The badger is also the house symbol for Hufflepuff in the Harry Potter book series.[85] The Redwall series also has the Badger Lords, who rule the extinct volcano fortress of Salamandastron and are renowned as fierce warriors.[86] The children's television series Bodger & Badger was popular on CBBC during the 1990s and was set around the mishaps of a mashed potato-loving badger and his human companion.[87]

An unnamed badger is part of Bosnian writer Petar Kočić's satirical play Badger on Tribunal in which local farmer David Štrbac attempts to sue a badger for eating his crops. It is actually highly critical towards Austro-Hungarian rule in Bosnia and Herzegovina at the beginning of 20th century. In honor of Kočić and his Badger, satirical theater in Banja Luka is named Jazavac (Badger).

European badgers are of little significance to hunting economies, though they may be actively hunted locally. Methods used for hunting badgers include catching them in jaw traps, ambushing them at their setts with guns, smoking them out of their earths and through the use of specially bred dogs such as Fox Terriers and Dachshunds to dig them out.[88] Badgers are, however, notoriously durable animals; their skins are thick, loose and covered in long hair which acts as protection, and their heavily ossified skulls allow them to shrug off most blunt traumas, as well as shotgun pellets.[89]

Badger-baiting was once a popular blood sport,[90] in which badgers were captured alive, placed in boxes, and attacked with dogs.[91] In the UK, this was outlawed by the Cruelty to Animals Act of 1835[91] and again by the Protection of Animals Act of 1911.[92] Moreover, the cruelty towards and death of the badger constitute offences under the Protection of Badgers Act 1992,[93] and further offences under this act are inevitably committed to facilitate badger-baiting (such as interfering with a sett, or the taking or the very possession of a badger for purposes other than nursing an injured animal to health). If convicted, badger-baiters may face a sentence of up to six months in jail, a fine of up to £5,000, and other punitive measures, such as community service or a ban from owning dogs.[94]

Many badgers in Europe were gassed during the 1960s and 1970s to control rabies.[95] Until the 1980s, badger culling in the United Kingdom was undertaken in the form of gassing, to control the spread of bovine tuberculosis (bTB). Limited culling resumed in 1998 as part of a 10-year randomized trial cull which was considered by John Krebs and others to show that culling was ineffective. Some groups called for a selective cull,[96] while others favoured a programme of vaccination, and vets support the cull on compassionate grounds as they say that the illness causes much suffering in badgers.[96] In 2012, the government authorized a limited cull[97] led by the Department for Environment, Food and Rural Affairs (Defra), however, this was later deferred with a wide range of reasons given.[98] In August 2013, a full culling programme began where about 5,000 badgers were killed over six weeks in West Somerset and Gloucestershire by marksmen with high-velocity rifles using a mixture of controlled shooting and free shooting (some badgers were be trapped in cages first). The cull caused many protests with emotional, economic and scientific reasons being cited. The badger is considered an iconic species of the British countryside, though is not endangered. It was claimed by shadow ministers that "The government's own figures show it will cost more than it saves...", and Lord Krebs, who led the Randomised Badger Culling Trial in the 1990s, said the two pilots "will not yield any useful information".[99] A scientific study of culling from 2013–2017 has shown a reduction of 36–55% incidence of bovine tuberculosis in cattle.[2]

There are several accounts of European badgers being tamed. Tame badgers can be affectionate pets, and can be trained to come to their owners when their names are called. They are easily fed, as they are not fussy eaters, and will instinctively unearth rats, moles and young rabbits without training, though they do have a weakness for pork. Although there is one record of a tame badger befriending a fox, they generally do not tolerate the presence of cats and dogs, and will chase them.[100]

Badger meat is eaten in some districts of the former Soviet Union, though in most cases it is discarded.[88] Smoked hams made from badgers were once highly esteemed in England, Wales and Ireland.[101]

Some badger products have been used for medical purposes; badger expert Ernest Neal, quoting from an 1810 edition of The Sporting Magazine, wrote;

'The flesh, blood and grease of the badger are very useful for oils, ointments, salves and powders, for shortness of breath, the cough of the lungs, for the stone, sprained sinews, collachs etc. The skin being well dressed is very warm and comfortable for ancient people who are troubled with paralytic disorders.'[101]

The hair of the European badger has been used for centuries for making sporrans[101] and shaving brushes.[90][102] Sporrans are traditionally worn as part of male Scottish highland dress. They form a bag or pocket made from a pelt and a badger or other animal's mask may be used as a flap.[103] The pelt was also formerly used for pistol furniture.[90]
