Global golden jackal range based on IUCN's 2018 assessment.
Thegolden jackal (Canis aureus), also called thecommon jackal, is awolf-like canid that is native toEurasia. The golden jackal's coat varies in color from a pale creamy yellow in summer to a dark tawny beige in winter. It is smaller and has shorter legs, a shorter tail, a more elongated torso, a less-prominent forehead, and a narrower and more pointed muzzle than theArabian wolf. It is listed asLeast Concern on theIUCN Red List due to its widespread distribution and high density in areas with plenty of available food and optimum shelter.
Despite its name, the golden jackal is not closely related to the Africanblack-backed jackal orside-striped jackal, which are part of the genusLupulella. It is instead closer towolves andcoyotes. The ancestor of the golden jackal is believed to be the extinctArno river dog that lived insouthern Europe1.9 million years ago. It is described as having been a small, jackal-like canine. Genetic studies indicate that the golden jackal expanded from India around 20,000 years ago, towards the end of the lastLast Glacial Maximum. The oldest golden jackal fossil, found at theKsar Akil rock shelter nearBeirut, Lebanon, is 7,600 years old. The oldest golden jackal fossils in Europe were found in Greece and are 7,000 years old. There are sixsubspecies of the golden jackal. It is capable of producing fertilehybrids with both the gray wolf and the African wolf.Jackal–dog hybrids calledSulimov dogs are in service at theSheremetyevo Airport near Moscow, where they are deployed by the Russian airlineAeroflot for scent-detection.
The golden jackal is abundant in valleys and beside rivers and their tributaries, canals, lakes, and seashores; however, the species is rare in foothills and low mountains. It is a social species, the basic social unit of which consists of a breeding pair and any young offspring. It is very adaptable, with the ability to exploit food ranging from fruit and insects to smallungulates. It attacks domestic fowl and domestic mammals up to the size of domesticwater buffalo calves. Its competitors are thered fox,steppe wolf,jungle cat,Caucasian wildcat, theraccoon in the Caucasus and in Central Asia, and theAsiatic wildcat. It is expanding beyond its native grounds in Southeast Europe intoCentral andNortheast Europe into areas where there are few or no wolves.
The word 'jackal' appeared in theEnglish language around 1600. It derives from the Turkish wordçakal, which originates from the Persian wordšagāl.[3] It is also known as thecommon jackal.[4]
The biological familyCanidae is composed of theSouth American canids, thefox-like canids, and thewolf-like canids.[5] All species within the wolf-like canids share a similar morphology and possess 78chromosomes, allowing them potentially tointerbreed.[6] Within the wolf-like canids is the jackal group, which includes the three jackals: theblack-backed jackal (Lupulellamesomela), theside-striped jackal (Lupulellaadusta), and the golden jackal (Canis aureus). These three species are approximately the same size, possess similar dental and skeletal morphology, and are identified from each other primarily by their coat color. They were once thought to have different distributions across Africa with their ranges overlapping inEast Africa (Ethiopia, Kenya, and Tanzania).[7] Although the jackal group has traditionally been considered as homogenous, genetic studies show that jackals are notmonophyletic (they do not share a common ancestor),[8][9][10] and they are only distantly related.[10] The accuracy of the colloquial name "jackal" to describe all jackals is therefore questionable.[8]
Mitochondrial DNA (mDNA) passes along the maternal line and can date back thousands of years.[11] Thus,phylogenetic analysis of mDNA sequences within a species provides a history of maternal lineages that can be represented as aphylogenetic tree.[12][13] A 2005 genetic study of the canids found that thegray wolf anddog are the most closely related on this tree. The next most closely related are thecoyote (Canis latrans), golden jackal, andEthiopian wolf (Canis simensis), which have all been shown tohybridize with the dog in the wild. The next closest are thedhole (Cuon alpinus) andAfrican wild dog (Lycaon pictus), which are not members of genusCanis. These are followed by the black-backed and side-striped jackals, members of the genusLupulella and the mostbasal members of thisclade.[14]
Results from two recent studies of mDNA from golden jackals indicate that the specimens from Africa are genetically closer to the gray wolf than are the specimens from Eurasia.[8][15] In 2015 a major DNA study of golden jackals concluded that the sixC.aureus subspecies found in Africa should be reclassified under the new speciesC.anthus (African wolf),[16][17][18] reducing the number of golden jackal subspecies to seven. The phylogenetic tree generated from this study shows the golden jackal diverging from the wolf/coyote lineage 1.9million years ago and the African wolf diverging 1.3million years ago. The study found that the golden jackal and the African wolf shared a very similar skull and body morphology and that this had confused taxonomists into regarding these as one species. The study proposes that the very similar skull and body morphology is due to both species having originated from a larger common ancestor.[16]
TheArno river dog (Canis arnensis) is an extinct species ofcanine that was endemic toMediterranean Europe during theEarly Pleistocene around 1.9million years ago. It is described as a small jackal-like dog and probably the ancestor of modern jackals.[19] Its anatomy and morphology relate it more to the modern golden jackal than to the two African jackal species,[20][21] the black-backed jackal and the side-striped jackal.[20]
The oldest golden jackal fossil was found at theKsar Akil rock shelter located 10 km (6.2 mi) northeast ofBeirut, Lebanon. The fragment of a single tooth is dated approximately 7,600 years ago.[22] The oldest golden jackal fossils found in Europe are fromDelphi and Kitsos in Greece and are dated 7,000–6,500 years ago.[23] An unusual fossil of a heel bone found inAzykh Cave, inNagorno-Karabakh, dates to theMiddle Pleistocene and is described as probably belonging to the golden jackal, but its classification is not clear. The fossil is described as being slightly smaller and thinner than thecave lynx, similar to the fox, but too large, and similar to the wolf, but too small. As the golden jackal falls between these two in size, the fossil possibly belongs to a golden jackal.[21] The absence of clearly identified golden jackal fossils in theCaucasus region andTranscaucasia, areas where the species currently resides, indicates that the species is a relatively recent arrival.[24]
Ahaplotype is a group ofgenes found in an organism that is inherited from one of its parents.[25][26] Ahaplogroup is a group of similar haplotypes that share a singlemutation inherited from their common ancestor.[11] The mDNA haplotypes of the golden jackal form two haplogroups: the oldest haplogroup is formed by golden jackals from India, and the other, younger, haplogroup diverging from this includes golden jackals from all of the other regions.[27] Indian golden jackals exhibit the highestgenetic diversity, and those from northern and western India are the mostbasal, which indicates that India was the center from which golden jackals spread. The extant golden jackal lineage commenced expanding its population in India 37,000 years ago. During the Last Glacial Maximum, 25,000 to 18,000 years ago, the warmer regions of India andSoutheast Asia provided a refuge from colder surrounding areas. At the end of the Last Glacial Maximum and the beginning of the warming cycles, the golden jackal lineage expanded out of India and into Eurasia to reach the Middle East and Europe.[28]
Outside of India, golden jackals in the Caucasus and Turkey demonstrate the next highest genetic diversity,[27] while those in Europe indicate low genetic diversity,[29][30] confirming their more recent expansion into Europe.[31] Genetic data indicates that the golden jackals of thePeloponnese Peninsula in Greece and theDalmatian coast in Croatia may represent two ancient European populations from 6,000 years ago that have survived into modern times.Jackals were absent from most of Europe until the 19th century, when they started to expand slowly. Jackals were recorded in Hungary with the nearest population known at that time being found in Dalmatia, some 300 kilometers away. This was followed by rapid expansion of jackals towards the end of the 20th century. Golden jackals from bothSoutheast Europe and the Caucasus are expanding into theBaltic. In the Middle East, golden jackals from Israel have a higher genetic diversity than European jackals. This is thought to be due to Israeli jackals havinghybridized with dogs, gray wolves, and African golden wolves,[31] creating ahybrid zone in Israel.[16]
Genetic analysis reveals that mating sometimes occurs between female jackals and gray wolves, producing jackal-wolf hybrids that experts cannot visually distinguish from wolves.[32][33] Hybridization also occurs between female golden jackals and male dogs, which produces fertile offspring,[34] ajackal–dog hybrid. There was 11–13% of ancientgene flow into the golden jackal from the population that was ancestral to wolves and dogs, and an additional 3% from extant wolf populations.[35][36] Up to 15% of the Israeli wolfgenome is derived from admixture with golden jackals in ancient times.[35]
In 2018,whole genome sequencing was used to compare members of the genusCanis. The study supports theAfrican wolf being distinct from the golden jackal, and with theEthiopian wolf being geneticallybasal to both. There is evidence of gene flow between African golden wolves, golden jackals, and graywolves. One African wolf from the EgyptianSinai Peninsula showed high admixture with the Middle Eastern gray wolves and dogs, highlighting the role of the land bridge between the African and Eurasian continents in canid evolution. There was evidence of gene flow between golden jackals and Middle Eastern wolves, less so with European and Asian wolves, and least with North American wolves. The study proposes that the golden jackal ancestry found in North American wolves may have occurred before the divergence of the Eurasian and North American wolves.[37]
Large, with soft, pale fur with predominantly sandy tones.[40] The general color of the outer fur is usually black and white, while the underfur varies from pale brown to pale slate-grey. Occasionally, the nape and shoulders are of a buff color. The ears and front legs are buff, sometimes tan, while the feet are pale. The hind legs are more deeply tinted above the hocks. The chin and forethroat are usually whitish. Weight varies geographically, ranging around 8–10 kg (18–22 lb). In areas where it borders the range of the larger, more richly coloredIndian jackal (particularly the area ofKumaun inIndia), animals of intermediate size and color sometimes appear.[41]
The Indochinese jackal (also known as the Siamese jackal and the Southeast Asian golden jackal)[42] has been disputed as a separate subspecies by some authors who state that its classification is based solely on observations of captive animals. In 2023, an mDNA study indicated that it was an early branching lineage of golden jackal which supports it being a subspecies.[44] It is smaller thanC. a. indicus,[45] weighing up to 8 kg (18 lb). Its fur closely resembles that of adog. It inhabits mountainous areas, nearfarms or residentialforests, and its prey include small animals likebirds,reptiles andfrogs, besides occasionally eating fruits.[46] One seller of two trapped jackals claimed that they killed ten piglets on his farm.[47] It can be active in bothday andnight. Siamese jackals are solitary creatures, but a male and female will cooperate during mating season. It has few natural predators, thoughdholes are a major source of mortality.[46]
Its fur is a mixture of black and white, with buff on the shoulders, ears and legs. The buff color is more pronounced in specimens from high altitudes. Black hairs predominate on the middle of the back and tail. The belly, chest and the sides of the legs are creamy white, while the face and lower flanks are grizzled with gray fur. Adults grow to a length of 100 cm (39 in), 35–45 cm (14–18 in) in height and 8–11 kg (18–24 lb) in weight.[51]
The largest golden jackal subspecies, animals of both sexes average 120–125 cm (47–49 in) in total length and 10–15 kg (22–33 lb) in body weight.[24][54] The fur is coarse, and is generally brightly colored with blackish tones on the back. The thighs, upper legs, ears and forehead are bright-reddish chestnut.[40]
Southeastern Europe,Moldova, Asia Minor and the Caucasus[40]
Measures 67–74 cm (26–29 in) in length and weighs 5–8.6 kg (11–19 lb). The winter coat is shorter, smoother and not as shaggy as that ofindicus. The coat is also darker on the back, being black and speckled with white. The underside is more pigmented on the chin, hind throat, chest and forebelly, while the limbs are rusty ochreous or a rich tan. Molting occurs earlier in the season than withindicus, and the pelt generally does not lighten in color.[57]
Distinguished by its brown ears. The body fur is a yellow on the back, lighter on the sides, and whitish-yellow underneath.[60] A dark band runs from the nose to the end of the tail. Measures 60–90 cm (24–35 in) in body length, 20–30 cm (7.9–11.8 in) in tail length, 15–18 cm (5.9–7.1 in) in head length, and weighs 5–12 kg (11–26 lb).[61]
The golden jackal is similar to the gray wolf but is distinguished by its smaller size, lighter weight, more elongated torso, less-prominent forehead, shorter legs and tail, and a muzzle that is narrower and more pointed.[62] The legs are long in relation to its body, and the feet are slender with small pads.[4] Males measure 71–85 cm (28–33 in) in body length and females 69–73 cm (27–29 in). Males weigh 6–14 kg (13–31 lb) and females weigh 7–11 kg (15–24 lb). The shoulder height is 45–50 cm (18–20 in) for both.[62] In comparison, the smallest wolf is theArabian wolf (Canis lupus arabs), which weighs on average 20 kg (44 lb).[63]
Lateral and dorsal aspects of skull
The skull is most like that of thedingo, and is closer to that of the coyote (C.latrans) and the gray wolf (C.lupus) than to that of the black-backed jackal (L.mesomalas), the side-striped jackal (L.adustus), and the Ethiopian wolf (C.simensis).[64] Compared with the wolf, the skull of the golden jackal is smaller and less massive, with a lower nasal region and shorter facial region; the projections of the skull are prominent but weaker than those of the wolf; thecanine teeth are large and strong but relatively thinner; and itscarnassial teeth are weaker.[62] The golden jackal is a less specialized species than the gray wolf, and these skull features relate to the jackal's diet of smallbirds,rodents, small vertebrates, insects, carrion,[65] fruit, and some vegetable matter.[64] It was once thought that golden jackals could develop a horny growth on the skull referred to as a "jackal's horn" which usually measured approximately 13 mm (1⁄2 in) in length and was concealed by fur.[66] Although no evidence of its existence has been found, belief in it remains common in South Asia.[67][68][69][70] This feature was once associated with magical powers by the people ofSri Lanka.[66]
The jackal's fur is coarse and relatively short,[64] with the base color golden, varying seasonally from a pale creamy yellow to a dark tawny. The fur on the back is composed of a mixture of black, brown, and white hairs, sometimes giving the appearance of the dark saddle like that seen on the black-backed jackal. The underparts are a light pale ginger to cream color. Individual specimens can be distinguished by their unique light markings on the throat and chest.[4] The coats of jackals from high elevations tend to be more buff-colored than those of their lowland counterparts[51] while those of jackals in rocky, mountainous areas may exhibit a grayer shade. The bushy tail has a tan to black tip.[4]Melanism can cause a dark-colored coat in some golden jackals, a coloring once fairly common in Bengal.[71] Unlike melanistic wolves and coyotes that received their dark pigmentation from interbreeding with domestic dogs, melanism in golden jackals probably stems from an independent mutation that could be an adaptive trait.[72] What is possibly an albino specimen was photographed in southeastern Iran during 2012.[73]
The jackalmoults twice a year, in spring and in autumn. In Transcaucasia andTajikistan, the spring moult begins at the end of winter. If the winter has been warm, the spring moult starts in the middle of February; if the winter has been cold, it begins in the middle of March. The spring moult lasts for 60–65 days; if the animal is sick, it loses only half of its winter fur. The spring moult commences with the head and limbs, extends to the flanks, chest, belly and rump, and ends at the tail. Fur on the underparts is absent. The autumn moult occurs from mid-September with the growth of winter fur; the shedding of the summer fur occurs at the same time. The development of the autumn coat starts with the rump and tail and spreads to the back, flanks, belly, chest, limbs and head, with full winter fur being attained at the end of November.[74]
The golden jackal inhabits Europe and Southwest, Central, South, and Southeast Asia.[4][38][75][76][77] The golden jackal'somnivorous diet allows it to eat a large range of foods; this diet, together with its tolerance of dry conditions, enables it to live in different habitats. The jackal's long legs and lithe body allow it to trot over great distances in search of food. It is able to go without water for extended periods and has been observed on islands that have no fresh water.[4] Jackals are abundant in valleys and along rivers and their tributaries, canals, lakes, and seashores, but are rare in foothills and low mountains. In Central Asia they avoid waterless deserts and cannot be found in theKarakum Desert nor theKyzylkum Desert, but can be found at their edges or inoases.[78] On the other hand, in India they can be found living in theThar Desert.[1] They are found in dense thickets of prickly bushes, reed flood-lands and forests. They have been known to ascend over 1,000 m (3,300 ft) up the slopes of theHimalayas; they can withstand temperatures as low as −25 °C (−13 °F) and sometimes −35 °C (−31 °F). They are not adapted to snow, and in snow country they must travel along paths made by larger animals or humans. In India, they will occupy the surrounding foothills above arable areas,[78] entering human settlements at night to feed on garbage, and have established themselves around hill stations at 2,000 m (6,600 ft)height above mean sea level.[4]
They generally avoid mountainous forests, but may enter alpine and sub-alpine areas during dispersal. In Turkey, the Caucasus, and Transcaucasia they have been observed up to 1,000 m (3,300 ft) above mean sea level, particularly in areas where the climate supports shrublands in high elevations.[24] The Estonian population, which marks the only population of this species adapted to theboreal region, largely inhabits coastalgrasslands,alvars, andreed beds, habitats where wolves are seldom present.[79] In Finland, a golden jackal has been trapped nearSodankylä within theArctic Circle.[80]
The golden jackal fills much the same ecological niche in Eurasia as thecoyote does inNorth America;[81] it is both a predator and a scavenger,[82] and an omnivorous and opportunistic forager with a diet that varies according to its habitat and the season. InKeoladeo National Park, India, over 60% of its diet was measured to consist of rodents, birds, and fruit. In theKanha Tiger Reserve, 80% of its diet consists of rodents,reptiles and fruit. Vegetable matter forms part of the jackal diet, and in India they feed intensively on the fruits ofbuckthorn,dogbane,Java plum, and the pods ofmesquite and thegolden rain tree. The jackal scavenges off the kills made by the lion, tiger, leopard, dhole, and gray wolf. In some regions of Bangladesh and India, golden jackals subsist by scavenging on carrion and garbage, and willcache extra food by burying it.[4] The Irish novelist, playwright and poet,Oliver Goldsmith, wrote about the golden jackal:
... Although the species of the wolf approaches very near to that of the dog, yet the jackal seems to be placed between them; to the savage fierceness of the wolf it adds the impudent familiarity of the dog ... It is more noisy in its pursuits even than the dog, and more voracious than the wolf.
InDalmatia, the golden jackal's diet consists of mammals, fruits, vegetables, insects, birds and their eggs, grasses and leaves.[84] Golden jackals change their diet to more readily available foods. In Serbia, their diet is primarily livestock carcasses that are increasingly prevalent due to a lack of removal, and this may have led to the expansion of their population.[85] In Hungary, 55% of their diet is composed ofcommon voles andbank voles, and 41% is composed ofwild boar carcasses.[86] Information on the diet of the golden jackal in northeastern Italy is scant, but it is known to prey on smallroe deer and hares.[24] In Israel, golden jackals are significant predators of snakes; during a poisoning campaign against golden jackals there was an increase in human snakebite reports, but a decrease when the poisoning ceased.[87]
Male golden jackal interacting with a femalered fox and its kits in south-western Germany
The jackal's competitors are the red fox, wolf, jungle cat, wildcat, and raccoon in the Caucasus, and the steppe wildcat in Central Asia.[74] Wolves dominate jackals, and jackals dominate foxes.[54] In 2017 in Iran, anIndian wolf under study killed a golden jackal.[88] In Europe, the range of wolves and jackals is mutually exclusive, with jackals abandoning their territory with the arrival of a wolf pack. One experiment used loudspeakers to broadcast the calls of jackals, and this attracted wolves at a trotting pace to chase away the perceived competitors. Dogs responded to these calls in the same way while barking aggressively. Unleashed dogs have been observed to immediately chase away jackals when the jackals were detected.[54] In Europe, there are an estimated 12,000 wolves. The jackal's recent expansion throughout eastern and western Europe has been attributed to the extermination of the local wolf populations. The present diffusion of the jackal into the northern Adriatic hinterland is in areas where the wolf is absent or very rare.[77][89] In the past, jackals competed with tigers andleopards, feeding on the remains of their kills and, in one case, on a dead tiger. Leopards and tigers once hunted jackals, but today, the leopard is rare, and the tiger is extinct in the jackal's range.[74]Eurasian lynxes have also been known to hunt jackals.[90]
Red foxes and golden jackals share similar diets. Red foxes fear jackals, which are three times bigger than them. Red foxes will avoid close proximity to jackals and fox populations decrease where jackals are abundant.[91] Foxes can be found only at the fringes of jackal territory.[54] There is however one record of a male golden jackal interacting peacefully with multiple red foxes in southwestern Germany.[92]
Striped hyenas prey on golden jackals, and three jackal carcasses were found in one hyena den.[4]
A 2022 study indicated that the presence of golden jackals in portions of Eastern Europe leads to a decrease in the population of invasiveraccoon dogs (Nyctereutes procyonoides), indicating a potentially positive consequence of the jackal colonization of Europe.[79]
Golden jackals exhibit flexible social organization depending on the availability of food. Thebreeding pair is the basic social unit, and they are sometimes accompanied by their current litter of pups. In India, their distributions are a single jackal, 31%, two jackals, 35%, three jackals, 14%, and more than three jackals, 20%.[4] Family groups of up to 4–5 individuals have been recorded.[102]Scent marking through urination and defecation is common around golden jackal den areas and on the trails they most often use. Scent marking is thought to assist in territorial defense. The hunting ranges of several jackals can overlap. Jackals can travel up to 12–15 km (7.5–9.3 mi) during a single night in search of either food or more suitable habitat. Non-breeding members of a pack may stay near a distant food source, such as a carcass, for up to several days before returning to their home range. Home range sizes can vary between 1–20 km2 (0.39–7.72 sq mi), depending on the available food.[4]
Scent marking in Keoladeo National Park
Social interactions such as greetings,grooming, and grouphowling are common in jackals. Howling is more frequent between December and April whenpair bonds are being formed and breeding occurs, which suggests howling has a role in the delineation of territory and for defense.[4] Adult jackals howl standing and the young or subordinate jackals howl sitting.[89] Jackals are easily induced to howl and a single howl may solicit replies from several jackals in the vicinity. Howling begins with 2–3 low-pitched calls that rise to high-pitched calls.[4] The howl consists of a wail repeated 3–4 times on an ascending scale, followed by three short yelps.[57] Jackals typically howl at dawn and in the evening, and sometimes at midday. Adults may howl to accompany the ringing of church bells, with their young responding to sirens or the whistles of steam engines and boats.[103] Social canids such as golden jackals, wolves, and coyotes respond to human imitations of their howls.[104] When there is a change in the weather, jackals will produce a long and continuous chorus.[103] Dominant canids defend their territories against intruders with either a howl to warn them off, approach and confront them, or howl followed by an approach. Jackals, wolves and coyotes will always approach a source of howling.[105] Golden jackals give a warning call that is very different from their normal howling when they detect the presence of large carnivores such as wolves and tigers.[4][57]
Golden jackals are monogamous and will remain with the one partner until death.[106] Female jackals have only one breeding cycle each year. Breeding occurs from October to March in Israel and from February to March in India, Turkmenistan,[4] Bulgaria, and Transcaucasia, with the mating period lasting up to 26–28 days. Females undergoing their first estrus are often pursued by several males that may quarrel among themselves.[106] Mating results in a copulatory tie that lasts for several minutes, as it does with all other canids. Gestation lasts 63 days, and the timing of the births coincides with the annual abundance of food.[4]
In India, the golden jackal will take over the dens of theBengal fox and theIndian crested porcupine, and will use abandoned gray wolf dens.[4] Most breeding pairs are spaced well apart and maintain a core territory around their dens. Den excavations commence from late April to May in India, with dens located in scrub areas. Rivulets, gullies, and road and check-dam embankments are prime denning habitats. Drainage pipes and culverts have been used as dens. Dens are 2–3 m (6.6–9.8 ft) long and 0.5–1 m (1.6–3.3 ft) deep, with between 1–3 openings. Young pups can be moved between 2–4 dens.[4] The male helps with digging the den and raising the pups.[106] In the Caucasus and Transcaucasia, the burrow is located either in thick shrub, on the slopes of gullies, or on flat surfaces. InDagestan andAzerbaijan, litters are sometimes located within the hollows of fallen trees, among tree roots, and under stones on river banks. In Central Asia, the golden jackal does not dig burrows but constructs lairs in densetugai thickets. Jackals in the tugais and cultivated lands of Tajikistan construct lairs in long grass, shrubs, and reed openings.[102]
Syrian jackal (C. a. syriacus) pup at the entrance to its den,Yarkon Park, Israel
In Transcaucasia, golden jackal pups are born from late March to late April,[106] and in northeastern Italy during late April;[24] they can be born at any time of year in Nepal.[51] The number of pups born in a single litter varies geographically. Jackals in Transcaucasia give birth to 3–8 pups, Tajikistan 3–7 pups,Uzbekistan 2–8 pups, and Bulgaria 4–7 pups; in India the average is four pups.[106] The pups are born with closed eyes that open after 8–11 days, with the ears erecting after 10–13 days.[74] Their teeth erupt at 11 days after birth,[4] and the eruption ofadult dentition is completed after five months. Pups are born with soft fur that ranges in color from light gray to dark brown. At the age of one month, their fur is shed and replaced with a new reddish-colored pelt with black speckles. The pups have a fast growth rate and weigh 0.201–0.214 kg (0.44–0.47 lb) at two days of age, 0.560–0.726 kg (1.23–1.60 lb) at one month, and 2.700–3.250 kg (5.95–7.17 lb) at four months.[74] Females possess four pairs of teats, andlactation lasts for up to 8–10 weeks.[4] The pups begin to eat meat at the age of 15–20 days.[74]
Dog pups show unrestrained fighting with their siblings from 2 weeks of age, with injury avoided only due to their undeveloped jaw muscles. This fighting gives way to play-chasing with the development of running skills at 4–5 weeks. Wolf pups possess more-developed jaw muscles from 2 weeks of age, when they first show signs of play-fighting with their siblings; serious fighting occurs during 4–6 weeks of age.[107] Compared to wolf and dog pups, golden jackal pups develop aggression at the age of 4–6 weeks, when play-fighting frequently escalates into uninhibited biting intended to harm. This aggression ceases by 10–12 weeks when a hierarchy has formed.[108] Once the lactation period concludes, the female drives off the pups. Pups born late remain with their mother until early autumn, at which time they leave either singly or in groups of two to four individuals. Females reach sexual maturity after 10–11 months and males at 21–22 months.[74]
The golden jackal often hunts alone, and sometimes in pairs, but rarely hunts in apack. When hunting alone, it trots around an area and occasionally stops to sniff and listen. Once prey is located, the jackal conceals itself, quickly approaches its prey and then pounces on it.[103] Single jackals hunt rodents, hares, and birds. They hunt rodents in grass by locating them with their hearing before leaping into the air and pouncing on them. In India, they can digIndian gerbils out from their burrows, and they can hunt young, old, and infirm ungulates up to 4–5 times their body weight. Jackals search for hidingblackbuck calves throughout the day during the calving period. The peak times for their searches are the early morning and the late evening. When hunting in pairs or packs, jackals run parallel to their prey and overtake it in unison. When hunting aquatic rodents or birds, they will run along both sides of narrow rivers or streams and drive their prey from one jackal to another.[103]
Pack-hunting oflangurs is recorded in India. Packs of between 5 and 18 jackals scavenging on the carcasses of large ungulates is recorded in India and Israel.[4] Packs of 8–12 jackals consisting of more than one family have been observed in the summer periods in Transcaucasia.[103] In India, theMontagu's harrier and thePallid harrier roost in their hundreds in grasslands during their winter migration. Jackals stalk close to these roosting harriers and then rush at them, attempting to catch one before the harriers can take off or gain sufficient height to escape.[4]
In Southeastern Asia, golden jackals have been known to hunt alongsidedhole packs.[45] They have been observed in theBlackbuck National Park, Velavadar, India, followingIndian wolves (Canis lupus pallipes) when these are on a hunt, and they will scavenge off wolf kills without any hostility shown from the wolves.[4] In India, lone jackals expelled from their pack have been known to formcommensal relationships withtigers. These solitary jackals, known askol-bahl, will associate themselves with a particular tiger, trailing it at a safe distance to feed on the big cat's kills. Akol-bahl will even alert a tiger to prey with a loud "pheal". Tigers have been known to tolerate these jackals, with one report describing how a jackal confidently walked in and out between three tigers walking together.[109][110] Golden jackals andwild boar can occupy the same territory.[54]
In Europe, there are an estimated 70,000 golden jackals.[77] They are fully protected in Albania, North Macedonia, Germany, Italy, Poland and Switzerland. They are unprotected in Belarus, Bosnia and Herzegovina,[112] Czech Republic, Estonia, and Greece. They are hunted in Bosnia and Herzegovina,[112] Bulgaria, Croatia, Hungary, Kosovo, Latvia, Lithuania, Montenegro, Romania, Serbia, Slovakia, Slovenia, and Ukraine. Their protection in Austria and Turkey depends on the part of the country. Their status in Moldova is not known.[76]
The Syrian jackal was common in Israel and Lebanon in the 1930s–40s, but their populations were reduced during an anti-rabies campaign. Its current status is difficult to ascertain, due to possiblehybridisation with pariah dogs andAfrican golden wolves.[16][61] The jackal population for the Indian subcontinent is estimated to be over 80,000.[1] In India, the golden jackal occurs in all of India's protected areas apart from those in the higher areas of the Himalayas. It is included inCITES AppendixIII, and is listed in theWildlife Protection Act, 1972, under ScheduleIII, thus receiving legal protection at the lowest level to help control the trade of pelts and tails in India.[1]
Golden jackals appear inIndian folklore and in two ancient texts, theJakatas and thePanchatantra, where they are portrayed as intelligent and wily creatures.[4] The ancient Hindu text, theMahabharata, tells the story of a learned jackal who sets his friends the tiger, wolf,mongoose, and mouse against each other so he can eat a gazelle without sharing it. ThePanchatantra tells the fable of a jackal who cheats a wolf and a lion out of their shares of a camel.[113] InBuddhist tales, the jackal is regarded as being cunning in a way similar to the fox in European tales.[114] One popular Indian saying describes the jackal as "the sharpest among beasts, the crow among birds, and the barber among men". For a person embarking on an early morning journey, hearing a jackal howl was considered to be a sign of impending good fortune, as was seeing a jackal crossing a road from the left side.[115]
InHinduism, the jackal is portrayed as the familiar of several deities with the most common beingChamunda, the emaciated, devouring goddess of the cremation grounds. Another deity associated with jackals isKali, who inhabits the cremation ground and is surrounded by millions of jackals. According to theTantrasara scripture, when offered animal flesh, Kali appears in the form of a jackal. The goddessShivaduti is depicted with a jackal's head.[114] The goddessDurga was often linked to the jackal. Jackals are considered to be thevahanas (vehicles) of various protective Hindu and Buddhist deities, particularly in Tibet.[116] According to theflood myth of the Kamar people inRaipur district, India, the god Mahadeo (Shiva) caused a deluge to dispose of a jackal who had offended him.[117] InRudyard Kipling'sMowgli stories collected inThe Jungle Book, the characterTabaqui is a jackal despised by the Seeonee wolf pack due to his mock cordiality, his scavenging habits, and his subservience toShere Khan the tiger.[118]
In the Marwahi forest division of theChhattisgarh state in eastern India, the jackal is of conservation value and there were no jackal attacks reported before 1997. During 1998–2005 there were 220 reported cases of jackal attacks on humans, although none were fatal. The majority of these attacks occurred in villages, followed by forests and crop fields. Jackals build their dens in the bouldery hillocks that surround flat areas, and these areas have been encroached by human agriculture and settlements. This encroachment has led tohabitat fragmentation and the need for jackals to enter agricultural areas and villages in search for food, resulting in conflict with humans. People in this region habitually chase jackals from their villages, which leads to the jackals becoming aggressive. Female jackals with pups respond with an attack more often than lone males. In comparison, over twice as many attacks were carried out bysloth bears over the same period.[119] There are no known attacks on humans in Europe.[31]
The golden jackal can be a harmful pest that attacks domestic animals such asturkeys, lambs,sheep,goats,domestic water buffalo calves, and valuable game species like newbornroe deer,hares,coypu,pheasants,francolins,grey partridges,bustards andwaterfowl.[120] It destroys grape, coffee, maize, sugarcane,[4] and eatswatermelons,muskmelons, andnuts.[120] In Greece, golden jackals are not as damaging to livestock as wolves and red foxes but they can become a serious nuisance to small stock when in great numbers. In southern Bulgaria, over 1,000 attacks on sheep and lambs were recorded between 1982 and 1987, along with some damage to newborn deer in game farms. The damage by jackals in Bulgaria was minimal when compared to the livestock losses due to wolves.[54] Approximately 1.5–1.9% of calves born in theGolan Heights die due to predation, mainly by jackals.[121] The high predation rate by jackals in both Bulgaria and Israel is attributable to the lack of preventative measures in those countries and the availability of food in illegal garbage dumps, leading to jackal population explosions.[54]
Golden jackals are extremely harmful to fur-bearing rodents, such as coypu andmuskrats. Coypu can be completely extirpated in shallow water bodies. During 1948–1949 in theAmu Darya, muskrats constituted 12.3% of jackal fecal contents, and 71% of muskrat houses were destroyed by jackals. Jackals also harm the fur industry by eating muskrats caught in traps or taking skins left out to dry.[120]
During British rule inIndia, sportsmen conducted golden jackal hunting on horseback with hounds, withjackal coursing a substitute for thefox hunting of their native England. They were not considered as beautiful as English red foxes, but were esteemed for their endurance in the chase with one pursuit lasting3+1⁄2 hours. India's weather and terrain added further challenges to jackal hunters that were not present in England: the hounds of India were rarely in as good condition as English hounds, and although the golden jackal has a strong odor, the terrain of northern India was not good in retaining scent.[122] Also, unlike foxes, jackals sometimesfeigned death when caught and could be ferociously protective of their captured packmates.[71]
Jackals were hunted in three ways: withgreyhounds, withfoxhounds, and with mixed packs. Hunting jackals with greyhounds offered poor sport because greyhounds were too fast for jackals, and mixed packs were too difficult to control.[122] From 1946 inIraq, British diplomats and Iraqi riders conducted jackal coursing together. They distinguished three types of jackal: the "city scavenger", which was described as being slow and so smelly that dogs did not like to follow them; the "village jack", which was described as being faster, more alert, and less odorous; and the "open-country jack", which was described as being the fastest, cleanest, and providing the best sport of all three populations.[123]
Some indigenous people of India, such as theKolis and Vaghirs ofGujarat andRajasthan and theNarikuravas inTamil Nadu, hunt and eat golden jackals, but the majority of South Asian cultures consider the animal to be unclean. The orthodoxdharma texts forbid the eating of jackals because they have five nails.[114] In the area of theformer Soviet Union, jackals are not actively hunted and are usually captured only incidentally during the hunting of other animals by means of traps or shooting during drives. In Transcaucasia, jackals are captured with large fishing hooks baited with meat and suspended 75–100 cm (30–39 in) from the ground with wire. The jackals can only reach the meat by jumping, and are then hooked by the lip or jaw.[120]
In Russia and the other nations of the former Soviet Union, golden jackals are considered furbearers of low quality because of their sparse, coarse, and monotonously colored fur.[120] Jackal hairs have very little fur fiber; therefore, their pelts have a flat appearance. The jackals of Asia and the Middle East produce the coarsest pelts, though this can be remedied during thedressing process.Elburz in northern Iran produces the softest furs.[124] Jackal skins are not graded to a fur standard, and are made into collars, women's coats, and fur coats. During the 1880s, 200 jackals were captured annually in Mervsk and in the Zakatal area of the Transcaucasus, with 300 jackals being captured there during 1896. In this same period, a total of 10,000 jackals were taken within Russia and their furs sent exclusively to theNizhegorod fair. In the early 1930s there were 20,000–25,000 jackal skins tanned annually in the Soviet Union, but these could not be utilized within the country, and so the majority were exported to the United States. Commencing from 1949, they were all used within the Soviet Union.[120]
The golden jackal may have once been tamed in NeolithicTurkey 11,000 years ago, as there is a sculpture of a man cradling a jackal found inGöbekli Tepe.[125] French explorers during the 19thcentury noted that people in theLevant kept golden jackals in their homes.[126] TheKalmyk people near the Caspian Sea were known to frequently cross their dogs with jackals,[126] and Balkan shepherds once crossed their sheepdogs with jackals.[24]
The Russian military established the Red Star kennels in 1924 to improve the performance of working dogs and to conduct military dog research. The Red Star kennel developed "Laikoid" dogs, which were a cross-breed ofSpitz-type RussianLaikas withGerman Shepherds. By the 1980s, the ability of Russia's bomb and narcotic detection dogs were assessed as being inadequate. Klim Sulimov, a research scientist with the DS Likhachev Scientific Research Institute for Cultural Heritage and Environmental Protection, began cross-breeding dogs with their wild relatives in an attempt to improve their scent-detection abilities. The researchers assumed that during domestication dogs had lost some of their scent-detection ability because they no longer had to detect prey. Sulimov crossed European jackals with Laikas, and also withfox terriers to add trainability and loyalty to the mix. He used the jackal because he believed that it was the wild ancestor of the dog, that it had superior scent-detecting ability, and, because it was smaller with more endurance than the dog, it could be housed outdoors in the Russian climate. Sulimov favored a mix of one quarter jackal and three-quarters dog. Sulimov's program continues today with the use of the hybridSulimov dogs at theSheremetyevo Airport nearMoscow by the Russian airlineAeroflot.[127]
The hybrid program has been criticized, with one of Sulimov's colleagues pointing out that in other tests the Laika performed just as well as the jackal hybrids. The assumption that dogs have lost some of their scent-detection ability may be incorrect, in that dogs need to be able to scent-detect and identify the many humans that they come into contact with in their domesticated environment. Another researcher crossed German Shepherds with wolves and claimed that this hybrid had superior scent-detection abilities. The scientific evidence to support the claims of hybrid researchers is minimal, and more research has been called for.[127]
