|Present and historical distribution of the leopard|
The leopard (Panthera pardus) is one of the five extant species in the genus Panthera, a member of the Felidae. It occurs in a wide range in sub-Saharan Africa, in some parts of Western and Central Asia, Southern Russia, and on the Indian subcontinent to Southeast and East Asia. It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. The leopard is considered locally extinct in Hong Kong, Singapore, South Korea, Jordan, Morocco, Togo, the United Arab Emirates, Uzbekistan, Lebanon, Mauritania, Kuwait, Syria, Libya, Tunisia and most likely in North Korea, Gambia, Laos, Lesotho, Tajikistan, Vietnam and Israel. Contemporary records suggest that the leopard occurs in only 25% of its historical global range.
Compared to other wild cats, the leopard has relatively short legs and a long body with a large skull. Its fur is marked with rosettes. It is similar in appearance to the jaguar (Panthera onca), but has a smaller, lighter physique, and its rosettes are generally smaller, more densely packed and without central spots. Both leopards and jaguars that are melanistic are known as black panthers. The leopard is distinguished by its well-camouflaged fur, opportunistic hunting behaviour, broad diet, strength, and its ability to adapt to a variety of habitats ranging from rainforest to steppe, including arid and montane areas. It can run at speeds of up to 58 km/h (36 mph). The earliest known leopard fossils excavated in Europe are estimated 600,000 years old, dating to the late Early Pleistocene. Leopard fossils were also found in Japan and Sumatra.
The English name 'leopard' comes from Old French: leupart or Middle French: liepart, that derives from Latin: leopardus and Ancient Greek: λέοπάρδος (leopardos). Leopardos could be a compound of λέων (leōn), meaning lion, and πάρδος (pardos). The word λέοπάρδος originally referred to a cheetah (Acinonyx jubatus).
'Panther' is another common name, derived from Latin: panther and Ancient Greek: πάνθηρ (pánthēr); The generic name Panthera originates in Latin: panthera, which refers to a hunting net for catching wild beasts that were used by the Romans in combats. The phonetically similar Sanskrit: पाण्डर (pând-ara) means pale yellow, whitish or white. The specific name Latin: pardus refers to a male panther. The word pardus is thought to originate from Ancient Greek: παρδάλωτός (pardalotόs) meaning spotted like a leopard.
The leopard's fur is generally soft and thick, notably softer on the belly than on the back. Its skin colour varies between individuals from pale yellowish to dark golden with dark spots grouped in rosettes. Its belly is whitish and its ringed tail is shorter than its body. Its pupils are round. Leopards living in arid regions are pale cream, yellowish to ochraceous and rufous in colour; those living in forests and mountains are much darker and deep golden. Spots fade toward the white underbelly and the insides and lower parts of the legs. Rosettes are circular in East African leopard populations, and tend to be squarish in Southern African and larger in Asian leopard populations. The fur tends to be grayish in colder climates, and dark golden in rain forest habitats. The pattern of the rosettes is unique in each individual.
Its fur tends to grow longer in colder climates. The guard hairs protecting the basal hairs are short, 3–4 mm (0.1–0.2 in) in face and head, and increase in length toward the flanks and the belly to about 25–30 mm (1.0–1.2 in). Juveniles have woolly fur, and appear to be dark-coloured due to the densely arranged spots. Its white-tipped tail is about 60–100 cm (23.6–39.4 in) long, white underneath and with spots that form incomplete bands toward the tail's end. The leopard's rosettes differ from those of the jaguar (Panthera onca), which are darker and with smaller spots inside. The cheetah has small round spots without any rosettes.
The largest skull of a leopard was recorded in India in 1920 and measured 28 cm (11.0 in) in basal length, 20 cm (7.9 in) in breadth, and weighed 1,000 g (2 lb 4 oz). The skull of a West African leopard measured 285.8 mm (11.25 in) in basal length, and 181.0 mm (7.125 in) in breadth, and weighed 790 g (1 lb 12 oz).
Size and weight
The leopard is sexually dimorphic with males larger and heavier than females. It is muscular, with relatively short limbs and a broad head. Males stand 60–70 cm (23.6–27.6 in) at the shoulder, while females are 57–64 cm (22.4–25.2 in) tall. The head-and-body length ranges between 90 and 196 cm (2 ft 11.4 in and 6 ft 5.2 in) with a 66 to 102 cm (2 ft 2.0 in to 3 ft 4.2 in) long tail. Sizes vary geographically. Males weigh 37–90 kg (81.6–198.4 lb), and females 28–60 kg (61.7–132.3 lb). Some leopards in North Africa allegedly were as large as Barbary lions (Panthera leo leo). In 1913, an Algerian newspaper reported a leopard killed that allegedly measured about 275 cm (9 ft 0 in) in total length. The maximum weight of a wild leopard in Southern Africa was about 96 kg (212 lb). It measured 262 cm (8 ft 7.1 in). An Indian leopard killed in Himachal Pradesh in 2016 measured 261 cm (8 ft 6.8 in) with an estimated weight of 78.5 kg (173.1 lb); it was perhaps the largest known wild leopard.
Melanistic leopards are also called black panthers. Melanism in leopards is inherited as a recessive trait relatively to the spotted form. Interbreeding in melanistic leopards produces a significantly smaller litter size than is produced by normal pairings. The black leopard is common foremost in tropical and subtropical moist forests like the equatorial rainforest of the Malay Peninsula and the tropical rainforest on the slopes of some African mountains such as Mount Kenya. Between January 1996 and March 2009, leopards were photographed at 16 sites in the Malay Peninsula in a sampling effort of more than 1,000 camera trap nights. Of the 445 photographs of melanistic leopards, 410 were taken in study sites south of the Kra Isthmus, where the non-melanistic morph was never photographed. These data indicate the near-fixation of the dark allele in the region. The expected time for the fixation of this recessive allele due to genetic drift alone ranged from about 1,100 years to about 100,000 years. Pseudomelanistic leopards have also been reported.
In India, nine pale and white leopards were reported between 1905 and 1967. Leopards exhibiting erythrism were recorded between 1990 and 2015 in South Africa's Madikwe Game Reserve and in Mpumalanga. The cause of this morph, known as a "strawberry leopard" or "pink panther", is not well understood.
Felis pardus was the scientific name proposed by Carl Linnaeus in 1758. The generic name Panthera was first used by Lorenz Oken in 1816, who included all the known spotted cats into this group. Oken's classification was not widely accepted, and Felis or Leopardus was used as the generic name until the early 20th century.
The leopard was determined as the type species of Panthera by Joel Asaph Allen in 1902. In 1917, Reginald Innes Pocock also subordinated the tiger (P. tigris), lion (P. leo), and jaguar (P. onca) to Panthera.
Following Linnaeus' first description, 27 leopard subspecies were proposed by naturalists between 1794 and 1956. Since 1996, only eight subspecies have been considered valid on the basis of mitochondrial analysis. Later analysis revealed a ninth valid subspecies, the Arabian leopard.
In 2017, the Cat Classification Task Force of the Cat Specialist Group recognized the following eight subspecies as valid taxa:
|African leopard (P. p. pardus) (Linnaeus, 1758)||It is the most widespread leopard subspecies and is native to most of Sub-Saharan Africa.|
|Indian leopard (P. p. fusca) (Meyer, 1794)||It is native to the Indian subcontinent, as well as Myanmar and southern Tibet.|
|Javan leopard (P. p. melas) (Cuvier, 1809)||It is native to Java in Indonesia and is considered Critically Endangered.|
|Arabian leopard (P. p. nimr) (Hemprich and Ehrenberg, 1830)||It is native to the Arabian Peninsula, but considered locally extinct in the Sinai Peninsula. It is the smallest leopard subspecies.|
|P. p. tulliana (Valenciennes, 1856)||It is native to eastern Turkey, the Caucasus, southern Russia, and the Iranian Plateau to the Hindu Kush. It is considered Endangered.|
|Amur leopard (P. p. orientalis) (Schlegel, 1857)||It is native to the Russian Far East and northern China, but is locally extinct in the Korean peninsula.|
|Indochinese leopard (P. p. delacouri) Pocock, 1930||It is native to mainland Southeast Asia and southern China.|
|Sri Lankan leopard (P. p. kotiya) Deraniyagala, 1956||It is native to Sri Lanka.|
Results of an analysis of molecular variance and pairwise fixation index of 182 African leopard museum specimens published in 2017 showed that some African leopards exhibit higher genetic differences than certain Asian leopards which are recognized as subspecies.
Results of phylogenetic studies based on nDNA and mtDNA analysis showed that the last common ancestor of the Panthera and Neofelis genera is thought to have lived about . Neofelis diverged about from the Panthera lineage. The tiger diverged about , followed by the snow leopard about and the leopard about . The leopard is a sister taxon to a clade within Panthera, consisting of the lion and the jaguar. The geographic origin of the Panthera is most likely northern Central Asia. The leopard-lion clade was distributed in the Asian and African Palearctic since at least the early Pliocene. The leopard-lion clade diverged 3.1–1.95 million years ago. Additionally, a 2016 study revealed that the mitochondrial genomes of the leopard, lion and snow leopard are more similar to each other than their nuclear genomes, indicating that their ancestors hybridized with the snow leopard at some point in their evolution.
Fossils of leopard ancestors were excavated in East Africa and South Asia, dating back to the Pleistocene between 2 and . The modern leopard is suggested to have evolved in Africa about and to have radiated across Asia about 0.2 and . Fossil cat teeth collected in Sumatra's Padang Highlands were assigned to the leopard. It has since been hypothesized that it became extirpated from the island due to the Toba eruption about 75,000 years ago, and due to competition with other predators, such as the Sunda clouded leopard (Neofelis diardi) and the dhole (Cuon alpinus).
In Europe, the leopard occurred at least since the Pleistocene. Leopard-like fossil bones and teeth possibly dating to the Pliocene were excavated in Perrier in France, northeast of London, and in Valdarno, Italy. Until 1940, similar fossils dating back to the Pleistocene were excavated mostly in loess and caves at 40 sites in Europe, including Furninha Cave near Lisbon, Genista Caves in Gibraltar, and Santander Province in northern Spain to several sites across France, Switzerland, Italy, Austria, Germany, in the north up to Derby in England, in the east to Přerov in the Czech Republic and the Baranya in southern Hungary, Leopard fossils dating to the Late Pleistocene were found in Biśnik Cave in south-central Poland. The oldest known leopard fossils excavated in Europe are about 600,000 years old and were found in the Grotte du Vallonnet in France and near Mauer in Germany. Four European Pleistocene leopard subspecies were proposed. P. p. begoueni from the beginning of the Early Pleistocene was replaced about by P. p. sickenbergi, which in turn was replaced by P. p. antiqua around 0.3 million years ago. The most recent, P. p. spelaea, appeared at the beginning of the Late Pleistocene and survived until about 24,000 years ago in several parts of Europe. Leopard fossils dating to the Pleistocene were also excavated in the Japanese archipelago.
The leopard was crossbred with other Panthera species and cougars (Puma concolor) in zoos. In 1953, a lioness and a male leopard were mated in Hanshin Park in Nishinomiya, Japan. The first litter from this pair was born in November 1959, consisting of a male and a female. Another litter was born in 1961, in which all the offspring were spotted and bigger than a juvenile leopard. This hybrid came to be known as a leopon. Unsuccessful attempts were made to mate a leopon with a tigress.
Distribution and habitat
The leopard has the largest distribution of all wild cats, occurring widely in Africa as well as the Caucasus and Asia, although populations are fragmented and declining. It is considered to be extirpated in North Africa. It inhabits foremost savanna and rainforest, and areas where grasslands, woodlands, and riverine forests remain largely undisturbed. In sub-Saharan Africa, it is still numerous and surviving in marginal habitats where other large cats have disappeared. There is considerable potential for human-leopard conflict due to leopards preying on livestock.
Leopard populations on the Arabian Peninsula are small and fragmented. In southeastern Egypt, a leopard killed in 2017 was the first record in this area in 65 years. In western and central Asia, it avoids deserts, areas with long snow cover and proximity to urban centres.
In Nepal's Kanchenjunga Conservation Area, a melanistic leopard was photographed at an elevation of 4,300 m (14,100 ft) by a camera trap in May 2012. In the Indian subcontinent, the leopard is still relatively abundant, with greater numbers than those of other Panthera species. As of 2020, the leopard population within forested habitats in India's tiger range landscapes was estimated at 12,172 to 13,535 individuals. Surveyed landscapes included elevations below 2,600 m (8,500 ft) in the Shivalik Hills and Gangetic plains, Central India and Eastern Ghats, Western Ghats, as well as the Brahmaputra River basin and hills in Northeast India. Some leopard populations in the country live quite close to human settlements and even in semi-developed areas. Although adaptable to human disturbances, leopards require healthy prey populations and appropriate vegetative cover for hunting for prolonged survival and thus rarely linger in heavily developed areas. Due to the leopard's stealth, people often remain unaware that they live in nearby areas.
In Myanmar, leopards were recorded for the first time by camera traps in the hill forests of Myanmar's Karen State. The Northern Tenasserim Forest Complex in southern Myanmar is considered a leopard stronghold. In Thailand, leopards are present in the Western Forest Complex, Kaeng Krachan-Kui Buri, Khlong Saeng-Khao Sok protected area complexes and in Hala Bala Wildlife Sanctuary bordering Malaysia. In Peninsular Malaysia, leopards are present in Belum-Temengor, Taman Negara and Endau-Rompin National Parks. In Laos, leopards were recorded in Nam Et-Phou Louey National Biodiversity Conservation Area and Nam Kan National Protected Area. In Cambodia, leopards inhabit deciduous dipterocarp forest in Phnom Prich Wildlife Sanctuary and Mondulkiri Protected Forest. In southern China, leopards were recorded only in the Qinling Mountains during surveys in 11 nature reserves between 2002 and 2009.
In Java, leopards inhabit dense tropical rainforests and dry deciduous forests at altitudes from sea level to 2,540 m (8,330 ft). Outside protected areas, leopards were recorded in mixed agricultural land, secondary forest and production forest between 2008 and 2014.
Behaviour and ecology
The leopard is a solitary and territorial animal. Adults associate only in the mating season. Females continue to interact with their offspring even after weaning, and have been observed sharing kills with their offspring when they can not obtain any prey. They produce a number of vocalizations, including growls, snarls, meows and purrs. The roaring sequence in leopards consists mainly of grunts and is also called "sawing", having been described as resembling the sound of sawing wood. Cubs are known to call their mother with a urr-urr sound.
The whitish spots on the back of its ears are thought to play a role in communication. It has been hypothesized that the white tips of their tails may function as a 'follow-me' signal in intraspecific communication. However, no significant association were found between a conspicuous colour of tail patches and behavioural variables in carnivores.
Leopards are active mainly from dusk till dawn and rest for most of the day and for some hours at night in thickets, among rocks or over tree branches. Leopards have been observed walking 1–25 km (1⁄2–15+1⁄2 mi) across their range at night; they may even wander up to 75 km (47 mi) if disturbed. In some regions, they are nocturnal. In western African forests, they have been observed to be largely diurnal and hunting during twilight, when their prey animals are active; activity patterns varies between seasons.
Leopards can climb trees very skillfully, often rest on tree branches and descend from trees headfirst. They can run at over 58 km/h (36 mph), leap over 6 m (20 ft) horizontally, and jump up to 3 m (10 ft) vertically.
In Kruger National Park, most leopards tend to keep 1 km (1⁄2 mi) apart. Males interact with their partners and cubs at times, and exceptionally this can extend beyond to two generations. Aggressive encounters are rare, typically limited to defending territories from intruders. In a South African reserve, a male was wounded in a male–male territorial battle over a carcass.
Males occupy territories that often overlap with a few smaller female territories, probably as a strategy to enhance access to females. In the Ivory Coast, the home range of a female was completely enclosed within a male's. Females live with their cubs in territories that overlap extensively, probably due to the association between mothers and their offspring. There may be a few other fluctuating territories, belonging to young individuals. It is not clear if male territories overlap as much as those of females do. Individuals try to drive away intruders of the same sex.
A study of leopards in the Namibian farmlands showed that the size of territories was not significantly affected by sex, rainfall patterns or season; it concluded that the higher the prey availability in an area, the greater the population density of leopards and the smaller the size of territories, but territories tend to expand if there is human interference (which has been notably high in the study area). Territorial sizes vary geographically and depending on habitat and availability of prey. In the Serengeti, they are as small as 33–38 km2 (12+1⁄2–14+1⁄2 sq mi) for males and 14–16 km2 (5+1⁄2–6 sq mi) for females, and as large as 451 km2 (174 sq mi) for males and 188 km2 (72+1⁄2 sq mi) for females in northeastern Namibia. They are even larger in arid and montane areas. Territories recorded in Nepal's Bardia National Park, 48 km2 (18+1⁄2 sq mi) for males and 5–7 km2 (2–2+1⁄2 sq mi) for females, are smaller than those generally observed in Africa.
Hunting and diet
The leopard depends mainly on its acute senses of hearing and vision for hunting. It primarily hunts at night in most areas. In western African forests and Tsavo National Park, leopards have been also observed hunting by day. Leopards usually hunt on the ground. In the Serengeti, leopards have been observed to ambush prey by jumping down on it from trees.
The leopard is a carnivore that prefers medium-sized prey with a body mass ranging from 10–40 kg (22–88 lb). Prey species in this weight range tend to occur in dense habitat and to form small herds. Species that prefer open areas and developed significant anti-predator strategies are less preferred. More than 100 prey species were recorded. The most significantly preferred species are ungulates; impala (Aepyceros melampus), bushbuck (Tragelaphus scriptus), common duiker (Sylvicapra grimmia) and chital (Axis axis). Primate species preyed upon include those of the genera Cercocebus, Cercopithecus and Semnopithecus. Analysis of leopard scat in Taï National Park revealed that primates, except for chimpanzee (Pan troglodytes) and potto (Perodicticus potto), are primary leopard prey during the day. Leopards also kill smaller carnivores like black-backed jackal, bat-eared fox, genet and cheetah.
Prey as heavy as a 550 kg (1,210 lb) giraffe is hunted, especially in areas that lack larger carnivores such as lions or tigers since they do not need to drag prey up trees to retain it. In areas such as Sri Lanka, reserves in Central Asia and the Middle East and most of the montane and tropical rainforests of Africa, the leopard is the remaining top terrestrial predator present and often take varied prey of various sizes, including at times large ungulates weighing hundreds of kilograms, although they also takes smaller prey such as monkeys where ungulates are scarce. A study in Wolong National Nature Reserve in southern China demonstrated variation in the leopard's diet over time; over the course of seven years, the vegetative cover receded, and leopards opportunistically shifted from primarily consuming tufted deer to pursuing bamboo rats and other smaller prey. The largest prey killed by a leopard was reportedly a male eland weighing 900 kg (2,000 lb).
Average daily consumption rates of 3.5 kg (7 lb 11 oz) were estimated for males and of 2.8 kg (6 lb 3 oz) for females. A study in the southern Kalahari Desert showed that leopards meet their water requirements by the bodily fluids of prey and succulent plants; they drink water every two to three days, and feed infrequently on moisture-rich plants such as gemsbok cucumbers (Acanthosicyos naudinianus), tsamma melon (Citrullus lanatus) and Kalahari sour grass (Schmidtia kalahariensis).
The leopard stalks its prey and tries to approach as close as possible, typically within 5 m (16 ft) to the target, and finally pounces on it and kills it by suffocation. It kills small prey with a bite on the back of the neck, but holds larger animals by the throat and strangles them. It is able to take large prey due to its massive skull and powerful jaw muscles, and is therefore strong enough to drag carcasses heavier than itself up into trees; an individual was seen to haul a young giraffe, weighing nearly 125 kg (276 lb), up 5.7 m (18 ft 8 in) into a tree. Kills are cached up to 2 km (1+1⁄4 mi) apart. Small prey is eaten immediately, while larger carcasses are dragged over several hundred metres and safely cached in trees, bushes or even caves to be consumed later. The way the kill is stored depends on local topography and individual preferences; while trees are preferred in Kruger National Park, bushes are preferred in the plain terrain of the Kalahari.
Enemies and competitors
In parts of its global range, the leopard is sympatric with other large predators such as the tiger (Panthera tigris), lion (P. leo), cheetah, spotted hyena (Crocuta crocuta), striped hyena (Hyaena hyaena), brown hyena (H. brunnea), African wild dog (Lycaon pictus), dhole (Cuon alpinus), wolf (Canis lupus) and up to five bear species. Some of these species steal its kills, kill its cubs and even kill adult leopards. Leopards retreat up a tree in the face of direct aggression, and were observed when killing or preying on smaller competitors such as black-backed jackal, African civet (Civettictis civetta), caracal (Caracal caracal) and African wildcat (Felis lybica). Leopards generally seem to avoid encounters with adult bears, but kill vulnerable bear cubs. In Sri Lanka, a few recorded vicious fights between leopards and sloth bears (Melursus ursinus) apparently result in both animals winding up either dead or grievously injured.
While interspecies killing of full-grown leopards is generally rare, given the opportunity, both tiger and lion readily kill and consume both young and adult leopards. In the Kalahari Desert, leopards frequently lose kills to brown hyenas, if the leopard is unable to move the kill into a tree. Single brown hyenas have been observed charging at and displacing male leopards from kills. Lions occasionally fetch leopard kills from trees.
Resource partitioning occurs where leopards share their range with tigers. Leopards tend to take smaller prey, usually less than 75 kg (165 lb), where tigers are present. In areas where leopard and tiger are sympatric, coexistence is reportedly not the general rule, with leopards being few where tigers are numerous. The mean leopard density decreased significantly (from 9.76 to 2.07 animals per 100 km2 (39 sq mi)) while the mean density of tigers increased (from 3.31 to 5.81 animals/100 km2) from 2004–2005 to 2008 in Rajaji National Park following the relocation of pastoralists out of the park. There, the two species have high dietary overlap, and an increase in the tiger population resulted in a sharp decrease in the leopard population and a shift in the leopard diet to small prey (from 9% to 36%) and domestic prey (from 6.8% to 31.8%). In Chitwan National Park, leopards killed prey ranging from less than 25–100 kg (55–220 lb) in weight with most kills in the 25–50 kg (55–110 lb) range. Tigers killed more prey in the 50–100 kg (110–220 lb) range. There were also differences in the microhabitat preferences of the individual tiger and leopard followed over five months; the tiger used roads and forested areas more frequently, while the leopard used recently burned areas and open areas more frequently. When a tiger killed baits at sites formerly frequented by leopards, the leopards did not hunt there for some time. In the tropical forests of India's Nagarhole National Park, tigers selected prey weighing more than 176 kg (388 lb), whereas leopards selected prey in the 30–175 kg (66–386 lb) range. In tropical forests, they do not always avoid the larger cats by hunting at different times. With relatively abundant prey and differences in the size of prey selected, tigers and leopards seem to successfully coexist without competitive exclusion or interspecies dominance hierarchies that may be more common to the leopard's co-existence with the lion in savanna habitats. In areas with high tiger populations, such as in the central parts of India's Kanha National Park, leopards are not permanent residents, but transients. They were common near villages at the periphery of the park and outside the park. In a reserved forest of southern India, species preyed upon by leopard, dhole and striped hyena overlapped considerably. In the mid-20th century, the Amur leopard was absent or very rarely encountered in the Primorye region of the Russian Far East in areas where the Siberian tiger (P. tigris tigris) was recorded. Surveys conducted at the beginning of the 21st century revealed that the ranges of both species overlap in this region, especially in protected areas where ungulate densities are high and human disturbance is low.
Nile crocodiles (Crocodylus niloticus) prey on leopards occasionally. One large adult leopard was grabbed and consumed by a large crocodile while attempting to hunt along a bank in Kruger National Park. Mugger crocodiles (Crocodylus palustris) reportedly killed an adult leopard in Rajasthan. An adult leopard was recovered from the stomach of a 5.5 m (18 ft 1 in) Burmese python (Python bivittatus).
Reproduction and life cycle
Depending on the region, leopards may mate all year round. In Manchuria and Siberia, they mate during January and February. The estrous cycle lasts about 46 days and the female usually is in heat for 6–7 days. Gestation lasts for 90 to 105 days. Cubs are usually born in a litter of 2–4 cubs. Mortality of cubs is estimated at 41–50% during the first year.
Females give birth in a cave, crevice among boulders, hollow tree, or thicket to make a den. Cubs are born with closed eyes, which open four to nine days after birth. The fur of the young tends to be longer and thicker than that of adults. Their pelage is also more gray in colour with less defined spots. Around three months of age, the young begin to follow the mother on hunts. At one year of age, leopard young can probably fend for themselves, but remain with the mother for 18–24 months.
The average typical life span of a leopard is between 12 and 17 years. The oldest recorded spotted leopard was a female named Roxanne living in captivity at McCarthy's Wildlife Sanctuary in The Acreage, Palm Beach County, Florida. She died August 8, 2014 at the age of 24 years, 2 months and 13 days. This has been verified by the Guinness Book of World Records. Previously, the oldest recorded leopard was a female named Bertie living in captivity in the Warsaw Zoo. She died in December 2010 at the age of 24. The oldest recorded male leopard was Cezar, who reached the age of 23. He also lived at the Warsaw Zoo and was Bertie's lifelong companion. The generation length of the leopard is 9.3 years.
The leopard is primarily threatened by habitat fragmentation and conversion of forest to agriculturally used land, which lead to a declining natural prey base, human–wildlife conflict with livestock herders and high leopard mortality rates. It is also threatened by trophy hunting and poaching.
Between 2002 and 2012, at least four leopards were estimated to have been poached per week in India for the illegal wildlife trade of its skins and bones. In spring 2013, 37 leopard skins were found during a 7-week long market survey in major Moroccan cities. In 2014, 43 leopard skins were detected during two surveys in Morocco. Vendors admitted to have imported skins from sub-Saharan Africa.
Surveys in the Central African Republic's Chinko area revealed that the leopard population decreased from 97 individuals in 2012 to 50 individuals in 2017. In this period, transhumant pastoralists from the border area with Sudan moved in the area with their livestock. Rangers confiscated large amounts of poison in the camps of livestock herders who were accompanied by armed merchants. They engaged in poaching large herbivores, sale of bushmeat and trading leopard skins in Am Dafok.
Leopards have been known to humans throughout history, and have featured in the art, mythology, and folklore of many countries where they have historically occurred. In Greek mythology, the leopard was a symbol of the god Dionysus; who was depicted wearing leopard skin and using leopards as means of transportation. In one myth, the god was captured by pirates but two leopards appear and rescue him. The Ancient Romans kept leopards in captivity to be slaughtered in hunts as well as be used in executions of criminals. During the Benin Empire, the leopard was commonly represented on engravings and sculptures and was used to symbolize the power of the king or oba, since the leopard was considered the king of the forest. Leopards were also kept and paraded as mascots, totems and sacrifices to deities.
The lion passant guardant or leopard is a frequently used charge in heraldry, most commonly appearing in groups of three. The heraldic leopard lacks spots and sports a mane, making it visually almost identical to the heraldic lion, and the two are often used interchangeably. These traditional lions passant guardant appear in the coat of arms of Dalmatia and the coat of arms of England and many of its former colonies; more modern naturalistic (leopard-like) depictions appear on the coat of arms of several African nations including Benin, Malawi, Somalia, the Democratic Republic of the Congo and Gabon, the last of which uses a black panther. Coats made of leopard skins were worn by African chiefs, European queens, Hollywood actors and burlesque dancers.
Leopard captivity in historical times has also been recorded — several leopards were kept in a menagerie established by King John at the Tower of London in the 13th century; around 1235, three of these animals were given to Henry III by Holy Roman Emperor Frederick II.
Most leopards avoid people, but humans may occasionally be targeted as prey. Most healthy leopards prefer wild prey to humans, but injured, sickly, or struggling cats, or those with a shortage of regular prey, may resort to hunting humans and become habituated to it. Although usually slightly smaller than a human, an adult leopard is much more powerful and easily capable of killing one. Two extreme cases occurred in India: the first leopard, "the Leopard of Rudraprayag", killed more than 125 people; the second, "the Panar Leopard", was believed to have killed more than 400. Both were killed by the renowned hunter and conservationist Jim Corbett. Man-eating leopards are considered bold and difficult to track and may enter human settlements for prey, more so than lions and tigers. Author and big game hunter, Kenneth Anderson, had first-hand experience with many man-eating leopards, and described them as far more threatening than tigers:
Although examples of such animals are comparatively rare, when they do occur they depict the panther [leopard] as an engine of destruction quite equal to his far larger cousin, the tiger. Because of his smaller size he can conceal himself in places impossible to a tiger, his need for water is far less, and in veritable demoniac cunning and daring, coupled with the uncanny sense of self-preservation and stealthy disappearance when danger threatens, he has no equal.— Kenneth Anderson, Nine Man-Eaters and One Rogue, Chapter II "The Spotted Devil of Gummalapur"
There is something very terrifying in the angry grunt of a charging leopard, and I have seen a line of elephants that were staunch to a tiger, turn and stampede from a charging leopard.— Jim Corbett, The Temple Tiger and More Man-Eaters of Kumaon, chapter "The Panar Man-Eater"
