Leopard

The leopard (''Panthera pardus'') is one of the five extant species in the genus ''Panthera''. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular reaching a length of with a long tail and a shoulder height of . Males typically weigh , and females .

The leopard was first described in 1758, and several subspecies were proposed in the 19th and 20th centuries. Today, eight subspecies are recognised in its wide range in Africa and Asia. It probably evolved in Africa about and radiated across Asia about 0.2 and . Fossil leopard bones were excavated at 40 sites in Europe, where it had occurred at least since the Pleistocene, but survived until about 24,000 years ago.

It is adapted to a variety of habitats ranging from rainforest to steppe, including arid and montane areas. It is an opportunistic predator, hunting mostly ungulates and primates. It relies on its spotted pattern for camouflage as it stalks and ambushes its prey, which it sometimes drags up a tree. It is a solitary animal outside the mating season and when raising cubs. Females usually give birth to a litter of 2–4 cubs once in 15–24 months. Both male and female leopards typically reach sexual maturity at the age 2–2.5 years.

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. Leopards have had cultural roles in Ancient Greece, West Africa and modern Western culture. Leopard skins have been popular in fashion.

Etymology

The English name "leopard" comes from Old French or Middle French , that derives from Latin and ancient Greek (). could be a compound of (), meaning , and (), meaning . The word originally referred to a cheetah (''Acinonyx jubatus'').

"Panther" is another common name, derived from Latin and ancient Greek (); The generic name ''Panthera'' originates in Latin , a hunting net for catching wild beasts to be used by the Romans in combats. is the masculine singular form.

Characteristics

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 underbelly is white 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 rainforest habitats. Rosette patterns are unique in each individual. This pattern is thought to be an adaptation to dense vegetation with patchy shadows, where it serves as camouflage.

Its white-tipped tail is about long, white underneath and with spots that form incomplete bands toward the end of the tail.
The guard hairs protecting the basal hairs are short, in face and head, and increase in length toward the flanks and the belly to about . Juveniles have woolly fur that appear to be dark-coloured due to the densely arranged spots.
Its fur tends to grow longer in colder climates.
The leopard's rosettes differ from those of the jaguar (''Panthera onca''), which are darker and with smaller spots inside. The leopard has a diploid chromosome number of 38.

Melanistic leopards are also known as black panthers. Melanism in leopards is caused by a recessive allele and is inherited as a recessive trait.
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.

Size

The leopard is a slender and muscular cat, with relatively short limbs and a broad head. It is sexually dimorphic with males larger and heavier than females. Males stand at the shoulder, while females are tall. The head-and-body length ranges between with a long tail. Sizes vary geographically. Males typically weigh , and females . Occasionally, large males can grow up to . Leopards from the Cape Province in South Africa are generally smaller, reaching only in males.
The maximum recorded weight of a wild leopard in Southern Africa was around , and it measured . In 2016, an Indian leopard killed in Himachal Pradesh measured with an estimated weight of ; it was perhaps the largest known wild leopard in India.

The largest recorded skull of a leopard was found in India in 1920 and measured in basal length, in breadth, and weighed . The skull of an African leopard measured in basal length, and in breadth, and weighed .

Taxonomy

''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 designated 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''.

Living subspecies

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:

Results of an analysis of molecular variance and pairwise fixation index of 182 African leopard museum specimens showed that some African leopards exhibit higher genetic differences than Asian leopard subspecies.

Evolution

Results of phylogenetic studies based on nuclear DNA and mitochondrial DNA 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.

Results of a phylogenetic analysis of chemical secretions amongst cats indicated that the leopard is closely related to the lion.
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 on the island due to the Toba eruption about 75,000 years ago, and due to competition with 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. Leopard fossils have also been found in Taiwan.

Hybrids

In 1953, a male leopard and a female lion were crossbred in Hanshin Park in Nishinomiya, Japan. Their offspring known as a leopon was born in 1959 and 1961, all cubs were spotted and bigger than a juvenile leopard. Attempts to mate a leopon with a tigress were unsuccessful.

Distribution and habitat

The leopard has the largest distribution of all wild cats, occurring widely in Africa, 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 in the Arabian Peninsula are small and fragmented. In southeastern Egypt, a leopard killed in 2017 was the first sighting of the species in this area in 65 years.
In western and central Asia, it avoids deserts, areas with long snow cover and close proximity to urban centres.

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 in the Shivalik Hills and Gangetic plains, Central India and Eastern Ghats, Western Ghats, 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 it lives in nearby areas.

In Nepal's Kanchenjunga Conservation Area, a melanistic leopard was photographed at an elevation of by a camera trap in May 2012. In Sri Lanka, leopards were recorded in Yala National Park and in unprotected forest patches, tea estates, grasslands, home gardens, pine and eucalyptus plantations.
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 elevations from sea level to . Outside protected areas, leopards were recorded in mixed agricultural land, secondary forest and production forest between 2008 and 2014.

In the Russian Far East, it inhabits temperate coniferous forests where winter temperatures reach a low of .

Behaviour and ecology

The leopard is a solitary and territorial animal. It is typically shy and alert when crossing roadways and encountering oncoming vehicles, but may be emboldened to attack people or other animals when threatened. 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, also called "sawing", as it resembles the sound of sawing wood. Cubs call their mother with an ''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 mainly active from dusk till dawn and will rest for most of the day and some hours at night in thickets, among rocks or over tree branches. Leopards have been observed walking across their range at night; wandering up to 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 vary between seasons.

Leopards can climb trees quite skillfully, often resting on tree branches and descending headfirst.
They can run at over , leap over horizontally, and jump up to vertically.

Social spacing

In Kruger National Park, most leopards tend to keep apart. Males occasionally interact with their partners and cubs, 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 home ranges that often overlap with a few smaller female home ranges, 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 home ranges that overlap extensively, probably due to the association between mothers and their offspring. There may be a few other fluctuating home ranges belonging to young individuals. It is not clear if male home ranges 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 home ranges was not significantly affected by sex, rainfall patterns or season; the higher the prey availability in an area, the greater the leopard population density and the smaller the size of home ranges, but they tend to expand if there is human interference.
Sizes of home ranges vary geographically and depending on habitat and availability of prey. In the Serengeti, males have home ranges of and females of ; but males in northeastern Namibia of and females of . They are even larger in arid and montane areas. In Nepal's Bardia National Park, male home ranges of and female ones of are smaller than those generally observed in Africa.

Hunting and diet

The leopard is a carnivore that prefers medium-sized prey with a body mass ranging from . Prey species in this weight range tend to occur in dense habitat and to form small herds. Species that prefer open areas and have well-developed anti-predator strategies are less preferred. More than 100 prey species have been recorded. The most preferred species are ungulates, such as impala (''Aepyceros melampus''), bushbuck (''Tragelaphus scriptus''), common duiker (''Sylvicapra grimmia'') and chital (''Axis axis''). Primates preyed upon include white-eyelid mangabeys (''Cercocebus'' sp.), guenons (''Cercopithecus'' sp.) and gray langurs (''Semnopithecus'' sp.). Leopards also kill smaller carnivores like black-backed jackal (''Lupulella mesomelas''), bat-eared fox (''Otocyon megalotis''), genet (''Genetta'' sp.) and cheetah.

The largest prey killed by a leopard was reportedly a male eland weighing . 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 (''Elaphodus cephalophus'') to pursuing bamboo rats (''Rhizomys sinense'') and other smaller prey.

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, they have also been observed hunting by day. They usually hunt on the ground. In the Serengeti, they have been seen to ambush prey by descending on it from trees.

It stalks its prey and tries to approach as closely as possible, typically within of the target, and, finally, pounces on it and kills it by suffocation. It kills small prey with a bite to the back of the neck, but holds larger animals by the throat and strangles them. It caches kills up to apart. It is able to take large prey due to its 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 up into a tree. It eats small prey immediately, but drags larger carcasses over several hundred meters and caches it safely in trees, bushes or even caves; this behaviour allows the leopard to store its prey away from rivals, and offers it an advantage over them. The way it stores the kill depends on local topography and individual preferences, varying from trees in Kruger National Park to bushes in the plain terrain of the Kalahari.

Average daily consumption rates of were estimated for males and of for females. In the southern Kalahari Desert, 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''), watermelon (''Citrullus lanatus'') and Kalahari sour grass (''Schmidtia kalahariensis'').

Enemies and competitors

In parts of its range, the leopard is sympatric with other large predators such as the tiger (''Panthera tigris''), lion (''P. leo''), cheetah (''Acinonyx jubatus''), spotted hyena (''Crocuta crocuta''), striped hyena (''Hyaena hyaena''), brown hyena (''Parahyaena 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, killing vulnerable bear cubs instead. In Sri Lanka, a few recorded fights between leopards and sloth bears (''Melursus ursinus'') apparently result in both animals winding up either dead or grievously injured. Leopards generally avoid large packs of African wild dogs and dholes and will flee up a tree at the sight of them.

While interspecies killing of full-grown leopards is generally rare, given the opportunity, both the tiger and lion readily kill and consume both young and adult leopards. In the Kalahari Desert, leopards frequently lose kills to brown hyenas, if they are unable to move the kill up 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 kill smaller prey, usually less than , where tigers are present.
In areas where leopards and tigers are sympatric, coexistence is reportedly not the general rule, with leopards being few where tigers are numerous. Tigers appear to inhabit the deep parts of the forest while leopards are pushed closer to the fringes. In tropical forests, leopards do not always avoid the larger cats by hunting at different times. With relatively abundant prey and differences in the size of the selected prey, tigers and leopards seem to successfully coexist without competitive exclusion or interspecies dominance hierarchies that may be more prevalent in the leopard's co-existence with the lion in savanna habitats.

Nile crocodiles (''Crocodylus niloticus'') occasionally prey on leopards. In one occasion, a large adult leopard was grabbed and consumed by a large crocodile while attempting to hunt along a river bank in Kruger National Park. Mugger crocodiles (''C. palustris'') reportedly killed an adult leopard in Rajasthan. An adult leopard was recovered from the stomach of a Burmese python (''Python bivittatus''). In the Serengeti National Park, troops of around 30–40 olive baboons (''Papio anubis'') were observed mobbing and attacking a female leopard and her cubs.

Reproduction and life cycle

In some areas, leopards mate all year round. In Manchuria and Siberia, they mate during January and February. On average, females begin to breed between the ages of 2½ and three, and males between the ages of two and three. The female's estrous cycle lasts about 46 days, and she is usually in heat for 6–7 days. The generation length of the leopard is 9.3 years. Gestation lasts for 90 to 105 days. Cubs are usually born in a litter of 2–4 cubs. The mortality rate of cubs is estimated at 41–50% during the first year. Lions and spotted hyenas are the biggest cause for leopard cub mortality during their first year. Male leopards are known to cause infanticide, in order to bring the female back into heat. Intervals between births average 15 to 24 months, but can be shorter, depending on the survival of the cubs.

Females give birth in a cave, crevice among boulders, hollow tree or thicket. Newborn cubs weigh , and 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. They begin to eat meat at around nine weeks. Around three months of age, the young begin to follow the mother on hunts. At one year of age, cubs can probably fend for themselves, but will remain with the mother for 18–24 months. After separating from their mother, sibling cubs may travel together for months. Both male and female leopards typically reach sexual maturity at 2–2⅓ years.

The average life span of a leopard is 12–17 years. The oldest leopard was a captive female that died at the age of 24 years, 2 months and 13 days.

Conservation

The leopard is listed on CITES Appendix I, and trade is restricted to skins and body parts of 2,560 individuals in 11 sub-Saharan countries. 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. Contemporary records suggest that the leopard occurs in only 25% of its historical range.

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.

In Java, the leopard is threatened by illegal hunting and trade. Between 2011 and 2019, body parts of 51 Javan leopards were seized including six live individuals, 12 skins, 13 skulls, 20 canines and 22 claws.

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.

Human interaction

Cultural significance

Leopards have been featured in art, mythology and folklore of many countries. In Greek mythology, it 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 rescued him. During the Benin Empire, the leopard was commonly represented on engravings and sculptures and was used to symbolise the power of the king or '' oba'', since the leopard was considered the king of the forest. The Ashanti also used the leopard as a symbol of leadership, and only the king was permitted to have a ceremonial leopard stool. Some African cultures considered the leopard to be a smarter, better hunter than the lion and harder to kill.

In Rudyard Kipling's "How the Leopard Got His Spots", one of his ''Just So Stories'', a leopard with no spots in the Highveld lives with his hunting partner, the Ethiopian. When they set off to the forest, the Ethiopian changed his brown skin, and the leopard painted spots on his skin. A leopard played an important role in the 1938 Hollywood film ''Bringing Up Baby''. African chiefs, European queens, Hollywood actors and burlesque dancers wore coats made of leopard skins.

The leopard is a frequently used in heraldry, most commonly as '' passant''. 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. Naturalistic leopard-like depictions appear on the coat of arms of Benin, Malawi, Somalia, the Democratic Republic of the Congo and Gabon, the last of which uses a black panther.

Attacks on people

The Leopard of Rudraprayag killed more than 125 people; the Panar Leopard was thought to have killed over 400 people. Both were shot by British hunter Jim Corbett. The ''spotted devil of Gummalapur'' killed about 42 people in Karnataka, India.

In captivity

The ancient Romans kept leopards in captivity to be slaughtered in hunts as well as execute criminals. In Benin, leopards were kept and paraded as mascots, totems and sacrifices to deities. Several leopards were kept in a menagerie originally established by King John of England 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. In modern times, leopards have been trained and tamed in circuses.
