Indian leopard

Felis fusca was the scientific name proposed by Friedrich Albrecht Anton Meyer in 1794 who described a black leopard from Bengal that was on display at the Tower of London. Leopardus perniger proposed by Brian Houghton Hodgson in 1863 were five leopard skins from Nepal, out of which three were black. He mentioned Sikkim and Nepal as habitat. Panthera pardus millardi proposed by Reginald Innes Pocock in 1930 was a single leopard skin and skull from Kashmir. It differed from typical P. p. fusca skins by longer hair and a more greyish colour. Since leopard populations in Nepal, Sikkim and Kashmir are not geographically isolated from leopard populations in the Indian subcontinent, they were subsumed to P. p. fusca in 1996. The Indus River in the west and the Himalayas in the north form topographical barriers to the dispersal of this subspecies. In the east, the Ganges Delta and the lower course of the Brahmaputra River are thought to form natural barriers to the range of the Indochinese leopard. ==Characteristics==

The Indian leopard has strong legs and a long, well-formed tail, broad muzzle, short ears, small, yellowish-grey eyes, and light-grey ocular bulbs. Juveniles have woolly fur, and appear dark due to the densely arranged spots. The white-tipped tail is long, white underneath, and displays rosettes, which form incomplete bands toward the end. The rosettes are larger in other leopard subspecies in Asia. Fur colour tends to be more pale and cream in arid habitats, more grey in colder climates, and of a darker golden hue in rainforest habitats. The clouded leopard can be told apart by its diffuse "clouds" of spots compared to the smaller and distinct rosettes of the leopard, longer legs and thinner tail. Skull The largest skull for an Indian leopard was recorded in 1920, and belonged to a large, melanistic cat in the area of Ootacamund, Tamil Nadu. The black panther was said to have bigger forelimbs and forequarters than hind-limbs and hind-quarters, with a skull and claws nearly as large as those of a tigress. The skull measured in basal length, and in breadth, and weighed . By comparison, the skull of one western African leopard measured in basal length, and in breadth, and weighed . Size Male Indian leopards grow to between and in body size with a to long tail and weigh between . Females are smaller, growing to between and in body size with a to long tail, and weigh between . Sexually dimorphic, males are larger and heavier than females. ==Distribution and habitat==

The Indian leopard is distributed in India, Nepal, Bhutan and parts of Pakistan. It inhabits tropical rainforests, dry deciduous forests, temperate forests and northern coniferous forests but does not occur in the mangrove forests of the Sundarbans. In Nepal's Kanchenjunga Conservation Area, a melanistic leopard was photographed at an elevation of by a camera trap in May 2012. Population in India In 2015, 7,910 leopards were estimated to live in and around tiger habitat in India; about 12,000 to 14,000 leopards were speculated to live in the entire country. The following table gives the major leopard populations in the Indian states. 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, as well as the Brahmaputra River basin and hills in Northeast India. As per 2022, the Indian leopard population was estimated at 13,874 individuals. ==Behaviour and ecology==

The leopard is elusive, solitary, and largely nocturnal. It is known for its ability in climbing, and has been observed resting on tree branches during the day, dragging its kills up trees and hanging them there, and descending from trees headfirst. It is a powerful swimmer, although is not as disposed to swimming as the tiger. It is very agile, and can run at over , leap over horizontally, and jump up to vertically. It produces a number of vocalizations, including grunts, roars, growls, meows, and purrs. In Nepal's Bardia National Park, home ranges of male leopards comprised about , and of females about ; female home ranges decreased to when they had young cubs. In Gir National Park, the home range of a male radio-collared leopard was estimated at . It killed prey once in 3.7 days. The leopard is a versatile, opportunistic hunter, and has a very broad diet. In Sariska Tiger Reserve, the dietary spectrum of the Indian leopard includes axis deer, sambar deer, nilgai, wild boar, common langur, Indian hare and peafowl. In Periyar Tiger Reserve, primates make up a large proportion of its diet. Reproduction Depending on the region, the leopard mates all year round. 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 grey 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. Sympatric carnivores Indian leopards are not common in habitats where tiger density is high, and are wedged between prime tiger habitat on the one side, and cultivated village land on the other. Where the tiger population is high or increasing, tigers drive leopards off to areas located closer to human settlements, like in Nepal's Bardia National Park and Sariska Tiger Reserve. Resource partitioning occurs where leopards share their range with tigers. Leopards tend to take smaller prey, usually less than , 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 population density decreased significantly from 9.76 to 2.07 animals per , while the mean tiger population density 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 in weight with most kills in the range. Tigers killed more prey in the 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 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. The leopard and snow leopard both hunt Himalayan tahr and musk deer, but the leopard usually prefers forested habitats located at lower elevations. Leopard may conflict with sloth bears and can follow them up trees. Bear cubs are probably far more vulnerable and healthy adult bears may be avoided by leopards. One leopard killed a three-quarters grown female sloth bear in an apparently lengthy fight that culminated in the trees. Apparently, a sloth bear killed a leopard in a confrontation in Yala National Park, Sri Lanka but was itself badly injured in the fight and was subsequently put down by park rangers. ==Threats==

Hunting of Indian leopards for the illegal wildlife trade is the biggest threat to their survival. They are also threatened by loss of habitat and fragmentation of formerly connected populations, and various levels of human–leopard conflict in human–dominated landscapes. Poaching A significant immediate threat to wild leopard populations is the illegal trade in poached skins and body parts between India, Nepal and China. The governments of these countries have failed to implement adequate enforcement response, and wildlife crime remained a low priority in terms of political commitment and investment for years. There are well-organised gangs of professional poachers, who move from place to place and set up camp in vulnerable areas. Skins are rough-cured in the field and handed over to dealers, who send them for further treatment to Indian tanning centres. Buyers choose the skins from dealers or tanneries and smuggle them through a complex interlinking network to markets outside India, mainly in China. Seized skins in Kathmandu confirm the city's role as a key staging point for illegal skins smuggled from India bound for Tibet and China. It is likely that seizures represent a tiny fraction of the total illegal trade, with the majority of smuggled skins reaching their intended end market. then again in 2002-2010 period at least 200 or four leopards per week were reportedly killed by poachers for illegal trade. For every tiger skin, there are at least seven leopard skins in the haul. • in Nepal: more than 40 leopards were reported killed by humans every year, e.g. 243 poached leopards between May 2002 and May 2008; • in China and Tibet: nearly 130 leopards were killed every year, e.g. more than 774 poached leopards between July 1999 and September 2005. India's Forest Department is entitled to set up traps only in cases of a leopard having attacked humans. If only the presence of a crowd of people prevents the leopard from escaping, then the crowd has to be dispersed and the animal allowed to escape. As urban areas expanded, the natural habitats of leopards shrunk resulting in leopards venturing into urbanized areas due to easy access of domestic food sources. Karnataka has a high number of such conflicts. In recent years, leopards were sighted in Bangalore, and the forest department captured six leopards in the city's outskirts, relocated four of them to various other locations. Man-eater leopards Every year more leopards are killed by humans than the humans killed by leopards. On average nearly 400 leopards are reported killed yearly in India, Nepal and China combined based on the leopard skins caught from the poachers, The frequency of Leopard attacks on humans varies by geographical region and historical period. Since India and Nepal have the majority of Indian leopards population, consequently attacks are regularly reported only from India and Nepal. Among the five "big cats", leopards are less likely to become man-eaters—only jaguars and snow leopards have a less fearsome reputation. While leopards generally avoid humans, they tolerate proximity to humans better than lions and tigers and often come into conflict with humans when raiding livestock. Attacks in India are still reported, since leopards population in India outnumber population of all other large carnivores combined, consequently the number of humans killed by leopards is also more than those killed by all other large carnivores combined. In Nepal, where most attacks occur in the midland regions, i.e. in the Terai, midhills, and lesser Himalaya, the rate of leopard predation on humans results in approximately 1.9 human deaths annually per million inhabitants. . Ways to minimise conflict Key to avoiding conflict or leopard's predation of humans is to shift the focus on human's behavioral change to minimise the chances of a leopard encounter or attack, which can be achieved by "clearing bushes and overgrowth around homes to minimise hiding spaces for leopards, leaving a light on at night to deter them, and ensuring people, especially children, did not go out alone at night." Leopards are shy and avoid humans and are more active at night, during encounter with leopards "give way to the leopard and move away calmly" and alert the forest department immediately. ==Conservation==

Panthera pardus is listed in CITES Appendix I. Bhutan, and Nepal but Critically Endangered in Pakistan. Frederick Walter Champion was one of the first in India who after World War I advocated for the conservation of leopards, condemned sport hunting and recognised their key role in the ecosystem. Billy Arjan Singh championed their cause since the early 1970s. There are a few leopard rescue centres in India, such as the Manikdoh Leopard Rescue Centre in Junnar, but more rescue and rehabilitation centres are being planned. Some wildlife experts think that such centres are not an ideal solution, but that conflict resolution by way of changing human behaviour, land use or grazing patterns and implementing responsible forest management to lessen human-animal conflict would be far more effective to conserve leopards. ==In culture and literature==

• An Indian black panther named 'Bagheera' is featured in Rudyard Kipling's 1894 novel The Jungle Book, as well as in Disney's 1967 and 2016 film adaptations. • The book Man-Eaters of Kumaon is based on man-eating leopards and tigers in Kumaon Division. • Ajoba is a 2014 Marathi film directed by Sujay Dahake and written by Gauri Bapat. It is supposedly based on true events. • Local people in the Western Ghats call a darkish grey panther pogeyan, which purportedly lives in the high-elevation grasslands of the Anamudi forest. ==See also==
