Leopard attack

The Gunsore man-eater after it was shot by British officer W. A. Conduitt on 21 April 1901. Credited with at least 20 human deaths, the leopard was killed on top of its last victim, a child from Somnapur village in the Seoni district, India.

Leopard attacks on humans are generally rare occurrences. Despite the leopard's (Panthera pardus) extensive range from sub-Saharan Africa to Southeast Asia, attacks are regularly reported only in India and Nepal. Among the four "big cats," leopards are less likely to become man-eaters—only jaguars have a less fearsome reputation. There are no known records of snow leopards (Panthera uncia) attacking humans. However, leopards are established predators of non-human primates, sometimes preying on species as large as the western lowland gorilla. Other primates may make up 80% of the leopard's diet. 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.

Leopard attacks may have peaked in India during the late nineteenth and early twentieth centuries, coinciding with rapid urbanization. Attacks in India are still relatively common, and in some regions of the country leopards kill more humans than all other large carnivores combined. The states of Gujarat, Himachal Pradesh, Maharashtra, Uttarakhand, and West Bengal experience the most severe human–leopard conflict. One study concluded that the rate of leopard predation on humans in Nepal is 16 times higher than anywhere else, resulting in approximately 1.9 human deaths annually per 1 million inhabitants. Globally, attacks on humans—especially nonfatal attacks that result in only minor injury—likely remain under-reported due to the lack of monitoring programs and standardized reporting protocol.

Leopard predation on hominids

In 1970 South African paleontologist C. K. Brain showed that a juvenile Paranthropus robustus individual, SK 54, had been killed by a leopard at Swartkrans in Gauteng, South Africa approximately 1.8 million years ago. The SK 54 cranium bears two holes in the back of the skull—holes that perfectly match the width and spacing of lower leopard canine teeth. The leopard appears to have dragged its kill into a tree to eat in seclusion, much like leopards do today. Numerous leopard fossils have been found at the site, suggesting that they were a primary predator of early hominids. The revelation that these injuries were not the result of interpersonal aggression but were leopard-inflicted dealt a fatal blow to the then-popular killer ape theory. Another hominid fossil consisting of a 6-million-year-old Orrorin tugenensis femur (BAR 1003'00), recovered from the Tugen Hills in Kenya, preserves puncture damage tentatively identified as leopard bite marks. This fossil evidence, along with modern studies of primate–leopard interaction, has fueled speculation that leopard predation played a major role in primate evolution, particularly on cognitive development.

Human–leopard conflict

Reducing human–leopard conflict has proven difficult. Conflict tends to increase during periods of drought or when the leopard's natural prey becomes scarce. Shrinking leopard habitat and growing human populations also increase conflict. In Uganda, retaliatory attacks on humans increased when starving villagers began expropriating and scavenging leopard kills (a feeding strategy known as kleptoparasitism). The economic damage resulting from loss of livestock to carnivores caused villagers in Bhutan's Jigme Singye Wangchuck National Park to lose more than two-thirds of their annual cash income in 2000, with leopards blamed for 53% of the losses. Similarly, in the Annapurna Conservation Area of Nepal, the estimated monetary loss per household was US$95 in 2009 and US$42 in 2010 (out of an annual income of less than US$100), with leopards blamed for 94.9% of the losses. Like other large carnivores, leopards are capable of surplus killing. Under normal conditions, prey are too scarce for this behavior, but when the opportunity presents itself leopards may instinctually kill in excess for later consumption. One leopard in Cape Province, South Africa killed 51 sheep and lambs in a single incident.

Translocation (the capture, transport, and release) of "problem leopards," as with other territorial felids, is generally ineffective: translocated leopards either immediately return or other leopards move in and claim the vacant territory. One translocated leopard in Cape Province traveled nearly 500 kilometres (310 mi) to return to his old territory. Translocations are also expensive, tend to result in high mortality (up to 70%), and may make leopards more aggressive towards humans, thus failing as both a management and a conservation strategy. Historically, lethal control of problem animals was the primary method of conflict management. Although this remains the situation in many countries, leopards are afforded the highest legal protection in India under the Wildlife Protection Act of 1972—only man-eaters can be killed and only when they are considered likely to continue to prey on humans. In Uttarakhand, the state with the most severe human–leopard conflict, 45 leopards were legally declared man-eaters by wildlife officials and shot between 2001 and 2010.

Where legal, herders may shoot at leopards who prey on their livestock. An injured leopard may become an exclusive predator of livestock if it is unable to kill normal prey, since domesticated animals typically lack natural defenses. Frequent livestock-raiding may cause leopards lose their fear of humans, and shooting injuries may have caused some leopards to become man-eaters. There has been increasing acceptance that the "problem leopard" paradigm may be anthropomorphization of normal carnivore behavior, and that translocations are unlikely to stop livestock depredation. In an effort to reduce the shooting of "problem leopards" and lessen the financial burden, some governments provide monetary compensation to herders, although the sum is often less than the value of the lost livestock.

Man-eaters

Characteristics

The leopard is largely a nocturnal hunter. For its size, it is the most powerful large felid, able to drag a carcass larger than itself up a tree. Leopards can run more than 60 kilometres per hour (37 mph), leap more than 6 metres (20 ft) horizontally and 3 metres (9.8 ft) vertically, and have a more developed sense of smell than tigers. They are strong climbers and can descend down a tree headfirst. Man-eating leopards have earned a reputation as being particularly bold and difficult to track. British hunters Jim Corbett (1875–1955) and Kenneth Anderson (1910–1974) wrote that hunting leopards presented more challenges than any other animal. Indian naturalist J. C. Daniel (1927–2011), former curator of the Bombay Natural History Society, reprinted many early twentieth-century accounts of man-eating leopards in his book The Leopard in India: A Natural History (Dehradun: Natraj Publishers, 2009). One such account in the Journal of the Bombay Natural History Society describes the unique danger posed by leopards:

Like the tiger, the panther [leopard] sometimes takes to man-eating, and a man-eating panther is even more to be dreaded than a tiger with similar tastes, on account of its greater agility, and also its greater stealthiness and silence. It can stalk and jump, and...can climb better than a tiger, and it can also conceal itself in astonishingly meager cover, often displaying uncanny intelligence in this act. A man-eating panther frequently breaks through the frail walls of village huts and carries away children and even adults as they lie asleep.

One study concluded that only 9 of 152 documented man-eating leopards were female. Drawing on the sex and physical condition of 78 man-eating leopards, the same study concluding that man-eaters were typically uninjured mature males (79.5%), with a fewer number of aged and immature males (11.6% and 3.8%, respectively). Once a leopard has attacked and eaten a human, they are likely to persist as man-eaters—they may even show a nearly exclusive preference for humans. Corbett wrote that the Rudraprayag man-eater once broke into a pen holding 40 goats, but instead of attacking the livestock it killed and ate the sleeping 14-year-old boy who had been assigned to guard them.

Leopard attacks on humans tend to occur at night, and often close to villages. There have been documented incidents of leopards forcing their way into human dwellings at night and attacking the inhabitants in their sleep. A number of fatal attacks have also occurred in zoos and homes with pet leopards. During predatory attacks, leopards typically bite their prey's throat or the nape of the neck, lacerating or severing jugular veins and carotid arteries, causing rapid exsanguination. The spine may be crushed and the skull perforated, exposing the brain. Survivors of attacks typically suffer extensive trauma to the head, neck, and face. Multibacterial infection resulting from the contamination of wounds by leopard oral flora occurs in 5–30% of attack survivors, complicating recovery. Before the advent of antibiotics, 75% of attack survivors died from infection.

Notable man-eaters

Leopard of Panar

The Panar man-eater was a male leopard responsible for at least 400 fatal attacks on humans in the Panar region of the Almora district. Jim Corbett heard of the leopard while hunting the Champawat tiger in 1907, and in 1910 he set out to kill it. Although it claimed hundreds of more lives than the Rudraprayag man-eater, the Panar man-eater recieved less attention by the British Indian press, which Corbett attributed to the remoteness of Almora.

Leopard of the Golis Range

In 1899 British officer H. G. C. Swayne (1860–1940) wrote of a man-eating leopard that had killed more than 100 humans in the Golis Mountains of British Somaliland. Swayne's brief account appears in the volume Great and Small Game of Africa (London: Roland Ward, 1899), edited by the prominent British naturalist Henry Bryden (1854–1937):

In 1889 there was a leopard, said to be a panther, which had haunted the Mirso ledge of the Golis range for some years, and was supposed to have killed over a hundred people. It was in the habit of lying in wait at a corner of a very dark, rough jungle path, where huge rocks overlooked the track; and the Somalis used to show a boulder, some 6 feet high, a yard from the path, in the flat top of which was a depression shaped like a panther's body, from which the beast was said to spring upon travellers.

According to Swayne, leopards were more abundant in the Golis Mountains than anywhere else in British Somaliland, and were responsible for 90% of all attacks on sheep and goats. The rocky terrain of the Golis made tracking and killing leopards next to impossible. At the time of the attacks, this remote territory remained largely unexplored by the British, and little else is known of the Golis Range man-eater.

Leopard of the Mulher Valley

British hunter Jim Corbett poses after shooting the Rudraprayag leopard on 2 May 1926. Estimated to have killed more than 125 people in Uttarakhand, India between 1918 and 1926, it was perhaps the third most prolific man-eater after the Panar leopard and the Central Provinces leopard.

In 1903 L. S. Osmaston (1870–1969), a conservator employed by the Imperial Forestry Service, reported that a man-eating leopard had killed more than 30 humans in the Mulher Valley between 1901 and 1902. Osmaston twice set out to kill the leopard in February and March 1902, but was unsuccessful. His forestry work required him to leave Mulher later that month, and he was unable to return until late November. The leopard's last attack occurred a few days later on 3 December:

I heard a boy of 15 had been killed at Wadai, 4 miles from my camp; this boy was most unfortunate. Last year the panther had tried to get him, but only mauled one leg; my wife and I were able to dose the wound with carbolic oil and the boy got well; this time he and one or two others were sitting close to a bright fire on a threshing floor near the village in the early part of the night and the panther came and carried him off: the panther took him about a quarter of a mile to a patch of high grass and brushwood and ate all he could of the head, the flesh of one leg and all his inside; so there was plenty left for the beast to come back for.

Osmaston constructed a blind 11 metres (36 ft) from the boy's corpse and waited. The leopard returned to the area in the afternoon, but cautiously avoided approaching the body until after dark. When it finally ventured within shooting range, Osmaston fired with his double-barreled express rifle. The injured animal darted off into the night, and was killed the following morning when it was discovered alive some distance away. Osmaston speculated that the attacks began during the Indian famine of 1899–1900, the leopard having taken to man-eating after killing a dying person in the jungle. He also believed the man-eater was responsible for other fatal attacks in the nearby Dang and Dhule districts, but did not know the exact number of fatalities.

Leopard of Kahani

Robert A. Sterndale (1839–1902) and James Forsyth (1838–1871) gave accounts of a man-eating leopard that killed "nearly a hundred persons" in the Seoni district between 1857 and 1860. When Sterndale recieved word of attacks he pursued the man-eater with his brother-in-law, W. Brooke Thomson, but their efforts proved fruitless. The breakout of the Indian Rebellion of 1857 sent Sterndale away for two years and ended his chance to capture the man-eater. The leopard evaded all attempts by locals to kill it and terrorized the villages of Dhuma and Kahani, sometimes killing three humans in a single night. According to Sterndale, the leopard preferred to consume blood rather than flesh, and most bodies showed few injuries other than telltale bite marks to the throat. A large reward was offered for the leopard's capture, and it was then unexpectedly killed one night by an inexperienced native hunter. When Forsyth passed through Seoni several years later, the leopard's story had become legendary. He later recounted a myth he had heard from the locals:

A man and his wife were travelling back to their home from a pilgrimage to Benares, when they met on the road a panther. The woman was terrified; but the man said, "Fear not, I possess a charm by which I can transform myself into any shape. I will now become a panther, and remove this obstacle from the road, and on my return you must place this powder in my mouth, when I will recover my proper shape." He then swallowed his own portion of the magic powder, and assuming the likeness of the panther, persuaded him to leave the path. Returning to the woman, he opened his mouth to receive the transposing charm; but she, terrified by his dreadful appearance and open jaws, dropped it in the mire, and it was lost. Then, in despair, he killed the author of his misfortune, and ever after revenged himself on the race whose form he could never resume.
