National Geographic: Land of the Tiger (1985)
December.
It is winter in Kanha National Park in central India. These very same grasslands and forests were the inspiration for Rudyard Kipling's immortal Jungle Book stories. The spirit of wild India that he evoked still lives here. Kanha National Park is prime tiger country. Sixty years ago its 363 square miles were part of vast primordial forests. Since then these forests have been denuded on a gigantic scale. But Kanha has been preserved in its pristine state. The tiger still roars here, still spreads his dread. Just before dawn this male tiger killed a sambar stag. Now, a few hours later, he drags his prize into deep cover to hide it from the prying eyes of vultures. Like all of his kind he is solitary for most of his life a lone hunter who lives by stealth. The night has been cold. The gray langur monkeys, after their first meal of the day, rest and groom each other in the warmth of the early sun. winter is the season of birth for most langurs. This newborn, only a few hours old, is the center of attraction. The new member of the troop is passed from one female to another as many as ten times in half an hour. It is treated with great curiosity and affection. This "aunt" behavior, as it is called, inducts the infant into the troop, makes it feel welcome and secure. The monsoon rains ceased more than two months ago. But along the streams the vegetation is still green. Grass-shrouded water holes are perfect hiding places from which the tiger tries to ambush the chital. Despite his power and camouflage the tiger often fails to make a kill. Only about one hunt in twenty ends in success. In mid-January, when winter is at its coldest, the rut of the barasingha reaches its peak. During this season of courtship and mating, stages bugle and fight to establish who among them will mate with the does. A tigress watches the combat from her cave where she is hiding newborn cubs. Helpless young with great fierceness and devotion. It will be some weeks before she will bring her cubs out into the open. For the most part, Kanha's tigers remain elusive and mysterious, concealed by the dense undergrowth and the jungles of grass. But in Ranthambhor National Park the habitat is drier and more open. In February, early spring in India, Ranthambhor's 64 square miles are already parched. The monsoon rains are only a vague memory. But cradled in the hills is a chain of lakes, and it is because of this permanent water that wild animals flourish here. Unlike pristine Kanha, Ranthambhor has a long history of human occupation dating back to the 11th century. Dominating the reserve is Ranthambhor fort. Now deserted by man, the fort has become the haunt of animals. Centuries ago it was the focal point of a vigorous city. Battles raged back and forth over the hills. In more recent times villages thrived deep inside Ranthambhor. But their inhabitants have also gone. They were encouraged to settle on better land outside the park. Monuments to forgotten dramas dot the reserve. This stone marks the spot where a widow committed suttee where she burned herself alive on her husband's funeral pyre. Only the ruins remain. Man has moved out of Ranthambhor after almost a thousand years and returned it to the wildlife. On this cool spring morning it is not an ancient warrior who keeps vigil, but a tigress on the lookout for sambar, her favorite prey. When the sambar lie down to chew their cud, they are still out of range The tigress waits patiently. The deer's senses of smell and hearing are acute, but their vision is only moderate. As long as he tigress moves very, very slowly or remains motionless she cannot be been by them, even when only 30 or 40 feet away. Her camouflage hides her completely. The wind shifts and the tigress is scented. The hunt is over. A tigress stakes her claim to her home range by spraying prominent trees and bushes Male tigers mark their territories in a symbolic fashion. The size of a tiger's home range thus marked out varies widely. On the average a female's territory is some ten square miles. Males have much larger territories which overlap those of the females. When one tiger smells the scent of another it grimaces in what is called a "flehmen" display. By following scent markings and listening for roars, males and females find each other. The pair stays together for two or three days and mates frequently for some periods as often as every 10 to 15 minutes. The hills are almost devoid of nutritious grazing. The sambar must come to the lake to feed on water plant. The deer and the mugger crocodiles share the lake peaceably. The sambar are nervous and uneasy ready to flee at the slightest sound or movement. The constant and hidden menace of the tiger haunts their every move. Though he failed to make a kill, as is so often the case, this exceptionally bold and athletic male specializes in hunting from ambush around the lakes. Early the next morning this same tiger finally killed a sambar in the lake. But to his fury the crocodiles have snatched it from him. Intimidated by the crocodiles' strangely aggressive behavior, the tiger reluctantly retreats. But like all of his kind he does not give up his quarry easily. For nine hours the tiger waits. When sambar come down to drink, he is not distracted from his purpose. Finally he summons up enough courage to reclaim his kill. The water is deep, and it takes a supreme feat of strength to swim through the water plants while dragging the 250-pound sambar. The crocodiles' teeth are designed to seize and hold prey, not to cut through skin. During all the hours the sambar lay in the water, they were unable to penetrate the deer's tough hide. The crocodiles make a few token objections, but in the end give up without a struggle. During the night a tigress has brought down a large sambar doe. The ever present tree pies are already in attendance. The birds eat only miniscule amounts, but the tigress resents any interference with her kill and relentlessly chases them off. Her usual strategy for dealing with constantly pestering scavengers would be to drag the carcass to a hiding place. But this kill is too heavy, the terrain too difficult. Another ruse would be to cover it with dry grass or leaf litter. But these are absent here, and the stones she tries to rake over her prize are ineffectual. The only thing left to do is to guard her kill by virtually lying on top of it. The kill is well worth protecting for she can expect to feed on it for four days or more. The next morning the tigress in not at her kill. During the night it has been wrested from her by a male. She watches from a distance while the male feeds on her sambar. Wisely the tigress does not stay to dispute the ownership of the kill. She retreats to a spring deep in a ravine. Another tigress did fight over a kill. She came off second best. Spring is the rutting season for the sambar in Ranthambhor. The stages spray themselves with their male scent. In this way they become more attractive to the does and more intimidating to other males. In April, as spring changes to summer, it becomes drier and hotter. For the sambar the squeeze between the need to drink and eat in the lakes and running the gauntlet of tigers in ambush becomes ever tighter. The sambar, alert and cautious at all times, cannot see the tiger. To them the tall grass is like a blank wall. May is the height of summer in Ranthambhor. Tigers stay close to the water holes. Another six weeks of relentless heat must pass before the monsoon brings relief. Kanha, in the meantime, has also dried out in the summer heat. But because it is a less arid region, many trees and shrubs remain green. The streams have ceased to flow. Only sporadic water holes remain. Moisture is at a premium. Even a patch on wet sand is prized by a blizzard of thirsty butterflies. The cubs of the cave-dwelling tigress have grown. The two, a male and a female, are now five months old. The cave has a commanding view, and the tigress keeps watch for possible prey and for anything that may be a threat to her cubs. In late afternoon the tigress sets off to hunt. The cubs follow her. Before she has gone very far the tigress meets a real danger to her young, the resident male tiger. She calls on all her ferocity to challenge the much larger animal. Territorial males, which are known to kill cubs, are the main threat to the young tigers. After the frightening confrontation, the female cub seeks reassurance. The summer heat continues. Every day it is 105 degrees or more in the shade. The few water holes are shrinking. Animals must travel long distances to drink. As in Ranthambhor, there is a constant threat from the well camouflaged tigers A white-breasted kingfisher has taken up residence and bathes frequently to cool himself. Langur monkeys spend hours licking salt and other minerals from the rocks that surround the pool. The water hole attracts a multitude of birds. Even the shy red junglefowl, the gaudy ancestor of the domestic chicken, must leave the protection of the forest to drink. A lesser adjutant stork probes the water hole for fish and frogs. The checkered keelback snake is an unwelcome visitor treated with circumspection by the other animals. But the reptile is no threat to most of them. It is non-venomous and a confirmed fish-eater. The deserted water hole no longer has any interest for the tiger. When the oppressive heat of the day abates, the barasingha emerge from the forest to drink. It is a time too when the tigress and her cubs leave their cave. Before she sets out to feed on the remains of a sambar she killed two nights ago, the tigress suckles her young during an interlude of extraordinary peace and tenderness. This morning the tigress did not bring the cubs to her kill even though they are old enough to eat meat for themselves. Danger in the form of the male tiger is still near. When the male approaches, she hides the remains of her prey, covering it with leaves. She will stay with in until the threat has passed. Early June is the hottest, driest time of the year. The shade temperature rises to 110 degrees. Tigers suffer more than most animals in this heat. Then one day in mid-June, as the koel and the brainfever bird scream for rain, a cool wind whips up; the air becomes humid. The monsoon has finally arrived. For four days it rains sometimes lightly, sometimes in torrents. The temperature drops about 20 degrees The heat, the dry streams, the brittle bleached grasses, the aridity of eight virtually rainless months have disappeared at one stroke. After the monsoon's first days of rain the sun briefly reappears. Kanha has been transformed, has taken on a cloak of fresh new green. Termites celebrate the onset on the monsoon with mating flights. Velvet-textured mites erupt out of the ground and feast on the termites. Male bullfrogs vie for the females in duels of sound. Life has been liberated by the rain. Plants explode into untrammeled growth The new lushness attracts hordes of leaf-eating insects, and when the caterpillars unleash their appetites on the monsoon's bounty, they are an effective restraint on the new leaves. In July, when the monsoon is firmly established, the chital gather on the grassland, which soon reverberate with the sounds and energy of their rut. A peacock unfurls his train a symbol for the renewal and exuberance of life A predator other than the tiger, and one feared by all the animals, moves down from the hills at this time of year, spreading disquiet in forest and grassland alike. It is the Indian wild dog. No animal is safe from these marauders and even the mighty tiger will usually avoid a direct confrontation. The dogs move in packs that may number up to 30. though an individual wild dog could never challenge the supremacy of the tiger, large packs have been known to attack him. During such a fight the big cat can inflict heavy casualties. Once a besieged tiger destroyed 12 dogs before he himself was killed and eaten As the younger dogs play, they are watched by a mob of near-hysterical chital. The herd rushes into the forest where the pack will soon follow. The incapacitated are left behind. The lush grasses lure the reclusive gaur, or Indian bison, out of their forest strongholds. These are the largest wild cattle in the world. A large bull stands over six feet at the shoulder and may weight up to 2,000 pounds. The adults have little to fear from the tiger. It is the calves and yearlings that are vulnerable. Whenever a tiger is detected, when the cows and bulls snort and toss their heads in threat the big cat has no chance of making a kill. To the contrary, an alerted herd can be a danger to the tiger. At the turn of the century some 40,000 tigers stalked India's jungles. By 1972 they numbered fewer than 2000. This grim fact was the signal for courageous and far-reaching conservation efforts. These have been so effective that if the tiger is to survive in the wild its best chance is now probably in India, in reserves like Kanha and Ranthambhor where the tiger has already made an impressive comeback. With Kanha's riches restored by the monsoon, the tiger is no longer tied to a few scant water holes. It wanders widely and leaves the plains for the denser vegetation of the hills A green curtain is drawn over its presence, and the tiger becomes more elusive than ever, a hidden force that inspires even greater dread among all the animals that live under its tyranny. |
