Information Regarding Siberian Tiger

Residing in the Conifer and Broadleaf forests east of the Amur River, the Siberian Tigers are solitary cats that enjoy a relatively undisturbed ecosystem devoid in large parts of human activity. Occupying huge territories of up to four thousand square miles, these Amur Tigers are often on the move, covering large distances in search of prey in their isolated wilderness. One Siberian Tiger was once recorded to cover over six hundred miles in the space of three weeks in search of food. The great cat hunts a variety of animals including moose, roe deer, sika deer, musk deer and goral, though red deer and wild boar form the bulk of its diet.

Opportunistic predators, the tigers are known to take even rabbits, hares, pikas and fish (usually salmon) at times. The undisputed king of carnivora, the Siberian Tiger spares not even the Great Russian Brown Bear from its predatory activities. The cats pull out the bears while they are hibernating and attack and kill them. At other times, brown bear kills have been recorded in the open, displaying the superiority of the tiger over the bear as the apex predator on land. The Asiatic black bears are not given any respite by a hungry tiger either. The cunning cat is known to imitate black bear sounds to attract and hunt them.

Even resilient pack animals such as wolves have been nearly exterminated by the tigers. A stalk and ambush predator, the Amur Tiger despite its great power still only succeeds in ten to fifteen percent of hunting attempts. The cat prefers to creep up to ten to twenty five meters of the prey animal before rushing and pouncing upon it, moving at speeds of up to 80 km/hr in its charge. Smaller prey animals are killed by a bite on the nape of neck that breaks the vertebrae and severs the spinal cord. Larger game is brought down by a bite on front of the neck that crushes the windpipe and suffocates the prey. Needing around twenty pounds of meat daily to survive in the wild, the tiger can consume about sixty to hundred pounds in one setting. The kill is often cached, usually near a water body and the cat has been known to return to carcasses to complete its feed.

The Siberian Tiger inhabits the Boreal forests in Far Eastern Asia, residing largely in Russia but also reported in China and North Korea. Panthera Tigris Altaica, it is seen largely in the Amur-Ussuri region of Primorsky and Khabarovsky Krai. Its range has shrunk drastically in the past hundred years and is now a mere fraction of its past domain.

The tigers are known to mate at any time during the year. The receptive female advertises her presence by leaving urine and scratch markings on trees. She is in estrus typically for three to seven days during which the pair mates several times. Like all big cats, the courting individuals focus less on hunting during this time and are particularly hostile to any intruders. Up to six cubs are born after a pregnancy lasting between three to three and a half months, though three to four is the average litter size. Blind and helpless they are sheltered in a den by the ever watchful mother who seldom leaves them during the early weeks, going out only for hunting.

The young open their eyes at two weeks and begin to venture outside at around three months. They are weaned off at around six months and begin to accompany their mother at her hunting trips at this age. Small prey is successfully taken down by the cubs at less than one year of age, and large prey at twice that age. They stay with their mother at up until three to five years of age after which they begin to venture and establish their territories and fend for themselves. Males generally move farther away from their realm, making them easier targets for poachers. As a result adult male tigers are outnumbered by females three to one on average. Lifespan is known to be up to twenty five years.

Amur Tigers were freely hunted in the early part of this century, bringing them to near extinction in most territories. In 1947 hunting was outlawed in the former Soviet Union. Still the tiger continued to suffer at the hands of poachers who made heavy profits by selling the body parts to Chinese traditional medicine makers, earning up to fifty thousand dollars with one tiger. The collapse of Soviet Union accompanied with the breakdown of law and order infrastructure had a particularly adverse impact on the tiger population whereby nearly sixty tigers were reputedly killed yearly by poachers in the few years following 1989. In 1992, The Siberian Tiger Project was founded. This marked the beginning of a turn around in the fate of tiger. In 1993, Chinese Government declared the use of tiger parts for medicinal purposes to be illegal.

In the following years, vigilant monitoring and study resulted in the stabilization of tiger numbers in the wild. Regular patrols were undertaken to deter the poachers and individual tigers were studied to better understand the subspecies and reduce its mortality in its natural habitat. Another successful step was launching of Operation Amba in Russia that continues to protect the Siberian Tigers through collaboration of law enforcement agencies and interaction with local people. Its mission is to neutralize tiger traders and attack and eliminate poaching rings. It has been largely successful in seizing many poaching materials and saving a number of tiger cubs. As a result of these tireless efforts of forest rangers and scientists, today the population of Siberian Tigers in the wild is believed to be around five hundred individuals and this is merely the number in Russia. In fact the Siberian Tiger is the only tiger subspecies whose population is believed to be on the increase. The impressive recovery of the Siberian Tiger is often used as a model plan to save other species.

Information Regarding the Bengal Tiger

Solitary cats, Bengal Tigers are territorial animals. They hunt at dusk and dawn and regularly mark their territory by scent to keep out other tigers from their hunting and breeding grounds. In some national parks where they are protected, tigers have been recorded to be active in daytime as well. Generally tigers prefer to stay in shade during daylight hours, particularly in the scorching summers of South Asia. Territories are smaller than those of Siberian Tigers owing to shrinking habitat of the tigers in India. Males roam over an area of twenty square miles and females hunt in a slightly smaller range of seventeen square miles. Often the territory of a single male overlaps those of several females, with whom he frequently mates. Tigers usually have more than one den in their range for them to choose as their haunt for a particular period of time.

Bengal Tigers are at the top of their ecosystem and play an active role in maintaining the delicate balance of India's threatened natural fauna and flora. They prey upon a variety of animals including wild boar, sambar, barasingha, nilgai, gaur and water buffalo though the spotted dear, also known as chital, forms the bulk of their diet. At times smaller animals including hares, peacocks, langurs and monkeys are also consumed. Tigers are not above scavenging and often eat putrefied carcasses. Extremely strong, Bengal Tigers are known to attack and kill the largest prey animals in India including the Asiatic Elephant and Rhinoceros. They are estimated to have the strength of twelve adult men and can carry a fully grown cow over a ten foot fence. Aggressive animals, these great cats often kill adult crocodiles over conflict. In reality, nothing is safe from a wild tiger in the jungles of India if it makes up its mind to hunt it.

The most untamed of India's tigers reside in the largest natural delta on earth - the Sunderban forest of Bengal where the sacred river Ganges opens into the Bay of Bengal. An estimated near three hundred and five hundred tigers reside on India and Bangladesh's side of this vast mangrove wetland. Landlocked through ever-changing tides from the hunting maharajahs and colonial British of the past centuries, these wild tigers have never learned to respect man. These tigers are expert swimmers and amongst the most notorious big cats when it comes to man-eating. Their victims are ever so often the honey collectors and fishermen of Sunderban (literally meaning beautiful forest). Even though Core Areas and Buffer Zones have been designated to separate the predator from man, the extremely poor villagers go deep into tiger territory to search for honey and fish.

The result is a number of deaths yearly that the locals have learnt to live with as the continual cycle of life and death in that part of the world. Still the conflict fares badly for the tiger which runs the risk of being poisoned and killed as in many other parts of the subcontinent where it is being victimized, by villagers for revenge, and poachers for profit. Despite its fearsome reputation the tiger is believed to be a large hearted gentleman that generally avoids human by most experts including the famed hunter turned conservationist Jim Corbett who understood more about the big cat more than half a century ago than most do today. Most human kills by tigers according to him were the result of surprise, provocation, old age, injury, loss of prey or coincidence. Once tigers learn that humans are relatively easy and defenseless prey, some take to man-eating.

Recorded in Bangladesh, Bhutan, India, Myanmar, Nepal and parts of Tibet, the Bengal Tiger is essentially the pride of India and Bangladesh where it is given the status of national animal. Highest numbers are known to exist in scattered reserves in India where its numbers have shrunk from tens of thousands nearly a century ago to less than fifteen hundred today. Tigers survive in a variety of tropical habitats including marshlands, brush and grasslands.

Mating season for Bengal Tigers is between winter and spring. Females are receptive for three days to a week. Pregnancy lasts for around three months after which three cubs are born on average. The young are particularly vulnerable to adult male tigers in the vicinity who will frequently kill the cubs they haven't fathered to bring the female into estrus and establish the perpetuity of their own genetic line. At eleven months of age, the cubs are able to hunt for themselves. They stay with their mother for up to two to three years of age after which they move off to fend for themselves and take up a range of their own. Lifespan in the wild is fifteen years, and in captivity seventeen years on average.
