Stripe patterns differ among individuals and are as unique to the animal as are fingerprints to humans. The dark lines above the eyes tend to be symmetrical, but the marks on the sides of the face and body can be different. Males have a prominent ruff or collar, which is especially pronounced in the Sumatran tiger. White tigers have been seen in the wild in India, and 1 single white cub taken by the name of Mohan was the progenitor of most white tigers now in captivity. White tigers would never survive in the wild as the white coat is only produced through severe inbreeding. White tigers have brown stripes and crystal blue eyes, and some specimens in captivity have no stripes at all. Black tigers have been reported, but only a single pelt from illegal traders remains the only evidence. The pelt shows that the black only occurs on the top of the head and back, but turns into stripes down the sides, unlike in other cats that are completely and truly black (or melanistic). Body size of the tiger varies with latitude, the smallest occurring at low latitudes in Indonesia and the largest at high altitudes in Manchuria and Siberia. The largest, the Siberian tiger can reach weights exceeding 700 pounds and reach lengths of 10+ feet, and the smallest, the Indonesian or Bali tiger weighing a mere 200 pounds with a total length of 7 ft.
In sanctuaries tigers have lived more than 26 years, as compared to 15 in the wild. Tigers only live 10-12 years in zoos.
Habitat: Tigers occupy a wide variety of habitats including tropical evergreen forests, deciduous forests, coniferous woodlands (Taiga), mangrove swamps, thorn forests and grass jungles. The common factors of all of the tiger's habitats, is some form of dense vegetative cover, sufficient large prey, and access to water. Tigers are extremely adept swimmers and readily take to water. They have been recorded easily swimming across rivers achieving distances of just under 20 miles. The tiger also spends much of its time during the heat of the day during hot seasons half submerged in lakes and ponds to keep cool. Indian tigers generally have a range of 8-60 square miles, based on availability of prey. Sumatran tigers have a range of about 150 square miles. Due to the severity of the climate and lack of prey, the Siberian tiger can require a range of 400 square miles. Tigers have lost more than 40% of their habitat in the past decade. (1)
Distribution: Indian subcontinent, Amur River region of Russia , China, and North Korea, South central China, Sumatra, Indonesia, and Continental southeast Asia
Reproduction and Offspring: Tigers will mate throughout the year, but most frequently between the end of November to early April. After a gestation of 103 days a litter of up to 7 cubs, although averaging 3, is born. Cubs will leave their mothers as young as 18 months old, or as old as 28 months old. During the first year, mortality can be as high as 35%, and of that 73% of the time it is the entire litter that is lost. The main causes of infant mortality are fire, floods, and infanticide, with the latter being the leading cause. Females tend to reproduce around 3 ½ years and males just under 5 years. In captivity, females have produced through age 14
Social System and Communication: Tigers, like most cats are solitary, however, they are not anti-social. Males not only come together with females for breeding, but will feed with or rest with females and cubs. There have actually been reports of some tigers socializing and traveling in groups. Females with cubs have also been seen coming together to share meals. Most likely, in all of these cases they are somehow related. Males will kill cubs from other males, so it is likely that the offspring in question is his own. The females most likely are mother and daughter with overlapping home ranges.
Hunting and Diet: Tigers hunt primarily between dusk and dawn, and they attack using the same method as do the lions. They stalk, chase, and attack, bringing down and killing the prey with usually a bite to the nape of the neck or the throat. The bite to the throat allows the tiger the ability to suffocate the prey bringing death relatively quickly and painlessly. Smaller animals are often killed with the bite to the nape of the neck allowing the tiger to to fracture the vertebrae and compress the spinal chord of its victim. Once killed, the tiger either drags or carries its meal into cover. The tiger's enormous strength allows it to drag an animal that would require 13 adult men to move. Tigers consume anywhere from 35 - 90 pounds of meat at one sitting, beginning at the rump of the prey. If undisturbed, they will return to the carcass for 3-6 days, feeding until it has completely consumed its kill. Because tigers are not the most successful of hunters, only killing 1 in every 10-20 attempts, it may be several days before it has its next meal. In the wild, cooperative hunting among tigers has also been observed where couples and families hunted like a pride of lions. This, however, is the exception not the rule. Unlike the other felids, man is a regular part of the tiger's diet and has earned them greatest reputation as man-eaters. The most common prey items are various species of deer and pig, but they will also take crocodiles, young elephants and rhinos, monkeys, birds, fish, leopards, bears, and even their own kind. They have also been reported to eat carrion
Status: IUCN: Endangered
Felid TAG recommendation: Tiger (Panthera tigris). The SSP for tigers supports a target population of 150-160 individuals for each of three subspecies. The Amur (formerly called the Siberian) Tiger SSP is nearly 20 years old, has functioned well with this target population, and has periodically obtained new founders from orphan situations or as F1 captive-born individuals from Europe. Its goals are not likely to change in the future. The Sumatran Tiger SSP is well under its target population, and additional spaces are readily available, especially in zoos located in warmer climates. Additional founders are periodically available from Sumatra via captive-bred individuals or wild-born tigers that must be removed from the wild. At this time, the Indochinese or Corbett's tiger also is included in the RCP (albeit present in only four zoos). Given the small founder population presently in the North American population, additional animals from range-country zoos that are unrelated to those in North America are being sought. Although still present in large but declining numbers, no space is allocated for hybrid tigers (including white tigers, since they are all inbred, crossbred, and suffer congenital birth defects). No purebred Bengal tiger are known to exist in North America because the zoos hybridized all of their stock trying to produce white tigers that could survive the inbreeding necessary to create the white coat. Due to this and a lack of space, this race will not be targeted by the Felid TAG for inclusion in its RCP. This subspecies currently is being managed in Europe under the umbrella of the EEP. No one who breeds tigers outside of the Species Survival Plan which is only for AZA accredited zoos is really breeding for conservation.
How rare is this cat ? The largest wild population of tigers are in India. According to statistics released in 2007 there are 1,200 - 1,500 tigers left on 27 wildlife reserves in 11 states in India. Tigers are no longer "burning bright" in our world's most famous tiger preserves. Read what these investigators have discovered HERE. Tiger numbers in the wild are thought to have plunged from 100,000 at the beginning of the 20th century to between 1,500 and 2,000 today. A century ago, India had some 100,000 tigers. Now, officials estimate they number about 1,200 - 1,500. The Bali, Javan, and Caspian subspecies, have become extinct in the past 70 years. The South China tiger is on the verge of extinction, with just 20 to 30 remaining in the wild. The International Species Information Service lists in captivity 1,098 worldwide in captivity with 330 being registered with ISIS in the U.S.
Fewer than 8000 of the cats remain in the wild today - a loss of more than 90,000 in the last century. Some types are particularly rare, such as the Sumatran tiger, with only about 500 in the wild and 250 in zoos. Who is to blame?
Poachers kill tigers for their bones, skin and claws (a dead cat can fetch $70,000, according to the World Wildlife Fund). Additionally, growing human populations are destroying the tigers' natural habitats. About half of the surviving cats are in India, where the government and scientists have banded together at the Panna reserve to try to protect some of the animals.

Captive Cats in Cages
One of the most common comments we hear from concerned animal lovers is that it is terrible that these animals have to spend the rest of their lives in cages. We certainly understand how they could feel like they do without knowing the complete facts, but fortunately for the cats, it is not like this at all. We do agree that it is tragic for a great cat captured from the wild to then have to spend the rest of its life in a cage. However, it is not the same thing for a cat born in captivity. The cats born in captivity which receive proper care, normally live one-third longer than their counter-parts born in the wild. This is because they are fed regularly and won't die at the hands of a poacher, hunter, or a farmer trying to protect his animals. The number one cause of death in lions in the wild is starvation, and as stated above, the tiger population has dropped from over 90,000 to under 8,000 in the last hundred years.
Therefore. we would like to borrow a segment (below) from the book "Life of Pi", written by Yann Martel, which explains this important issue far better than we could.
"In zoos, as in nature, the best times to visit are sunrise and sunset. That is when most animals come to life. They stir and leave their shelter and tiptoe to the water's edge. They show their raiments. They sing their songs. They turn to each other and perform their rites. The reward for the watching eye and the listening ear is great. I spent more hours than I can count a quiet witness to the highly mannered, manifold expressions of life that grace our planet. It is something so bright, loud, weird and delicate as to stupefy the senses.
I have heard nearly as much nonsense about zoos as I have about God and religion. Well-meaning, but misinformed people think animals in the wild are "happy" because they are "free". These people usually have a large, handsome predator in mind, a lion or a cheetah (the life of a gnu or of an aardvark is rarely exalted). They imagine this wild animal roaming about the savannah on digestive walks after eating prey that accepted its lot piously, or going for callisthenic runs to stay slim after overindulging. They imagine this animal overseeing its offspring proudly and tenderly, the whole family watching the setting of the sun from the limbs of trees with sighs of pleasure. The life of the wild animal is simple, noble and meaningful, they imagine. Then it is captured by wicked men and thrown into tiny jails. Its "happiness" is dashed. It yearns mightily for "freedom" and does all it can to escape. Being denied its "freedom" for too long, the animal becomes a shadow of itself, its spirit broken. So some people imagine.
This is not the way it is.
Animals in the wild lead lives of compulsion and necessity within an unforgiving social hierarchy in an environment where the supply of fear is high and the supply of food low and where territory must constantly be defended and parasites forever endured. What is the meaning of freedom in such a context? Animals in the wild are, in practice, free neither in space nor in time, nor in their personal relations. In theory - that is, as a simple physical possibility - an animal could pick up and go, flaunting all the social conventions and boundaries proper to its species. But such an event is less likely to happen than for a member of our own species, say a shopkeeper with all the usual tiesto family, to friends, to society, to drop everything and walk away from his life with only the spare change in his pockets and the clothes on his frame.
If a man, boldest and most intelligent of creatures, won't wander from place to place, a stranger to all, beholden to none, why would an animal, which is by temperament far more conservative? For that is what animals are, conservative, one might even say reactionary, The smallest changes can upset them. They want things to be just so, day after day, month after month. Surprises are highly disagreeable to them. You see this in their spatial relations. An animal inhabits its space, whether in a zoo or in the wild, in the same way chess pieces move about a chessboard - significantly.
There is no more happenstance, no more "freedom", involved in the whereabouts of a lizard or a bear or a deer than in the location of a knight on a chessboard. Both speak of pattern and purpose, In the wild, animals stick to the same paths for the same pressing reasons, season after season. In a zoo, if an animal is not in its normal place in its regular posture at the usual hour, it means something. It may be the reflection of nothing more than a minor change in the environment. A coiled hose left out by a keeper has made a menacing impression. A puddle has formed that bothers the animal. A ladder is making a shadow. But it could mean something more. At its worst, it could be that most dreaded thing to a zoo director, a symptom, a herald of trouble to come, a reason to inspect the dung, to cross-examine the keeper, to summon the vet. All this because a stork is not standing where it usually stands!
But let me pursue for a moment only one aspect of the question. If you went to a home, kicked down the front door, chased the people who lived there out into the street and said, "Go! You are free! Free as a bird! Go! Go!" -- do you think they would shout and dance for joy? They wouldn't. Birds are not free. The people you've just evicted would sputter, "With what right do you throw us out? This is our home. We own it. We have lived here for years. We're calling the police, you scoundrel." Don't we say, "There's no place like home"? That's certainly what animals feel. Animals are territorial. That is the key to their minds. Only a familiar territory will allow them to fulfill the two relentless imperatives, of the wild: the avoidance of enemies and the getting of food and water. A biologically sound zoo enclosure - whether cage, pit, moated island, corral, terrarium, aviary or aquarium - is just another territory, peculiar only in its size and in its proximity to human territory. That it is so much smaller than what it would be in nature stands to reason.
Territories in the wild are large not as a matter of taste but of necessity. In a zoo, we do for animals what we have done for ourselves with houses: We bring together in a small space what in the wild is spread out. Whereas before for us the cave was here, the river over there, the hunting grounds a mile that way, the lookout next to it, the berries somewhere else - all of them infested with lions, snakes, ants, leeches and poison ivy - now the river flows through taps at hand's reach and we can wash next to where we sleep, we can eat where we have cooked, and we can surround the whole with a protective wall and keep it dean and warm. A house is a compressed territory where our basic needs can be close by and safely. A sound zoo enclosure is the equivalent for an animal (with the noteworthy absence of a fireplace or the like, present in every human habitation). Finding within it all the places it needs - a lookout, a place for resting, for eating and drinking, for bathing, for grooming, etc. and finding that there is no need to go hunting, food appearing six days a week, an animal will take possession of its zoo space in the same way it would lay claim to a new space in the wild, exploring it and marking it out in the normal ways of its species, with sprays of urine perhaps.
Once this moving-in ritual is done and the animal has settled, it will not feel like a nervous tenant, and even less like a prisoner, but rather like a landholder, and it will behave in the same way within its enclosure as it would in its territory in the wild, including defending it tooth and nail should it be invaded. Such an enclosure is subjectively neither better nor worse for an animal than its condition in the wild, so long as it fulfills the animal's needs, a territory, natural or constructed, simply is, without judgment, a given, like the spots on a leopard.
One might even argue that if an animal could choose with intelligence, it would opt for living in a zoo, since the major difference between a zoo and the wild is the absence of parasites and enemies and the abundance of food in the first, and their respective abundance and scarcity in the second. Think about it yourself. Would you rather be put up at the Ritz with free room service and unlimited access to a doctor or be homeless without a soul to care for you? But animals are incapable of such discernment. Within the limits of their nature, they make do with what they have.
A good zoo is a place of carefully worked-out coincidence: exactly where an animal says to us, "stay out!" with its urine or other secretion, we say to it, "stay in!" with our barriers. Under such conditions of diplomatic peace, all animals are content and we can relax and have a look at each other. In the literature can be found legions of examples of animals that could escape but did not, or did and returned. There is the case of the chimpanzee whose cage door was left unlocked and had swung open. Increasingly anxious, the chimp began to shriek and to slam the door shut repeatedly - with a deafening clang each time - until the keeper, notified by a visitor, hurried over to remedy the situation. A herd of roe-deer in a European zoo stepped out of their corral when the gate was left open. Frightened by visitors, the deer bolted for the nearby forest, which had its own herd of wild roe-deer and could support more.
Nonetheless, the zoo roe-deer quickly returned to their corral. In another zoo a worker was walking to his work site at an early hour, carrying planks of wood, when, to his horror, a bear emerged from the morning mist, heading straight for him at a confident pace. The man dropped the planks and ran for his life. The zoo staff immediately started searching for the escaped bear. They found it back in its enclosure, having climbed down into its pit the way it had climbed out, by way of a tree that had fallen over. It was thought that the noise of the planks of wood falling to the ground had frightened it. But I don't insist.
I don't mean to defend zoos. Close them all down if you want (and let us hope that what wildlife remains can survive in what is left of the natural world). I know zoos are no longer in people's good graces. Religion faces the same problem. Certain illusions about freedom plague them both.
The Pondicherry Zoo doesn't exist any more. Its pits are filled in, the cages torn down. I explore it now in the only place left for it, my memory."
Tigers Are Becoming Extinct!
Tigers are on the brink of extinction. There are only a few thousand tigers left in the wild and the number keeps shrinking. Of the 8 species of tigers, only 5 are still in existence today.The biggest threats to the tiger's survival are poachers and loss of habitat. Poachers illegally hunt and kill the tigers for their fur, bones and other parts. The poachers get money for them on the black market. The other problem is that as the human population moves into the tiger's habitat. As the tigers move on, some of the groups of tigers get separated from others. Human populations prevent these groups from ever finding each other. As a result, these segregated groups begin inbreeding within their groups to the point where over time, the tigers give birth to unhealthy cubs with life threatening birth defects. This is known as "population fragmentation"

[edit] Jaguars
In appearance the Jaguar is often confused with the Leopard - both cats, depending to a degree on sub-species have a similar brownish/yellow base fur colour which is distinctively marked with dark rosette markings. However, the jaguar can be distinguished by the presence of small dots or irregular shapes within the larger rosette markings, a more stocky and muscular body and a shorter tail. Melanistic or black jaguars (see below) are common in certain parts of its range and are often confusingly labelled ‘Black Panthers’, a name which is also applied to black Leopards. In this melanistic form the cats are more difficult to separate, however the jaguars large head and stocky forelimbs are often a good way to differentiate between the two cats. In the wild, identification would not be an issue as the cats inhabit different continents - the jaguar is the only member of the panthera family to be found in the Americas and its is by far the biggest cat on the continent. The Jaguars range, which once spanned from the southern states of the USA down to the tip of South America, now centres on the north and central parts of the South American continent. The jaguar is predominantly a forest dweller with the highest population densities centring on the lowland rain forests of the Amazon Basin - dry woodland and grassland also serve as suitable terrain, although the cat is rarely found in areas above 8000 feet.
The overall body size and coloration of the cat often relates to its location - jaguars found in dense forested areas of the Amazon Basin are often only half the size of those found in more open terrain and it has been suggested that this can be related to the more frequent occurrence of larger prey species found in open terrain . Coloration of dense forest dwelling jaguars is often darker than those found in grassland and scrub forest - here, as with the darker coloration of rainforest leopards, the darker coats give better camouflage in the low light condition on the forest floor and offers the dark coated cat greater success in hunting and a greater chance of survival.
Unlike many other big cats, apart from man, the jaguar has no rivals - no other predator can compete with this powerful cat. The jaguars main periods of hunting activity are greatly dependant upon location - in some areas which are close to human habitation it appears that the cat is most active at night, whilst in other locations the jaguar is crepuscular and in certain cases diurnal in its hunting activity. The prey base of the jaguar is extensive, taking full advantage of the diversity and dense concentration of animal species found in the rainforest areas. In size its prey ranges from large domestic livestock such as cattle and horses (for which it has a poor reputation with local farmers), Marsh deer, Brocket deer, down through various species of Peccary, larger rodents such as Capybara, Paca and Agouti, to reptiles, monkeys and fish.
In comparison with the other cats of its size the jaguar has particularly power jaws and often kills its prey by piercing the skull with one swift bite. In the Cockscomb Basin Reserve in Belize the predominant prey species has been found to be Armadillo, who’s bony protective plates offer little defence against the power of the jaguars bite. Where possible, the cat will inhabit areas close to water - it is an expert in catching fish and will often tackle turtles and large caiman, dragging them from he water to hide the carcass in the dense undergrowth. Equally at home as a climber, although not as adept as the leopard, the jaguar will hunt monkeys in the lower branches of the large rain forest trees. In much of its range where man lives close by, the jaguar now has to compete with the human hunter and poacher who takes many of the same species as the big cat.
During the peak of its decline in the sixties and seventies, around 18,000 jaguars were killed every year for there much sought after coat. Due to environmental pressure the fashion for animal furs has declined, but the jaguar is still hunted. Today the major threat comes from deforestation which is drastically affecting the jaguars prey base as well as fragmenting the cats population into more isolated pockets. It is estimated that there are now only around 15,000 jaguars left in the wild and conservation is centring on the establishment of protected ‘National Park’ areas which may serve to reduce the decline of the jaguars natural habitat. In Belize, the government, aided by the WWF, have set aside 150 square miles of rain forest in the Cockscomb Basin Wildlife Preserve, which currently provides a protected environment for around 200 jaguars, the largest concentration of the wild cats species in the world. The WWF are also providing aid to protect some of the remaining rain forests areas of South America, which provide a refuge for the majority of the remaining jaguar population.
[edit] Cheetahs
The word "Cheetah" is derived from the Hindi word "Chita" meaning "spotted one". The Cheetah is the fastest land animal reaching speeds of 45 - 70 mph. Cheetahs have also been known to swim, although they do not like to. The Cheetah is not one of the Great Cats, because it does not have a floating Hyoid bone in its neck it can not roar, therefore it is a Lesser Cat. Cheetahs have been considered through out history to be a sleek and beautiful cat.
Cheetahs have been in captivity for over 5,000 years and were first tamed by the Sumarians. By far the Cheetah has been considered the easiest of the exotic cats to tame. The Cheetahs were used as hunting partners for sport in Asia prior to Assyrian Dynasty in Libia, during the reign of the Pharaohs. Their keen eyesight played a major role, which aided in the hunt.
Cheetahs have also been pets to many people dating back to such historical figures as Gengis Khan and Akbar the Great of India and Mogul Emperor. Akbar (1555-1600 AD) had a collection of an estimated 6,000 Cheetah, which only produced one litter each year. 25% of Cheetah in captivity will breed more than once. This along with several other studies has proven the Cheetah does not breed well in captivity.
Sub-species
The Asiatic Cheetah-Acinonyx venaticus, was hunted to near extinction by the European and Asian royalty. Their beautiful pelt was a symbol of wealth and was worn proudly. Although the pelt was not coveted as that of the Leopard, these cats were almost completely destroyed. Today only an estimated 200 of this sub-species exist in small isolated groups scattered throughout Eastern Iran.
The King Cheetah was once considered it own species, however now it has been proven to be nothing more than a genetic mutation. King Cheetah originated from Central Africa, where they were used for hunting. These Cheetah were part of a breeding program to acquire genetic mutations, such as fur patterns, size, and rare and unusual color forms, with no regard to the genetic integrity of the species. This African Cheetah can only be found naturally in Zimbabwe and South Africa Transvaal Province providing that both of the parents carry the recessive gene.
Appearance
The Cheetah is a tall and elegant cat in appearance. Large chest, narrow waist, long thin legs, and a slim well muscled build this animal was definitely made for speed. The Cheetahs coat varies from a tawny to golden tone covered in a pattern of solid black spots averaging .75"-1.5" in diameter. The Cheetahs beautiful pelt became more protected in 1970, when the fur trade regulations were strengthened. The fur is coarse to the touch not silky as it appears. The Cheetahs long thick tail has spots, which turn into rings and at the end is tipped with white. The throat and abdomen are a creamy white in color. The Cheetah has a small head with high set eyes and short rounded ears tipped with white on the back. The most well known characteristic is however the distinct black "tear mark", which runs from the inside corner of the eye down to the corner of the mouth.
Cubs are born with a mantle of fur running from the back of the neck down to the rump. This clever disguise aids in camouflaging the kittens in the high grass while they are following their mother. This mane like feature begins to disappear at the age of 3 months, but still remains visible at 2 years of age. The fur color of a newborn cub is medium gray, which gradually evolves into the adult colors by the age of 4 months.
The King Cheetah has a fur pattern mutation, which turned the small rounded spots into large connected black patches. This mutation is caused from a lack of genetic diversity.
Size
The Cheetah weighs an average of 83-145 lbs., making them about the same weight as that of a leopard. The length of a Cheetah is approximately 70"-86" from the tip of the nose to the end of the tail. Being an extremely tall cat the Cheetah stands at an average of 32" tall.
Newborn cubs weigh an average of 5.25-10.5 oz. The body length of a cub is approximately 11.8", which may vary.
Habitat
The Cheetah prefers to live in open grasslands, savannas, dense vegetation, and sometimes even mountainous terrain. The open land of grasslands and semi-desert better accommodates the Cheetahs way of hunting, which is running as opposed to the stalk and pounce method. Namibia is home to the largest population of Cheetah at about 2,500 cats. Due to the continuous growth of farmland and expanding development 95% of the Namibian Cheetah live on cultivated farmland.
Distribution
The Cheetah was once widely distributed throughout Africa, the Arabian Peninsula, Asia Minor, and even East of India. Fossils were recorded to be found from China, Northern India, Southern Europe, and as far as the Western United States. Sadly now the species is burning out and can be found sparsely scattered amongst Namibia, Kenya, Asia, as well as a handful of other small countries.
Reproduction
The Cheetah above all else is the most reproductive cat. Why then is it so endangered? The answer is two-fold. Cheetah cubs often fall prey to Lions, Jackals, Birds of Prey, and Hyenas, as the mother must leave them behind while hunting for food. Even if the mother was near, she could not fend off an animal as large as a Lion or Hyena, the Cheetah was built for running not fighting. 90% of Cheetahs born die with in the first 3 months, 50% of which are destroyed by predators. The other 40% fall victim to lack of genetic diversity. This is the second reason for their inability to survive. This genetic peril is responsible for weak and underdeveloped immune systems. Disease and illness attack a weak immune system, which in turn causes death. Most cubs do not even make it past 1 month old when this is the case.
After a gestation period of 90-95 days a female Cheetah will give birth to a litter of 3-5 cubs. The largest litter recorded in captivity was 8. The male Cheetah does not participate in the rearing of the cubs. The mother may leave the cubs for as long as 48 hours in order to hunt for enough food to sustain her in a lactating state. If the food supply is too scarce the mother may abandon the cubs, so as to maintain her way of life. Also if the litter is lost with in the first few weeks the female will come into estrus in the next few days. If this is not the case the mother will return and move the cubs from one location to another to better hide the smell of her young from predators. Sometimes the mother will even wait until night falls to return to her cubs, so that she is not as easily followed.
Cubs
The cubs are usually weaned at 6-8 weeks and will then leave the den and follow the mother from then on. If a young cub loses its original family, due to some great misfortune, it will find another family and join them despite the ill will from the new mother and being out cast by the new brothers and sisters. At 5 months old, the cubs are playing with one another, sharpening their stalking, chasing, and wrestling skills in a playful manner. At 6 months the mother Cheetah will fetch live prey injuring it and then giving it to the cubs so they may practice the art of the kill. At 8 months the cubs are chasing inappropriately large prey such as Giraffes. A Cheetah will not be a very skilled and efficient hunter until about 3 years of age. Cheetah cubs kill less than 10% of the prey, which the family feeds on. At 15-24 months the cubs will leave the mother, but may stay together for several more months. Young females will leave her brothers when they reach sexual maturity. Young males will travel far from parents and will lay claim to a territory as large as 300-800 square miles. Young females will stay closer to home and may even overlap territory with the mother.
Social System
Female Cheetahs are solitary animals except when rearing a litter. Mothers with cubs will usually stay with in close proximity of one another. Females only come in contact with other Cheetahs in order to mate.
Males on the other hand will sometimes form coalitions of 2-3 in order to defend more land. These coalitions are mostly formed between brothers, but sometimes include outsiders. 30 % of coalitions are unrelated. Males are not territorial towards each other, but are in fact towards other males or coalitions. Due to coalitions fighting against one another the ratio has dropped to one male for every two females.
Communication
Cheetahs communicate in many different ways. Some of these are through vocalizations such as purrs, bleats, barks, growls, hisses, and a high pitched chirping sound. Another way to communicate is through marking. A Cheetah will mark their territory by urinating or by cheek and chin rubbing. Saliva that is secreted contains the same chemical information about the animals, as does the urine. Cheetahs will mark territory so that they can better avoid one another.
Hunting
The Cheetah is the fastest land animal, reaching a top speed of 70 mph! The Cheetah however can only run for short sprints of up to 300 yards. These sprints will usually last for 20 seconds, but rarely ever reach a full minute. Non-retractable claws and tough pads on their feet closely resemble that of a dog. These features offer better traction to get to those high speeds. A long heavy tail acts as a rudder for making those sharp turns while in pursuit. The Cheetah’s long fluid body is set over extremely light bones, this accompanied with large nasal passages, and oversized lungs, liver, heart and adrenals enable rapid physical response. This response is imperative to accommodate the Cheetah’s way of hunting. A strong spring-like spine gives added reach to the Cheetah’s long legs. A stride is the measured distance between successive imprints of the same paw. With the added reach given by the spine 1 stride can stretch as far as 7-8 meters. The Cheetah averages 4 strides per second or 1 stride per .28 seconds as the horse averages 1 stride per.44 seconds and can reach top speeds of 43 mph. The Cheetah can out run the horse going from 0-45 mph in 2 seconds flat, though this will not very last very long. The horse would inevitably win in the long run.
Cheetahs are equipped with several special features that are crucial in successful and efficient hunting. Binocular vision is a very important asset since Cheetahs rely on sight to hunt as opposed to scent. The retinal fovea of the eye is of an elongated shape, giving a sharp wide-angle view. This aspect of the eye is also adapted for speed. The dark "tear marks" on the Cheetahs face reduce glare from the bright sun also and aid in excellent vision. The Cheetahs will perch upon a fallen tree or rocky ledge to scope out the surroundings and potential prey. The Cheetah is also a very vocal animal. With the ability to mimic the calls of some birds, by displaying a high pitched chirping sound. When a bird falls for this deceiving call it will also fall prey to the sly Cheetah.
The Cheetah is a carnivorous animal and a diurnal hunter, which means it hunts during the day usually early morning and late afternoon. Cheetahs are solitary hunters except when living in a coalition. When this is the case they will hunt in groups so that they can take down larger prey. Unlike the common misconception, the Cheetah will pick out animals that have strayed from the herd as a target, not necessarily the weak or old. After chasing down and catching the prey, the Cheetah suffocates larger animals with a bite to the jugular and holding for as long as 15-25 minutes. Smaller animals are killed with a quick bite to the head usually killing them instantly. By this time the Cheetah is so tired from the chase that it must wait for as long as a half hour before consuming its meal, and could not fend off other predators, who might want to steal the Cheetah’s dinner. The Cheetah’s resting heart rate is approximately 120-170 beats per minute, while it’s heart rate after a chase is 200-250 beats per minute. The Cheetah’s resting breaths vary from 20-30 per minute depending on whether the Cheetah is in direct sunlight or in the shade, after a chase the Cheetah’s breaths per minute are 150-200! When done resting the Cheetah will quickly eat, as they can not defend their food from other predators for this reason they will not bury the food and come back for another meal. Half of the Cheetah’s hunts are successful, the other half are hard life lessons.
Diet
The Cheetah’s diet consists of a wide range of prey from steenbok, rabbits, wildebeest calves, duikers, kudu, and impala to springbok, hartebeest, oryx, roan, sable, birds and warthog. The most preferred and most hunted by the cheetah however is the Thompson’s Gazelle. Something about these graceful animals just makes a Cheetah’s tummy roar! Cheetahs consume an average of 6-8 lbs. of food each day, and in some cases may go as long as 4-10 days with out water.
Extinction Is Forever
The Cheetah is considered Endangered in Appendix 1 to the Conservation Of International Trade in Endangered Species (CITES). Humans have been proven to be the most feared predator by the Cheetah. Living space and adequate food supply is being robbed from these innocent creatures. Farmland is expanding into the Cheetah’s natural environment leaving the Cheetah to move on or be killed by paranoid farmers. A law was passed authorizing ranchers to shoot on sight any Cheetahs due to an alleged imposing threat to livestock. In 1980 alone ranchers killed a reported 6,829 Cheetahs. Poachers also pose a threat to the Cheetah, whose pelt was coveted and was doomed to become a fad. In the 1960’s 1,500 Cheetah pelts each year were imported into the United States due to an accessory fad. It was considered hip and a sign of wealth to wear a Cheetah fur. The number of Cheetahs has consistently dropped every year since 1900. In 1900 there were over 100,000 Cheetahs, in 1970 the numbers plummeted to 20,000-25,000 Cheetahs, and to this day there are only 10,000-15,000 Cheetahs. One tenth of which live in captivity. Due to the unavailability of land and food and the dangerous threat brought on by ranchers and poachers the Cheetah’s lifespan in the wild is 4-6 years, where as in captivity the Cheetah will live to 10-15 years old.
Felid TAG 2003 recommendation: Cheetah (Acinonyx jubatus). After determining correct husbandry techniques for reproduction, cheetah populations have increased without the need for additional founders. Unfortunately, recent importations usually sought specimens of the "king" or "rex" color morpho-types. Some of these individuals have been imported without regard to genetic need and often related to individuals already in North America. The target population for cheetahs in North America is 300 individuals. Since disease and stress are such prevalent causes for cheetah mortality, many of the new breedings will take place off zoo properties.
How rare is this cat ? The International Species Information Service lists 680 in zoos worldwide, with 227 being in the U.S.
[edit] Ring Tailed Lemur
Lemurs are primates found only on the African island of Madagascar and some tiny neighboring islands. Because of its geographic isolation, Madagascar is home to many amazing animals found nowhere else on Earth. Lemurs may have floated there eons ago on "rafts" of vegetation and evolved in isolation over countless centuries.
Ring-tailed lemurs are unmistakable because of their long, vividly striped, black-and-white tail. They are familiar residents of many zoos.
Lemurs use their hands and feet to move nimbly through the trees, but cannot grip with their tails as some of their primate cousins do. Ring-tailed lemurs also spend a lot of time on the ground, which is unusual among lemur species. They forage for fruit, which makes up the greater part of their diet, but also eat leaves, flowers, tree bark, and sap.
Ring-tailed lemurs are about the size of a Cottage cat. They are about 17 inches long and have a tail that is about 24 inches long. They weigh about 7 pounds.
These are sociable animals, traveling in groups of anywhere from 3 to 25 animals. The females are dominant, which allows them first access to food and the choice of whom to mate with. They live in arid and open areas and forests and spend much of their time on the ground. Their diet consists of fruit, leaves, flowers, herbs and other plants. They will sometimes eat insects and small vertebrates. Lemurs can live up to 25 years.
Ring-tailed females are able to give birth at 3 years of age in the wild and as early as 18 months when in captivity. They produce offspring annually after that. In the wild, mating begins in mid-April. The babies are born in August and September. One offspring is usual, but twins are fairly common. Infants are weaned at 5 - 6 months of age.
Ring-tails use grooming to form social bonds within the group. Like all prosimians, ringtails groom in a rather unique way. They have 6 lower teeth that stick straight out from their jaw, making a sort of comb that the animals use to groom their fur and the fur of other group members.
Ring-tailed lemurs are found in south and southwestern Madagascar. The forests they live in are in danger of being converted to farmland, overgrazed by livestock and used for other purposes. The ring-tail is also hunted for food in some areas and also kept as a pet. Luckily these animals are protected in certain areas and breed very well in captivity.
Just like cats, ring-tailed lemurs mark their territory. They have scent glands on their wrists and chests that they use to mark their paths. When ring-tailed troops travel throughout their home range, they keep their tails raised in the air, like flags, to keep group members together.
The little Ring-tailed Lemur shown at top comes from Aurora World. It is 12 inches long. Check the Gift Shop to see if there are any Lemurs in stock.
PHYSICAL CHARACTERISTICS:
The Ring-tailed lemur, Lemur catta, is one of twenty-two species of lemurs. They share a common ancestry with Africa's monkeys and apes, but were isolated from those species probably 50 million years ago when Madagascar separated from the African continent.
All lemur species today are endangered due to the rapid destruction of their forest habitat for agricultural development, cattle grazing, and human settlement.
They, like their primate cousinsize="3"s the monkeys and apes, have binocular forward vision, but must turn their heads to see ahead because their eyes have limited movement in the socket. This gives them a wide-eyed, staring aspect that sometimes startles viewers.
The word Lemur comes from old Latin, and refers to ghosts or spirits. The staring eyes, haunting sounds, and nocturnal ways of the lemur inspired early observers to think of them as ghosts or forest spirits.
The Ring-tailed lemur's coat is black gray, the limbs and belly lighter, and the extremities white. Their are rings about the eyes, the muzzle is black, the tail is banded black and white.
DISTRIBUTION and HABITAT:
Lemurs are found only on the east African island of Madagascar. They live in the dry woodland districts with a seven to eight month dry season.
BEHAVIOR:
Most lemur species are arboreal. But the Ring-tailed is different in that it frequently uses the ground for travel, more than any of the other lemurs. It is diurnal and gregarious, living in groups of 5-30. Females are generally dominant to males.
Its long, bushy, black-and-white banded tail is used by the species as a visual signal. In aggressive encounters, the Ring-tail will wave its scent-covered tail in the direction of a rival. Loud calls alert other members of the social group to danger and help to maintain comfortable spacing between groups.
Watch the feeding of the ring-tailed lemurs!
(click if you don't see the movie)
Ring-tailed lemurs purr and mew like house cats. It loves to sunbathe with legs and arms spread wide. Living in an arid habitat, it quenches its thirst with juicy fruits. Sitting on its haunches holding fruit in its hands, a lemur delicately bites off pieces with its back teeth so the juice runs into its mouth and not on its fur.
They communicate with short grunting sounds as a contact call within the troop, sometimes followed with a quick bark.
DIET:
Lemurs are generally herbivorous. Their diets consisting mainly of leaves, fruits, and berries -- although they occasionally take bird eggs, small mammals, and insects.
REPRODUCTION and GROWTH:
After a gestation period of about 135 days, a single offspring is born. Occasionally they may have twins or even triplets. The young are grayish with a thin coat of hair. The entire group helps care for and play with the young. Young lemurs first begin to climb at about three weeks, and are usually independent by six months. They are sexually mature and fully grown at 11/2 years. In captivity lemurs have lived for 20-27 years.
The Ring-tailed lemur has a very distinctive bushy tail with alternating bands of black and white rings. It also has a black, pointed muzzle, which is typical among the various species of lemur.
Lemurs are vegetarian, consuming leaves and fruit.
Lemurs are found solely on the island of Madagascar, an island off of southeast Africa. They prefer more open areas in the south and typically walk on the ground or on large limbs in the trees. This differentiates them from other lemur species, which prefer forested areas and travel mostly in trees.
Ring-tailed lemurs live in groups of five to thirty members. They have distinct hierarchies that are enforced by frequent, aggressive confrontations between members. Females, who stay in the group for their entire lives, dominate the group. Males have a social structure that undergoes great upheaval during mating season. They tend to change groups at least once during their lifetime.
Ring-tailed lemurs have a reflective layer in the back of their eyes similar to that of cats. This allows them to have very good vision at night. The sense of smell is important to the lemur. The Ring-tailed lemur has a highly scented tail, which is used to warn other Ring-tailed lemurs.
Ringtailed lemurs (Lemur catta) are the most intensely studied of all the lemurs: they are also the most easily recognizable lemur and the most common in captivity. They are also the most terrestrial of all the lemurs. Although widely distributed throughout the dry forests of southwestern Madagascar (some of the hottest, driest and least hospitable forests in the country), they exist in only a few protected areas.
Unfortunately, the sparse, level forests inhabited by ringtails are easily felled by even the most primitive of tools. Hence ringtailed habitat is shrinking at an alarming rate. In fact, satellite images suggest that ringtailed lemur habitat is vanishing at an even greater rate than forest habitat in other parts of Madagascar.
Male ringtails are equipped with scent glands on their wrists which are used in "stink fighting" with a rival male. Here, two males stand facing each other a few feet apart and, repeatedly drawing their tails through these glands, they proceed to wave the tails over their heads, all the while staring in a hostile fashion at their rival. Eventually, one of the males will break down and run away. During breeding season in the N.C. autumn, competition between the normally "laid back" males becomes fierce as they fight for the right to breed. Like the other diurnal lemurs, ringtails are seasonal breeders, and their matings and births (which occur in the fall and spring) are highly synchronized. All infants in a large troop may be born in a matter of days.
Due to the large number of L. catta in captivity, the ringtailed SSP calls for only a few breeding pairs of animals each year so that precious captive breeding space can be occupied by the rarer species of lemurs.

[edit] Polar Bears
Bear Status Report Polar bears are a potentially endangered species living in the circumpolar north. They are animals which know no boundaries. They pad across the ice from Russia to Alaska, from Canada to Greenland and onto Norway's Svalbard archipelago. No adequate census exists on which to base a worldwide population estimate, but biologists use a working figure of 20,000 to 25,000 bears with about sixty percent of those living in Canada.
In areas where long-term studies are available, populations are showing signs of stress due to shrinking sea ice. Canada's Western Hudson Bay population has dropped 22% since the early 1980s. The declines have been directly linked to an earlier ice break-up on Hudson Bay. A long-term study of the Southern Beaufort Sea population, which spans the northern coast of Alaska and western Canada, has revealed a decline in cub survival rates and in the weight and skull size of adult males. Such declines were observed in Western Hudson Bay bears prior to the population drop there. Another population listed as declining is Baffin Bay. According to the most recent report from the Polar Bear Specialist Group, the harvest levels from Nunavut when combined with those from Greenland (which were thought to be much lower than they actually are) has resulted in this shared population being in a non-sustainable harvest situation, meaning the population is at great risk of a serious decline. The harvest is thought to be several times above what is sustainable.
The IUCN Polar Bear Specialist Group reclassified the polar bear as a vulnerable species on the IUCN's Red List of Endangered Species at their most recent meeting (Seattle, 2005). They reported that of the 19 subpopulations of polar bears, five are declining, five are stable, two are increasing, and seven have insufficient data on which to base a decision. In the U.S., the U.S. Fish and Wildlife has proposed that the polar bear be listed as a Threatened Species under the Endangered Species Act. The agency will make a final decision in January 2008. Canada and Russia list the polar bear as a "species of concern."
Some Native communities in Canada have been reporting increasing numbers of polar bears on land. Traditional hunters believe this indicates an increased population, although the increased presence on land may, in fact, be related to shrinking sea ice and changes in the bears' distribution patterns. Data is needed to understand the change. The U.S. Fish and Wildlife Service states, "In the declining polar bear population of Canada's Western Hudson Bay, extensive scientific studies have indicated that the increased observation of bears on land is a result of changing distribution patterns and a result of changes in the accessibility of sea ice habitat."
Climate change is the main threat to polar bears today. A diminishing ice pack directly affects polar bears, as sea ice is the platform from which they hunt seals. Although the Arctic has experienced warm periods before, the present shrinking of the Arctic's sea ice is rapid and unprecedented.
In the 1960s and 1970s, hunting was the major threat to the bears. At the time, polar bears were under such severe survival pressure from hunters that a landmark international accord was reached, despite the tensions and suspicions of the Cold War. The International Agreement on the Conservation of Polar Bears was signed in Oslo, November 15, 1973 by the five nations with polar bear populations: Canada, Denmark (Greenland, Norway, the U.S., and the former U.S.S.R.
The polar bear nations agreed to prohibit random, unregulated sport hunting of polar bears and to outlaw hunting the bears from aircraft and icebreakers as had been common practice. The agreement also obliged each nation to protect polar bear denning areas and migration patterns and to conduct research relating to the conservation and management of polar bears. Finally, the nations agreed to share their polar bear research findings with each other. Member scientists of the Polar Bear Specialist Group now meet every three to four years under the auspices of the IUCN World Conservation Union to coordinate their research on polar bears throughout the Arctic.
The Oslo agreement was one of the first and most successful international conservation measures enacted in the 20th century. Its legacy continues today, with member scientists from each nation continuing to work together in face new threats to the bears including climate change, pollution, industrial activities, and poaching.
