Physical Description of Tigers
Do I really need to describe a tiger for you? The coat is clearly ‘tiger-striped,’ with vertical black stripes on a reddish-orange fur. The face is also striped, sometimes with white patches around the eyes. The underlying fur is generally reddish-orange but can be quite light-colored and almost white in some animals, while the belly and underside are a lighter color in most animals. The tail also carries the black stripes.
Tigers are the largest of all cat species. Like a lot of species, the island versions are somewhat smaller. The now-extinct Javan and Balian tigers were relatively small, and the smallest remaining subspecies is the Sumatran tiger. The Siberian tiger, on the other hand, is the largest, as larger bodies are somewhat more effective at keeping warm in colder climates. The Bengal tiger – the one we all think of when we think of tigers – is approximately 2 m long and stands about 1 m at the shoulder with a tail that can reach another meter. They weigh up to 250 kg, though the female is considerably lighter than the male, often not reaching more than 150 kg. There is also a considerable difference in the size of the Bengal tiger subspecies, ranging from lightweights in Bangladesh to heavyweights in Nepal.
Today, the weights of some Bengal tigers rival that of the Siberian subspecies, possibly because the heavier, larger, and more impressive were overhunted. We can imagine that the male population is returning to its preferred size, given today’s strict controls on hunting.
Also, the average weight of Siberian tigers is now less than previously, and they are not as massive as historic populations were.
Distribution and Habitat of Tigers
Tigers have a pretty extensive range as far as cats go in the modern world. They range from Siberia to tropical Indonesia and throughout the Indian subcontinent. The range was once even larger, spreading into Iran and Turkey and onto numerous Indonesian islands. Today, the range, while still extensive, is not widely covered in tigers. They are mostly gone from China and South East Asia. Few remain in Indonesia, restricted to the Island of Sumatra. The numbers in Manchuria and the Far East are limited, and the populations in India are very fragmented.
What helped the tiger spread over such a large range was its ability to live in a variety of different habitats. The tiger does like long grasses and cover for hunting, but it is adaptable and can live in all forest types and even in areas with minimal vegetation. It just needs enough for some cover while hunting.
The tiger lives from the sea level in places like Bangladesh right up to 4000 m in the Himalayas, from areas with tropical rainforest to the taiga forests of Siberia. These diverse lands have obviously equally diverse landscapes and habitats. The birch forests of the north and the tropical rainforests of the south are significantly different, and the life and numbers of tigers reflect this.
Best National Parks to see Tigers
The tiger can commonly be seen in multiple National Parks. Ranthambore and Bandhavgarh are best known outside of India. Kanha and Pench are quite nice, as they also serve as the background of Kipling’s Jungle Book. Further south Tadoba, Nagarhole and Bandipur have a slightly lower number of sightings but still offer great opportunities, and Kaziranga National Parks, despite being mainly known for its rhinoceros population, offers food chances to see Tigers. There are quite a number of other tiger reserves in India. Outside of India, it is difficult to see one in the wild.
Tiger behavior
On leaving their mothers, tigers become solitary animals. Tiger cubs can stay with their mothers for two years. Males stick to themselves, though they are sometimes known to interact with their cubs within their home territory. This is relatively rare.
While tigers are somewhat nocturnal, they are also visible and active during the day. Quite often in tiger reserves, they will be seen wandering along the main tracks, but when hunting they prefer the undergrowth and dense jungle that, along with their stripes, provides plenty of camouflage.
Despite being a massive creature, the cats are quite capable of moving stealthily through the bush. They are ambush hunters and so spend a lot of time stalking and only make an attack when they are close enough, though, in the case of a tiger, this is a lot further than the case with other cats. Their ability to jump long distances is indeed impressive.
Territories are generally well guarded against interlopers, but tigers are also known to have overlapping territories in areas where the prey concentration makes this necessary.
The territory of a tiger is marked by scent. However, they also leave scratch markings on trees as well to indicate that they are in charge of the territory. It is noticeable when you see a tiger that responds to a scent marking. He generally wrinkles his nose and lets his tongue hang out. This is to help smell the scent better and understand the marking.
Growls and roars are common forms of communication up close. The roar is not as impressive as that of a lion. However, it is designed to display the tiger’s size and his dominance as well as to let others know where he is. Essentially, it is a warning.
What do Tigers eat?
The tiger is at the top of the food chain, and nothing will get in its way. It will eat almost anything. Mostly though, it hunts deer that is slightly smaller (at least lighter) than itself. Sambar, spotted deer and barking deer are all normal. Even elephants (young) and rhinoceros are on the menu. However, this is only in opportunistic cases, such as when the prey is sick. In times of scarcity, anything smaller will also be eaten, such as the Indian wild chicken or even rodents.
Hunting is not commonly observed in tigers because they mostly hunt at night and in the dense brush. As stealth hunters, they maximize the cover available and only leap at the last moment. This means that successful hunts are only briefly visible to any observer. The prey is quickly dragged back into the dense undergrowth. Larger kills will be eaten over a number of days.
Mating and Parental care of Tigers
Tigers are solitary animals. It is standard among cat species. The males and females live separate lives except during mating season. When we say solitary, we are referring to adults. Kittens, or as they are known in the case of tigers – cubs – obviously live with their mother. This can last for up to three years but is generally two. Along with lions, this is the longest time that cubs stay with their mother.
The family unit stays together from birth until the cubs have learned enough to hunt successfully on their own. For the first couple of months, tiger cubs are kept in a den, but when they start to eat the prey their mother brings back, they start to explore. It takes a long time, though, before they are big enough and strong enough to hunt for themselves. From six months on, the cubs are fully weaned, and they start to follow their mother during the hunt.
Tigers generally have 2 or 3 cubs in a litter, and the mother’s hunting needs to increase significantly once they are eating solid food. As adults are solitary, the males do not help in the raising of cubs. Even the father can be a threat.
However, more recently, it has been seen in two tiger Reserves in India, Ranthambore and Panna, that a male has been ‘caring’ for his offspring after their mother died. While the fathers haven’t been teaching the cubs to hunt, they have both made uneaten kills in the cubs’ home range. This does suggest that paternal care exists, though it is not exactly clear evidence.
Who preys on Tigers?
The only threats to tigers are humans and, well, other bigger tigers. No other animal is silly enough to attack them. There isn’t a lot of tiger-on-tiger violence except when it comes to defending territories. Some males will attack cubs to bring the female back into oestrus, but it isn’t as common as in other species.
How long do Tigers live?
Tigers can live up to about ten years. However, the vast majority of cats die young. Significant numbers don’t survive to maturity due to the harshness of jungle life. However, the biggest problem lies in 2-3 year olds leaving their mothers and trying to define their own territories.
Over the majority of the tiger’s range, territories are limited by the encroachment of human settlements. The majority of tiger reserves in India are now ‘full’ and have no space left for the young to establish a new territory. There is, quite simply, a lack of suitable habitat for young tigers to move into.
This leads to the young tigers coming into close contact with humans, and unfortunately, tiger-human conflict ensues. Most often, this is to the detriment of the tiger.
Tigers and their ecosystem
Tigers are the apex predator in their ecosystems and are extremely important in the balance of nature.
Impact of Tigers on the human economy
Tiger skins used to have great economic value. However, that trade is fortunately disappearing, though there is still a black market for it. The illegal trade in body parts for medicine is, unfortunately, still economically viable.
Tigers do have economic value for tourism. A lot of the tiger reserves in India are quite a distance from centers of wealth and employment. The tourists the tigers attract bring with them economic value for the rural residents.
Tigers do have some adverse effects on humans. They eat us. However, this is extremely rare and is generally only because we have forced the tigers out of their habitat or because conservation successes mean that younger tigers are taking over the territories of older, weaker tigers, who are then forced to try and survive outside of overcrowded tiger reserves.
Conservation status and human impact on Tigers
The tiger is endangered, according to the IUCN. However, this doesn’t take into account the very perilous state of certain subspecies. Siberian tigers are critically endangered, and so is the Sumatran. Poaching and habitat loss are mostly to blame, the same as for most animals. The Bengal tiger in India is seeing something of a recovery in its numbers due to conservation successes, but the fragmented populations mean there is no room for complacency.
Other important information about Tigers
Tigers have numerous subspecies.
The most important are the Caspian tiger, which used to be in Europe but is extinct, the Javan tiger, now also extinct, and the Sumatran tiger, which is extremely endangered. The Siberian tiger living in Manchuria and Siberia is also critically endangered. The Bengal tiger, that of India, is still endangered, but the population is recovering well from a low point in the late 20th Century.
