Life style and characteristics of tigers

behaviour

There are no fixed nests, and most of them wander in the mountains for food. Can swim, can't climb trees. Due to the development of forest areas and the surge of population, remote areas have developed into villages and towns in the past, and tigers often forage near forest settlements. Tigers are more active at dusk, more dormant during the day and rarely come out without being disturbed. Tigers have a wide range of activities, and their daily foraging activities can reach dozens of kilometers in the north;

Tigers don't like hot weather because they lack sweat glands. When summer comes, they always look around for shade. Because of their superb swimming skills, they love swimming very much, and tigers in hot areas especially like to bathe and play in ponds. However, their tree climbing skills are far less than swimming skills, which is estimated to be caused by their large size and weight. ?

In Xishuangbanna, south of China, there is more food, so the moving distance is shorter. It's basically Nocturnal Animals, but in some protected areas far away from human beings, these guys also go out for a walk during the day. Tigers living in the cold north sometimes have to go out to hunt during the day. ?

Looking for food

When the tiger meets its prey, it will crouch down, seek cover, and slowly dive in. When the prey comes within the attack distance, it will suddenly jump out and attack its back to avoid being hurt by the resistance of the prey. The tiger will first scratch its prey's back with its claws, drag it to the ground, and then bite its throat with sharp canine teeth to suffocate it until its prey dies. This attack mode is also the most typical attack mode of cats. The tiger's special attack way is to bite off the other person's spine, which is more common in big cats. ?

The tiger's most complex attack weapon is its thick teeth and retractable claws. Predation is extremely fierce, rapid and decisive, and the principle is to consume the least energy to get as much as possible. But when hunting wild animals, if you are not sure enough, you will never do it. Tigers have no natural enemies in Asia. Because of the thick meat pad on his feet, the tiger is quiet and alert when he moves. When it walks in the snow, its hind foot can accurately step on the footprints of its front foot. ?

Eating habits

They usually prey on large mammals, including hoofed animals such as wild deer, wild sheep, bison, wild boar, red deer, water deer, deer, musk deer, muntjac, etc., occasionally prey on wild birds, and also eat berries and large insects in autumn. The amount of meat eaten each time is 17-22 kg, and the big one can reach 30 kg per meal, and then you don't have to eat meat for 6 days.

Sometimes they catch all kinds of small animals, such as birds, monkeys, fish and so on. To help digestion, they occasionally eat grass. Sometimes hungry tigers will prey on human livestock and even kill people (human-eating tigers are often poor guys who are old, weak, sick and unable to deal with healthy animals, and this tragedy usually only happens after humans enter the tiger's territory), so they are hated by some humans. If the food can't be eaten, they will also hide the rest, usually in a place not far from the water source, and come back to eat in a few days. ?

field

Tigers have a large range of activities, generally 100-400 square kilometers, and the largest can reach more than 900 square kilometers. In the north, the range of foraging activities can reach tens of kilometers, while in Xishuangbanna in the south, the distance is short because of more food. The Siberian tiger lives in the area with the least prey and needs the largest range of activities. The female tiger needs 400 square kilometers, and the male tiger needs 1000 square kilometers. The range of activities of Bengal tiger in India is only 10 square kilometers, while that of male tiger is only 30 square kilometers. The range of the South China tiger is larger than that of the Bengal tiger but smaller than that of the Northeast tiger, which is conservatively estimated as 100 square kilometers. ?

Tigers often act alone, and only in the breeding season do males and females live together. Every tiger has its own territory. When the male tiger and the female tiger patrol the territory, they will raise their tails and spray secretions and urine with strong smell on tree trunks or bushes to delimit their sphere of influence. Sometimes they scratch marks on the trunk with sharp claws, or roll on the ground, leaving tiger hair to define their sphere of influence.

Although tigers live alone and have their own territory, male tigers may often stay with their spouses and children. Adult tigers, especially brothers and sisters, are likely to cooperate with each other for a period of time (whether long-term or not) and enjoy the harvest.

A male tiger may have more than one female tiger's territory, but the territories between the female tigers may not overlap. The male tiger strictly defends his territory. The territory is too large, and it is inevitable that some people will want to take advantage. In the face of intruders, male tigers usually pursue a killing policy, which can also reduce their future competitors. A tigress is generally not so boring. Even if their neighbor dies, they may not necessarily explore this territory.

Extended data:

Tiger brain capacity

According to Xinhua News Agency, London (Reporter Huang Kun), both tigers and lions are kings of beasts, but which of them has more brains? A new study in Britain shows that tigers have bigger brains than lions and should be smarter and braver.

Researchers at Oxford University in England recently reported that they have detected a large number of skull samples of tigers, lions, African leopards and leopards. The results show that although the maximum length of the lion's skull is larger than that of the tiger, its brain capacity is smaller than that of the tiger. Even the smaller female Balihu (who once lived in Bali, Indonesia and died out in the last century) has a larger brain capacity than the large African lion. In addition, judging from the proportion of brain volume in the whole cranial cavity, lions, African leopards and leopards are almost the same, while the proportion of tigers is about 16% higher than them.

According to the press release issued by Oxford University, lions are social animals, while tigers usually act alone. There was a theory that social interaction brought by social activities was helpful to brain development, but now it seems that this view is open to question. Since these big cats originated from the same ancestor, further research will help to understand the reasons why their brains evolved differently. ?
