What are the characteristics of a tiger's habits and lifestyle?

Tigers are generally solitary, have no fixed den, and mostly roam the mountain forests in search of food. They usually prey on wild deer, wild sheep, wild oxen, wild boar, red deer, sambar deer, roe deer, musk deer, muntjac and other hoofed animals, and occasionally prey on wild birds; in autumn they eat berries and large insects. They generally rest in hiding during the day and come out to be active at night. They can swim, but are not good at climbing trees.

1. Tigers prefer to be solitary; only during the mating period and the nursing period do male and female tigers, or a mother tiger and her cubs, live together. Adult tigers, especially siblings from the same litter, are quite likely to cooperate with one another for a period of time (whether this is long-term is unknown) and share their catch.

2. Each tiger has its own territory. When patrolling its territory, it will raise its tail and spray strongly scented secretions and urine onto tree trunks or into bushes; sometimes it also scratches marks into tree trunks with its sharp claws, or rolls on the ground to leave tiger hair behind, in order to define its sphere of influence. If there is an intruder, the male tiger usually follows a policy of killing it.

3. Tigers have no fixed den and mostly roam the mountain forests in search of food. They usually prey on large mammals, including various hoofed animals such as wild deer, wild sheep, wild oxen, wild boar, red deer, sambar deer, roe deer, musk deer and muntjac. Sometimes they also catch various small animals, such as birds, monkeys and fish. To aid digestion, they occasionally nibble on grass. When extremely hungry, they will also prey on human livestock, and even eat people.

4. Tigers generally rest during the day and come out to be active at night. They do not like hot weather, because they lack sweat glands, so in summer they always look for shade under trees to hide, or soak and play in ponds; however, their tree-climbing ability is far inferior to their swimming skill.
