Tigers are typical mountain animals, which can survive well from tropical rain forests and evergreen broad-leaved forests in the south to deciduous broad-leaved forests and mixed coniferous and broad-leaved forests in the north. In the northeast of China, it often appears in mountainous areas, such as ridges, bushes, rock or gravel ponds, etc. In order to hunt.

Tigers often act alone, and only in the breeding season do males and females live together. 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; In Xishuangbanna, south of China, there is more food, so the moving distance is shorter.

The estrus mating period is generally from June 1 1 day to February of the following year. In estrus, the tiger's cry is particularly loud and can spread to 2 kilometers away. The gestation period is about 105 days, and each time, 1-5 cubs are born, usually 2 cubs. The newborn tiger cubs weigh about 1 kg, and they are breast-fed for 5-6 months. During this period, the tigress did not mate in estrus, so under natural conditions, the tigress can only reproduce once every 2-3 years. The female tiger is sexually mature at the age of 3, and the male tiger is later. The life span of a tiger is generally 20-25 years.

Due to the killing of human beings and the fragmentation of wild habitats, tigers have become rare and endangered species, listed as first-class protected animals in CITES Appendix of Washington Convention, and listed as endangered animals in IUCN Red List. According to the investigation in 20 16, the number of wild tigers in the world is 3890.
