Introduction to Bengal tigers: There are about 3-5 tigers in the reserve. The tigers live alone and occupy a certain area. Depending on the abundance of food, a female tiger occupies an area of 30 square kilometers, and the range of male tigers can be 4. The female tiger returns to her territory. Tigers mature at the age of 3 to 4 years and have one litter every 2 to 3 years. They give birth to 2 to 4 litters per litter, with a gestation period of 4 months. Tigers are the highest consumers in the entire ecosystem. A tiger has a lifespan of about 20 years and will eat about 30,000 to 50,000 kilograms of herbivores in its lifetime. A barking deer weighs about 25 kilograms. A tiger will eat 1,200 to 2,000 mammals weighing as much as a barking deer in its lifetime.
