Tiger hunting is the capture and killing of tigers. Humans are the tigers' most significant predator, and illegal poaching is a major threat to the tigers. The Bengal tiger is the most common subspecies of tiger, constituting approximately 80% of the entire tiger population, and is found in Bangladesh, Bhutan, Myanmar, Nepal, and India and has been hunted in those countries for centuries. The tiger has historically been a popular big game animal and has been hunted for prestige as well as for taking trophies. Extensive poaching has continued even after such hunting became illegal and legal protection was provided to the tiger. Now a conservation-reliant endangered species, the majority of the world's tigers live in captivity. Tigers were once considered to be harder to hunt than lions, due to their habit of living alone in dense cover and not noisily asserting their presence with roars as often.
