Tigers are at the top of the food chain in all the environments they inhabit, making them the apex predator of their respective locality. Tigers are still entirely dependent on their ecosystem, however, and although they can eat anything, their physiology means they are most nourished by hooved animals such as water buffalo.
Although they have a preferred diet, tigers have been known to eat everything from crocodiles and birds to other large predators such as bears when short of food. Most tiger hunts are not successful. When they are, however, one large deer or wild pig can feed the animals for days or even weeks.
The tiger hunts using camouflage and surprise. As a result, stalking prey can take many hours, until the tiger pounces and attempts to isolate its prey if traveling in a herd, which is a common defense for most large herbivores.
Tigers are, in general, solitary animals, and are rarely seen with other tigers. Despite this, they cover a large amount of territory, often dependent on how much prey is available. Tigers will often gravitate towards fertile areas with plentiful water and vegetation, which are also the ideal conditions for their preferred prey.
