Tigers are thought to be nocturnal

Tigers are thought to be nocturnal predators, hunting at night. However, in areas where humans are typically absent, they have been observed via remote-controlled, hidden cameras, hunting during the daylight hours.
They generally hunt alone and ambush their prey as most other cats do, overpowering them from any angle, using their body size and strength to knock the prey off balance. Successful hunts usually require the tiger to almost simultaneously leap onto its quarry, knock it over, and grab the throat or nape with its teeth.
Even with their great masses, tigers can reach speeds of about 49–65 km/h (30–40 mph), although they can only do so in short bursts, since they have relatively little stamina; consequently, tigers must be relatively close to their prey before they break their cover.
If the prey catches wind of the tiger's presence before the moments of the pounce, the tiger will usually abandon the hunt rather than chase prey or battle it head-on. Tigers have great leaping ability; horizontal leaps of up to 10 m (33 ft) have been reported, although leaps of around half this amount are more typical.
However, only one in 20 hunts, including any instances of stalking in proximity to potential prey, ends in a successful kill.
An adult tiger can go up to two weeks without eating, but then can gorge on up to 34 kg (75 lb) of flesh at one time. In captivity, adult tigers are fed 3 to 6 kg (6.6 to 13 lb) of meat a day.
