When not subject to human disturbance, tigers are mostly active during the day. Like other feline species, tigers are capable of climbing trees, but they are not so adept at doing this, so they rarely climb; however, exceptional cases have been recorded such as a tiger attempting to climb a tree to hunt monkeys . They are a good swimmer and often bathe in ponds, lakes and rivers to stay cool in the daytime heat. The individuals can cross rivers up to 7 km (4.3 mi) wide and can swim up to 29 km (18 mi) in a day. During the 1980s, a tiger was observed regularly hunting prey through a deep lake in Ranthambhore National Park.
The tiger is a highly active territorial animal, and individuals spread over distances of up to 650 km (400 miles) to reach tiger populations in other regions. The tigers observed in Chitwan National Park begin to disperse from their natural areas as early as 19 months. Four females scattered between 0 and 43.2 km (0.0 to 26.8 mi) and 10 males ranged between 9.5 and 65.7 km (5.9 to 40.8 mi). None of them cross over extended cultivated areas of more than 10 km (6.2 mi), but migrate through forested habitats.
