Tigers utilize a variety of vocalizations to communicate over long distances. Roaring is produced in a variety of situations such as taking down large prey, signaling sexual receptivity and females calling to their young. These roars may be heard from distances over 3 km (1.8 mi.).

Moaning vocalizations are described as a subdued roar made while tigers are calmly walking with their heads in a downward position. This vocalization is audible for distances less than 400 m (440 yd.).

Chuffing are friendly vocalizations that generally consist of a soft brrr sound. These vocalizations are primarily used for greetings between tigers and only audible at close range.

Tigers use their tails to communicate with one another. A tiger is relaxed if their tail is loosely hanging. Aggression is displayed by rapidly moving the tail from side to side or by holding it low with occasional intense twitches.

Tigers may enhance their olfactory communication by using visual markings such as scrapes on the ground and trees.

Adult males and females both communicate to one another by marking their territories. An adult tiger will usually define the boundary of its territory by spraying urine because of the strong odor associated with it can last up to 40 days but they may also use feces for marking.
