Instructions
Watch two tigers as they approach one another and listen for "chuffing," which is a tiger's way of giving a friendly greeting. Identify chuffing by listening for four consecutive "brrr" sounds coming from each tiger.
Look at the tiger's tail to identify its feelings toward an approaching animal. A hanging tail is an indication that it's feeling contented. A tail that's waving from side to side shows that the tiger is feeling threatened or territorial.
Identify the meaning of a tiger's roar, which can be heard over a distance of three kilometers. A snarling roar accompanied by bared fangs is a warning call; it means that the tiger is feeling territorial and is telling other tigers in the area to keep away. A roar that is made without baring the teeth is a mating call to invite tigers of the opposite sex closer. A roar that sounds "soft" is used by a mother tiger calling its cubs.
Look at the tiger's ears. Forward-facing ears mean that the tiger is alert and curious, whereas flattened ears mean that the tiger is feeling defensive.
