Do tigers hunt in packs?

The way of life of the tiger is built around hunting. And each tiger lives alone and they hunt alone. In the forests of Asia where nearly all tigers live (except the Siberian tiger in the Far East of Russia) the world's biggest and greatest hunter has no choice but to hunt alone because of the dense vegetation which is their habitat.

Hunting in a group would not be successful. Apparently, very rarely, they might hunt in a group under certain favourable circumstances but this is essentially a solitary hunter.

Their method of killing is to get near as possible to the prey animal using cover from their habitat and their camouflaged coat. They approach prey downwind from the prey animal. This means that their body odour is not carried towards the prey animal which might alert them.

The tiger has to get as close as possible to the targeted prey animal because they cannot sprint for great distances. They have to approach to about a hundred feet or less. 

Anything longer than that and they will fail. In fact, they fail often. Success comes in about one in 20 attempts. They will try several times a night to bring down an animal. Their prey animal is normally a deer of some species and they are quick. 

They need to kill large animals in order to survive successfully. They will normally succeed no more than once a week.
