The Hunting Observations of Bengal Tigers Laura Freeman Morgan Hulan Samantha Lambert HYPOTHESIS
Our hypothesis is that we believe the hunting behavior in Bengal tigers being in captivity rather than in the wilderness, has began to affect many natural instincts that Bengal tigers experience in the wild such as strategizing how they hunt and survive. April 25,2011

The Bengal tiger, or Panthera tigris, or sometimes know
as the Indian tiger. They live in mangrove forests of the sundarbans
in the eastern India and Bangladesh. BACKGROUND
There use to be 8 subspecies of tigers,
but because of poachng and forest destruction,
3 of the subspecies became extinct. BACKGROUND
The Bengal tigers do not like to share their hunting grounds, therefore the males need at least twenty square miles and the females need at least seventeen square miles of their home territory. MATERIALS & METHODS
The material we needed was pen, paper, and a video camera. PROCEDURES
First, we went to the Nashville zoo at Grassmere on Sunday at 3:00 p.m. and we watched the Bengal tigers eat what the zoologists gave them. PROCEDURES
Second, we recorded what we saw and how the Bengal tigers fed on their food. Third, when the Bengal tigers were done, we left to go home. PROCEDURES
Fourth, we watched educational videos on Bengal tigers on how they receive their food and how they eat it. Last we wold compare the notes we received when we went to the Nashville zoo at Grassmere and the notes we took while watching the Bengal tigers videos. RESULTS
However with the little data we did obtain we were able to realize that Bengal Tigers in captivity only sometimes get fed live small mammals such as rabbits. Background
Throughout their home range they have many dens, in which they use the one that is more convenient to their needs. Bengal tigers are nocturnal carnivores that hunt their prey at night, which means they have excellent eyesight, hearing, and also a good sense of smell. Background
They are powerful and also quick for short distance, but for long distance they stalk their prey until they are close enough to attack. To help the Bengal tiger to camouflage into the wilderness to hunt for it’s prey, the Bengal tiger are born with black and brown stripes. Background
When the Bengal tiger is attacking a smaller prey it bites the back of the neck , but on a larger prey it bites it’s throat. It mainly kills gaur (wild ox), buffalo, wild boar, monkeys, chital(axis deer) and etc. The tiger could kill a prey that is twice its size, but prefers to attack young or old animals because the prey has less resistance. Background
After killing its prey, the tiger drags the carcass to thick cover to feed but the tiger could also go to the water to eat so if the tiger gets thirsty it doesn't have to leave the prey to far from where it is or to leave the possibility open for hyenas or lions to take its meal. When it has eaten enough, the tiger hides the carcass under leaves and grass, and will return to it later. RESULTS
Although mostly the tigers are fed meat already prepared for them to eat and not live but just ground up chunks of meat. We also came to find many Bengal Tigers do not necessarily lose their hunting instincts but they seem to just become dull from the lack of not having to use them and not catching their own prey. Most Bengal Tigers also are more active in the wild not only from hunting but also from interaction with others of its species. In captivity they get bored and often have toys to play with to keep them busy but often become less active. CONCLUSION
With looking at this research we support that bengal tigers predatorial and hunting instincts are in fact affected from staying in captivity. Since bengal tigers are not required to hunt and use their natural instincts in captivity, they seem to become dull over time.
