Tigers, like this female in India's Bandhavgarh National Park, spend hot days in a languorous laze, storing energy for nights of hunting. Over the last hundred years, hunting and forest destruction have reduced tiger populations from hundreds of thousands of animals to perhaps fewer than 2,500. Today Bandhavgarh claims to maintain the highest density of tigers in the country.
