Chitwan has deer, pigs, gaur, leopards, tigers, wild dogs, monkeys, and reptiles including the rare gharial. Of its over 500 species of birds, the most conspicuous is the peacock. But you go to Chitwan chiefly to see the one-horned rhino. I never fail to wonder at the placid tolerance of rhinos for humans, at least those on elephant-back. In the open grassy swamp at Kaziranga, you can see rhinos grazing miles away. In Chitwan, they suddenly shuffle out of the undergrowth, or wallow nonchalantly in a pool like gauche models posing for photographs. Except for some warning snorts from a mother with a calf, we faced nothing remotely menacing. Had we been on foot, it might have been a different story, though the authorities feel confident enough to mark a &lsquobirdwatcher&rsquos trail&rsquo.
