Sundarbans -
The biggest colony of the `Royal Bengal Tigers' - the Sundarbans. These evergreen mangrove forests pulsate with a myriad forms of life. Above the Kingfisher and White-bellied Sea eagle add a brilliant burst of colour. The sea creeps in at high tide. The ebbing waters reveal nature so alive on the glistening mud flats. The land is split by numerous rivers and water channels all emptying into the Bay of Bengal. It is believed that Bonbibi, the goddess of the forest, protects the wood-cutters, honey-collectors and fishermen on their hazardous missions. For, as the saying
goes, `Here the Tiger is always watching you'. Some people, believe that they could," however, have got their name from the profusion of Sundari trees. Some wild creatures are spotted deer, boar, monkey, crocodile, python, Salvatore lizards, and a wide range of water birds.
