The Ranganthittu bird sanctuary is a cluster of islands and one large island in a crocodile infested part of the Kaveri river. It is because of the lurking danger of the crocodiles that the birds thrive, as they are the guardians of the island which is so precious for the birds to nest on. The treat of the crocodiles is far less than the threat of the other predators that the crocodiles scare off (eat). Symbioses.
It is a frequent stop of for us between Bangalore and the southern tiger reserves of Nagarhole (Kabini) and Bandipur! A greta birding spot indeed! :)
