On the banks of river Cauvery lies a gem of a bird sanctuary. Though less than a square kilometer in area, Ranganathittu has a very high bird count, both in species and in numbers. In spring and summer, aquatic birds like spoonbills, river terns, open bill storks, pelicans, painted storks nest in small islands in the river, while terrestrial birds like Tickell's blue fly catcher, fan-tail flycatchers, peafowls, tailor birds flitter about on the river bank.
