Established in 1940 by renowned ornithologist Dr. Salim Ali, Ranganathittu Bird Sanctuary is a must for all nature and bird lovers. The very sky in Ranganathittu turns into an air carpet for the birds, from around the world, to roost and breed. Situated 13 kms from Mysore, the Sanctuary is set around a handful of tiny lush green islands on the river Cauvery. It is an ideal spot for picnicking and bird watching. During the migrating season (June - November) the river Cauvery feeds the lake in the Sanctuary abundantly, and the rivulets attract migrating birds in large numbers.

Ranganathittu is the home for an astonishing variety of exotic birds from as far away as Siberia, Australia, North America, Middle East, Egypt, China, Africa, Europe and many other places. These birds migrate from their home for their annual Indian breeding holiday. Cranes, herons, pelicans, darters, spoon bills, kingfishers, open bill stork, white ibis, little egret, darter, pond cattle-egret, cormorant, varieties of wild ducks, peafowl and partridges are some of the notable natural ambassadors. These exotic birds migrate from distant places, roost and breed here with the local fauna during the winter months and fly back with their young ones, every year. Wild fowls and other forest birds are found in plenty among existing wildlife.

Ranganathittu is a tranquil spot away from the city. Situated on an island formed as a result the Cauvery River splitting into two, it treats you to some glorious sights and surprises. A basket of visual delights - crocodiles basking under the sun, otters running free and flocks of birds gathered on tiny islands. The wind whistles while passing the bamboo growth, producing natural music. Even the thick jade coloured moss in the rivulets' banks is a sight to behold. The view from the bird-watch house gives a momentary feeling of satisfaction of being one with nature.
