This is a bird sanctuary located just 16 kms from Mysore. Birds of different flocks come here to breed annually from as far as Siberia. An amazing island upon the river Cauvery, it is a real treat to watch Crocodiles and birds from close quarters. The ideal time to visit this sanctuary is between July and October.

It is a very small sanctuary, being only 0.67 km². in area, and comprises six islets. Ranganthittu is located near the historic town of Srirangapatna.

History of the Park

The islets came into being when a dam across the Kaveri river was built in the 1700s. The ornithologist Dr. Salim Ali observed that the isles formed an important nesting ground for birds, and persuaded the Wodeyar Kings of Mysore to declare the area a wildlife sanctuary in 1940.

Natural History of the Park

Biomes
Most of the park falls under the Riparian biome, corresponding to the Indomalaya ecozone.

Flora
Riverine reed beds cover the banks of the islands, while the islands themselves are covered in broadleaf forests, with dominant species being Terminalia arjun (Arjun tree), bamboo groves, and Pandanus trees. Eucalyptus and Acacia trees have also been planted, which might lead to long-term eradication of native species. The endemic and threatened lily Iphigenia mysorensis of the family Colchicaceae grows in the sanctuary.

Fauna
The islands are host to numerous small mammals, including Bonnet Macaque, colonies of Flying Fox and common small mammals like Common Palm Civet and Indian Gray Mongoose and the monitor lizard.

The Mugger Crocodile or Marsh Crocodile is a common inhabitant of the riverine reed beds. Breeding water birds include Painted Stork, Asian Openbill Stork, Common Spoonbill, Woolly-necked Stork, Black-headed Ibis, White Ibis, Lesser Whistling Duck, Indian Shag, Stork-billed Kingfisher and other common birds like egrets, cormorants, Oriental Darter, and herons. The Great Stone Plover, and River Tern also nest here. The park is home to a large flock of Streak
