Ranganathittu Bird Sanctuary is a bird sanctuary in the Mandya district of Karnataka, India. It covers an area of 67 sq km (square kilometer) and consists of six islets on the banks of the river Kaveri. The historic town of Srirangapatna is nearby.
In 1940, the famous ornithologist Dr.Salim Ali observed that the islets formed an important nesting ground for birds. He persuaded the Wodeyar Kings of Mysore to declare the area a wildlife sanctuary. The best time to visit is during the water birds' nesting season, which is from June to November. The best time to observe migratory birds is in December.
