Berhampur: The mouth of the Rushikulya River in Ganjam district—best known as a mass nesting ground for endangered Olive Ridley turtles—has now emerged as a potential habitat for the critically endangered Irrawaddy dolphin.
Forest officials recorded a group of 13 Irrawaddy dolphins near Bateshwar under the Khallikote forest range during a three-day dolphin census conducted from January 20 to 22. According to media reports, the dolphins were seen surfacing and moving in coordinated groups, suggesting active use of the estuarine waters. The census findings indicate a healthy dolphin presence along the Purunabandh–Prayagi stretch, officials said.
The Irrawaddy dolphins, which are more commonly associated with Chilika Lake, may have expanded their range towards the Rushikulya river mouth. Previous surveys in the area have also documented other dolphin species, including bottlenose and humpback dolphins.
The estuary is internationally recognised as a major rookery for the Olive Ridley sea turtle, with thousands arriving annually for mass nesting, typically in February. It also serves as a seasonal habitat for several migratory birds, including the Bar-headed goose.
Wildlife experts say the sighting strengthens the ecological significance of the Rushikulya estuary as a biodiversity hotspot and underscores the need for enhanced conservation measures. Forest authorities have been conducting awareness campaigns among local fishing communities to promote the protection of marine species beyond turtles, encouraging broader stewardship of the coastal ecosystem.
