Pacific Golden Plovers, Curlew Sandpipers, Common sandpipers, Wood Sandpipers, Little Ringed Plovers, Pheasant-tailed Jacana are some of the other species of birds you'll be able to spot while visiting Bundala. Kokara, a water tank which is situated close to the Bundala lagoon is a great place to observe elephants in their natural habitat at the break of down. Visitors are however advised to proceed with caution when observing elephants as they can get quite aggressive if they are startled due to elephant-human conflicts that have occurred in the area. The area is also a great place to witness a wide variety of butterflies, mammals and reptiles.
