The sprawling lake at Vaduvur with the Kothandaramaswamy Temple in its backdrop is full of birds giving a pleasant sight to passers-by and tourists.
Other winged visitors in both the sanctuaries are little, cat and large egrets, Ibis, Painted Stork, Grey Pelican, Pintail Duck, Teals and Herons.
The Vaduvur lake, which houses a sanctuary, is 25 km from Thanjavur and attracts more than 30 species of water fowl. A favourite spot for migratory birds, more than 20,000 birds visit this area every year in the months of November and December.
