A field study was conducted on the avifaunal diversity of Ankasamudra Lake. Ankasamudra is a small village located in Hagaribommanahalli Taluk, Ballari district, Karnataka-India, between 15° 7’ 50.44" N and 76° 13’ 52.83" E. This lake is located at the outskirts of the village Ankasamudra near the backwaters of Tungabhadra Dam (T.B Dam) spreaded in 244 ha area. It is being filled with both either natural rainwater or by lifting backwater of T.B Dam. Since it is filled with water throughout the year and Acacia trees grown in the lake provided space for nesting, roosting and breeding for bird species during winter season, which include several local and migratory bird species (approximately 166 species) such as waders and other birds. Highest population of Rosy Starlings and Barn Swallows are noticed in addition to Comb duck, Black tailed Godwit, Long tailed stints, Northern Shovelers, Pintail ducks, Painted storks, Open billed ducks, Spoon-billed ducks, Cormorants, Egrets, Moor hens, Black winged stilts, Glossy ibis, Black-headed ibis, Purple heron, Grey heron, Common teals, Whistling ducks, Spot billed ducks, Garganey, Pelicans, White ibis, Oriental darters, Blue tailed green bee eater, Sand pipers, Red shank, Painted snipes, raptors like Brahminy kite, Marsh harriers and other prominent residents were also recorded.
