Birds are the key agents for various ecosystem services. Degradation and encroachment of bird’s habitat affects their population and diversity. The conservation outside the protected areas have been completely neglected and hence, this leads to the study involving avi-faunal diversity in several places of Ramdurga Taluk based on the availability of natural vegetation, wetlands and agricultural lands by opportunistic counts and line transect method. The study recorded 51 species of birds, belonging to 11 Orders and 31 families, of which 28 bird species belongs to the Order Passeriformes and are common to the region. Chaetornis striata (Bristled grass-warbler) and Ciconia episcopus (White necked stork) are the two vulnerable species identified in the study area. Buteo rufinus (Long legged buzzard), Circus melanoleucos (Pied harrier) and Pavo cristatus (Indian peafowl) belongs to Schedule I of Wildlife (Protection) Act, 1972. Maximum number of birds were recorded in Hirekoppa tank followed by Korekoppa and Itnal. Diversity of avifaunal species recorded in Ramdurga Taluk (51 species) is higher when compared to the bird diversity recorded by the Karnataka Forest Department within Ghataprabha Bird Sanctuary (30 species). Study shows that avifaunal species are largely attracted towards water bodies followed by wetland agro-ecosystems due to the availability of food, water resources, habitat and breeding sites. Degradation of wetland agro-ecosystems and forest lands have to be minimized and natural vegetation patches have to be conserved in order to protect the avifaunal diversity and maintain their population trend. Therefore, steps taken towards the conservation of wetlands, wetland flora and natural vegetation indirectly leads to the conservation of avifaunal population
