Abstract	Wind-based power production is an excellent substitute for energy generation. Internationally, India stood at fourth place in wind power production with an installed capacity of 51. 3 GW by June 2025. In view of possible bird and wind turbine interactions like direct contact with revolving blades, towers, nacelles, and associated power lines and meteorological masts, the Forest Advisory Committee of the Ministry of Environment, Forests & Climate Change, Government of India, recommended a bird study as part of listing out the raptor diversity in the areas of their proposed Wind power projects. The current avian study report was conducted as per the strategies issued by GOI, MoEF & CC, New Delhi, vide F. No. 8 47/2008-FC dt 16th March 2008, which was conducted in Ramagiri East and West reserve forests, situated in combined Ananthapuramu district of Andhra Pradesh, study was conducted to assess raptor diversity in post wind turbine establishments which were previously assessed and listed avian diversity in the study area, now in focus of post turbine establishments in the year 2017 currently its impact were evaluated between August 2023 to March 2025, study area spread approximately over 55. 73 hectares of mosaic microhabitats categorized into Acacia Forest (AF), Euphorbia-Salvadora Forest (ES), Mixed thorn forest (MTF) and Prosopis forest (PF). The survey carried out in the study area identified the presence of 119 avian species belonging to 51 families. Among identified 119 species of birds, 98 species are resident, 19 are winter migrants and 2 species are summer migrants, without any change in comparison with the previous studies. A comparative study of these populations of each species across different habitats was also carried out, of which mixed thorn habitat recorded the highest species count of 45, followed by 28 species in Acacia habitat, 26 species in Euphorbia Salvadora habitat and 20 species in Prosopis dominant habitat. Accipitridae in the order Accipitriformes are the most dominant family, consisting of 16 species with strong curved bills, and exhibit various morphological forms as per the habitat and diet. The methodology we used to estimate raptor species and species composition includes the line transect method and a standardized visual search method.
