The present study was carried out from July 2015 to June 2016 to assess the diversity, distribution and species composition of birds inhabiting riverine ecosystem. The study was done along the River Ganges, which is the largest river of Uttar Pradesh, flowing through district Raebareli. The presence of birds in the study area was recorded in early morning by a point count method using binoculars and SLR cameras. A total of 38 species of birds were recorded belonging to 10 orders and 19 families. The order Charadriiformes was dominated by 10 species. It accounts for 26.31% of the total birds followed by Palecaniformes which was dominated by 09 species and account for 23.68%. According to extant IUCN Status, most of the species were placed in Least concerned (32), 3 in Near Threatened, and 3 in Vulnerable category.A total of60.5 % were observed to be resident, 34.21% resident migrants and 5.26% were migrants. Maximum species diversity was recorded at Gegaso (1-D= 0.9515 & H’=3.304) and minimum at Dalmau (1-D= 0.9441 & H’= 3.192).Although the study area is resourceful in terms of habitat and food availability yet during the study it was found that various anthropogenic and environmental factors are exerting negative impact on population of birds.
