Abstract: Wetlands provide a vast variety of faunal diversity among which avian diversity is much important as wetlands offer them a variety of habitats and they occupy these habitats according to their niches. We conducted a study during the winter season in Mangalajodi wetland, which is located in the northern part of Chilika Lake, an important Ramsar site of Orissa, India. During this study, the diversity of the waterbird community was observed in Mangalajodi Wetland and in total, 50 species of water birds belonging to 37 genera and 17 families were recorded. Among them, the families Anatidae and Ardeidae both have recorded the highest observed number of species; as well as the highest percentage of occurrence (16%) in the avian community. The family Scolopacidae has recorded the second highest observed rate of relative abundance (14%); mostly due to the huge abundance of its sole member, the Black-tailed Godwit (Limosa limosa). The community consists of 52% Resident; 42% Resident-migrant and 6% Migrant water bird species. In the feeding guild analysis, the Insect and other terrestrial invertebrate feeder (I) and the Aquatic invertebrate feeder (IN) guilds have the most number of recorded avian species. The feeding guild affiliations also point out that the overall community of the wetland site is fairly rich in its composition as it houses bird species belonging to various feeding guilds.
