摘      要：Background:Wetlands provide diverse ecological services to sustain rich biodiversity,but they are recklessly exploited around the *** Kolkata Wetlands(EKW;Ramsar site No.1208,~125 km^(2))was once very rich in faunal diversity that declined over the years due to various anthropogenic *** such scenarios,effective management plans need to contemplate local and landscape level initiatives and prioritize areas for *** the foraging guild structure and spatial patterns of relationship between bird and its environment provides important insight of ecological processes of ***,we carried out extensive surveys in 142 point count stations to explore the diversity and foraging guild structure of birds in *** addressed two important questions that how bird diversity varied from the outer periphery of the city towards the wetlands and how bird diversity is influenced by land cover features at local and landscape level in wetland *** goal of this study was to prepare a spatial map of avian diversity and to find the conservation priority areas for birds in this internationally recognized wetland ***:We recorded 94 species of birds and the Shannon diversity index values ranged between 1.249 and *** found that the avian diversity increased with increasing distance from city *** and insectivores were the dominant foraging guilds,followed by carnivores,granivores,frugivores and *** Linear Models revealed that bird communities were positively influenced by areas of wetlands,dikes and banks,agricultural field and emergent vegetation,and negatively influenced by built-up *** the projected spatial map of species diversity,74.15 km^(2)area has high ***,we identified 12.82 km^(2) of top 10%conservation priority ***:Low bird diversity near city periphery is related to habitat degradation due to anthropogenic *** of omnivores and insectivores
