Abstract— Wetlands serve as critical stopover habitats for migratory birds, offering food, shelter, and breeding grounds. The T.S. Chanakya Wetlands in Navi Mumbai, however, face increasing threats from urbanization, industrial discharge, and pollution. This research evaluates how water quality affects bird diversity and behavior through the examination of samples collected from three different locations —urban coastal, foraging and feeding, and creek-mangrove zones. Factors including cadmium, chromium, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and nitrates. nitrites, and pH were examined. Results revealed that cadmium and chromium exceeded permissible limits in mangrove and urban sites, while BOD and COD levels indicated heavy organic contamination. Such conditions reduce oxygen availability, alter aquatic food webs, and degrade foraging habitats. Field surveys recorded diverse species including flamingos, curlews, sandpipers, and gulls, with observable shifts in feeding and roosting behavior linked to pollution levels. The findings emphasize the urgent need for stricter pollution control, mangrove restoration, and sustainable urban planning to conserve wetland ecosystems and ensure the survival of migratory birds in urban landscapes.
