Abstract Vikramshila Gangetic Dolphin Sanctuary (VGDS) primarily established for the protection of endangered Gangetic dolphin, the national aquatic animal, also provides key habitat for different avian species, particularly migratory birds. This study examines the behavioural patterns including foraging, roosting and social interactions of migratory birds within the wetlands of VGDS. Field observations were conducted over multiple migratory seasons to document species diversity and habitat utilization. Several key species were identified that use the sanctuary as a wintering site, including the Bar-headed Goose (Anser indicus), Northern Pintail (Anas acuta), Black-tailed godwit (Limosa limosa) and Eurasian coot (Fulica atra). Behavioural analysis revealed that wetlands are crucial for foraging and roosting, with food availability and habitat health significantly affecting bird activity patterns. Wetlands are also important for resident and migratory birds’ interaction as many passerine birds' activity increases near wetlands during the migratory season. The presence of endangered and near-threatened species within wetlands emphasises the need for effective conservation measures to ensure the protection and sustainability of the sanctuary’s rich birdlife.
