Nagi Bird Sanctuary

Nagi Bird Sanctuary is a reservoir-based bird sanctuary centered on the Nagi Dam on the Nagi River near Jhajha in Jamui district, Bihar. Notified as a bird sanctuary and designated as a Ramsar Site in 2024, it covers about 7.91 sq km including the reservoir and surrounding area. It is notable for large winter congregations of migratory waterbirds, including bar-headed geese, and forms a paired wetland system with nearby Nakti Bird Sanctuary.

Visitors can expect a large reservoir and wetland landscape surrounded by dry deciduous forest and rocky terrain. The sanctuary offers open water, mudflats and shallow edges where migratory and resident waterbirds congregate in winter. Visitors can explore embankment areas, watchtowers and viewing points for birdwatching and photography. The setting is quiet and natural with limited built infrastructure, focused on nature observation and sightseeing.

Nagi Dam was constructed on the Nagi River to create a reservoir for irrigation and water storage. The reservoir and its surroundings were notified as Nagi Dam Bird Sanctuary to protect habitat for migratory waterfowl. The sanctuary was designated as a Ramsar Site in 2024, recognizing its international importance as a wetland, along with the nearby Nakti Bird Sanctuary.
