Udhwa Lake Bird Sanctuary – Jharkhand’s Hidden Paradise for Migratory Birds

Udhwa Lake Bird Sanctuary, located in the Sahibganj district of Jharkhand, is the state's only bird sanctuary and a true paradise for bird watchers and nature enthusiasts. Spanning across 5.65 square kilometers, this wetland ecosystem is formed by two picturesque backwater lakes of the Ganges River — Patauda Lake and Berhale Lake.

Recognized for its ecological importance, the sanctuary was declared a Ramsar Site on February 1, 2025, highlighting its role as a vital habitat for numerous migratory and resident bird species.

Ecological Significance

Udhwa Lake Bird Sanctuary is a naturally formed Ganga backwater wetland, shaped through the oxbow lake concept. It plays an essential role in water regulation, storing excess water during floods and releasing it back into the river. The sanctuary's unique hydrological connection with the Ganga supports a diverse aquatic and terrestrial ecosystem.

The National Mission for Clean Ganga (NMCG) has taken a special interest in conserving and managing this wetland due to its high ecological value and contribution to biodiversity conservation.
