Suhayn Wetland Bird Sanctuary

Overview: The Gangetic Interfluvial Wetland

Occupying a vast natural geological depression spanning over 1,200 hectares across the historic Shahabad plains of Bhojpur and eastern Buxar districts in western Bihar, Suhayn Wetland is one of the Central Gangetic Valley's most critical seasonal waterbird refuges.

Situated within the fertile **Ganga-Sone Doab** (the interfluvial plain between the sacred Ganga to the north and the wide sand-laden Sone River to the east), Suhayn functions as a gigantic natural reservoir. During the southwest monsoon, surging floodwaters inundate the depression, depositing nutrient-rich silt and replenishing a network of interconnected marshy channels, seasonal lagoons, and agrarian *diaras*.

As water levels gradually recede from October to March, the wetland transforms into a haven for thousands of wintering waterfowl navigating the **Central Asian Flyway**. Foremost among them is the golden-orange **Ruddy Shelduck** (Tadorna ferruginea, celebrated in Indian poetry as the *Chakrawak* or *Surkhab*), which forms massive daytime congregations along the muddy shoreline.

Hydrology & Doab Zonal Stratification

The seasonal water cycle of the Ganga-Sone floodplain dictates the ecological zones of Suhayn:

The high concentration of freshwater molluscs (particularly *Pila globosa* and *Bellamya bengalensis*) provides an inexhaustible food supply for wading storks and shell-cracking waterfowl. The underlying Sone river sand aquifers maintain gentle subterranean seepage that prevents the core depression pools from desiccating during the blistering summer heat.

Avian Diversity & Flagship Species

Suhayn serves as a pivotal refueling and wintering hub for high-latitude migrants:

Raptors patrolling the open floodplain skies include the **Western Marsh Harrier**, **Black-winged Kite**, and **Peregrine Falcon**, which prey on weak or injured waterfowl.

Diara Silt Farming & The Folklore of the Chakrawak

In classical Sanskrit literature and Bhojpuri folklore, the Ruddy Shelduck (*Chakrawak*) is celebrated in the verses of Kalidasa as the timeless archetype of romantic devotion. Rural legend holds that mated pairs are condemned to call out across the opposite riverbanks during darkness, reuniting joyously only at dawn.

The local agrarian communities of Bhojpur and Buxar practice traditional recession farming (*Diara Kheti*) on the exposed silt margins. Farmers cultivate pulses, mustard, and melons without excessive synthetic chemicals, maintaining a symbiotic relationship with wintering birds. The birds provide natural pest control by consuming weed seeds and insect larvae, while their droppings naturally fertilize the fertile alluvial soil.

Annual waterbird surveys conducted by postgraduate botany and zoology researchers from Maharaja College, Ara, in collaboration with the Bihar State Wetlands Authority, have recorded an encouraging stability in species diversity. Rural youth groups across Shahabad have initiated voluntary birding clubs that monitor waterfowl numbers, educate local school children on flyway conservation, and safeguard the riparian fringe against commercial encroachment.
