Avifauna

The wintering migrant birds which flock to the sanctuary were recorded at different periods during the winter months. The early arrivals in October were gadwall, northern pintail, northern shoveller, common teal, common pochard, and common coot. The birds recorded during November were mallard, Indian spot-billed duck, and knob-billed duck. The departure of the birds from the sanctuary was also noted in different months, towards the end of the winter season. The summer birds recorded were the lesser whistling duck and the cotton teal.

Threats

Major threats identified to the sanctuary are anthropogenic pressure involving encroachment of land, collection of firewood, grazing of cattle, and clearing of new vegetation on the borders of the wetland. During severe summer months, water reserves in the lake are inadequate to maintain the biodiversity of the environment. Improper management is also said to be causing problems.

Conservation

The sanctuary, as a wetland which is encircled by agricultural lands, provides adequate feeding grounds and safety for the birds that visit. The farmlands with scattered trees provide foraging areas and the lake provides a food supply to the birds in the form of crustaceans and invertebrates, as well as the water plants and plankton that flourish in the lake.
Due to the threats faced by the sanctuary, the conservation measures which need to be addressed are: establishing patrols to minimize disturbance when the birds visit to breed; and enhancing the water supply to the lake, which is purely rain-fed, from any nearby canal system.
