Description :
In the northern hemisphere, the deep chill of winter closes the lakes and streams and snow fall covers the land as well
as the total vegetation, compelling the birds to move towards warmer region around equator. The Indian subcontinent
offers the sufficient food and water as well as the comfortable temperature to these migratory birds. The Rajasthan
harbours the maximum variety and number of migratory birds, because of abundance of aquatic vegetation, fish,
frogs, water insects, molluscs and planktons in the wide spread lakes, provide ideal conditions for the birds to stay.
The migratory birds have been observed to reach up till the Chennai and Tamilnadu in the South India. The four
water bodies of the sanctuary as well as the perennial water holes around Gajner, the Darbari water pond and the
Kodemdesar water pond are the main water bodies to harbour the thousand of migratory birds reaching here since
immemorable time. The water bodies of Gajner Sanctuary (Bikaner, Rajasthan) harbours approximately 6 to 7
thousand birds belonging to 17 species staying from Nov. to April every year (Chouhan 1994).The large number of
birds coming regularly and staying comfortably in Chunda sagar, Gajner Sanctuary (Bikaner, Rajasthan)for food and
