A survey of birds was carried out from March 2007 to August 2007. The birds were observed during most active period of the day i.e. 0515 to 0830 hrs and 1530 to 1830 hrs. A total of 200 bird species were recorded in the sanctuary.

Out of the 9 species of vultures, more than 90 per cent of two species of vultures, the white-rumped and long-billed, have been wiped out. The main reason for such a decline in the population has been attributed to presence of diclofenac. The manufacture of diclofenac for cattle is now banned.
