The present study recorded 99 bird species which indicate the high diversity of avian fauna in the study
area. The study was carried out dividing the annual cycle into four seasons as pre-monsoon, monsoon,
retreating monsoon and winter. Analysis of Shannon –Weinner, Margalef’s and Simpson index showed
significant diversity of avian fauna. Comparison of Shannon –Weinner diversity index of the study
seasons showed that the winter season was more diverse than the other three seasons at 5% level (SI, H
= 4.072; MD, D =11.85; SIM, D = 0.9769). The maximum avian species were recorded during the
winter season and minimum during the monsoon. The study also recorded four vulnerable species. The
avian diversity of the study area is under great threat due to various anthropogenic and environmental
problems.
