The physico chemical and microbial analysis of the lake water of Vaduvur bird sanctuary was carried out during the period of pre monsoon, monsoon and post monsoon periods. The study revealed that the levels were found to be higher during the pre-monsoon and post monsoon period. but the statistical analysis revealed that it was found to be insignificant (p<0.05). The microbial analysis revealed that during monsoon period it was found to be higher bacterial count, among the bacteria observed the vibrio counts were found to be less but other heterotrophic bacteria were found to be higher. Avifaunal diversity status and abundance of Vaduvur bird sanctuary is composed of small man-made reservoirs interconnected by an ancient network of canals and fed by the Vennaru reservoir, in the semi-arid district of Thiruvarur. The Vaduvur Lake in Tamil Nadu, India, is one such wetland that is home to a diverse range of migratory and resident birds. Despite the fact that this lake has just been designated as an Important Bird Area (IBA) by the Indian Bird Conservation Network, no attempt has been made to research it or the avifaunal species that rely on it. Thus, the water of reservoir is favorable for faunal diversity, rich in dissolved oxygen and supports variety of aquatic weeds and fishes, it has been found to be suitable habitat for bird fauna. Acacia nilotica (planted), Prosopis chilensis, Azadirachta indica, and Tamarindus indica comprised the vegetation in and around the lake. The prime breeding habitat was produced naturally.
