Seasonal aggregate effects of water bird populations on tropical rural lake

The present study indented to find the cumulative summer effects on the water bird communities of Vellode Lake. Ornithological studies tinted the presence of 38 species of water birds. Exclusively presence of vulnerable Pelecanus crispus, near threatened Mycteria leucocephala Threskironis melanocephalus and Anhinga melanogaster , were noteworthy recordings of the bird survey. Limnological studies uttered that the fluctuations of water level and nutrient release alters the chemical quality of the lake water especially dissolved oxygen, pH and total nitrogen and sequential modifications among biological oxygen demand and chlorophyll-a. Present study enlighten the superfluous difficulties of the lake ecosystem and refurbishing strategies. Expounded observations and suggestions of the study should help the lake managers and policy makers to retain the naturalistic features of the lake.
