This investigates the diversity if aquatic avifauna in Komati Cheruvu, Siddipet, and its potential impacts on invertebrate’s fish population, focusing on the interplay between water quality, avifaunal activity, and ecosystem health. From February 2024 to August 2024, a total of 12 birds’ species were identified, representing a range of ecological niches and feeding habits. These species include Ardea alba, (Great Egret), Cygnus atratus (Black Swan), Threskiornis melanocephalus (Black-headed ibis), and members of the Alcedinidae family (Kingfisher), among others. Each species role in the aquatic food web was analyzed, particularly their feeding patterns, which influence the abundance and diversity of invertebrate populations.

The study highlights how piscivorous species, such as the kingfisher and cormorant, exert direct pressure on fish populations, while other species, like the black headed ibis and painted stork, contribute to ecological balance by feeding on invertebrates thus indirectly supporting fish populations. Observations suggest that variations in bird activity, particularly in foraging behavior, are linked to seasonal changes, water level fluctuations, and habitat quality. The Prescence of invasive bird species, such as the black swan, poses questions about their Ling term ecological impact on native species and water quality.

Water damage from avian activities was noted in areas of high bird concentration, where sediment disruption and nutrient input were higher, potentially leading to eutrophication and degraded water quality. This is turn affects invertebrate communities, which are crucial for fish diets, leading to cascading effects on fish diversity and abundance.
