Field Observations on Avian Diversity in a 15 km Radius of Gangaikondan, Tirunelveli, Tamil Nadu

Gangaikondan is a rapid industrial development in recent decades. This study was carried out in five different habitats such as wetland, agriculture, forest, residential areas, and urban greenbelt. During the study period a total of 111 bird species were recorded, Wetland habitat (Aquatic and pond edge vegetation) compressed of the highest number of species (92 species), followed by agricultural habitat (76 species), forest habitat (62 species), residential habitat (23 species), and urban greenbelt habitat (15). Spotted Dove and Red‑vented Bulbul were the common birds species present across five habitats, while habitat-specific dominance shows Eurasian Coot in wetland, Asian Green Bee‑eater in forest and agriculture, House Sparrow in residential areas, and Common Myna in urban greenbelts. These findings provide essential baseline information for Environmental Impact Assessments and emphasize the importance of conservation-focused land-use planning in this rapidly industrializing landscape.
