Assessment of Avian Diversity in Miyawaki Micro-Forest Plantations of Yadadri Bhuvanagiri District, Telangana, India

Abstract

Aims: To assess bird diversity in the Yadadri Forest Model, Yadadri Bhuvanagiri District, Telangana. Three plantations established in 2018, 2019, and 2022 were evaluated at a spacing of 1 m × 1 m. Place and Duration of Study: Yadadri Bhuvanagiri District, Telangana, during 2022–2023. Methodology: During the study period from January 2022 to June 2023, bird visits to the micro-forest plantations established at 1 m × 1 m spacing were documented monthly through visual observations. The resulting data were used to calculate relative abundance, species richness, species diversity, and species evenness. Results: The relative abundance of the Common crow varied across the three plantations, with 6.86% in Plantation 1, 10.76% in Plantation 2, and 11.70% in Plantation 3. House sparrow had relatively high abundance in Plantations 1 and 2, at 9.42% and 7.89%, respectively. Rufous treepie showed the lowest occurrence across the plantations, with values of 0.00% in Plantations 1 and 2 and 0.45% in Plantation 3. Plantation 2 had the highest species evenness (0.98), whereas Plantation 1 had the highest species diversity (3.06), indicating variation in bird composition and community structure among plantations. Conclusions: Bird diversity and composition, including habitat, IUCN status, and feeding habits, were recorded at the same micro-forest spacing. The bird community included 10 omnivores, 10 insectivores, 4 granivores, 3 carnivores, 3 frugivores, and 1 herbivore.
