Seasonal dynamics of avian diversity in mine spoil afforested areas: A study in and around NLCIL, Neyveli

Abstract

Bird biodiversity encompasses the variety and abundance of bird species within a given geographic area. The diversity of bird species is influenced by various factors including habitat availability, climate, geographic feature and human activities. Conservation efforts focusing on bird biodiversity are crucial for maintaining ecosystem balance, preserving biodiversity and ensuring the long-term survival of avian population. This study aimed to document the seasonal variation of avian diversity in and around NLCIL, Neyveli, during the period from October 2022 to June 2023. A total of 107 bird species were recorded belonging to 18 orders and 45 families. The highest number of avian populations were observed during the summer season, specifically from April to June. Additionally, the study identified three Near Threatened species and five migratory birds in the study area. These findings highlight the ecological significance of the mining area.
