The present study was undertaken from November 2020 to October 2021 to understand the bird species diversity, and variation in their seasonality, near the National Thermal Power Corporation (NTPC) area of Talcher located in Angul district of Odisha state in India. The identified birds included 668 individuals of 90 species (including three near-threatened species) belonging to 18 orders, 41 families and 75 genera. As per the study, Passeriformes is found to be most dominant with 34 species (38% of total bird species). Considering the feeding guilds of birds, insectivore bird species were found in higher number (32 species) followed by carnivores (16 species), and then omnivores and frugivores (10 species each). It was found that the winter season was the most species rich (70 species, 328 individuals), and the monsoon season the least (43 species, 127 individuals). The Shannon-Wiener index (H' = 3.48) was also found to be high in winter season but the evenness index (E = 0.65) was found to be higher in monsoon season. The cluster analysis showed that the bird composition of the summer season strongly correlates with bird composition of the winter and monsoon seasons, but the bird composition of the monsoon season is not significantly correlated with bird composition of the winter season. The results from the study can act as the baseline for further research on birds in the Angul district of Odisha.
