Selected Birds Population at Pulicat Bird Sanctuary: A Statistical Review

Kanchi Siva Prasad

Abstract: Pulicat Bird Sanctuary, one of the most significant coastal wetland ecosystems in South India, supports a rich diversity of resident and migratory avifauna. The present study provides a statistical review of the population dynamics of selected bird species at Pulicat Bird Sanctuary, with an emphasis on seasonal variation, species composition and abundance patterns. Systematic field surveys were conducted across representative habitats of the sanctuary during different seasons and bird populations were recorded using standard census techniques. Quantitative data were analyzed using descriptive statistical tools to assess population trends, relative dominance and frequency of occurrence of selected species. The results indicate clear seasonal fluctuations in bird populations, with a marked increase in migratory species during the winter months November to February, particularly among Greater Flamingo, Grey Pelicans, Grey Herons and Night Herons. Resident species exhibited relatively stable population levels throughout the year, reflecting habitat adaptability and resource availability. Statistical analysis revealed significant variations in species abundance across seasons, highlighting the influence of environmental factors such as water levels, food availability and climatic conditions. The study underscores the importance of long-term statistical monitoring to understand avian population dynamics and to evaluate the ecological health of wetland ecosystems. The findings from the years 2019-20 to 2023-24 provide baseline data that can support conservation planning, habitat management and sustainable biodiversity preservation efforts at Pulicat Bird Sanctuary.
