Abstract
Birds are recognized as sensitive indicators of the health and functionality of ecosystems in freshwater wetlands. Consequently, the assessment of bird populations in wetland habitats is emphasized from a sustainable management perspective. Bird surveys were conducted from October 2023 to October 2024. The purpose of these surveys was to evaluate the community composition and status of birdlife in the Sasthamnada wetlands, which is a significant bird area located in Thiruvananthapuram, Kerala. Data were collected using point counts and opportunistic methods. A total of 41 bird species from 18 families and 16 orders were documented. Among the avifauna documented, one species is listed as Near Threatened on the IUCN Red List of Threatened Species. These wetlands also support five species of birds that have a declining population trend globally; this research outlines the populations and threats affecting Black-headed Ibis species. Seasonal variations in the populations of these birds were not observed. Major threats identified included the disposal of solid waste, the proliferation of weeds, grazing by animals (such as cattle and goats), and the presence of stray dogs. This study offers foundational data for future research on the monitoring of bird communities and effective management of the Sasthamnada wetlands in Kerala.
