Preliminary checklist of avifauna from All India Institute of Medical Sciences, Guwahati, Assam, India

Bird diversity in various types of habitats, including institutional campuses, underlines the importance of these green areas for preserving ecological integrity and providing necessary havens for avian species. The present study presents the first preliminary checklist of avifaunal species within the AIIMS Guwahati campus. A total of 75 bird species were recorded in this study from April 2024 to July 2024. Fifty species were observed in wetland habitat and 40 in built-up areas, with 15 species occurring in both habitats. About 73 species are classified as ‘Least Concern’, and two as ‘Near Threatened’, according to the IUCN Red List. The present study highlights the importance of natural habitats like wetlands, which are more favourable for bird foraging and nesting than built-up areas.
