A checklist of avian fauna of Suang Reserve Forest, Nagaon, Assam, India with notes on some species of interest

This study presents the first avian checklist from the Suang Reserve Forest of Nagaon, Assam, India. The study conducted between 2018 and 2023 documented 228 bird species belonging to 18 orders and 64 families of which four are globally threatened according to the IUCN Red List. Passeriformes was the most dominant order, with 128 species. Among non-passerines, Piciformes exhibited the highest richness (15 species), followed by Cuculiformes and Accipitriformes (13 species each). The family Muscicapidae had the greatest species diversity (21 species), followed by Accipitridae (13 species), Phylloscopidae (11 species), and Picidae (11 species). We also documented 38 winter visitors and seven summer migrants in the reserve forest. Noteworthy findings included rare sightings of the White-cheeked Partridge and Grey Peacock-Pheasant, and unusual sightings of Wreathed Hornbill and Pacific Golden Plover. The results showed the healthy condition of the forest and its high biodiversity value, despite the study limitations due to inaccessible terrain. We recommend extensive documentation of avifauna and other biodiversity for this region for future conservation planning.
