“…This was followed by Anseriformes (n=16 species) Charadriiformes (n=12 species), while Podicipediformes and Strigiformes order were least represented by one species each (Table 1). Similar results were found by other studies, highlighting the dominance of the Passeriformes order as the primary avian taxa in Bhindawas Bird Sanctuary, Sultanpur National Park, Dighal wetlands Haryana (Singh et al, 2019;Singh et al, 2021 andParul andKumar, 2023). The analysis of relative diversity revealed Anatidae (16 species, RDi =12.40% ) as the most dominant family, followed by Muscicapidae and Ardeidae (8 species, RDi =6.20%); Acciptridae (7 species, RDi = 5.43%); Columbidae, Motacillidae and Scolopacidae (6 species each, RDi = 4.65%); Cuculidae (5 species, RDi = 3.88%); Rallidae, Leiothrichidae and Sturnidae (4 species each, RDi = 3.10%); Ciconiidae, Phalacrocoracidae, Cicticolidae and Threskiornithidae (3 species each, RDi = 2.33 %); Charadriidae, Alcedinidae, Meropidae, Phasianidae, Corvidae, Hirudinidae, Laniidae, Jacanidae, Estrildidae, Ploceidae and Psittacidae (2 species each, RDi = 1.55 %).While families with the least relative diversity (1species each, RDi = 0.78%) were represented by Pandionidae, Bucertidae, Upupidae, Recurvirostridae, Coraciidae, Acrocephalidae, Josteropidae, Monarchidae, Passeridae, Paradoxonithidae, Phyloscopidae, Vangidae, Rostratulidae, Anhingidae, Dicruridae, Nectariniidae, Pycnonotidae, Megalaimidae, Picidae, Podicipedidae, Strigidae (Table 2).…”
