Abstract– Birds are well-known bioindicator species and play a vital role in both natural and man-made ecosystems. Garbage dumps provide a variety of food resources for a large number of bird species, which belongs to different feeding guilds. During study, from July 2019 to December 2021, 68 avian species were found feed on household waste, garbage and dump sites in the Abu Road and Mount Abu areas. Out of 68 species, 65 species were categorized as least concerned, two species (Threskiornis melanocephalus and Mycteria leucocephala) near threatened and one species (Ciconia episcopus episcopus) was classified as vulnerable. During study, maximum relative diversity was found in two families: Columbidae and Muscicapidae (RDi= 8.82), followed by three families: Accipitridae, Ardeidae and Phasianidae (RDi= 7.35) and five families, Corvidae, Leiothrichidae, Sturnidae, Threskiornithidae and Turdidae (RDi= 4.41) and the remaining eight families: Ciconiidae, Cisticolidae, Coraciidae, Cuculidae, Dicruridae, Hirundinidae, Pyncnotidae, and Rallidae represent (RDi= 2.94) relative diversity. The remaining ten families (Charadriidae, Falconidae, Laniidae, Leiothrichidae, Motacillidae, Muscicapidae, Passeridae, Psittacidae, Rhipiduridae, Strigidae, and Upupidae) each had only one species and relative diversity (RDi = 1.47) was observed in the study area. During study, most birds belonged to the insectivore (22 species), followed by the omnivore (21), carnivore (17), granivores (7) and frugivores (Psittacula krameri parvirosnis) feeding guild. The highest average number of individuals belonged to the omnivore feeding guild, followed by garnivores, insectivore, carnivore and frugivore.
