Abstract

Landscape changes due to habitat alteration and fragmentation can result in complex changes in biodiversity. In the present study, Narsinh Mehta Lake located on the center of Junagadh city was studied for avian diversity during March 2021 to December 2022. The lake, a vital ecosystem within an urban setting, presents a unique opportunity to investigate how avian species composition and abundance are influenced by various water quality parameters. A total of 85 avian species belongs to 14 orders and 36 families and 69 genera are recorded including 5 near threatened and 3 vulnerable species. Amongst the recorded species, 22 were migratory and 63 resident birds. The carnivorous feeding habit was shown by the maximum number of species while nectarivores and frugivorous bird species were in the least numbers. The rich avifaunal diversity of Narsinh Mehta Lake confirms it as a suitable habitat for both migrant and resident bird species. Furthermore, variations in water parameters appear to influence the distribution and behavior of avian species, highlighting the importance of maintaining suitable water conditions for avian populations. Such insights are critical for effective conservation and management strategies aimed at preserving both avian diversity and the integrity of Narsinh Mehta Lake ecosystem. It is worth to mention that the lake is selected for beautification to attract tourists which may affect the biodiversity of the lake.
