Abstract
The present study aimed to assess the avian diversity of Mohoriya wetland located in the Darrang district of Assam which provides shelter and breeding ground to many resident and migratory birds. The survey was conducted from November 2023 to May 2025. A total of 57 species of bird species belonging to 12 orders and 21 families have been recorded from the study area. Out of them 65% have been recorded as resident, 26% were migratory and 9% have been recorded as local mover. Four birds viz. Leptoptilos javanicus, Vanellus vanellus, Anhinga melanogaster, Circus macroureus were listed as near threatened and Aquila nepalensis as endangered species as per IUCN red list.Various anthropogenic activities such as large scale habitat use, agricultural extension,use of pesticides, hunting of birds, are the major threats to survival of avian species.
