Abstract:? The avifaunal diversity and density in Anekere wetland, Karkala, Udupi district, Karnataka, India, was studied for a period of three years. Anekere pond inhabits several local and migratory bird species. Reduction in water retention in this pond in summer, weed infestation, variations in food availability in different seasons and threat of predation on the breeding activity of birds affected the avifauna diversity in the study area. This habitat attracted 44 bird species, which are local and migratory including aquatic birds, waders and others. Highest population of tree ducks (lesser whistling teal) was recorded in all the three years of study. Other prominent residents were Moorhens, Jacanas, Herons and Cormorants. The visitors include ringed plovers, wagtails and storks. It was evident that purple moorhen and tree ducks have developed high tolerance to this highly fluctuating habitat and human activity.

Key words: Wetland birds, Avifauna, Anekere, Open bill stork, Mmoorhen, Tree duck
