Abstract :

In this study, 32 bird species from 17 families on the margin of Miangharan wetland were identified. The identification of birds carried out every month in a day from December 2017 to the end of June 2017 by walking along the edge of the Miangharan marsh with the camera and the telescope through direct observation and the total count method. A total of 1,643 birds was counted, with the highest number in February of 386, and the lowest number in June was 209 individuals, and the highest number of birds was 970 in the winter and the lowest population in the spring of 673 birds. The similarity coefficient between the community of terrestrial birds in winter and spring was 95.5% and Euclidean difference was 125.22. The highest evenness was observed in March (0.691) and the lowest evenness was in June (0.448). The most diversity of Margalf, Shannon, and Menhinink were in March, 926/4, 807/1 and 854/2 respectively. Diversity of Whitaker, Harrison and William were zero in between winter and spring bird communities. The t-test showed that there was no significant difference between population and the number of species in both spring and winter seasons with 95% confidence. These studies have shown that the Miangharan wetland, in addition to protecting and maintaining waterbirds in the winter, is also important for the conservation and provides habitats for terrestrial birds and should be considered in its management.
