Abstract

• Avifauna was investigated in four study sites of the Pakokku environs during July 2015 to June 2016. A total of 126 bird species belonging to 81 genera, 41 families and 16 orders were recorded. Of these, 35 species were water birds and 91 species were terrestrial birds. The bird species were represented with 25 migrants and 101 residents. During the study period, two endemic species, namely Turdoides gularis (White-throated Babbler) and Mirafra microptera (Burmese Bushlark) were recorded. The highest species composition was found in order Passeriformes (51.59%, 65 species), followed by Pelecaniiformes (8.73%, 11 species). Relative abundance indicated six species as very common, 10 species as common and 110 species as uncommon in Pakokku environs. In the study area, the highest species richness and diversity values were evaluated in Site I (d =11.643, D= 0.077, H'= 3.199) and Site III (d= 10.934, D= 0.039, H'= 3.646). This situation may be related to the habitat conditions and availability of food sources. Pakokku environs may be considered rich in bird diversity due to occurrence of high number of bird species and individuals.
