3: (1.62). Likewise, bird species richness in the area was normally distributed and significantly different (P<0.05) among the three sites. Site 1 had the highest number of bird species richness (16.36) (Species diversity is different species of birds at the site, while species richness is referring to specific species population), compared to site 2: (14.32) and site 3: (11.51). It was observed that there is a significant relationship between vegetation density and bird species diversity, because as tree
density increases, diversity of bird species decreases. Therefore, there is a significant relationship between vegetation density and bird species diversity. A total of 135 bird species in 40 families was recorded during the survey. Seventy-four percent were found in site1, sixty-three percent in site 2 and seventy-one percent in site 3. The majority of wetland birds observed during this study were resident (Ardeidae family), migratory (Accipitridae family) and palearctic species (Yellow Wagtail, Warblers,
Northern Shoveler and Sandpipers). It can be concluded that wild birds are good indicators of environmental condition, revealing the state of the wetland. Some sites were more disturbed, as observed in site 1 and site 3. It was, however, recommended that regular monitoring of the sites should be carried out so as to control changes in the state of the wetland ecosystem.
