The study of bird species diversity and richness in Dagona-Waterfowl sanctuary was carried out in early wet and late dry seasons. This was to provide some information on the wild birds of the sanctuary. Dagona sanctuary is located within the Bade-Nguru wetland sector; it is one of the important bird areas strategized for the conservation of avifauna species in Sub-Sahara region, Nigeria. Line transect method was used to carry out birds’ survey at three different lake sites, namely: Gatsu (Site:1), Mariam (Site: 2) and Oxbow (Site: 3). The data were analyzed with the Kolmogorov- Smirnov test to determine the distribution level of the birds. The birds’ diversity was assessed using Shannon-Weiner diversity index. The results showed that bird species diversity was not equally distributed in the sites Site 2 had the highest diversity with an index of 2.74 compared to Site 1 with 1.84 and Site 3 with 1.62. Likewise, bird species diversity in the area was normally distributed birds’ abundance were significantly different (P |
