Abstract:
This study was conducted from July 2018 to July 2019 at a rate of two visits per month at Lake Dam 16 th Tishreen. The results showed the presence of a small diver, Tachybaptus ruficollis, in the study areas (floating cages, reservoir).As a result of monitoring and paint counts at the two sites selected from the Lake. We recorded 500 individuals of Tachybaptus ruficollis from them 355 and 145 from the first and second sites, respectively, and the recorded Tachybaptus ruficollis the highest frequency rate around the floating cages. The numbers of recorded bird species varied according to the months of the year, from 12 individuals from November to 155 in May while absent in February 2019. Some ecological coefficients (Species richness factor, variation factor) was studied where it was found that its numbers were more variable and therefore less stable in the basin area with a different coefficient (6.20), and it appeared that May 2019 is the highest number of this bird with a Richness factor of 227.12.
