This study is a work of memory that we conducted with a view to obtaining a bachelor's degree in science at the Official University of Bukavu. This study was carried out at Lake Kivu in the Ishungu basin on Ibindja Island and at Birava, during a period from March 19 to July 28, 2010. The inventory of birds was carried out at seven sites, including five in Ibindja and two other sites in Birava. Data collection was done by Japanese net capture, observation with a pair of binoculars and with the naked eye and by counting. Birds captured and / or observed were identified using the bird identification guides of Zimmerman, D.A., and al (1999) and Sinclair, I., (2003). This work made possible to inventory several individuals of birds grouped into 6 orders, 12 families, 23 genuses and 32 species of birds. The abundant species are: Ceryle rudis, Phalacrocorax carbo and Phalacrocorax africanus with respectively 30.72%; 25.41% and 15.47%. The Passeriformes order represents only half of the inventoried families, or 50%. The Ardeidae and Ploceidae families represent a large number of genuses, 26.08% and 21.73% respectively. The genus Ploceus alone contains 12% of the identified species. The highest number of species was observed in June and the lowest in July, which was also the last month spent in the field. The similarity quotient in bird species between these two environments (Ibindja and Birava) is 72%. Among the seven sampling sites chosen, the Bwalimu site is more diversified (H = 2.257), but the Chabatalima site is more rich in species with 21. Recommendations and suggestions are given for the sustainable protection not only of aquatic birds but also of the environments in which they live.
