Site details


Site description: Located in the north of Burundi, immediately north of the town of Kirundo close to the Rwandan border, Lake Rwihinda, known in the past as Lac aux Oiseaux (Bird Lake), lies a little way upstream of the Akanyaru wetlands (RW005), to the north-west. The area of the lake is 425 ha, but the total protected area has been extended to cover 8,000 ha.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas)
Additional biodiversity: See Box and Table 3 for key species. In the past, this site held large numbers of breeding Phalacrocorax carbo, Anhinga rufa, Egretta ardesiaca, Ardea melanocephala and Nycticorax nycticorax. Large numbers are rarely observed today, however, due to decreasing water-levels, fishing and agriculture. There are records of Ardeola idea, Circus macrourus, Falco naumanni and Gallinago media. In addition, one species of the Guinea–Congo Forests biome, five of the Afrotropical Highlands biome and two of the Zambezian biome have been recorded, while a third, Calamonastes undosus, used to do so, but is now possibly extinct locally due to habitat loss (see Table 3). Indeed, the current status of a number of species at Rwihinda is uncertain. Non-bird biodiversity: None known to BirdLife International.
Delineation rationale: The main threat for Rwihinda is the agricultural extension.
