Wetlands provide organisms with a diverse range of breeding sites and food, allowing them to survive during the non-breeding season. Despite the hotspot area, the waterbird fauna in the suburbs of Asmara city is poorly described. Information on the seasonal variation in species diversity and abundance is generally patchy. The study described the seasonal change in waterbird species diversity and abundance in different locations with varying physiological and ecological conditions. Waterbirds usually congregate around open wetlands, hence their abundance is more appropriately determined by counting all individuals in the congregate. The direct total area count method was implemented, and data was collected both during the dry (January-March) and wet (July- September) seasons of the year 2020. Species similarity between the study sites was calculated using The Morisita- Horn index (CMH). A total of 5641 waterbirds were counted, representing 12 families and 47 species. The study shows a significant difference (p |
