摘　　要：Birds play a vital role in monitoring ecosystem health and biodiversity because they are relatively easy to observe and have been extensively studied. However, ongoing threats such as habitat destruction, fragmentation, and environmental changes have significantly impacted their populations and distribution patterns. This study focuses on assess the variety and relative richness of bird species at Eastern Al Dabasin Bridge in Khartoum, Sudan, as well as evaluating their current conservation status furthermore examines human activities impacting bird populations. Monthly surveys, conducted using the Point Counts method across wet and dry seasons between 7:00 a.m. and 10:00 a.m., documented species counts and locations. Identification utilized visual characteristics such as size, color, and vocalizations. A total of 3708 birds, representing 80 species from 17 orders and 41 families, were recorded. The most frequently observed species were the House Sparrow, Spur-winged Lapwing, Greater Blue-eared Starling, Laughing Dove, and Black Kite. Bird abundance peaked in June and December, with richness affected by seasonal and environmental conditions. All species observed were classified as Least Concern, underscoring the importance of conservation and sustainable management to protect local biodiversity and safeguard the long-term viability of bird populations in the area, it is essential to adopt a holistic approach to environmental management. This should include measures for pollution reduction, habitat rehabilitation, and the promotion of community education on the importance of conservation.Birds play a vital role in monitoring ecosystem health and biodiversity because they are relatively easy to observe and have been extensively studied.
