Migration is a critical ecological process for birds. Understanding avian migratory routes is essential for identifying important stopover sites and key foraging areas to ensure high-quality stopovers for birds. The Black-faced Spoonbill (), a national Grade I protected wild animal in China, is classified as endangered on the IUCN Red List of Threatened Species. Studying the migratory routes of the Black-faced Spoonbill and identifying critical stopover sites across different life histories is vital for its conservation. However, research on the migratory routes of this species has been very limited. This study, utilizing citizen science data and the Level-order-Minimum-cost-Traversal (LoMcT) algorithm, reconstructs the migratory trajectories of the Black-faced Spoonbill from 2018 to 2022. The results show that Wenzhou, Xiamen, Shantou, Shanwei, Hsinchu, Chiayi, and Tainan are significant stopovers for this species. The Black-faced Spoonbill is actively migratory during the migration season across the southeastern coastal region of China. The simulation results of this study reveal the migratory routes and activity patterns of the Black-faced Spoonbill, providing critical support for its conservation.
迁徙是鸟类重要的生态过程。了解鸟类迁徙路线对于确定重要的中途停歇地和关键觅食区域至关重要，以确保鸟类有高质量的中途停歇。黑脸琵鹭是中国国家一级保护野生动物，在国际自然保护联盟濒危物种红色名录中被列为濒危物种。研究黑脸琵鹭的迁徙路线并确定其不同生命历程中的关键中途停歇地对其保护至关重要。然而，关于该物种迁徙路线的研究非常有限。本研究利用公民科学数据和层次顺序最小成本遍历（LoMcT）算法，重建了2018年至2022年黑脸琵鹭的迁徙轨迹。结果表明，温州、厦门、汕头、汕尾、新竹、嘉义和平南是该物种的重要中途停歇地。黑脸琵鹭在迁徙季节活跃于中国东南沿海地区。本研究的模拟结果揭示了黑脸琵鹭的迁徙路线和活动模式，为其保护提供了关键支持。
