Core Viewpoint - The article highlights the unique collective foraging behavior of the spoon-billed sandpiper at Hengshui Lake, showcasing the ecological significance of the area for migratory birds and the successful conservation efforts that have improved the habitat [1][3]. Group 1: Ecological Significance - Hengshui Lake is a national nature reserve that maintains a complete wetland ecosystem, including marshes, water bodies, mudflats, meadows, and forests, playing a crucial role as a stopover and energy replenishment station for migratory birds along the East Asia-Australasia flyway [3]. - The area has recorded 337 bird species, with over 60 species wintering annually, peaking at more than 100,000 individuals [3]. Group 2: Conservation Efforts - Recent conservation measures, including ecological water replenishment, shoreline restoration, and the release of aquatic species, have led to continuous improvements in water quality and significant increases in aquatic biodiversity [3]. - The unique ecological environment of open shallow water areas provides optimal foraging conditions for the spoon-billed sandpiper, facilitating their distinctive collective foraging strategy [3].
