As November unfolds, the wetlands along Qidong's Yangtze River estuary are transforming into vibrant hubs for migratory birds. Black-tailed gulls, Siberian gulls, relict gulls, dunlins, and sanderlings flock to these wetlands, joined by ducks—particularly active spot-billed ducks—at the Qidong Riverside Wetland. Under warm sunlight, the birds glide, land, and create ripples across the water's surface.

Situated along the East Asia–Australasia migratory route, Qidong serves as a critical waypoint for migratory birds. Its diverse habitats, including tidal flats, aquaculture ponds, woodlands, and farmlands, provide abundant food sources like fish and benthic organisms. These ideal conditions make Qidong a key wintering ground for rare species such as relict gulls, black-faced spoonbills, and Chinese egrets. 

From November through February, migratory birds find refuge in Qidong before beginning their northward migration. Biodiversity monitoring in the area has recorded 178 bird species, representing over 60 percent of Nantong's total avian species. 

Beyond its unique landscapes, Qidong's commitment to improving its environment has been pivotal. Boasting five consecutive years as Jiangsu's leader in air quality, Qidong continues to draw migratory birds to its shores, cementing its reputation as a sanctuary for these winged travelers.
