On November 25, tundra swans were seen flying, frolicking, and foraging on the Donggu Lake. As temperatures steadily dropped in winter season, approximately 3,000 Siberian swans have arrived at the Donggu Lake Wetland Park, a bird habitat in Qu Yuan Management Area, Yueyang City. In recent years, with wetland restoration projects yielding results, an increasing number of migratory birds have chosen to rest here, painting a harmonious ecological picture. (Photo/Cai Xiaoping)
