As winter sets in and cold winds sweep southward, Yueyang, a city rich in wetland resources in Central China's Hunan province, once again becomes a bustling stopover for migratory birds.
Recently, more than 700 tundra swans from Siberia have arrived at the Donggu Lake wetland in Yueyang. The birds were seen gliding across the water in small groups, dipping their beaks into the ripples.
In addition to the swans, 34 species of wintering birds have been recorded at Donggu Lake this season. According to the wetland administration, more than 61 bird species have been documented in recent years, including seven national first-class protected species such as the Siberian crane and the oriental white stork. Each year, the total number of migratory birds passing through the area exceeds 100,000.
The best time to observe the birds at Donggu Lake is from November to March, the administration said. As temperatures continue to drop, more species are expected to arrive.
