A group of black storks, a migratory bird species under first-class national protection in China, arrived in groups at the urban section of the Yuhe River in Datong City, north China's Shanxi Province, on Saturday during their southward migration.
Black storks are long-distance migratory birds with strict habitat requirements.
They serve as an important "ecological indicator" for assessing regional ecological quality and aquatic environmental conditions.
The Yuhe Wetland, with its rich waterways and abundant fish and shrimp, provides an ideal resting area for them during their southward migration.
The black storks will stay in the region to replenish their energy before continuing their migration.
