Heralding the dawn of winter, flocks of migratory swans have arrived to spend their wintertime in a wetland in north China's Inner Mongolia Autonomous Region.

Swan is a genus of seven bird species, of which three migratory species could be found in China.

Every winter, these birds fly thousands of kilometers to find wintering grounds in China from their breeding grounds in Russia and Mongolia and return after the arrival of spring.
