Tumuji National Nature Reserve in NW China an important "transit station" for migratory birds

The Tumuji National Nature Reserve of the Xing'an League in north China's Inner Mongolia Autonomous Region has become a "transit station" for many birds on their migratory path, including swans, ruddy shelducks, bean gooses, red-crowned cranes, and oriental storks. In recent days, tens of thousands of migratory birds have arrived at the reserve for a temporary stopover.
