Whooper swans swoop into nature reserve

More than 5,000 whooper swans have arrived at Rongcheng Swan National Nature Reserve in Weihai, Shandong province, to spend the winter, the reserve said on Sunday.

To make sure the swans have enough food, workers spread corn for them every day.

The swans stay for about five months at the bay in Rongcheng, making it one of the largest wintering grounds for whooper swans in the world.
