Mute swan cygnets are set to hatch at North Longhu Wetland Park in Zhengzhou City in central China's Henan Province.
The mute swan is less vocal than other swan species, hence the name. The park has become an ideal destination for migratory birds to breed because of an improved environment. Over the past two years, the number of mute swans in the park has reached 33.
