About 380 captive-bred red-crowned cranes have been released into the wild by the Zhalong National Nature Reserve, known as the "home of red-crowned cranes" in China.

The reserve has been exploring ways to train the captive-bred cranes for release into the wild, in a bid to raise the crane population with a healthy genetic pedigree.

Established in 1979, the reserve has successfully released about 380 captive-bred red-crowned cranes into the wild.
