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.
