While in Qiqihar, I also visited the Zhalong Wetlands Nature Reserve where red-crowned cranes are found in abundance in summer. Some of the confined cranes are "performers". Each day at 10.30 a.m. and 2.30 p.m., some cranes will be let out of a pen and they will fly around. On hearing their trainer's calls, they will return to earth and won't stray off. Here they are in flight after being let out.
