About These Birds
Common Crane
灰鹤（约5公斤）是欧洲和亚洲最具代表性的大型鸟类之一，具有灰色羽毛、红色冠和黑白色头部图案。繁殖于北欧至西伯利亚，迁徙至南欧和非洲北部越冬。在冬季田野中大群觅食。无危；因保护措施得力，种群数量稳步回升。
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
