About the Animal
The ‘red crown’ seen in this species is not a crown at all. It is actually an exposed flap of skin used to communicate aggression. By controlling the blood flow to the cap, the crane can cause it to swell.
Red-crowned Cranes are very important to Asian culture. In Chinese, the birds’ name is written like this: 丹顶鹤 ('丹' means 'red', '頂/顶' means 'crown' and '鶴/鹤' means 'crane). The colors red, white and black symbolize vitality, purity and fidelity, respectively. Origami cranes are symbols of longevity and good health. Brides and grooms often exchange crane-shaped gifts before a wedding.
The population of Red-crowned Cranes is between 1,500 and 2,000 worldwide, making this species one of the most endangered cranes in the world. Efforts to re-introduce hand-reared chicks to wild populations have been very successful.
Mating and Reproduction: Like most cranes, this species has an elaborate courtship ‘dance’. The monogamous pair stands side-by-side waving their heads, flapping their wings and leaping into the air. This dance helps to strengthen the pair bond.
The National Aviary in at one time ran a program where U.S. zoos donated eggs which were flown to Russia and raised in the Khinganski Nature Reserve and released into the wild in order to restore wild crane populations. At this time, reintroduction efforts have been put on hold in order to concentrate on other conservation programs that help wild cranes, such as in-situ education and fire suppression.
