About These Birds
Demoiselle Crane
The demoiselle crane is the smallest crane species but undertakes one of the most grueling migrations, crossing the Himalayas at altitudes over 8,000 meters to reach wintering grounds in India. Named for its elegant appearance by Marie Antoinette, it is the second most abundant crane species in the world.
Emperor Penguin
体型最大、最重的企鹅。在南极冬季零下60摄氏度的环境中繁殖。雄鸟孵卵约65天，期间完全禁食。
