アオカケスは鮮やかな羽毛と大きな鳴き声で知られるカラス科の大胆で知能が高い鳥。アオカケスは毎秋数千個のドングリを蓄えることでカシの木の重要な散布者となっている。複雑な社会的行動には、給餌器から他の鳥を追い払うためにタカの声を真似ることも含まれる。
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.
