在北美,关于鹰,有这样一个古老的传说。它是世界上寿命最长的鸟类,据说可以活到70岁,但在40岁时,它的爪子开始老化,无法捕猎;它的喙变长变弯,影响进食;它的羽毛变浓变厚,难以飞翔。于是,留给它的只有两种选择:等死或者经过一个十分痛苦的蜕变过程。它需要一个隐秘的悬崖,摔断喙,拔掉爪子,再褪去陈旧的羽毛,历时五个月的磨难才能获得30年的命。 In North America, there is such an ancient legend about eagles. It is the longest-lived bird in the world and is said to live to be seventy years old, but at the age of forty, its paws begin to age and fail to hunt; its beak becomes longer and becomes curved, affecting its feeding; its feathers become thicker Thick, hard to fly. Thus, leaving it with only two options: to die or undergo a very painful transformation process. It requires a steep cliff, broken beak, unplugged paw, and then faded old feathers, which lasted five months of hardship to get 30 years of life.
