老鹰是世界上寿命最长的鸟类。它一生的年龄可达70岁。要活那么长的寿命,它在40岁时必须做出艰难却重要的决定。当老鹰活到40岁时,它的爪子开始老化,无法有效地抓住猎物。它的喙变得又长又弯,几乎碰到胸膛。它的翅膀变得十分沉重,因为它的羽毛长得又浓又厚,使得飞翔十分吃力,它只有两种选择:等死,或经过一个十分痛苦的更生过程。这个过程长达150天,它必须很努力地飞到山顶。在悬崖上筑巢,停留在那里,不得飞翔。老鹰首先用它的喙击打岩石,直到完全脱落。然后静静地等候新的喙出来。它会用新长出的喙把指甲一根一根地拔出来。当新的指甲长出来后,它们便把羽毛一根一根地拔掉。5个月后,新的羽毛长出来了。老鹰开始飞翔,它获得了新生,可以再过30年!
The eagle is the longest living bird in the world. It lives up to 70 years of age. To live that long life, it must make tough but important decisions at the age of 40. When the eagle lived until the age of 40, its paws began to age, failing to effectively catch the prey. Its beak became long and curved, almost touching the chest. Its wings became heavy because its feathers grew thick and thick, making it extremely difficult to fly, with only two options: to die, or to go through a very painful renaissance. The process, which took as long as 150 days, must fly hard to the summit. Nest on the cliff, stay there, not fly. The eagle first hits the rock with its beak until it is completely detached. Then quietly waiting for the new beak to come out. It will pull out the nails one by one with the new beak. When new nails grow, they pluck their feathers one by one. Five months later, new feathers grow. The eagle started to fly, it gained a new life, can be another 30 years!
