鹰是寿命最长的鸟类之一,甚至与人类寿命相差无几。但它们活到中年时,爪子就开始老化,喙也变得又长又弯,因为羽毛长得又浓又厚,翅膀变得十分沉重,飞翔十分吃力。它只有两种选择:等待死亡或经过痛苦的更新过程。于是它们会努力地飞到山顶,在悬崖上筑巢,用喙击打岩石,直到完全脱落,然后静静地等候新的喙长出来,再用新长出的喙把指甲一根一根拔出来,当新指甲长出来后,它们便把羽毛一根一根拔掉。5个月以后,新的羽毛长了出来,它们获得了新生! Eagles are one of the longest life birds, even with human life almost the same. But when they live in middle age, their paws begin to age, and their beaks become long and curved, because their feathers grow thick and thick, their wings become so heavy they fly very hard. It has only two options: waiting for death or painful renewal. So they flew hard to the top of the mountain, built nests on the cliffs, beat rocks with beaks until they were completely detached, and then quietly awaited new beaks to grow and nails one by one with newly grown beaks When the new nails grow out, they pluck the feathers one by one. Five months later, the new feathers grow, they have a new life!
