肯尼亚山林里有一种鸟,叫乌紫(zi)鸟,这种鸟因为全身暗紫色而得名。每当春季来临时,乌紫鸟便开始搭窝(dawo)筑巢(zhu chao),繁育后代。刚开始,它与其它鸟儿的繁育没有什么区别,可当它的幼鸟长到一定程度的时候,这种鸟便展示出与别的鸟类不一样的特性。 There is a bird in the woods of Kenya, called the zi bird, which is named for its dark purple color. Whenever the spring comes, the Uvula beetle begins to daw nest (zhu chao), breeding offspring. At first, it is no different from the breeding of other birds. When its young birds grow to some extent, the birds exhibit different characteristics from other birds.
