Acuckoointhenest鸟窝中的布谷鸟Swallow燕子Magpie喜鹊Sparrow麻雀Eagle鹰Acuckoointhenest['kuku:]08年奥运会是在哪里举行的？鸟巢布谷鸟准备产蛋了，但它却不会自己筑巢,它会来到像那些比它小的鸟类的巢中，移走原来的那窝蛋中的一个，用自己的蛋来取而代之。相对于它的体形来说，它的蛋是偏小的，而且蛋上的斑纹同它混入的其他鸟的蛋也非常相似，所以不易被分辨出来。如果不是这样，它的蛋肯定会被扔出去。布谷鸟的鸟蛋比其他鸟蛋早孵化。幼鸟出来后，会立刻把其他的蛋扔出巢外。它之所以这样做，是因为它不久就会长得很大，需要吃光养母所能找到的全部食物。

一只布谷鸟的幼鸟正在由它的养母----一只比它小得多的刺嘴莺喂食。它需要的食物相当于3---4只其养母亲生的幼鸟本来需要进食的总量。趁其他鸟没看见时，布谷鸟在它们的巢中产蛋。它必须非常迅速地做完这件事。它的蛋有着特别厚的外壳，这样在落入巢中时就不会碎掉了。动物界的十大坏妈妈:布谷鸟NewWordsandExpressions:
