Acuckoointhenest鸟窝中布谷鸟2/60Swallow燕子Magpie喜鹊Sparrow麻雀Eagle鹰3/60Acuckoointhenest['kuku:]4/6008年奥运会是在哪里举行？鸟巢5/60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鸟类巢中，移走原来那窝蛋中一个，用自己蛋来取而代之。相对于它体形来说，它蛋是偏小，而且蛋上斑纹同它混入其它鸟蛋也非常相同，所以不易被分辨出来。假如不是这么，它蛋必定会被扔出去。布谷鸟鸟蛋比其它鸟蛋早孵化。幼鸟出来后，会立刻把其它蛋扔出巢外。它之所以这么做，是因为它很快就会长得很大，需要吃光养母所能找到全部食物。

一只布谷鸟幼鸟正在由它养母----一只比它小得多刺嘴莺喂食。它需要食物相当于3---4只其养母亲生幼鸟原来需要进食总量。趁其它鸟没看见时，布谷鸟在它们巢中产蛋。它必须非常快速地做完这件事。它蛋有着尤其厚外壳，这么在落入巢中时就不会碎掉了。动物界十大坏妈妈:布谷鸟6/60nest[nest]n.鸟窝，鸟巢theBird'sNest7/60birdwatcher观鸟者engineer[,endʒi'niə]
