提起杜鹃,大家对它可能并不陌生。不过,你大概不会知道它们耍弄“阴谋诡计”吧。它们自己从不抚养后代,而是把卵产在其他鸟类的巢中,让人家无偿为它孵卵和喂养幼雏。雌杜鹃在产卵前就暗中监视它的未来寄主,不同种类的杜鹃往往选择不同种类的鸟做寄主。当一些勤劳的鸟儿们正忙着筑巢的时候,雌杜鹃就已经盯上了它们,因为它知道这些倒霉的鸟儿快要产卵了。

Mention rhododendrons, we may not be familiar with it. However, you probably will not know that they're playing tricks. Instead of raising their own offspring themselves, they lay their eggs in the nest of other birds, allowing them to hatch their eggs and feed young chickens for free. The female rhododendron secretly monitors its future host before spawning. Different species of rhododendrons often choose different kinds of birds as host. When some diligent birds are busy nesting, the female cuckoo has been eyeing them, because it knows these unlucky birds are about to lay their eggs.
