外行总结 我们研究了悲伤杜鹃和它们常见的裁缝鸟宿主之间蛋外观的匹配，这两种鸟都进化出了带有棕色斑点的蓝色和白色蛋。裁缝鸟排出了所有与自己的蛋不同的实验蛋，但接受了几乎所有属于其相应形态的蛋。我们提供的证据表明，悲伤的杜鹃根据寄主蛋的外观随机产卵，并且它们不会选择性地选择寄主巢穴以最大限度地提高蛋的匹配和接受度。
Lay Summary We studied the matching in egg appearance between plaintive cuckoos and their common tailorbird hosts, both of which have evolved blue and white eggs with brownish spots. Tailorbirds ejected all experimental eggs that differed from their own eggs but accepted almost all eggs belonging to their corresponding morphs. We provide evidence that plaintive cuckoos lay eggs randomly with respect to host egg appearance and that they do not selectively choose host nests to maximize egg matching and acceptance.
