The Horsfield's bronze-cuckoo (Chaldtes basalis) egg closely matches the appearance of its host fairywren (Malurus spp.) eggs. Mimicry of host eggs by cuckoos is usually attributed to coevolution ...

ON the morning of May 25 I found a nest of the reed bunting (Emberiza schoeniclus) with a cuckoo's egg in it besides three eggs of the bunting itself. When I took some friends to see it two or three ...
