Egg mimicry by the Pacific koel: mimicry of one host facilitates exploitation of other hosts with similar egg types

Abernathy, Virginia; Troscianko, J.; Langmore, Naomi


When brood parasites exploit multiple host species, egg rejection by hosts may select for the evolution of host-speci c races, where each race mimics a particular host’s egg type. However, some brood parasites that exploit multiple hosts with the ability to reject foreign eggs appear to have only a single egg type. In these cases, it is unclear how the parasite egg escapes detection by its hosts. ree possible explanations are: 1) host-speci c races are present, but di erences in egg morphology...[Show more]
