And since we are all on computers you might try a simple web search. I just typed "Yellow-billed Cuckoo parasitism" into Google and came up with several billion sites. One of the first stated this. >>>>Breeding normally coincides with that of the cicada and/ or tent caterpillar. Studies have shown that in times of prey abundance, production of eggs will increase, which leads to an increase in brood parasitism by Coccyzus americanus. (Lasley & Sexton) (Wolfe) Brood parasites are defined as species that do not build their own nests or raise their own offspring. By increasing the clutch size and synchronizing hatching with periodical cicada eruption further increases the occurrence of brood parasitism. This positive reproductive response to the increased abundance of prey indicates exceptional adaptive value. This plasticity is a regular aspect of Coccyzus americanus breeding biology.
