The focus of the present study was to investigate factors responsible for high variation in timing of host egg rejection. We presented a cuckoo dummy near great reed warbler nests and experimentally parasitized the clutches with a nonmimetic egg. Immediately afterward, we video recorded host behavior to determine egg ejection times. We fitted a regression tree model with the timing of egg ejection as a dependent variable and female-related characteristics as explanatory variables. Only female behavior toward the foreign egg proved to have a significant effect on the timing of egg ejection. Females devoting more time to clutch inspection ejected the egg more quickly than females inspecting their clutches only briefly. We discuss our results in the context of known intra- and interspecific differences in host response times toward alien eggs and cognitive mechanisms involved in host egg discrimination processes.
