We radiotracked 13 common cuckoo females in the southeastern part of the Czech Republic. Seven females laid eggs in the nests of reed warblers, Acrocephalus scirpaceus, sedge warblers, A. schoenobaenus, and marsh warblers, A. palustris. We observed 53 nest visits, of which 26 involved egg laying. Cuckoos spent significantly more time within 50 m of the host nest on the laying day than on the 5 prelaying days. The ventage point used when parasitizing or visiting a nest was on average four times further from the nest than the closest possible vantage point, but there was a positive correlation between these two distances.Cuckoos spent on average 20 min observing host nests from their vantage points before they visited a nest.Comparison of cuckoos' visits to host nests with and without egg laying revealed no significant differences in the duration of visits or in other measures of behaviour.
