Host response to cuckoo song is predicted by the future risk of brood parasitism

Table 2 A single model test of the response of superb fairy-wrens to the playback of cuckoo song (N=149 cuckoo playback experiments) on Kangaroo Island

The predictor variables were playback stimulus (low risk, moderate risk, high risk cuckoo) and breeding period (peak, opportunistic). Playback ID and Study Site were entered as random effects.
