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

Table 1 Table 1 The response of superb fairy-wrens to the playback of cuckoo song (N=149 cuckoo playback experiments) on Kangaroo Island during the (a) opportunistic breeding period (low cuckoo risk) (N=78 trials), and (b) peak breeding period (high cuckoo risk) (N = 71 trials) of the host.

Response variable	Df	F-value	P-value
a) Opportunistic breeding period
No. of Alarm Calls	2	8.67	0.001
Min. Distance to Approach (m)	2	1.01	0.34
Latency to Respond (s)	2	0.61	0.55
b) Peak breeding period
No. of Alarm Calls	2	10.98	0.001
Min. Distance to Approach (m)	2	13.84	0.001
Latency to Respond (s)	2	14.44	0.001

Results are shown for a separate MANOVA test per breeding period: the predictor variable was Playback Stimulus (low risk, moderate risk, high risk cuckoo).
Opportunistic breeding period (low cuckoo risk).
