Models with highest the probability (Δ AICC < 2) assessing variation in the corncrake males’ response to playback during eavesdropping and intrusion phase of experiments.

The Akaike weight (wi) was calculated on the basis of Akaike’s Information Criterion corrected for small sample size. Predictors included: Treatment; Day of season; Hour after sunrise; Rhythm of call before the playback start. Estimates with standard errors and significance for predictor variables used in GLM models with highest probability (Δ AICC
