Abbreviations: AICc, bias-adjusted Akaike’s Information Criteria values;wi, AICc weights; R2adj, R-squared adjusted; gdf, goodness-of-fit; CRP, duration of the chick rearing period.aScaled ΔAICc; ΔAICc = 0.00 is interpreted as the best fit to the data among the models.bWeight of evidence interpreted as a proportion. Weights across all models sum to 1.00.
