  1. K denotes the number of parameters in the model, AICc refers to the second order Akaike Information Criterion, ΔAICc shows the difference between the AICc value of a given model and the best-fit model in the set. Variable abbreviations: maxtemp daily maximum temperature, rh relative humidity, mfv/ffv male/female feeding rate (visits/h/chick)
