Season and site were random terms in all models. Bold indicates best-supported models. ^a Number of parameters estimated. ^b Difference in AICc values between each model and the lowest AICc model (we show the list of models until the first one with ∆AIC > 2). ^c AICc model weight. ^d Log likelihood.
