Number of parameters (K), negative log likelihood (LL), difference between the best model and given model (ΔAICc), and AICc weights (wi) are provided. Covariates shown include study site (SITE), cumulative precipitation in spring (P1.CP) and brood-rearing period (P4.CP), brood-period seasonal index (P4.SIND), brood-period number of growing degree days (P4.GDD), and brood-period cumulative precipitation (P4.CP).
