(a) We list all models whose ΔAICc ≤ 2, null model, and present AICc weight, number of parameters (No. par.), twice the negative log likelihood (− 2LL) and estimated occupancy rate (ψ). (b) Summed model weight of each site covariates in the equivalent models. The key for the covariate codes used is given in Table 1
