Table 6 Sets of candidate models explaining between-year density similarity (Renkonen’s index) of birds wintering in an urbanized environment (Kraków, S Poland; for parameters, see Table 1). The number of variables (K), Akaike’s information criterion for small samples (AICc), the difference between the given model and the most parsimonious model (ΔAICc) and the Akaike weight (w) are reported for each model
