Table 2 (a) Top models with ΔAICc < 4.0 for factors that influence nestling survival in Eurasian kestrels (successful nests only). (b) Model-averaged coefficients from a set of 7 models with ΔAICc < 4.0 (cumulative ωi = 0.53) presented as estimated values ± (unconditional) SE, lower and upper 95% CIs, N containing models and relative variable importance (RVI); confidence intervals of parameter estimates not including zero in bold
