The candidate models were ranked in order of increasing difference of AICc (ΔAICc<2); The parameter estimates for males as compared to zero for females. The parameter estimates for adults as compared to zero for juveniles. The parameter estimates in each candidate model are given in columns. β indicates the averaged estimates. ωp indicates the relative importance. ωm indicate the probability that the model is the best approximating model in the set. bc refers to body condition. + indicates this factor variable was included in the model. asterisks refer to the statistical difference (*, P<0.05; **, P<0.01; ***, P<0.001).
