Table 2. Models obtained to assess the effects of individual sex, season and population on the movement and spatial segregation patterns of 127 GPS-tagged griffon vultures in Spain. The null model was included in our set of models. k: number of parameters; AICc: Akaike Information Criterion corrected for small sample sizes; ΔAICc: difference between the AICc of model i and that of the best model (i.e. the model with the lowest AICc); w: Akaike weight. For each best model, variability (as a percentage) explained by the fixed and random predictors (R2) are shown. The best models (ΔAICc<2) are highlighted in bold.
