The relative importance of significant physiological and social predictors of the propensity to initiate a foraging bout.

The table shows the summed ω (∑ω), the number of models in which the variable appears (Models), and the relative ω, which is calculated by dividing ∑ω with the proportion of all models in which the variable appears. Shown are also the ∑ω for all models representing physiological and social factors determining leadership, the number of models in the model set representing these factors, and their relative ω. Abbreviations: active foraging time, AF; female structural size, FS; annual body condition, AC; female spatial position, SP; relative aggressiveness, AG.
