Models are ranked by differences in Akaike’s information criterion and only candidate models within ΔAICc d ≤ 4.0 are presented. Model selection results are followed by model averaging results for each species. The R2 represents the model fit for the estimated mean daily depth use vs. model averaged predicted values.
