Mother ID was included as a random effect in all models. Models with ΔAIC ≤ 2 are supported. See File S2 for a complete list of model results. (Model parameters are sex of offspring (offsex), age of offspring (offage), maternal age at the time of offspring birth (momage_corr), habitat type at the natal site (momhab), habitat type at the settlement site (offhab), harvest density at the natal site (momharv), harvest density at the settlement site (offharv), habitat suitability rank at the settlement site (offhs), and habitat suitability rank at the natal site (momhs), * indicates an interaction).
