  1. Parameters were chosen using AICc for each response variable separately (scaled mass index, B-hydroxybutyrate BUTY, triglyceride TRIG, final winter site feather corticosterone CORT f . Scaled mass index and time at capture were added as additional covariates for BUTY and TRIG models (see “Methods” section). All covariates were standardized prior to analyses such that effect sizes were comparable
