Standardized coefficient estimates and compared effect magnitudes of predictors averaged across linear mixed models for five traveling behaviors as response variables: average day to night ratio (A), average daily flight hours (B), median flight height above ground (C), travel speed (D) and straightness (E). Standardized estimates are shown as points, with horizontal lines indicating 95% confidence intervals (CI). Predictors with estimates different from zero (95% CI) are shown in colors, green for spring migration and orange for autumn. Effect magnitudes were compared by dividing the estimated coefficient of each predictor by the sum of all coefficients. Note that age, time spent at previous stopover and precipitation were not included for spring migration, since only adults migrated back to the breeding grounds in this season, the first stopovers at the wintering areas were not possible to estimate from the data and precipitation was removed from spring models to avoid correlation between explanatory variables. Variables are organized in descending alphabetical order
