Competing models are only reported for autumn departure date. AICc for the null departure date model was 311.1. doy = ordinal day of year. area = sampling area. SeptFullMoon = date of September full moon. Tracks = total number of samples collected. Ind = total number of individuals tracked. Sample sizes include both single- and repeat-tracked birds.
