Appendix 1—table 3. Statistics for the proportion of a flight with either the experienced or the naïve bird at the front of the pair.

Column 1 reports the generation and sample size. Columns 2 and 3 give the mean and the standard deviation of the proportion of a flight with either the experienced or the naïve bird at the front of the pair. Column 4 reports the results of two-sided paired Wilcoxon signed-rank tests with continuity correction (p-value and V statistic) testing differences between the distribution of the proportion P of a flight for the two birds. Significant p-values are reported in bold.
