Mean predicted values with 95% confidence interval for differences in daily time span between activity onset and civil dusk (TSdusk) of eight hedgehogs between the pre-festival and festival phases. Negative values represent a shift in activity to a later time of the day during the festival, while positive values represent a shift in activity onset to an earlier time of the day during the festival. We consider all differences to be significant where the confidence interval does not include 0. Six out of eight individuals show a significant positive shift.
