Mean distance travelled to forage from roost site, by species and month. Central solid line is the trend in the median values. Dotted lines show the trend in the lower 10th percentile and the upper 80th percentile, which were chosen so that the change in variance can be observed between months, but the median trend can be visually appreciated (see Supplementary Fig. 4 for full distributions of cumulative distances by month). Shaded regions show the season of the year in the southern hemisphere
