Fit of foraging movements of Myotis mystacinus to contrasting probability distribution functions. The log likelihood of each fit to each distribution, Akaike information criterion, corrected for sample size (AICc), the Akaike weight and parameters of the best fitting distribution are shown. The Wilcoxon fit (w) statistic is presented for the distribution of best fit, shown in bold.
