Example of range-residency verification through variogram analysis. In panel (a), the empirical variogram (black line with light and dark gray shading representing 50% and 95% CIs, respectively) reaches an asymptote for longer lags, suggesting restricted use of space on a continuous timescale. The best-fit model (Ornstein-Uhlenbeck Foraging; OUF) that adequately describes the godwit movement data was fitted via theoretical variogram (red line with pink shading representing 95% CIs). In panel (b), the empirical variogram does not approach an asymptote with long lags, indicating that there is no evidence of range residency. Note the different scales of both axes
