(Unconditional parameter estimates, standard error, confidence intervals and relative importance (RI) of tested predictor variables for bihourly displacement distances, using two top candidate models (ΔAIC_c < 2). Predictor variables shown include month, time of day, distance from water source, total rainfall, and mean temperature)
