From: Arctic avian predators synchronise their spring migration with the northern progression of snowmelt

(a) An example of the stratum in the step selection function with chosen and alternative locations and the snow cover background. (b) The impact of snow cover (0-snow absence, 1-snow presence) on movement preference (0-alternative vs 1-chosen locations) of arctic raptors during the spring migration at steps separated by one day (Table 3). Shaded areas represent SE of the model estimates.
