Body positions were estimated for grazing and resting red and roe deer (direct observations) or from snow tracks of resting animals (beds). The mean vector is characterized by its angle (μ) and its length (r). Values in parentheses below the mean vectors represent the 99% confidence intervals (with reference to north only).
