Illustration of polar bear behavior and movement. Polar bear track drifting \(\approx 15^{\circ }\) relative to wind (gray) when stationary on sea ice (e.g., when still-hunting by breathing hole; blue), moving \(\approx 90^{\circ }\) relative to wind during olfactory search (red) to maximize probability of encountering odor plumes (purple), and random movement relative to wind during area-restricted search (purple track).
