Fig 6 — Bar graphs showing the straight-line distance (upper graphs) and the actual distance traversed (lower graphs) for Matriarch 1 (left graphs) and Matriarch 2 (right graphs) on each day between the sites where the major sleep episode occurred. The straight-line distance between the locations of the main sleep episodes for Matriarch 1 averaged 6.8 km (s.d. = 7.3 km; range = 0.8–34.3 km) and for Matriarch 2 averaged 6.9 km (s.d = 7.4 km; range = 0.5–29.1 km). The actual distance travelled between each sleep location between main sleep episodes averaged 15.1 km (s.d. = 10.8 km; range = 5.1–54.9 km) for Matriarch 1 and 17.3 km (s.d. = 9.9 km; range = 7.7–51.5 km range) for Matriarch 2.
