Home range and distance estimates for nine Cape vultures tracked by GPS-GSM units.

Minimum convex polygons (MCP) including all recorded GPS locations and 99% contours from kernel density estimation (KDE) represent overall foraging ranges. 50% KDE contours represent core foraging ranges. Mean (± SD) and maximum distances between consecutive GPS locations, and the total distance travelled divided by the number of tracking days are shown. The age (adult (>5 years), immature (2–5 years) or juvenile (first year)) of each vulture, the tracking period and number of GPS locations (number of stationary (−1) locations are given in parentheses) recorded are also shown.
