Average distance of pumas from bighorn sheep kill sites as a function of time. Average distance of pumas F7, M5, and M6 from 22 bighorn sheep kill sites as a function of time in the Peninsular Ranges of southern California, USA, January 2002-September 2004. Error bars show standard deviation of distance. Data are normalized to time of kill detection (t = 0) for comparison. The mean plus 1 standard deviation of time spent at a kill site was found in this study to be 138 h (5.7 days). This was used to bound the before, during and after kill timeframe analyses for comparison.
