As a preliminary study, we used the GPS location data (May - September 2004) from one wolf collar to determine the feasibility of determining summer predation patterns from GPS locations. Potential kill sites were identified from GPS clusters having = 2 points that were = 200 m apart. Of the 25 GPS clusters sites investigated, we found evidence of a large mammal predation event at 40% of the sites. The probability of a large mammal predation event being present at a GPS cluster site increased with the number of days a wolf spent at the cluster (P = 0.024) and decreased if the cluster had been revisited over a number of non-consecutive days (P = 0.018). Developing techniques that link GPS collar technology and animal behaviour could be important to increase our understanding of complex systems for the benefit of conservation and management efforts.
