a A sixteen-day movement from March 7, 2013 – March 23, 2013 of an adult male cougar (AS07) used to illustrate patterns in speed, turning, straightness, and site fidelity with GPS points and paths color-coded from red to orange to yellow to green and then to blue through time. Insets of movements around known prey (mule deer) cache sites denoted by white stars demonstrate that it is common for cougars to intermittently feed on prey items, leave the cache site for periods of time, and return at a later time. b Graphs of speed from net displacement and c degree of turning alone demonstrate they are not always effective indicators of feeding behavior because associated measures of velocities can be both small and large and turning angle also can be highly variable, while the d straightness index captures the short bouts of leaving and returning to caches. e The site fidelity index captures when cougars are feeding at cache sites
