Prey selection is exhibited by predator populations that kill a prey species disproportionate to its availability, or alternatively, individual predators that select prey disproportionate to the mean selection exhibited by their populations. Prey selection is a simple calculation when one can determine prey availability; however, measuring prey availability is challenging. (L. Mark Elbroch, Patrick E. Lendrum, Hugh Robinson, and Howard B. Quigley. 2016. Population- and individual-level prey selection by a solitary predator as determined with two estimates of prey availability. Canadian Journal of Zoology. 94(4): 275-282. https://doi.org/10.1139/cjz-2015-0092)
