the be hav ior and distribution of new and possibly “naive” prey (Berger, Swenson, and
Persson 2001), and become adept at capturing these prey as the population is man-
aged to an equilibrium where sufficient prey are available to support the needs of those
predators. Predators start with familiar prey and those that are easy to capture, learn
how to capture prey that represent a relatively low risk of injury or death, and fi nally
opportunistically capture more risky prey species, using behavioral cues linked to prob-
ability of success.

Food habits changed based on ease of capture and knowledge of new prey,
progressing from porcupine and mule deer in the 1990s to opportunistic
captures of high- risk species including elk after 2010.
