Predation risk in relation to brain size in alternative prey of pygmy owls varies depending on the abundance of main prey

PLoS ONE, 2020
Large brains in prey may select for adoption of anti-predator behavior that facilitates escape. Prey species with relatively large brains have been shown to be less likely to fall prey to predators.
