Effects of novelty and familiarity on illness-induced aversions to food and place cues in coyotes (Canis latrans).
Two experiments investigated the effects of novelty and familiarity on illness-induced aversions to taste and place cues in coyotes (Canis latrans). Coyotes were made ill on familiar food laced with lithium chloride in a novel place and then received preference tests. In Experiment 1, coyotes avoided the previously poisoned familiar food in the novel treatment place but readily ate the same familiar food in a familiar safe place. In Experiment 2, the results of Experiment 1 were replicated, and it was found that coyotes would eat a different familiar food in the novel treatment place. On the basis of the results of this and other studies, a model for averting animals from places where they are not wanted is presented.
