Basic research into the mechanisms of food aversion learning both among captive vertebrates and in the field setting. Primary focus has been on the influence of cholinergic agonists upon the foraging of free-ranging avian predators and other substances on the foraging of mammalian predators. This work has produced interesting results concerning the possible influence of illness-based food aversions upon the evolution of prey toxicity and mimicry. The work also has important implications concerning non-lethal methods that control predation upon endangered species.
