An Evaluation of Conditioned Taste Aversion to Deter Nest Predators: A Non-lethal Approach
Traditionally, reducing game-bird nest depredation has involved lethal means of predator control. We evaluated a non-lethal alternative, conditioned taste aversion (CTA), in Tom Green County, Texas. Simulated nests were constructed and baited with 3 eggs injected with lithium chloride, an aversive chemical. Simulated nests were constructed along the perimeter of a 40-ha pasture. A 21-day treatment phase was conducted with depredated nests being rebaited daily with treated eggs. A 28-day posttreatment phase involved establishing 24 non-treated nests in both the treated pasture and a control...
