Batesian mimicry has been used by prey to avoid predation but in some cases predators have learned to associate visual cues with palatability. The purpose of this research is to study if over time squirrels can learn to associate color with unpalatability. The physical characteristics of the food will provide a visual cue in which the squirrels can learn to determine palatability. Squirrels were trained with fully palatable food, then given three variations of palatability each of different colors with different amounts of apple cider vinegar. With a chi-squared result of 2.34 we concluded to reject our null hypothesis. The results showed that over the course of a week the squirrels were able to use visual color cues to determine palatability.
