In the context of foraging, many animal species produce specific calls that attract others. Researchers hypothesize that these vocalizations function to inform others about food; however, few studies have investigated whether food-associated calls alone are sufficient to cause individuals to respond as if they have been informed about food. Playback experiments on white-faced capuchins (Cebus capucinus) investigated whether listeners could infer the presence of food merely by hearing food-associated calls. Recipients looked significantly longer toward the call source and approached the speaker more often after hearing food-associated calls, as compared with control calls. Because these responses are not indicative of feeding, it is unclear whether listeners associated the calls with food. Nonetheless, these responses, specific to food-associated calls, may increase individuals' chances of finding food.
