Increasing foraging opportunities for a group of captive capuchin monkeys (Cebus capucinus).
Capuchin monkeys often employ complex manipulative skills while recovering food items. Five captive Cebus capucinus were presented with two identical feeders that required the monkeys to lift up flaps, search through hay, and perform coordinated hand movements in order to obtain food items. The intent of this study was not to merely increase the amount of time the animals spent feeding, but to provide opportunities for greater expression of species-typical foraging behavior. In addition to their regular diet, figs and various types of unshelled nuts were placed inside the feeders. The monkeys avidly searched for and removed food from the feeders, displaying a wide variety of manipulative abilities. The amount of time the animals spent foraging significantly increased (p less than 0.05) whereas the amount of time the animals spent locomoting and resting significantly decreased (p less than 0.05) when the feeders were available. The feeders were portable, durable, easy to clean, and relatively inexpensive.
