Red-capped mangabeys are endangered primates native to the jungles of Nigeria. They have distinctive markings around their eyes and a variety of vocalizations for communicating with other troop members. Two females live at Binder Park Zoo, Lola and Kanzu. Lola and Kanzu enjoy training sessions with keeper staff. They are trained to present their hands and feet on cue, stand or climb up the mesh, and staff is working with them on injection training. All training is done by operant conditioning where the animal can choose to participate or not. Training is done for medical purposes to help us evaluate their health in a stress-free environment. Their favorite reward for training is fruit.
Wild mangabeys spend much of their day foraging for food. Lola and Kanzu can be seen foraging in the leaves and grass for insects or food placed there by zookeeper staff - enrichment that promotes natural behaviors and keeps their minds stimulated. One of their favorite enrichment items are puzzle feeders that they must manipulate to receive the food contained within.
