The fun factor in the Zoo's Lost Forest increased 15-fold with the arrival of tufted capuchin monkeys in 2011. These highly intelligent little primates are certainly keeping things lively! They came to us after participating in facial recognition and intelligence tests at Yerkes National Primate Research Center. Each monkey has his or her own distinct personality. Lulu, for example, is timid but can also be quite stubborn. Lance is very people oriented, and Ozzie is clearly the dominant male. Their entertaining "monkey business" keeps Zoo visitors swinging by for more!
