     Study of the nocturnal owl monkey (Aotus spp.) has been limited in nature; in captivity owl monkeys have been used predominantly in biomedical research, as well as some recent behavioral studies. As owl monkeys occupy a unique temporal niche and other marked differences from other platyrrhines, it would be beneficial to have a better understanding of their positional behavior and locomotion for the purposes of captive management. At the DuMond Conservancy there is a captive colony of Aotus nancymaae housed in semi-naturalistic environments which provide both natural perching and PVC perches simulating the spring of living branches and encouraging natural locomotor behavior. Twelve individuals of ages 7-11 were selected as representatives for natural locomotor behavior in adult Aotus for this study. Preliminary results indicate high rates of leaping 15 per hour(±4.197). Leaps observed were divided into four types: horizontal, vertical, bounding, and vertical-cling and leaps. High rates of clinging and suspensory locomotion were also observed, approximating 22 times (±11.188) and 4 times (±2.512) per hour respectively. Instantaneous sampling is being utilized in order to obtain an accurate and random data set of Aotus positional behavior. Cages have been modified with additional vertical substrates of natural materials. This study aims to bring to light the special considerations that should be taken in order to ensure best designed enclosures to allow species typical behaviors in captivity.
