Abstract I studied the positional behavior and habitat use of Cercopithecus petaurista, the lesser spot-nosed monkey, in the Ivory Coast's Taï Forest for 15 months. I compare these data with similar information collected on sympatric groups of Cercopithecus diana and C. campbelli in order to examine further the relationships between locomotion, posture, support use, stratal use, body size, diet, activity patterns and foraging behavior. Spot-nosed monkeys are predominantly quadrupedal primates that frequent the top layer of the understory during all maintenance activities. Locomotion is characteristically slow and cautious; travel takes place on branches and boughs while foraging occurs on twigs and branches. Postural behavior of Cercopithecus petaurista reflects their reliance on more ubiquitously distributed, less mobile food items. The relationship between body size, climbing, leaping and support use among Taï guenons is weak; interspecific differences are more likely functions of strata use and overall behavioral characteristics, e.g. crypticity. I also compare the locomotion and support use of Cercopithecus petaurista with that of C. ascanius from Uganda's Kibale Forest (Gebo and Chapman, 1995a) in order to assess the behavioral similarity of members of the same superspecies. Although overall support use is quite similar, the monkeys differ significantly in frequencies of quadrupedism, leaping and climbing. I present possible reasons for and implications of these differences.
