A study of the postures and locomotor modes of Alouatta palliata was conducted from mid-June to mid-September 1974 on Barro Colorado Island, Panama Canal Zone. Activities, postures, and locomotor modes were recorded relative to the position of the animals in the trees and to the size and angulatiry of the support structures. Most activities, in particular feeding, occurred on small, flexible, nearly horizontal supports on the periphery of tree crowns. Differential use of the various zones of the tree crowns and support size classes were noted among several age-sex categories.
