Abstract:I examined sex differences in the ranging patterns of 3 female and 3 male wild spider monkeys. Each of the focal males used the home range widely, whereas each of the focal females used a distinct, restricted area of the home range. The males traveled longer distances than the females did. Although males were consistently in larger parties than females were, travel speed was affected by party composition rather than party size. All-male parties traveled faster than other party types did. Foraging manner also differed between sexes. Males spent more time feeding on fruits and less time on flowers and traveled longer distances between feeding trees. Both males and females used salados, where they ate soil and drank water. Salado location is likely to have affected the ranging pattern. Males used boundary areas more frequently than females did, often traveling along the boundary area in alliance with other males. Males also used areas that had been part of neighboring groups’ home ranges and were not used at all by females of the group. Greater travel distance of males is likely to be facilitated by consumption of a higher caloric diet. I compare the social structure of spider monkeys with that of chimpanzees, whose society is characterized by male-philopatry and female dispersion.
