Abstract: | The activities and feeding behavior of pregnant baboons, Papio cynocephalus,were studied in two free-ranging groups in Amboseli National Park, Kenya. Both the environmental conditions and the age of
their fetuses influenced females’ activity budgets and feeding behavior. Females fed more and rested less during the dry season
than during the wet season, and most females spent progressively more time feeding and less time grooming than expected (based
upon the amount of recent rainfall) as their fetuses matured. During the wet season, females also devoted significantly greater
proportions of feeding time to consumption of grass blades, leaves, and flowers and significantly smaller proportions of their
feeding time to feeding upon seeds, corms, and fruit. As their fetuses became older, the proportion of time spent feeding
upon seeds increased, and the proportion of time spent feeding upon grass blades and fruit declined. |
