摘要
I studied a group of woolly monkeys (Lagothrix lagotricha) for 1800 hr from early 1985 until September 1987 near the lower Apaporis river of the Vaupes Department in the eastern Colombian Amazon. The group had an activity budget of 29.9% rest, 38.8% move, 25.8% forage, and 5.5% other activities during 720 hr of observations evenly spaced throughout this year The only significant change in these activities during the study period was social activity, which increased as a function of increased food supply. Average diurnal activities of resting and moving are negatively correlated, and each activity show significant changes during the day, while foraging show no significant change. The activity budgets of the adult males and females are not significantly different but the activities of the juveniles and infants showed much more social activity than the adults. High moving scores may be correlated with the comparative infertility of the soils of the Caparu forest, which require increased effort to maintain the energy levels necessary for maintenance and reproduction in Lagothrix.
