We measured the amount of time that 20 rhesus monkeys,Macaca mulatta, (four adult males, 10 adult females, four juvenile males, and two juvenile females) contained in two enclosed social groups devoted to 16 activities. For 14 of these 16 behaviors we found significant differences between age-sex classes. For 14 behaviors, there were also differences between individual monkeys. Twelve of the 16 activities showed significant diurnal variations. We discuss the relation between the use of time and social position, the adaptive significance of diurnal variation, and compare our data with that available for free ranging rhesus.
