Abstract: Data on activity budgets,activity heights,and semi-positional behaviors were collected from one provisioned group of Rhesus macaques (Macaca mulatta )between November 2005 and October 2006 at Seven-star Park,Guilin, Guangxi Province,using an instantaneous scan sampling method. We compared the activity budgets,activity heights,and positional behaviors by sex-age or age classes. Our results indicated that the Rhesus macaque at Seven-star Park was a semiterrestrial species,and spent much time resting (41. 5% );sitting was the most frequently adopted resting (85.5% ) and feeding (85. 4% )posture. Quadrupedal walking was the most prevalent locomotor mode (64. 5% ). There were sex differences in activity budgets of adult individuals:adult females spent more time grooming than did adult males. They also differed among age classes:resting time tended to increase with age,whereas playing time decreased. There were also significant variations in activity height and locomotor mode for different age classes. Adults were more terrestrial than were other classes. They also walked quadrupedally more frequently than the other ages. Subadults leaped more frequently than did individuals of other ages. Juveniles climbed and bridged more frequently than did adults. These variations may be related to the differences in body sizes and activity levels of different ages,as well as to the discontinuous tree canopies. Our
results will contribute to understanding the behavioral adaptation of different sex-age classes in rhesus macaques to their social and natural environment
