Rhythms and Time Allocation for Diurnal Activities of Captive Sichuan Snub-nosed Monkeys
Understanding the diurnal activities patterns of captive Sichuan golden snub-nosed monkeys(Rhinopithecus roxellana)can provide basis for improving breeding management measures and animal welfare.From January 2022 to De-cember 2022,rhythms and time allocation for diurnal activities of nine Sichuan golden snub-nosed monkeys at the Hang-zhou Zoo were studied using an instantaneous sampling method.The results showed that the monkeys had two feeding peaks,09:00-11:00 and 15:00-16:00.Resting occupied the majority of the daytime activities(40.81%),followed by feeding(20.49%),movement(17.09%),grooming(11.04%),cuddle-sitting(5.60%),playing(3.41%)and other be-haviors(1.56%).There was seasonal variation in the time allocation of diurnal activities with feeding,allogrooming and cuddle-sitting being less common in summer while resting being more common in summer.Allogrooming and cuddle-sitting were significantly higher in winter than in other seasons(p<0.05).There were also differences in time allocation among dif-ferent age-sex groups,with juvenile monkeys exhibiting more feeding and playing behavior and less resting,adult males ex-hibiting more movement and less autogrooming,and adult females exhibiting more autogrooming and allogrooming(p<0.05).External interference(tourists)under the glass partition did not have a significant effect on their behaviors(p>0.05).
