【Abstract】 Between September 2005 and July 2006,we studied the behavioral development of three Sichuan snub-nosed monkeys Rhinopithecus roxellana at Jinan zoological Park.We collected data using the all-occurrences recording technique and instant and scan sampling methods.The results showed that infants first ventured away from their mother at 6 days of age,stood up at 13 days of age,and engaged in exploratory play at 29 days of age.In 2 months,the infants could be found in physical contact with their mothers.They could be located either on iron nets or on the ground or on the poles after 3 months.更多还原
