Abstract: To understand behavioral rhythms of captive Chrysolophus amherstiae in summer and autumn, we monitored the behavior of six captive individuals in Hunan Wild Animal Rescue and Breeding Center in June, September, and October, 2016 by instantaneous scanning. We analyzed behavioral time allocation in summer and autumn. Based on their functions, sixteen types of behavior observed were classified into five categories, including exercise, resting, feeding, cleanup, and alert, with exercise being most frequently occurred. In summer, fluctuation of resting was the most tremendous, while proportion of exercise was the highest in most time periods. Compared with summer, the tendencies of five categories in autumn were smooth and distinct; however, exercise was also the most frequent and resting showed the most fluctuations. Alert was less prominent, with low proportion. The results in this study were similar to that of previous studies on time allocation in their reproductive cycles of C. amherstiae. Exercise and resting were the two kinds of behavior with the highest frequency for captive C. amherstiae. The difference between our finding and previous ones was that the proportion of cleanup increased obviously in this study.
