The activity patterns and social interactions of two species of captive sifaka were observed during a 2-year period. Allogrooming was not observed in golden-crowned sifaka and they spent significantly more time resting than the Coquerel's sifaka. Females of both species were found to be dominant to males. The golden-crowned sifaka (Propithecus tattersalli) spent significantly less time feeding than the Coquerel's sifaka. Temperature, time of day, species, and interpair comparisons for the golden-crowned sifaka were found to affect activity and social interactions, while gender did not. Like the Coquerel's sifaka, the golden-crowned sifaka was found to be diurnal; however, they differed in that the golden-crowned sifaka did not descend to the ground.
在两年的时间里，对两种圈养的狐猴的活动模式和社交互动进行了观察。在金冠狐猴中未观察到相互梳理毛发的行为，并且它们休息的时间比柯氏狐猴显著更多。发现两个物种的雌性都比雄性占主导地位。金冠狐猴（Propithecus tattersalli）进食的时间比柯氏狐猴显著更少。发现温度、一天中的时间、物种以及金冠狐猴的配对间比较会影响活动和社交互动，而性别则不会。与柯氏狐猴一样，金冠狐猴是昼行性的；然而，它们的不同之处在于金冠狐猴不会下到地面。
