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.
