A comparison of activity patterns for captive Propithecus tattersalli and Propithecus coquereli

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.
