Activity patterns of captive and free-ranging long-tailed macaques (Macaca fascicularis) (1993)

Leon, S., Taylor, L.

Abstract

In summary, the wild and captive macaques exhibited significant differences in four of the six activity categories we examined. There was no significant difference in the amount of grooming between the two populations counter to our expectations. Overall, the activity to rest ratios show that the captive animals were active only half as often as their wild counterparts in comparison to the amount of time each spent resting. Our hypothesis that the monkeys would feed and forage less in captivity than they did in the wild was supported by the data.
