Nighttime plays an important role in the lives of captive primates. There have been several studies in primate research that have focused on group composition and nighttime activity levels in humans, macaques, and baboons, but very little is known about the nighttime behaviors of captive chimpanzees. This study used a remote video recording system to record the nighttime behaviors of five captive chimpanzees (Pan troglodytes). The resulting data were analyzed and classified using an observational data taxonomy of chimpanzee behavior to provide a nighttime behavioral profile for each chimpanzee and the chimpanzees as a group, including the percent of time each chimpanzee spent in each behavior context, as well as other variables such as blanket use, proximity to other chimpanzees, and movements while inactive. These data may be used as a tool for comparison between the nighttime activities of humans, chimpanzees, and other nonhuman primates. They may also provide a basis for determining more optimal nighttime environments for captive chimpanzees.
