A review. Regurgitation and reingestion is a common phenomenon in captive lowland gorillas, but it has never been reported in wild populations. Although changes in diet have been shown to reduce the behavior, little is known about the underlying mechanisms that lead to its development and maintenance. A comparative analysis of ruminatory behavior in humans and stereotypic behavior in captive, domesticated animals was carried out which revealed several nutritional and motivational factors that may contribute to the sustained performance of this behavior in captive gorillas.
