Novelty influences use of play structures by a group of socially housed bonnet macaques (Macaca radiata)

It is important to note, however, that all structures (milk crate swings, fire hose suspended from two points, PVC tube suspended from two points, toys, rope dangling by one end) showed a decline in use over the testing period in...

Response to temporally distributed feeding schedules in a group of bonnet macaques (Macaca radiata)

Portioning the daily food ration in four rather than two different feedings resulted in a significant increase in the amount of time spent foraging and eating/drinking in group-housed animals.

Utilization of a sensory diet approach for enrichment and mitigation of abnormal behaviors in captive chimpanzees (Pan troglodytes)

Treatment consisted of stimulation of the tactile senses through use of various paper media, a combing/brushing schedule and muscle pressure techniques. A reduction in the rate of coprophagive events was observed.

Effect of environmental enrichment devices on behaviors of single- and group-housed squirrel monkeys (Saimiri sciureus)

This would suggest that enrichment provided by social interaction ... may play a greater role in maintaining the monkeys' psychological well-being than did physical enrichment devices.

Better living through training

This paper will view the training program from the perspective of a keeper joining the team after the program was solidly in place. It will explore the ways in which training allows apes and their keepers to cooperate to make...

Orangutan Species Survival Plan Husbandry Manual: Behavioral Biology

Abnormal behaviors occurring in some captive orangutans include lack of maternal skills, stereotypic behaviors, atypical sexual behavior and hyper-aggressiveness. Changes in social groupings, improved housing, behavioral enrichment and positive reinforcement training are known to alleviate some of these undesirable behaviors.

A change in housing condition leads to relatively long-term changes in cell-mediated immune responses in adult rhesus macaques

Changes in the social environment, such as removal and/or reintroduction of groupmates, affect theimmunological responses of captive macaques of all ages. This study compares cell-mediated immuneresponses of adult Macaca mulatta (N= 17) whose housing condition was changed from social to...

Catering to caterrhines: Food enrichment at the University of Washington’s Regional Primate Research Center

As simple and relatively inexpensive form of enrichment each animal received a treat (e.g., fruit, vegetable, exposure to foraging device) on 4 days per week. This costs about $0.50 per macaque or baboon per week.

Outdoor access: The behavioral benefits to chimpanzees

When compared to the results of ameliorative environmental enrichment techniques furnished to the indoor-housed subjects, the small outdoor groups of [two or three] chimpanzees showed broader and more dramatic improvements in well-being. Animals with outdoor access showed significantly less abnormal...
