The presence of visual barriers decreases antagonism in group housed pigtail macaques (Macaca nemestrina)

Instances of bite, grab and chase were found to be significantly greater [among members of harem groups of 23 pig-tailed macaques] when visual barriers were absent compared to when they were present.

Risk factors for self-injurious behavior in captive rhesus monkeys (Macaca mulatta)

Research has shown that approximately 10% of captive, individually housed monkeys have had some veterinary record of self-injurious behavior within their life-time. The incidence of self-biting was 14% [!] in a test colony of 188 male individually housed rhesus macaques....

Vertical poles with cow bells: An enrichment device for chimpanzees (Pan troglodytes)

Adding a simple cow bell can increase use of vertical climbing poles and may have resulted in increased locomotor activity for [group-housed] captive chimpanzees. These data were collected in 1996/97 and the cow bells are still 'ringing' two years later.
