Chimpanzees in single cages and small social groups: Effects of housing on behavior

Chimpanzees housed in pairs or trios showed fewer signs of tension, anxiety and aggressiveness than those housed singly. However, providing one or two social companions did not appear to ameliorate abnormal behavior over the long term.

The neighbor effect: Other groups influence intragroup agonistic behavior in captive chimpanzees

Hearing the vocalizations of neighboring groups increased the likelihood of intragroup fighting. It may be indicated to construct corrals at a distance from each other to avoid this undesirable neighbor effect.

An analysis of regurgitation and reingestion in captive chimpanzee

This study assesses R/R [regurgitation/reingestion] in 13 indoor-housed chimpanzees living in pairs and trios. ... Social disturbance did not elicit this behavior. Statistical tests showed no relationship between individual differences in R/R rates and rates of other abnormal behavior classes,...

Chimps take over an abandoned logging camp: Integrated behavioral enrichment at the Los Angeles Zoo

The chimps can insert sticks [into the logs] to push the food items along the inside of the log to a point where they can reach it. The public can watch the action and admire the chimps' dexterity.

Long-term use of television, balls, and mirrors as enrichment for paired and singly caged chimpanzees*

Chimpanzees used televisions, balls, and mirrors for 0.27-1.53% of the observation time after several years of exposure to the enrichment items. Television and ball use were significantly higher than mirror use. *Abstract of this work has been published in: American...

Managing aggression in multi-male, multi-female chimpanzee groups

We found that wounding aggression was minimal during introductions of females to males or other females, and during male-male introductions of formerly single-caged adolescent and young adult males having long-term prior visual familiarity. Serious wounding occurred during male-male introductions, particularly...
