Restraint methods of laboratory non-human primates: A critical review

Published information provides scientific evidence that traditional, involuntary restraint techniques of research non-human primates are intrinsically a source of distress resulting from fear. It has been documented that common methods of enforced restraint result in significantly increased adrenal activity as...

A hammock in the rain forest for chimpanzees

Getting the [group-housed] chimps off harsh concrete surfaces and providing them with softer substrates has long been a goal. The hammock has been up for three months now. It gets constant abuse and absorbs it well. Some chimps use the...

Chimp platforms in outdoor enclosure

A project was initiated to take advantage of the vertical space by building a wooden platform with two decks in each of the eight corrals. The platforms have been used by chimpanzees of all ages, and have been the center...

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.
