The nuts and bolts of captive chimpanzee diets and food as enrichment: A survey

Results suggest facilities are moving away from timed feeding schedules, which tend to increase prefeeding levels of agonism, to feeding a wide variety of food throughout the day and using a wide variety of feeding techniques.

Variables influencing the origins of diverse abnormal behaviors in a large sample of captive chimpanzees (Pan troglodytes)

Rocking and self-sucking were significantly more likely in hand-reared animals. Coprophagy and depilation of self were significantly more likely in mother-reared animals. ... The only significant sex difference was a higher prevalence of coprophagy in females and a higher prevalence...

Allowing captive marmosets to choose the size and position of their nest box

Preferences for nest box size and position were tested in two groups of common marmoset,Callithrix jacchus jacchus.In a pre-test phase two, new, wooden nest boxes were introduced to each group alongside their old metal one, so that the animals could...

Friendship’ for fitness in chimpanzees? Animal Behaviour 58, 1223-1229

It has been repeatedly suggested that primates trade social services for fitness benefits in their relationships with the opposite sex. We tested this proposal in a colony of captive chimpanzees,Pan troglodytes, by examining behavioural data on grooming, agonistic support and...

Assessing the value of television as environmental enrichment for individually housed rhesus monkeys: A behavioral economic approach

The goal of this study was to evaluate television as a source of environmental enrichment for individually housed rhesus monkeys (Macaca mulatta) by using the concepts of behavioral economics. Phase I entailed the use of operant conditioning to assess the...

Changes in nearest-neighbor association in a captive group of Western Lowland gorillas after the introduction of five hand-reared infants

The integration of five hand-reared infants into a group of 5 females and 1 male was successful and without incident. Findings lend strong support to the importance of peer groups and the presence of a silverback male for facilitating the...
