The use of positive reinforcement techniques with chimpanzees for enhanced care and welfare

Training is teaching. Teaching in a positive reinforcement-based system relies on gaining the voluntary cooperation of the chimpanzees during procedures, such as injection, blood collection, auscultation or urine sampling, or husbandry-related situations such as cooperative feeding. Several positive reinforcement training...

Control over videotape enrichment for socially housed chimpanzees: Subsequent challenge tests

The lower expression of stress-related behaviors by chimpanzees that took advantage of the opportunity to control the videotape apparatus implies that exerting control over the environment may have a generalized effect by lessening disturbance caused by mildly challenging situations.

Effect of enclosure size and complexity on the behaviors of captive chimpanzees (Pan troglodytes)

Changes in behavior of 5 adult chimpanzees that coincided with transfer to a larger, complex environment are described. The percentage of time spent traveling nearly doubled in the larger enclosure. The animals used all structures and all areas in the...

Mr. Sockies for Chimpanzees

The Primate Foundation of Arizona (PFA) makes Mr. Sockies for chimpanzees. They consist of a food treat (popcorn, pretzel, crackers, etc...) knotted inside a sock or small piece of fabric (10' or less). The legs of old jeans work well....

Exhibit use by great apes as part of a post-occupancy evaluation

All apes [6 chimpanzees and 15 gorillas] used the various strata of the exhibits, but there were species differences in exhibit use. Four of the six chimps spent most of their time in the highest two meters of the exhibit,...

The impossible housing and handling conditions of monkeys in research laboratories

The prevailing housing and handling conditions of monkeys in research institutions is described. The present situation in primate research laboratories strongly suggests that professional judgment is no guarantee that the inhumane housing and handling conditions of laboratory monkeys will ever...

Primate innovation: Sex, age and social rank differences

Analysis of an exhaustive survey of primate behavior collated from the published literature revealed significant variation in rates of innovation among individuals of different sex, age and social rank. We searched approximately 1,000 articles in four primatology journals, together with...

What does a chimpanzee need? Using natural behavior to guide the care and management of captive populations

Their tendency toward natural behavior is probably little changed from their wild counterparts, despite the overwhelming influence of captivity on behavior... From a chimpanzee's point of view, it would be better to stimulate behavior characteristics of the natural environment of...

Using positive reinforcement training techniques to facilitate the assessment of parasites in captive chimpanzees

The chimpanzees in our colony have been trained, using positive reinforcement techniques, to perform a variety of husbandry, management, and research behaviors, including presentation of their posteriors. Therefore, it was relatively easy to train the subjects to voluntarily present the...
