Evaluation of a chimpanzee enrichment enclosure

A large, three-part playground for captive chimpanzees was constructed and evaluated in terms of area use and behavior changes. Comparative behavioral samples were obtained on 38 subjects in the existing indoor-outdoor run and in the enclosure. The chimpanzees used the...

Reciprocity and interchange of grooming and ?support? in captive chimpanzees

Reciprocity and interchange of grooming and coalition formation of captive chimpanzees, Pan troglodytes, were studied at a group level as (partial) correlations between an actor matrix and a receiver matrix. Periods in which one male clearly occupied the alpha-position and...

Chimpanzees (Pan troglodytes): Problem seeking versus the bird-in-hand, least-effort strategy

Chimpanzees will sometimes attempt to solve a discrimination problem for food rather than simply taking freely accessible food.

Effect of increased space on behaviors of captive chimpanzees

The results suggest that increased space may reduce some social interactions. It is not clear if levels of social activity [in general] in smaller spaces are 'abnormally' high, and are reduced to more 'normal' levels following an increase in available...
