Discovering and learning tool-use for fishing honey by captive chimpanzees

Wild chimpanzees commonly use sticks to fish for termites, ants or honey. This ability seems to be socially transmitted to juveniles by their mothers across generations. In a natural environment, the limited visibility of this behavior with regards to the...

Environmental enrichment by varied feeding strategies for individually caged young chimpanzees

Providing an ear of unhusked corn daily or on alternate days, in addition to laboratory chow, resulted in more time spent contacting food [primarily the corn] an hour after feeding [34% & 55%] than feeding laboratory chow alone [8% &...

A theoretical approach to environmental enrichment from the perspective of occupational therapy

By providing chimps with occupational opportunities, we empower them to act and to exert control over themselves and their environment.

Living naturally: Aspects of wild environments relevant to captive chimpanzee management

Discussion of activity budgets of chimpanzees living in their natural habitat. The animals spend about 50% of the time feeding, 15% of the time resting, less than 15% of the time grooming each other.

Quantitatively tested environmental enrichment options for singly-caged nonhuman primates: A review

Compatible companionship has a therapeutic effect on behavioral disorders, providing long- term stimulation of a great variety of species-typical social behavior patterns. Inanimate objects have little impact on behavioral disorders, but some of them provide appropriate means for the expression...

Long-term use of 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.

The disappearing ice cube

Ice cubes are distributed across the floor, hidden in high plastic barrels (we call these igloos), tucked into corners of the cages, etc. As the animals come out, the excitement of the hunt starts and continues until the last ice...
