A grass foraging device for captive chimpanzees (Pan troglodytes)

In the wild, chimpanzees spend most of their time foraging, so any device that stimulates this behaviour in captivity could potentially be effective enrichment. A simple grass foraging device constructed of a polyvinyl chloride (PVC) pipe cut in half lengthwise...

Removal of a trauma-inflicting alpha matriline from a group of rhesus macaques to control severe wounding

Results identify an unusual outbreak of serious wounding by the alpha matriline of a large captive group [of rhesus macaques] and indicate that identification and removal of the animals responsible can be an effective management procedure for controlling such injuries.

Rate of habituation to an enrichment device by rhesus macaques with lesions of the entorthinal cortex, hippocampal formation, or parahippocampal gyrus

Significant differences were found in the rate of habituation [to a rubber ball serving as enrichment] between animals with entorhinal or hippocampal lesions and normal control animals. This study addresses the special needs of monkeys with experimental cortical lesions and...

Caged stumptailed macaques voluntarily work for ordinary food

Ninety-nine of the biscuits were placed in a freely accessible dish attached to the mesh of the front of the cage. Thirty-three biscuits were offered in a food puzzle. Twenty-five percent (4/16) of the subjects ignored the food puzzle during...

Use of different foraging substrates in captive Cebus capucinus

In order to promote initial interest in the [four different] litters [presented in different quarters of the enclosure] each day, 140 g of raisins were spread across the top of each litter immediately before each observation session. ...The ground corn...

Enrichment for woolly monkeys

A pumpkin with the top cut off and several slits cut down the side provides hours of activity and seeds to eat. The first time the [group-housed] woolies saw a pumpkin or a sunflower head, they were frightened but quickly...
