Abstract

Enrichment plays a key role in the psychological well-being of captive non-human primates (Buchanan-Smith, 2011). Institutions that house captive apes are required to provide individuals with enrichment items. However, many institutions do not provide enrichment during the evening hours, when it is presumed apes are sleeping. Though captive chimpanzees rest between 8 to 12 hours each night this is not a continuous, unencumbered slumber (Videan, 2005). The aim of this study was to determine if enrichment items, such as blankets, toys, magazines, and containers, were being used by the 3 chimpanzee residing at the Chimpanzee Human Communication Institute. During the summer of 2012, the chimpanzees were recorded during evening hours. Using 80 hours of data, the chimpanzees used variety of enrichment items. They used blankets significantly more (p<.05) than other items. These data provide preferred types of enrichment items for primates housed in similar captive situations.
