Species-specific behaviors (2007)

Jensvold, M. L.

Abstract

The relationships between captive non-human primates and their caregivers are critical to animals welfare. One method to mitigate the potential negative effects and to promote positive relationships is for caregivers to employ species-specific behaviors in their interaction with their charges. During Chimpanzee Behavior Condition (CBC) data collection, a caregiver used chimpanzee behaviors and vocalizations while interacting with the animals. In Human Behavior Condition (HBC) data collection sessions, a caregiver presented human behaviors and used speech instead. the interactions included grooming, playing, serving meals, presenting enrichment or simply observing the chimpanzees. The chimpanzees engaged in more play and grooming in CBC than in HBC, in which they were less interactive. The chimpanzee behavioral training included many play behaviors, including play faces and chimpanzee laughter, as well as grooming and submissive behaviors. We have found that the submissive behaviors reduce inter-group aggression. Thus, the use of species-specific behaviors can also improve relationships within the captive group.
