Summary
Great apes in zoos exhibit different behaviors in exhibit versus holding areas. Understanding these species-specific reactions in all enclosures is crucial for assessing great ape welfare and behavior needs.
Area of Science:
- Primate behavior and welfare
- Zoo animal management
- Comparative ethology
Background:
- Zoos frequently move primates between exhibit and holding areas for management.
- Exhibit design must balance animal husbandry with naturalistic enrichment.
- Current welfare assessments often overlook off-exhibit holding areas.
Purpose of the Study:
- To investigate species-specific behavioral responses of chimpanzees and gorillas to holding areas.
- To compare behavior patterns between exhibit and holding environments.
- To highlight the importance of including all enclosure types in welfare assessments.
Main Methods:
- Zoo-living chimpanzees and gorillas were observed during daily transfers to off-exhibit holding areas.
- Behavioral data were collected to identify species-specific reactions.
- Feeding-foraging behavior was compared between exhibit and holding areas.
Main Results:
- Chimpanzees showed increased aggression and self-directed behaviors in holding areas.
- Gorillas exhibited increased activity and prosocial behaviors in holding areas.
- Both species engaged in more feeding-foraging behavior within exhibit enclosures.
Conclusions:
- Holding areas may not fully meet the behavioral needs of captive great apes.
- Comprehensive welfare assessments must consider all components of an animal's environment.
- Species-specific behavioral differences necessitate tailored management and enclosure design.
