A Multi-Pronged Approach to Studying Human-Animal Interactions in Zoo Settings

Zoos of the past focused primarily on animal exhibition, yet the modern zoo has shifted to a focus on animal conservation and public education. This change has coincided with a negative shift in public opinion towards zoos after documentaries such as Blackfish, leading to comparatively more positive views of sanctuaries. These preferences seem to be influenced by the lack of animal exhibition at sanctuaries, suggesting that human influences on animals are important to public perceptions of zoos. Thus, human-animal interaction research is essential to understanding perceptions of zoos and human influences on captive animals. This dissertation addresses both factors. Study 1 assessed public opinions on zoos versus sanctuaries, and investigated how these opinions are impacted by knowledge of zoo practices. Highlighting any positive information, but particularly in relation to conservation, led to more positive public opinions. Studies 2 and 3 considered human-animal interactions through human impacts on captive animals, as further knowledge could both increase animal welfare, and then, positively influence public opinion. Study 2 examined the influence of visitors on the behaviors of zoo-housed parrots in an aviary. Birds engaged in decreased positive behaviors, increased negative behaviors, and more birds were present as visitor numbers increased. The increase in negative behaviors was minimal compared to the increase in birds present, which may indicate the birds were not negatively impacted by visitors. Study 3 evaluated the judgment biases of two ambassador animals after exposure to zoo visitors. The chicken displayed pessimism whether it was held or perched, but the tegu displayed pessimism only when no visitor touch occurred. This suggests negative effects of visitor interactions for the chicken, but touch interactions may not be aversive to the tegu. All three studies contribute to our understanding of human-animal interactions for the improvement of animal welfare and public perceptions of these facilities.
