ItemThe effects of zoo visitors on Quokka (Setonix brachyurus) avoidance behavior in a walk-through exhibit(WILEY, 2018-07-10)The behavior of zoo animals may be influenced by visitors, with possible implications on animal welfare. We examined the effects of the presence of visitors on the presence and visibility of free-ranging quokkas (Setonix brachyurus) in preferred areas of a walk-through enclosure at Melbourne Zoo, Australia. In a controlled experiment, two visitor treatments were randomly imposed: (1) enclosure open to visitors as normal ("Open") and (2) enclosure closed to visitors ("Closed"). Treatments were imposed for 2-day periods, with five replicates of each treatment (10 2-day periods in total). Instantaneous point sampling of camera footage at 1-min intervals from 09:00 to 16:00 hr each day recorded the location and visibility of quokkas. Data were analyzed using a two-factor ANOVA (visitor treatment and study area), with 2-day summary values as the unit of analysis. While the presence of quokkas in the study areas was not affected by treatment, fewer (p < 0.05) quokkas were visible from the visitor paths and more (p < 0.05) quokkas were obscured from the visitor paths in the "Open" treatment than the "Closed" treatment. Number of quokkas differed between study areas across treatments (p < 0.01), but there was no interaction (p > 0.05) between visitor treatment and study area. The reduction in quokka visibility when visitors were present indicates that visitors were at least moderately fear provoking for the quokkas in this experiment, but further research is required to examine the effects of visitor presence and behaviors on the behavior and stress physiology of quokkas in walk-through enclosures, as there may be possible welfare implications.

ItemThe Visitor Effect on Zoo Animals: Implications and Opportunities for Zoo Animal Welfare(MDPI AG, 2019-06-01)Achieving and maintaining high standards of animal welfare is critical to the success of a modern zoo. Research has shown that an animal’s welfare is highly dependent on how various individual animal factors (e.g., species traits, genetics, temperament and previous experience) interact with environmental features (e.g., social grouping, enclosure design and sensory environment). One prominent feature of the zoo environment is the presence of visitors. Visitor contact can be unpredictable and intense, particularly in terms of auditory and visual interaction. Depending on an animal’s perception of this interaction, visitors can have either negative, neutral or positive impacts on zoo animal behaviour and welfare. This paper reviews the literature on the implications and potential opportunities of human-zoo animal interactions on animal behaviour and welfare, with the aim of stimulating interest, understanding and exploration of this important subject. The literature to date presents a mixed range of findings on the topic. It is possible this variation in the responses of zoo animals to visitors may be due to species-specific differences, the nature and intensity of the visitor interactions, enclosure design, and individual animal characteristics. Analysing these studies and better understanding animal preferences and motivations can provide insight into what animals find negatively and positively reinforcing in terms of visitor contact in a specific zoo setting. This understanding can then be applied to either safeguard welfare in cases where visitors can have a negative impact, or, conversely, it can be applied to highlight opportunities to encourage animal-visitor interaction in situations where animals experience positive emotions associated with visitor interaction.

ItemThe Effect of Regulating Zoo Visitor-Penguin Interactions on Zoo Visitor Attitudes(FRONTIERS MEDIA SA, 2019-10-17)Understanding visitor attitudes toward zoo animals can inform the way zoos manage visitor-animal interactions by identifying the factors that may influence visitors and the way visitors interact with animals. Consequently, we investigated the relationship between visitor attitudes and penguin behavior and the effects of regulating visitor-penguin interactions on visitor attitudes and experience. Visitor attitudes toward little penguins (Eudyptula minor), their welfare, enclosure, visitor effects, enclosure manipulations and visitor experience at an Australian zoo were assessed. A 2 × 2 fully randomized factorial design was used to examine potential factors that may influence visitor attitudes: (1) Viewing proximity of visitors to the enclosure: "Normal viewing distance" and "Increased viewing distance" (using a physical barrier set up 2 m from the enclosure) and (2) Intensity of visitor behaviors: "Unregulated visitor behavior" and "Regulated visitor behavior" (using signage and researcher in zoo uniform). Visitor attitudes were assessed using an anonymous attitude questionnaire. Visitors were approached after they had finished viewing the penguins and were given two options to complete the questionnaire, either on an iPad on site during their zoo visit or online (URL sent via email) after their zoo visit. A total of 495 surveys (48% during zoo visit, 52% after zoo visit) were completed. Majority of respondents were non-zoo members, females and aged between 26 and 35 years old. Results revealed a significant relationship (p < 0.05) between little penguin behavior and visitor attitudes where the more visible, active and close penguins were to the visitor viewing area, the more positive several visitor attitude scales were. In contrast, there were only a few treatment effects of regulating visitor viewing proximity and behavior on visitor attitudes in which attitudes toward "Positive penguin characteristics" (p = 0.024), "Neutral visitor effects" (p = 0.0023) and "Physical barriers" (p = 0.013) were affected. This suggests that physical barriers and/or signage are factors that influence visitor attitudes. However, it is unclear if the treatment effects influenced visitor attitudes directly, or if it was the changes in penguin behavior as a consequence of the treatments that were associated with visitor attitudes. These findings have increased our understanding of the multifaceted nature of visitor attitudes and have identified some influencing factors on attitudes that can be used to inform the way zoos manage visitor-penguin interactions, but clearly further research is required.
