A Case Study Exploring the Use of Virtual Reality in the Zoo Context

Virtual Reality (VR) is now a popular tool in education and for engagement with the natural world, but to date little research has investigated its potential in a zoo setting. We aimed to gauge the interest of the visiting public in using VR technology at Royal Zoological Society of Scotland’s (RZSS) Edinburgh Zoo. A VR (n = 12) and a video condition (n = 12), both introducing the lives and conservation concerns of African wild dogs (Lycaon pictus), were used to gain greater insight of the thoughts and perceptions of how individuals evaluated a purpose-built VR experience and to enable comparisons of learning outcomes for both technologies. We used semi-structured interviews; responses were evaluated through thematic analysis and descriptive analysis. Younger participants (aged 13-18 years) emphasized that VR allowed them close and personal access to the animals. Adult participants (aged 19 and above) pointed out the entertainment value of the VR experience while highlighting the potential of its educational aspect; that of enabling visitors to see animals in their natural habitat. While our results require further confirmation due to the limited sample size and restricted circumstances of data collection, we suggest that VR could be usefully introduced as a public education and visitor engagement tool that would benefit the visitors’ learning and overall experience at the zoo.

Effects of Crowd Size, Composition, and Noise Level On Pool Use in a Mixed-Species Penguin Colony

Studies on how visitors affect penguins in human care report a mixture of negative, neutral, and positive impacts on behavior and physiology. Swimming is a highly motivated behavior that may promote positive welfare in penguins. We investigated how visitor crowd size, composition, and noise levels impact pool use in a mixed-species colony housing king (Aptenodytes patagonicus; n = 20), gentoo (Pygoscelis papua; n = 14), and southern rockhopper (Eudyptes chrysocome; n = 24) penguins. We used video and sound loggers to record if penguins were on land or in water, the number of human adults and children present, and noise levels using 5-minute scan samples from 09:00-15:00 over 36 continuous days. Data were analyzed using linear mixed models with proportion of penguins in the water as the dependent variable and crowd size, composition, and noise levels in A-weighted (dBA) and C-weighted (dBC) scales as independent variables. Crowd size was positively associated with pool use in gentoo penguins. Crowd composition did not predict pool use in any species. Noise levels in dBA, which is adjusted to the higher frequencies of human hearing, positively predicted pool use in southern rockhopper penguins. Noise levels in dBC, which captures lower frequencies, did not predict pool use in any species. No evidence of negative visitor effects was observed. Instead, these results suggest visitors are a neutral stimulus to king penguins and may be enriching to gentoo and southern rockhopper penguins.

'Bearly' Changing with the Seasons: Bears of Five Species Show Few Behavioral Changes Across Seasons and at Varying Visitor Densities

In natural environments, bear behavior follows seasonal patterns but the zoo environment differs from the natural environment in several ways, including the presence of zoo visitors. Although typically difficult to disentangle, we were able to tease apart the effects of seasonal changes and visitor density on the visibility and behavior of 10 bears representing five species housed at Cleveland Metroparks Zoo due to the disruption caused by COVID-19. We conducted a longitudinal bear behavior monitoring project from June, 2017-November, 2020. Bears were more visible in the spring and in the presence of visitors, locomoted more and were less inactive when large crowds were present, foraged and locomoted more when it was earlier in the day, and locomoted more at higher temperatures. There were limited differences in bear visibility to observers between 2020 (when the zoo was temporarily closed to visitors) and the previous three years. There were no differences in rates of stereotypy or social behavior across seasons, crowds, or daily attendance categories. Based on these limited differences, neither season nor visitor density seemed to have an apparent effect on bear behavior or welfare.

How is Western Lowland Gorilla (Gorilla gorilla gorilla) Behavior and Physiology Impacted by 360 Degree Visitor Viewing Access?

The effect visitors may have on the welfare of professionally managed animals is vital to consider. The present study utilized an experimental approach to examine how 360° visitor viewing access (i.e., viewing from all sides of the habitat) impacts the behavior and physiology of Western lowland gorillas (Gorilla gorilla gorilla, N = 7). Data collection included behavioral observations and obtaining fecal samples to examine physiological indicators of welfare. The study included a baseline period observing the gorillas’ behavior and physiology during the typical 360° visitor viewing access and a treatment period examining the same indicators but reducing viewing access by approximately 70%. Behavioral states, behavioral events, and hormone data were compared across conditions using Wilcoxon signed-rank tests. Restricted viewing did not impact social or solitary grooming (as a state behavior), social or solitary play, foraging, stereotypies, locomotion, inactivity, or behavioral diversity. However, restricted viewing significantly reduced solitary grooming events, fecal glucocorticoid metabolites, and the ratio of glucocorticoid metabolites to dehydroepiandrosterone metabolites. These results suggest that 360° visitor viewing access may have an impact on the welfare of gorillas. However, further research is necessary to thoroughly understand the influence of allowing 360° visitor viewing on behavior and its possible interaction with variables of the zoo environment.

Effects of Visitor Presence and Crowd Size on Zoo-Housed Red Kangaroos (Macropus Rufus) During and After a COVID-19 Closure

Macropods, particularly kangaroos and wallabies, are common species included in walk-through habitats that put them in close proximity to zoo visitors. However, there has been little research into how visitor presence and density impact the welfare of these individuals. We monitored the behavior and space use of fifteen red kangaroos (Macropus rufus) for a total of ten weeks during and after a nearly three-month zoo closure due to the COVID-19 pandemic. Our findings revealed potential visitor effects, evidenced by more time spent in social proximity, greater inactivity, and more restricted space use after the zoo reopened. Although temperature and weather likely played a role in at least some of these behavioral changes, social proximity and space use changed with crowd size in a manner consistent with our zoo status (i.e., open or closed) results. Additionally, time spent feeding was significantly related to crowd size but not zoo status, such that the kangaroos spent more time feeding when there were no visitors in the habitat. These findings suggest that visitor effects explain these behavioral changes better than seasonal confounds. We also noted several individual differences in response to visitor presence and crowd size, highlighting the importance of evaluating behavioral responses to visitors on an individual basis.

Animal-Visitor Interactions and the Visitor Experience: Visitor Behaviors, Attitudes, Perceptions, and Learning in the Modern Zoo

Animal-Visitor Interactions (AVIs) have become commonplace in zoological institutions and facilities globally. However, most AVI research focuses on the effects of visitors on the welfare of animals, with considerably fewer studies examining the visitor experience itself. Furthermore, robust evaluations of the efficacy of zoo education programs and engagements for increasing visitor awareness of conservation issues, and for fostering long-term pro-conservation behavior changes in them, are under-researched. This paper reviews the current literature that pertains to the effects of zoo visitation and AVIs on visitor perceptions, beliefs, and attitudes. We briefly note some of the known effects that zoo visitors have on zoo animals, then explore the effects that factors such as enclosure design, animal visibility and behaviors, and AVIs can have on visitors’ overall experience whilst attending the zoo. We suggest that future research needs to more closely examine the relationships and interactions between zoo visitors and zoo animals; why some zoo visitors over others repeat visitation; what the differences in beliefs and attitudes may be between “zoo visitors” and “non-zoo visitors” (i.e., other general public); and to make a concerted effort to understand: (1) what visitors do after they leave the zoo, and (2) whether visitors adopt long-term pro-conservation behaviors into their daily lives. We further suggest that future research needs to start investigating indirect measures related to the visitor experience, such as: (a) individual conservation support outside of the zoo; (b) internet activity; (c) changes in sustainable purchasing practices related to knowledge gains; (d) financial investment in sustainable or ethical companies after knowledge gains; (e) and the longitudinal effects of zoo visits.

Signs and Docents in Zoo Visitor Education: Using Affinitive Chimpanzee (Pan troglodytes) Behaviors

The goals of zoos are providing an entertaining and educational experience for visitors, promoting environmental conservation, and promoting positive welfare for nonhuman residents. Education can unify these goals. In this study, data were collected on visitors to the chimpanzee (Pan troglodytes) exhibit at The Zoo Northwest Florida. Researchers implemented three conditions of education at the chimpanzee viewing platform: a graphic sign, a trained docent, and a control condition with no intervention. The sign and docent encouraged visitors to use affinitive chimpanzee behaviors. Visitors were significantly more active in the graphic sign condition and significantly less active in the docent condition, and their behavior did not vary from the expected value during the control condition. Visitors used the affinitive behaviors that were demonstrated in each experimental condition. These results suggest that both graphic signs and docent interaction affect visitor behavior and can be considered useful educational tools for fulfilling the goals of the zoos.

Does Exposure to Animal Cognition Research Influence the Zoo Visitor Experience?

Zoos average about 183 million visitors per year, which makes them a major source for educating the public due to the diverse and wide-ranging demographic that visit. Zoos are increasingly a source of scientific research in a variety of subfields, including animal cognition, although much of this research takes place behind the scenes. Bringing this research to the public perspective has the potential to increase engagement of zoo visitors. However, it is not always possible to show live research, but videos have been found to be an effective educational approach in other domains. Here, we presented a brief video illustrating cognitive research involving sun bears at Zoo Atlanta to determine the potential effect on visitors. We measured several aspects of visitor behavior (stay time and actual behaviors in the exhibit), attitudes (towards both animal research and educational technology), and knowledge gained at the exhibit. We also presented a control video that focused on sun bear enrichment to tease out whether potential effects on visitors were related to the research focus of the video, or merely an effect of a video playing in the exhibit space. Visitor behavior, attitudes, and knowledge were determined by observing a randomly selected visitor’s behavior throughout their time in the exhibit space, and then requesting completion of a survey when they exited the exhibit (N = 148). We compared various aspects of behavior, attitudes, and knowledge across the Scientific Video, Enrichment Video, and No Video conditions. There were no differences between the Scientific Video and the Enrichment Video conditions; however, some differences were found between visitors who experienced a video during their visit (scientific or enrichment video) versus those who did not. Attitudes towards technology in the exhibit space were generally positive. There was also a significant correlation between visitor stay time (overall time spent in the exhibit space) and knowledge gained. Visitors learning about research in zoos remains important, but it is unclear if a video is a sufficient means to share that information.

Animal-Visitor Interactions: Effects, Experiences, and Welfare

Animal-Visitor Interactions (AVI) within zoos and aquariums have become an increasingly studied topic. Influenced by both the broader field of Human-Animal Interactions (HAI), as well as visitor studies conducted in museums, AVI studies can be separated into two areas of focus: (1) Visitor effects, or the impact visitors have on the animals housed within a zoo, and (2) visitor experiences, or the impact zoo animals and visiting a zoo have on the visitors. Historically, visitor effects have been of primary concern to the study of AVIs, as have the potential negative impacts on the welfare of animals, particularly those of zoo primates. This special issue examines the impact of AVIs in greater detail through twelve recent papers on the topic, equally addressing visitor effects and experiences. Many of the papers focus on positive welfare indices, as well as less traditional measures to examine both visitor effects and experiences, such as visitor proximity and visitor interviews. In addition, we discuss the relevance of future AVI work, with particular attention to (a) increased interest in visitor experience research, (b) examinations of signage effects, and (c) continued focus on positive welfare indices and direct interactions, such as public feedings.

Behavioral Responses of Captive Corvids to the Presence of Visitors

Behavioral responses of captive animals to the presence of visitors in zoos and wildlife parks can be interpreted as signs of negative (disturbance), neutral or positive (enrichment) welfare. In the present study, we investigated behavioral responses of captive common ravens, Corvus corax and crows, Corvus corone, to the presence of visitors in general and to the proximity or distance of visitors to the aviary respectively. Duration of affiliative behaviors, feeding and stress-related behaviors did not change when visitors were present compared to control situations without visitors being present. Both corvid species showed less head up behavior when visitors were in sight compared to the control condition. In contrast, preening of crows significantly increased when visitors were within two meters of the aviary compared to the control condition. The same relationship was found in regard to increase in vocalization for common ravens, but not for crows. Our results indicate that corvids, housed in a wildlife park for several years, still show behavioral responses to the presence of human visitors in close proximity to their enclosure. Overall, we did not find clear indications for reduced welfare due to visitor presence, such as increased locomotion or stress-related behaviors. We therefore conclude that the described behavioral changes are not indicative of any negative welfare impacts of visitor presence.
