Postoccupancy evaluation of staff,visitors, and three species of animals in a zoo setting

Postoccupancy evaluation (POE) was used to assess newly constructed zoo exhibits from the perspective of three user groups: zoo staff, zoo visitors, and the animals. Staff represents a generally understudied user group in zoo-based POEs. We asked staff to rate the animals' space, the visitors' space, and the staff's space at previous and new exhibits. We also compared zoo visitors' ratings of the animals' behavior and environments, overall exhibit impressions, and the time visitors spent viewing previous and new exhibits. Lastly, we compared activity and space use of a Komodo dragon (Varanus komodoensis), two red pandas (Ailurus fulgens), and one rhinoceros (Rhinoceros unicornis) in their previous and new exhibits. Staff rated animal, visitor, and staff areas higher at the new exhibits compared to the previous exhibits. Visitors also rated several factors higher and spent more time at the new exhibits. The most naturalistic exhibit received the most favorable ratings in all categories and animal activity increased visitor stay time. We found that red pandas were less active in their new exhibit, and the Komodo dragon and rhino showed no difference in activity. The red pandas and the Komodo dragon used more available space in their new exhibits; however, we recommend using Electivity index to examine resource preferences for these species, whose enclosure use has been less studied than large mammals. We emphasize the importance of including staff in zoo-based POE, make other recommendations for future POE studies, and discuss various factors that could have influenced our results.     

Post-occupancy evaluation in the zoo

Post-occupancy evaluations (POE) of the built environment provide systematic information about the success or failure of environmental designs. Research instruments developed for application in human settings can also be adapted for use in zoos. The zoo environment must be evaluated for its impact on animal residents, zoo visitors and staff. Evaluations conducted by our Atlanta research team included studies of the Atlanta Zoo and zoos in nearby cities. The range of available methodologies are reviewed, and the unique constraints of zoo settings are discussed. Our studies indicate that naturalistic environments facilitate the expression of normal and complex animal behavior patterns and tend to enhance the visitor experience. POE represents an exciting new dimension in zoo research and promises to contribute to the success of future generations of zoo design.     

Zoo‐housed mammals do not avoid giving birth on weekends

There is evidence that zoo visitor presence can influence the behaviour and, in some cases, adrenal response of zoo animals, and can sometimes compromise animal welfare. In some laboratory studies, significantly more primate births have been reported on weekends, when fewer people are working there, compared with weekdays when staffing levels are at their highest. Here, we investigate whether there is evidence of a “weekend effect” on births in zoo animals as a result of visitor numbers. Unlike laboratories, zoos are typically busier with visitors on weekends than on weekdays, although staffing levels remain fairly consistent across days of the week. If zoo animal parturition is sensitive to human presence, then fewer births would be expected on weekends compared with weekdays. We tested this using birth data and visitor numbers on the entrance gate from zoo records across 16 species representing artiodactyls, perissodactyls, carnivores and primates at four British zoos, to see whether there is an association between mean daily birth rates and average visitor numbers. We predict that, if there is a visitor effect, daily births should be lower on weekends than weekdays and should correlate with mean daily visitor numbers. Results showed that births for all 16 species were randomly distributed through the week, and there was no significant decline in births on weekends. We conclude that the “weekend effect”, if such a thing exists, does not appear to be a feature of zoo births, suggesting that elevated weekend visitor numbers are not sufficiently stressful to trigger delayed parturition.     

Relationships between exhibit naturalism,animal visibility and visitor interest in a Chinese Zoo

Efforts to meet the welfare needs of captive animals (such as the provision of environmental enrichment and naturalistic furnishings) often compromise visitors’ needs (naturalistic exhibits often decrease the visibility of animals on display even though visitors pay to view them). The literature offers different predictions about how zoo visitors respond to decreased animal visibility in naturalistic exhibits but they require further evaluation. Further, visitor research is currently confined to Europe and America and studies outside these areas are limited. This paper investigates the relationships between exhibit naturalism, animal visibility and visitor interest in a Chinese Zoo. Visitor interest was observed at both naturalistic and barren exhibit designs. The study showed that the influence of animal presence on visitor behaviours was similar at both exhibit designs. Further, visitor interest was not compromised at the naturalistic exhibit when animals were not visible. The results demonstrate that the needs of animals and visitors can be balanced at naturalistic exhibits and support the transformation of exhibits to those representing naturalistic environments.     

Visitor interest in zoo animals and the implications for collection planning and zoo education programmes

As zoos have sought to further their conservation missions, they have become powerful providers of environmental education. Outside of “formal” education initiatives, such as those designed for school and other organized groups, or structured public talks programmes, much of the learning potential that the zoo has to offer is around the viewing of animals and the response of visitors to them. In this, zoo learning is a very personal construct, develops from the previous knowledge, and experiences and motivations of each individual. In this article, we make the assertion that learning potential, although difficult to quantify, is very much related to the attractiveness of animal species and the interest that visitors show in them. Using standard behaviorist measures of attraction and interest (the proportion of visitors that stop and for how long), we analyzed the relative interest in 40 zoo species held in a modern UK zoo and the variables that are significant in predicting that popularity. Further to this, the suggestion is made that the zoo collection planning process could use such information to make more informed decisions about which species should be housed for their educational value. Taxonomic grouping was found to be the most significant predictor of visitor interest—that is, visitors were far more interested in mammals than any other group—although body size (length), increasing animal activity and whether the species was the primary or “flagship” species in an exhibit or not, were all found to have a significant bearing on visitor interest.

The gap in technology for visitor experience in a zoo: A case study in Indonesia

Technology has routinely been used in zoos to enhance the visitor experience, for public education and for conservation awareness. However, studies into technology-aided exhibits in zoos have thus far been limited to zoos in western society. This article reports on an Indonesian zoo deploying new technology in its exhibits and how visitors interacted with these exhibits. A case study guided both an investigation of the visitors' technology usage of zoo exhibits and zoo implementation of technological processes. Interviews with visitors, zoo staff, and managers were conducted and analyzed and these were supplemented with on-site observations. The results indicated that the majority of zoo visitors did not use the technological applications provided by the zoo. In addition, there was found to be a significant lack of staff engagement in the consultation, design, implementation, and maintenance of the technology. Correlations were found between visitors' level of technology usage, their reading of signage, their day-to-day technology usage, and their conservation knowledge. The findings suggest that an understanding of visitor' behavior, active staff engagement in the development and implementation of new technology, in addition to emotion-inducing interpretation, and purposefully guided interactions, could increase the use of technology at a zoo and thus enhance positive visitor engagement, ultimately resulting in heightened educational as well as conservational outcomes.     

Assessing the Effects of New Primate Exhibits on Zoo Visitors' Attitudes and Perceptions by Using Three Different Assessment Methods

ABSTRACT

Using three different methods, this study investigated how zoo visitors behaved in response to both old and new exhibits of four nonhuman primate species and how they perceived these primates. On-site observations showed that zoo visitors were more likely to stop in front of new exhibits and spend more time viewing new exhibits compared with old exhibits. Response to an on-site questionnaire also showed that zoo visitors perceived primates in the new exhibits more positively than the same animals in the old exhibits. The results from these two types of local assessment indicate that the attractiveness and holding power of the new exhibits was greater than that of the old. However, the results of a questionnaire given to zoo visitors on leaving the zoo showed that the preference ranks of the visitors for the four primate species did not increase after the new exhibits were established, indicating that the new exhibits did not change the zoo visitors' perception of primates relative to other zoo animals. Using all three assessment methods appears to be of considerable value for the assessment of visitors' perceptions towards new exhibits in terms of both the immediate locality and the zoo as a whole.     

Visitor behavior in the National Zoo's reptile house

Visitor behavior was evaluated in the National Zoo's reptile house. Nearly 600 visitors were tracked; time spent in the house and time spent looking at exhibits were noted. These parameters were investigated by sex, age, and type of visitor grouping. The most looked-at exhibits were determined. For 573 visitors, the mean time in the reptile house was 14.7 minutes. Only about 8 minutes was spent looking at exhibits, and this time was strikingly similar for age, sex, and group type. Time spent looking at exhibits was negatively correlated with visitor density. Amphibians and lizards were looked at for less time than snakes and turtles. Crocodilians were looked at longer than the other taxonomic groups, while larger animals in all groups were looked at longer than smaller ones. This study and other similar studies imply that the public does not respond to exhibits with the expected interest and enthusiasm. It is hoped that with a better understanding of the public through research, zoo staff can improve visitor interest in the exhibits.     

Effect of felid activity on zoo visitor interest

The extent to which the presence of zoo visitors influences animal behavior, and the ways in which animal activity influences visitor interest and perception, are of great interest to zoological parks. Visitors have been variously characterized as being enriching for zoo animals, as being stressors, and generally as influencing behavior in measurable ways. Most studies have focused on primates, and have assumed a “visitor effect” paradigm (i.e., visitors influence animal behavior). Here we present findings from a study of a nonprimate group (felids), and examine the “visitor attraction” model, which assumes that visitors are attracted to active animals. We assessed visitor interest and number at seven cat exhibits at the Brookfield Zoo during the spring and summer of 2002. Data were collected during 1‐min scans of each exhibit at 10‐min intervals. The results indicate that visitor presence per se did not influence cat activity, and that visitor interest was generally greater when cats were active. Various species differences may be explained by visitor familiarity with the species, variations in exhibit design, and species‐specific activity budgets. We conclude that the visitor attraction model may be more appropriate for taxa, such as large cats, that tend naturally to be largely inactive and to respond little (if at all) to visitor disturbances or efforts to engage. The relationship must be viewed as bidirectional: visitors influence animal behavior, and animal behavior influences visitor interest. However, the strength and primary direction of this relationship is likely taxon‐specific. We suggest that a visitor attraction model may be more appropriate not only for felids, but for other taxa with similar behavioral patterns and responses as well.

Visitor behavior in zoos: A review

Abstract

Visitors are integral components of zoological parks and their importance has led to a research area devoted to understanding the people–zoo relationship. This paper reviews, and provides a point of entry into, the literature relating to visitor research in zoos. The field emerged relatively recently and is diverse and interdisciplinary (it shares common ground with sociology, education, psychology, zoology, and other academic disciplines). Several areas can be identified in the literature (audience analysis, circulation and orientation, exhibit evaluation, and interactions with animals), and these areas have revealed visitors' demographic and behavioral characteristics, people's behavioral responses to endogenous and exogenous factors, the impact of exhibit design, and visitors' movements around zoos. Limitations of existing work include independence between research areas, lack of international studies, limited generalizability of results, and the minority status of the field. Therefore, suggestions for future work include integrating different research areas, more research from outside Europe and America, and increased interaction within the visitor research community.     

Visitor effects on a zoo population of California sea lions (Zalophus californianus) and harbor seals (Phoca vitulina)

The effects of visitor presence on zoo and aquarium animals have become increasingly well studied, using measures such as behavioral responses and exhibit usage. Many taxa remain underrepresented in this literature; this is the case for marine mammals, despite widespread public concern for their welfare in managed care settings. The current study therefore used behavioral activity budgets and exhibit usage to assess the responses of California sea lions (Zalophus californianus) and harbor seals (Phoca vitulina) to visitors at the Seal Cove exhibit at Six Flags Discovery Kingdom, Vallejo CA. Data was collected via focal follow video recordings over the summer season of 2016, and analyzed using MANCOVAs, discriminant analyses, and modified Spread of Participation Indices. The sea lions showed no significant changes in behavior when visitors were present, but did show greater preference for the water bordering visitor viewing areas during these times. Two sea lions gave birth during the study period, and showed greater preference for land areas both adjacent to and out of sight of visitors when nursing compared to while pregnant. In contrast, the harbor seals showed significant behavioral changes in the presence of visitors, including increased vigilance and feeding. This was associated with increased preferential use of water areas adjacent to the visitor viewing area. Visitors were able to purchase fish to throw to the animals, which likely contributed to the differences observed. Overall, this study found little evidence for negative visitor impacts on two pinniped species in a zoo setting.     

The Bielefeld teaching program in zoo biology

The teaching program in zoo biology of the University of Bielefeld offers a 4-week course that aims at providing special knowledge of zoos and zoo animals from theoretical, educational, and applied points of view. The course includes 1 week each of seminar-type lectures, a 1-week visit to one particular zoo, “comparative” 1-day visits to different zoos, and reports and seminars to be given by the participants. During the “zoo week” the students are required to select one of the exhibits and to make full-day behavioral observations of the animals. Requirements include seminar talks, a protocol about the observations, and the design of a label.     

What Is the Future for Zoos and Aquariums?

ABSTRACT

Animal welfare concerns have plagued the professional zoo and aquarium field for decades. Societal differences remain concerning the well-being of animals, but it appears a shift is emerging. Scientific studies of animal welfare have dramatically increased, establishing that many previous concerns were not misguided public empathy or anthropomorphism. As a result, both zoo and aquarium animal welfare policy and science are now at the center of attention within the world’s professional zoos and aquariums. It is now possible to view a future that embraces the well-being of individual captive exotic animals, as well as that of their species, and one in which professional zoos and aquariums are dedicated equally to advancing both. Though the ethics of keeping exotic animals and animals from the wild in captivity are still a contentious subject both outside and even within the profession, this study argues. We argue that this path forward will substantially improve most zoo and aquarium animals' welfare and could significantly reduce societal concerns. If animal welfare science and policy are strongly rooted in compassion and embedded in robust accreditation systems, the basic zoo/aquarium paradigm will move toward a more thoughtful approach to the interface between visitors and animals. It starts with a fundamental commitment to the welfare of individual animals.     

Public perceptions of behavioral enrichment: Assumptions gone awry

More and more, zoos are integrating behavioral enrichment programs into their management routines. Given the newness of such programs on an official level, however, there are an increasing number of enrichment decisions based on assumption. Enrichment is typically not provided on exhibit, especially for exhibits considered to be more naturalistic, because it is assumed to affect visitors' experience negatively. To test that assumption, visitors were interviewed in front of four exhibits—an outdoor barren grotto, an outdoor vegetated grotto, an indoor immersion exhibit, and an outdoor traditional cage—each with either natural, nonnatural or no enrichment objects present. Specifically, we wanted to know whether (1) the exhibit's perceived educational message, (2) the animal's perceived “happiness,” and (3) the visitor perceptions of enrichment, the naturalism of animal's behavior, and zoo animal well-being changed as a function of object type. Overall, the type of enrichment object had little impact on visitor perceptions. In the outdoor barren grotto, only visitor perceptions of exhibit naturalism were affected by object type. In the outdoor vegetated grotto, object type influenced visitors perceptions of enrichment and exhibit naturalism. For the indoor immersion exhibit, general perceptions of enrichment and the perceived naturalism of the animal's behavior were affected. Finally, in the outdoor traditional cage, perceived educational message and general perceptions of enrichment changed as a function of object type.

It's a sign: Animal welfare and zoo type are predictors of animal identification signage usage and quality at zoo exhibits

Conservation education programs are listed as priority actions for almost every threatened species on the International Union for Conservation of Nature Red List. Zoos play an important role in delivering such programs, yet evidence of zoo education in many non-western countries is limited. Here, we evaluate animal identification signage prevalence and quality at zoo exhibits and investigate whether animal welfare, zoo type (accredited, government, and private), admission fee, zoo size, and proximity to urban centers are influencing factors. We used hornbills (Bucerotidae) as a model taxon, surveyed hornbill signage, and conducted welfare assessments of hornbill exhibits. We developed scoring frameworks and applied content analysis to analyze signage quality. Our results show that out of 18 zoos that displayed hornbills, 15 had hornbill signage. However, of the 106 hornbill exhibits in these zoos, 33% had no signage. We also found that signage presence or absence at individual zoos and signage quality is strongly correlated with animal welfare quality. Zoo type is a key factor in predicting signage and welfare quality, with accredited zoos scoring highest for both signage and welfare, followed by government and private zoos. Private zoos charged higher admission than other zoo types, and zoo size and proximity to urban centers did not influence signage or welfare scores. Overall, we conclude that in our study, signage usage and quality are inadequate, highlighting the importance of compliance with robust zoo standards to improve education and welfare within zoos to support global conservation goals.

The Role of Zoos in Modern Society—A Comparison of Zoos' Reported Priorities and What Visitors Believe They Should Be

Modern zoos are required to fulfill a growing number of responsibilities including scientific research, wildlife conservation, public recreation, and education. With so many roles and responsibilities and limited funds, zoos have to prioritize their activities in relation to their own specified goals, objectives, and mission statements. Given their desire to nurture community relations and educational opportunities, it is important to determine the extent to which zoos are prioritizing their activities, according to visitors' expectations. This paper presents empirical research of a two staged mixed-methods investigation into zoo priorities from both zoos' and visitors' perspectives. The first stage involved an online questionnaire to which more than 190 zoos across 52 countries reported their priorities and activities. We then undertook in-depth case studies in nine institutions, enabling direct observation of each site within its context, including face-to-face visitor interviews. Our research contrasts the priority given to zoo activities from each perspective and indicates that educating visitors, including school children, is the highest priority activity from the zoos' perspective and that of their visitors. The findings also show that visitors place high value on learning about actions they can take to help conservation efforts. Some inconsistencies between zoos' and visitors' priorities were also evident, such as the different emphasis placed on viewing endemic species, and zoos being a place for people to relax and socialize. The implications of these findings are discussed.     

Technology at the Zoo: The Influence of a Touchscreen Computer on Orangutans and Zoo Visitors

A computer‐controlled touchscreen apparatus (hereafter referred to as “touchscreen”) in the orangutan exhibit at Zoo Atlanta provides enrichment to the animals and allows cognitive research to take place on exhibit. This study investigated the impact of the touchscreen on orangutan behavior and visibility, as well as its impact on zoo visitors. Despite previous research suggesting that providing a single computer system may negatively affect orangutan behavior, there was not a significant increase in aggression, stereotypic, or distress‐related behaviors following the activation of the on‐exhibit touchscreen. We also investigated the possibility that zoo visitors may be negatively affected by technology because it deviates from naturalism. However, we did not find a change in stay time or overall experience rating when the computer was turned on. This research was the first to assess visitor attitudes toward technology at the zoo, and we found that visitors report highly positive attitudes about technology for both animals and visitors. If subjects visited the exhibit when the computer was turned on, they more strongly agreed that orangutans benefit from interacting with computerized enrichment. This study is the first investigation of an on‐exhibit touchscreen in group‐housed apes; our findings of no negative effects on the animals or zoo visitors and positive attitudes toward technology suggest a significant value of this practice.

Dither: A unifying model of the effects of visitor numbers on zoo animal behavior

Interest in the impact of human presence on the behavior and well-being of zoo and aquarium animals is increasing. Previous work has conceptualized the presence of zoo visitors as having one of three impacts on the behavior of animals in zoos: positive, negative, or neutral. Research suggests the same species may exhibit all three responses under different conditions, calling into question whether the positive/negative/neutral framework is the most useful way of considering visitor impact on animal behavior. Here we present a model of visitor effects that unifies these three predictions. Our model suggests that zoo-goers may provide a “dither effect” for some animals living in zoos. We posit animals may show nonlinear behavioral responses over a range of visitor densities, effectively exhibiting changes in both comfortable and anxiety-like behaviors under different levels of human presence. We tested this model during two COVID-19 related closures at the San Francisco Zoo, studying seven species for evidence of nonlinear relationships between visitor numbers and animal behavior. Our results support the dither effect acting in several species observed.
