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.     

An hourly variation in zoo visitor interest: measurement and significance for animal welfare research

A methodological difficulty facing welfare research on nonhuman animals in the zoo is the large number of uncontrolled variables due to variation within and between study sites. Zoo visitors act as uncontrolled variables, with number, density, size, and behavior constantly changing. This is worrisome because previous research linked visitor variables to animal behavioral changes indicative of stress. There are implications for research design: Studies not accounting for visitors' effect on animal welfare risk confounding (visitor) variables distorting their findings. Zoos need methods to measure and minimize effects of visitor behavior and to ensure that there are no hidden variables in research models. This article identifies a previously unreported variable—hourly variation (decrease) in visitor interest—that may impinge on animal welfare and validates a methodology for measuring it. That visitor interest wanes across the course of the day has important implications for animal welfare management; visitor effects on animal welfare are likely to occur, or intensify, during the morning or in earlier visits when visitor interest is greatest. This article discusses this issue and possible solutions to reduce visitor effects on animal well-being.

Postoccupancy evaluations in zoological settings

A postoccupancy evaluation (POE) is a systematic assessment performed to examine the effectiveness of the built environment after occupation. Although POEs have been mainly used to examine the effectiveness of built environments for human usage, they can and should be adapted for use in zoological settings. Zoological exhibits have evolved from when hygiene concerns ruled design to current trends that involve elaborate exhibits that often cost millions of dollars. Thus, it is imperative to conduct evaluations to ensure that these exhibits function to meet the complex needs of all users. It is crucial to perform a comprehensive POE that focuses on all three user groups; animals, visitors, and staff. However, work in this field is limited. Animal research has tended to remain very primate-focused with differing opinions as to what constitutes optimal outcomes. Zoo visitor studies often have limited scope and differing methodologies. Additionally, research on zoo staff opinions and feedback is almost nonexistent. A new exhibit opening at a zoo has huge potential for improving the welfare of the animals it will house, enhancing the zoo visitor experience, and improving the workplace for zoo personnel. Building the best possible exhibits requires not only the analysis of how the built environment affects all three groups, but also dissemination of those findings to guide future design.     

Impacts of natural history and exhibit factors on carnivore welfare

To improve the welfare of nonhuman animals under professional care, zoological institutions are continuously utilizing new methods to identify factors that lead to optimal welfare. Comparative methods have historically been used in the field of evolutionary biology but are increasingly being applied in the field of animal welfare. In the current study, data were obtained from direct behavioral observation and institutional records representing 80 individual animals from 34 different species of the order Carnivora. Data were examined to determine if a variety of natural history and animal management factors impacted the welfare of animals in zoological institutions. Output variables indicating welfare status included behavioral diversity, pacing, offspring production, and infant mortality. Results suggested that generalist species have higher behavioral diversity and offspring production in zoos compared with their specialist counterparts. In addition, increased minimum distance from the public decreased pacing and increased offspring production, while increased maximum distance from the public and large enclosure size decreased infant mortality. These results have implications for future exhibit design or renovation, as well as management practices and priorities for future research.     

Use and non-use values as motivational construct dimensions for farm animal welfare: impacts on the economic outcome for the farm

This study explored how farmers’ motivation in terms of use values and/or non-use values to work with farm animal welfare are associated with the economic outcome for the farm. Use values in farm animal welfare refer to economic value derived from productivity and profitability considerations. Non-use values in farm animal welfare refer to economic value derived from good animal welfare, irrespective of the use the farmer derives from the animal, currently or in the future. The analysis was based on detailed information about the income statements of a sample of Swedish dairy farmers, obtained from the Swedish Farm Economic Survey, complemented with survey information about their perceived use and non-use values in farm animal welfare. The findings suggest that farm economic outcome is significantly associated with motivation in terms of use values, but not so much with motivation in terms of non-use values. This is interesting from a policy point of view, because it indicates that farmers with different approaches to farm animal welfare may experience different economic outcomes for their farms. Findings can, for instance, be used to strengthen farmers’ engagement in various private quality assurance standards, which generally focus on values of non-use type, by pointing to that realisation of such values will not impair the economic outcome of the farms. Moreover, findings also suggest that farmers’ economic incentives for engagement in such standards may need to be further strengthened in order to become more attractive, as findings point to that a focus on non-use values generally is not associated with more favourable economic outcomes.     

Visitor Circulation and Nonhuman Animal Welfare: An Overlooked Variable?

This article investigates visitor circulation and behaviors within a gallery of primate exhibits in relation to their possible implications for nonhuman animal welfare. When entering a primate house, the majority of visitors (84%) turned right, a pattern upheld throughout all times of the day. These findings demonstrate the existence of the "right-turn" principle, a concept previously identified and investigated in the museum setting. The existence of this circulation pattern in zoos has important implications for the practical management of animal welfare issues because unbalanced or large numbers of visitors at specific enclosures could present a stressful influence. The "direction bias" could not be attributed to demographic or behavioral traits, therefore suggesting that the principle, like similar findings from museum research, generalizes across visitor populations and, therefore, zoos. A visitor sample at another exhibit (located outside the exhibit gallery) did not display a direction bias, suggesting that the marked circulation pattern may be specific to exhibit galleries. The article discusses the significance and consequences of visitor circulation with respect to visitor management and animal welfare.     

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 reaction to pacing behavior: influence on the perception of animal care and interest in supporting zoological institutions

Many publications within the field of zoo animal welfare have stated the importance of decreasing stereotypic behavior (e.g., pacing) to help ensure a positive visitor experience. The idea behind these statements is that visitors want to see animals engaged in natural behavior. Additionally, it is thought that watching an animal exhibit species-appropriate behavior could help increase a visitor's connection to wildlife and ultimately their interest in conservation. However, until recently, no information was available to validate such statements. The purpose of this research was to examine people's reaction to viewing an animal engaged in pacing behavior. Participants were randomly selected to fill out a survey after watching a short video of either a tiger pacing or resting (control). Results indicate that having viewed a tiger pacing significantly decreases people's perception of the level of care animals receive at that facility. In addition, people's interest in supporting zoos decreased as a result of viewing this behavior. Results are discussed from an animal welfare, business, and conservation perspective.

A Case for a Naturalistic Perspective: Response to Lawrence and Bekoff

ABSTRACT

We evaluated three forms of primate free-ranging displays at Singapore Zoo, each with varying restrictions on ranging area and freedom for the primates, as well as visitor proximity. The cotton-top tamarin (Saguinus oedipus), the white-faced saki (Pithecia pithecia), and the orangutan (Pongo pygmaeus) displays illustrated differences in primate visibility to visitors, visitor–primate proximity, frequency of visitor–primate interactions, visitor crowd size, and responses. Amongst the three free-ranging displays, the cotton-top tamarins offered the highest visibility, closest proximity between visitors and primates, highest interaction levels, and attracted the largest crowds. However, undesirable interactions occurred most between the cotton-top tamarins and visitors. We found consistently positive visitor perceptions (total n = 464) of all three primate displays in terms of visitor enjoyment (> 95%); naturalistic zoo experience (> 95%); learning experience (> 90%); and the promotion of good welfare (> 90%). Increasingly naturalistic displays of animals in zoos through the free-ranging of animals can have considerable benefits for both zoo visitors as well as animals, and is a display concept that deserves implementation on a wider scale. Design and implementation of such displays should, however, achieve a balance to maximise display value and animal welfare while curtailing the effects of undesirable human–primate interactions through the restriction of visitor–primate proximity.     

Visitors' Effects on the Welfare of Animals in the Zoo: A Review

Since the 1970s, research about zoo visitors' effects on the welfare of nonhuman animals in captivity has intensified. Numerous studies have shown that characteristics such as visitor presence, density, activity, size, and position are associated with animal behavioral and—to alesser extent physiological—changes. Studies usually interpret these changes as negative (undesirable) or positive (enriching), but it remains unclear whether they significantly impinge on animal welfare. To make confident conclusions about visitors' effects necessitates more studies using (a) a wider range of animal groupings, (b) measures of stress, (c) visitor-animal variables, and (d) other methodological improvements In the meantime, in addition to further research, individual zoos need to emphasize (a) monitoring the stress indicators of their captive animals, (b) observing visitor behavior, and (c) ensuring that staffs are aware of the “visitor effect” concept.

Undergraduate animal behavior program: Teaching and research

The purpose of this paper is to present strategies for teaching animal behavior within a mixed traditional and nontraditional format. Based on our experience, it is very useful to use zoological parks as convenient locales for observational studies. Students gain many valuable experiences in a nontraditional course such as this. Various suggestions are made for animal behavior courses and student projects. Some of the potential pitfalls and problems associated with an animal behavior course are also discussed. Finally, future directions are suggested.     

Impact of zoo visitors on the fecal cortisol levels and behavior of an endangered species: Indian blackbuck (Antelope cervicapra L.)

This study investigated behavioral activities (resting, moving, aggressive, social, and reproductive behavior) and fecal cortisol levels in 8 individually identified adult male blackbucks during periods of varying levels of zoo visitors (zero, low, high, and extremely high zoo visitor density). This study also elucidated whether zoo visitor density could disturb nonhuman animal welfare. This study analyzed fecal cortisol from the samples of blackbuck by radioimmunoassay and found significant differences (p < .05) for time the animals devoted to moving, resting, aggressive, reproductive, and social behavior on days with high and extremely high levels of zoo visitors. The ANOVA with Duncan's Multiple Range Test test showed that the fecal cortisol concentration was higher (p < .05) during the extremely high (137.30 ± 5.88 ng/g dry feces) and high (113.51 ± 3.70 ng/g dry feces) levels of zoo visitor density. The results of the study suggest that zoo visitor density affected behavior and adrenocortical secretion in Indian Blackbuck, and this may indicate an animal welfare problem.     

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.     

The effectiveness of indigestible markers for identifying individual animal feces and their prevalence of use in North American zoos

Techniques for analyzing hormone metabolites in animal excreta have created many opportunities for noninvasive monitoring of health, reproduction, and welfare in zoo animals, but can be difficult to implement when individual samples are not readily identifiable in animal groups. A common approach to this problem is to feed animals an indigestible marker that subsequently appears in feces, but there has been little systematic research on the use of such “fecal markers.” First, we used an online survey to assess the prevalence of fecal marker use in North American zoological institutions. Second, we conducted a series of experimental tests utilizing commonly employed fecal markers in a variety of typical zoo taxa to determine the: (1) effectiveness of several markers to accurately distinguish samples in a variety of species, (2) minimum quantity of marker needed for detection, and (3) length of time between ingestion and detection in the feces. The majority of the 45 institutions that completed the survey reported using fecal markers with their collections. The survey also revealed that the most frequently used markers are seeds/grains and food colorants, with the former generally used in Carnivora and the latter in Primates. Our experimental data confirmed the success of these taxa/marker combinations and also revealed that food colorants function as markers in a variety of avian, reptilian, and mammalian species. Our data describe successful fecal markers for a wide variety of zoo taxa and should, therefore, be useful for zoological managers and researchers needing to employ fecal markers in future investigations.

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.

The results of the study suggest that zoo visitor density affected behavior and adrenocortical secretion in Indian Blackbuck, and this may indicate an animal welfare problem.     

Examining the Impact of Naturalistic and Unnaturalistic Environmental Enrichment on Visitor Perception of Naturalness,Animal Welfare,and Conservation

Recent research shows that using different types of enrichment has little to no impact on how zoo visitors perceive the animals or the enclosure in general. The primary objective of the current research was to examine if viewing naturalistic-looking environmental enrichment (NEE) and unnaturalistic-looking environmental enrichment (UEE) has an effect on visitor perceptions of exhibit naturalness, animal welfare, and conservation, while controlling for two factors that can influence visitor perspective: animal visibility and behavior. Study 1 examined the color of enrichment: the NEE was colored to resemble a rock and the UEE was fluorescent pink. Four conditions were recorded: Naturalistic/No Animal, Naturalistic/Animal, Unnaturalistic/No Animal, and Unnaturalistic/Animal. One video was shown to 306 randomly selected visitors who then took a survey including questions on animal welfare, exhibit naturalness, and supporting conservation organizations. Naturalistic/No Animal was perceived by visitors to be the most natural environment and the best of the exhibits for an animal to live in. Study 2 examined different types of NEE and UEE. Eight photos (four with an animal and four without) showing one out of four enrichment items (naturalistic rock, wood wool bedding, traffic cone, cardboard box) were shown to 618 randomly selected visitors who then took a survey similar to study 1. Visitors rated the photos with the NEE consistently higher for questions regarding the naturalness of the exhibit, good animal welfare, and the livability of the environment. Visitors were also asked to rank the four enrichment items from best to worst, and the NEEs were ranked significantly higher than the UEEs. While there are still many unanswered questions regarding visitor perceptions of environmental enrichment in zoos, we hope that focusing on one variant such as color and examining different types of NEE and UEE can help guide future studies on this subject.
