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.     

Environmental influences on stereotypy and the activity budget of Indian leopards (Panthera pardus) in four zoos in Southern India

To eliminate abnormal behaviors in leopards (Panthera pardus), such as stereotypic pacing, by utilizing environmental enrichment techniques, a proper understanding of their behavior in captive environments is required. Hence there is a need for animal welfare studies in Indian zoos. The activity budgets of 16 leopards were recorded across four southern Indian zoos: Thiruvananthapuram Zoo, Arignar Anna Zoological Park, Shri Chamarajendra Zoological Gardens, and the Guindy Children's Park. Of the 16 study animals, 14 were studied on‐exhibit on zoo holidays as well as on days with visitors present, and all 16 individuals were studied off‐exhibit on other days with visitors present. The 11 behaviors recorded were categorized into active, resting, and stereotypic behaviors. Leopards exhibited higher levels of activity in the on‐exhibit enclosures on days with no visitors. Feeding time influenced the behavioral repertoire of all 14 leopards studied on‐exhibit. Lower proportions of resting were exhibited during the hours before feeding. The proportion of active behaviors differed significantly across zoos. Stereotypic pacing levels were not influenced by the presence of visitors or by feeding time, but was significantly influenced by enclosure features. Higher levels of stereotypic pacing were exhibited in off‐exhibit than on‐exhibit enclosures. Our study shows that the behavior of captive leopards is influenced by enclosure type, feeding regime, and the presence of visitors. Zoo Biol 21:585–595, 2002. © 2002 Wiley‐Liss, Inc.     

Influence of Zoo Visitor Presence on the Behavior of Captive Indian Gaur (Bos gaurus gaurus) in a Zoological Park

Visitors to zoos can be a source of potential disturbance and stress to some captive, nonhuman animals in the wild. To determine the influence of visitor presence on captive bison (Bos gaurus gaurus), the study analyzed the behavior of 4 individuals at the Arignar Anna Zoological Park, India. The study often observed the behavior of the animals on visitor-present days and on days when visitors were absent. In the presence of zoo visitors, the bison showed a higher level of intragroup aggression and moving behavior. In contrast, the bison rested more when no visitors were present. The results revealed that the presence of zoo visitors significantly influenced the behavior of captive bison and thereby may have affected their welfare.

Siamangs (Hylobates syndactylus) and White-Cheeked Gibbons (Hylobates leucogenys) Show Few Behavioral Differences Related to Zoo Attendance

The effect of visitors on behavior and welfare of nonhuman animals in the zoo has been an active research topic during the last few decades. Although research has variously shown negative or positive impacts of zoo visitors on animals in captivity, previous primate research at Disney's Animal Kingdom® suggests the importance of visual barriers in allowing animals to cope with large crowds. Examining this further, this study monitored the behavior of white-cheeked gibbons (Hylobates leucogenys) and siamangs (Hylobates syndactylus) in large, open exhibits. Behavioral data showed rates of social behavior and percentage of time engaged in solitary behavior did not differ between low and high visitor-attendance days. Both gibbons and siamangs spent more time in areas away from the public on high attendance days. Supporting previous findings, results imply visual barriers and ability to retreat from crowds may have provided these animals with choice and minimized potential negative visitor impact. Future research should focus on the relationship between attendance and actual crowds at exhibits; it should utilize multi-institutional methodologies to control for variance and look for individual and demographic differences between individuals.     

Reactions of zoo visitors to free-ranging monkeys

This study assessed the potential of two types of primate exhibit both for enhancing zoo visitors' interest, knowledge, and enjoyment and for promoting conservation education. Visitors' reactions to a free-ranging group of cotton-top tamarins were compared with their responses to caged tamarins in three ways: 1) timing how long visitors spent at each exhibit, 2) recording the comments made by visitors about the exhibits, and 3) asking visitors to respond to questionnaires about the two exhibits. The results showed that the free-ranging group of tamarins provoked wider comment from members of the public than caged groups and that visitors were willing to spend much more time looking for and watching monkeys in trees than monkeys in cages. Visitors felt that improvements in the animals' welfare were obtained from allowing them to live free in the trees, thought that they could learn more from such groups than from caged animals, and enjoyed seeing the free-ranging tamarins more than the monkeys in cages. These results suggest that developing more naturalistic zoo exhibits can have considerable benefits not only for the animals involved, but also for public education in conservation issues. © 1994 Wiley-Liss, Inc.     

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.

Visitor Behaviors and Perceptions of Jaguar Activities

ABSTRACT

Zoo animals serve an important function in helping educate the public about their conservation needs. Despite this important function, little is understood about how visitors perceive different zoo exhibits and the animals that reside within them. In the present study, the behaviors displayed by two jaguars located at the Woodland Park Zoo were correlated with visitor behaviors and perceptions. Overall, visitors perceived their enjoyment to be lower when a jaguar was out of sight and rated the behavioral welfare of the jaguar to be lower when it was engaged in stereotypic behaviors. In addition, visitors who described a jaguar's behavior as stereotypic were significantly more likely to give lower ratings than those who perceived the jaguar to be active. It is suggested that by understanding how visitors perceive exhibited animals, zoos can address these perceptions in order to create more positive experiences for their visitors.     

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.

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.     

Female nile hippopotamus (Hippopotamus amphibius) space use in a naturalistic exhibit

Zoological institutions provide naturalistic exhibits for their animals in order to offer a more appealing look for visitors and give the animal the opportunity to engage in more natural behaviors. Examining space use of the animals in the naturalistic exhibit may aid in the management of these animals and inform future naturalistic exhibit design. The hippopotamus is an amphibious ungulate that spends much of its days in the wild in the water but may be found along the banks of the rivers basking in the sun. Our objective was to determine how captive female hippos utilize their exhibit by examining whether hippos selected for certain areas of a naturalistic exhibit. Scan sample data were collected on a group of nine captive female hippos housed at Disney's Animal Kingdom®. Using ArcView, the data were analyzed to determine distribution of hippos in the exhibit and their utilization of depth categories while in the water. Hippos were found to aggregate in preferred areas of the exhibit, mostly water, and selected most for water depths of 0.6–1.0 m. These results will aid in the understanding of hippopotamus space use and may aid zoological institutions in the design of naturalistic exhibits for hippos.

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.     

Behavior of the mayotte lemur,Lemur fulvus mayottensis,in captivity

A group of one male and two female Mayotte lemurs was observed at Chester Zoo, and their behaviors compared with published observations of wild populations of this and related forms of the brown lemur. It was found that the captive animals were active by both day and night, but that the pattern of activity was different from wild lemurs. The captive lemurs were less active than their wild counterparts and showed different timing of activity because of the feeding regimen at the zoo. The animals did not ignore the public at the zoo, but, on the contrary, directed some behaviors at the zoo visitors, particularly if the zoo visitors attempted to interact with the lemurs; under these conditions there was also an increase in the movements of the lemurs in the cage. Levels of aggression in the zoo lemurs were higher than those reported for wild populations, and aggression appeared to occur predominantly in the birth season. Levels of affiliative behaviors, particularly allogrooming, were comparable with those in the wild. Olfactory behaviors such as scent marking and anogenital sniffing also showed seasonal peaks and again appeared to occur at higher rates than in the wild.     

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.     

Variation in visitor perceptions of a polar bear enclosure based on the presence of natural vs. un-natural enrichment items

A debate exists among modern zoo staff as to whether or not the addition of un-naturalistic enrichment takes away from, or even defeats, the educational messages designers are trying to incorporate in naturalistic exhibits. A visitor study was conducted at the Central Park Zoo's polar bear exhibit in order to determine whether or not the type of enrichment in an enclosure actually alters guest perceptions. Visitors were exposed to one of two enrichment treatments in the bear enclosure: Naturalistic or Un-naturalistic. The results of this study suggest that enrichment type did not alter the perceptions of visitors. However, it did identify some of the different ways adults and youths perceive animals and zoos. Additionally, the study highlighted the varying perceptions individuals have of the concept of polar bears vs. their perceptions of the captive individuals at the Central Park Zoo. Implications for enrichment usage and exhibit design are discussed. Zoo Biol 28:292–306, 2009. © 2008 Wiley-Liss, Inc.     

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.     

The influence of environmental enrichment on Chinese visitor behavior

Welfare improvements for nonhuman animals should aim to satisfy the needs of visitors as well as those of the animals. Little research has been conducted, however, and existing work is confined to zoos in developed countries. This article reports the behavioral responses of Chinese visitors to environmental enrichment improvements in a zoo enclosure. Visit, viewing, and stopping behaviors significantly increased at the transformed exhibit, indicating that it provoked greater visitor interest. Furthermore, increased intragroup behaviors suggested that the exhibit probably motivated visitors to interact socially. The positive impact of the exhibit changes supports the enrichment efforts taking place in zoos around the world. The changes also provide encouragement for zoos in developing countries such as China because greater visitor interest provides a strong argument and an incentive for improving welfare standards.

Human–Ape Interactions in a Zoo Setting: Gorillas and Orangutans Modify Their Behavior Depending upon Human Familiarity

Understanding how human presence influences animal behavior, specifically the behavior of nonhuman primates, has important implications for methodology in cognitive and behavioral studies, for our understanding of human–animal relationships and for animal welfare in captive settings. Conducted in the San Diego Zoo, this study partially replicates an existing study on human–animal relationships, which focused on familiarity effects on the human-directed behavior of great apes residing in the Toronto Zoo. Such a replication in a new location and with different individuals is necessary to expand sample size and to better understand how ontogeny and living environment influence human-directed ape behavior. All-occurrence sampling of human-directed behavior was used to gather data on two gorilla groups and one orangutan group, all housed at the San Diego Zoo. The aim was to compare ape-initiated behaviors toward zoo staff with apeinitiated visitor-directed behavior, in accordance with predictions of the Human–Animal Relationship (HAR) model. Overall, human-directed behaviors were more frequent toward visitors than toward staff, mainly caused by increased visitor-directed visual behavior, specifically brief glances. Given that visual monitoring has been seen as fearful behavior, potentially related to predator monitoring, this would confirm the expectation that lack of familiarity will lead to increased visual vigilance. However, the visitor-directed visual behaviors may not be antagonistic or fearful. Considering the specific behaviors and exhibit designs, curiosity may be an equally likely explanation in this context. Aiming to also understand whether these groups exhibited species differences in human-directed behavior, it was found that orangutans engaged in more affiliative behavior overall than gorillas. Comparing our results with the previous study, we conclude that while effects of familiarity are present, those effects are modulated by both individual ontogeny and exhibit design. While the HAR model is partially supported, additional factors may need to be included to fully interpret the observed behavior. Additional research is needed to further understand the effects of species, sex, and ontogeny on the predictions of the HAR model.
