Comparison between 28 zoological parks: stereotypic and social behaviours of captive brown bears

In the present study we compared 33 enclosures in 28 parks, with a total of 66 bears. We chose direct observation of behaviour rather than surveys. Each enclosure was observed during one day; stereotypies and social relationships were qualitatively noted in types and amount. The connections of behaviour with bears characteristics and types of management […]

Wild Tigers in Captivity: A Study of the Effects of the Captive Environment on Tiger Behavior

Humans maintain wild animals in zoological parks for the purposes of education, conservation, research, and recreation. However, abnormal behaviors may develop in animals housed in human-made environments, if those environments do not allow them to carry out their natural behaviors (such as swimming, climbing, stalking, and predation). Captive environments in zoological parks often do not […]

Retreat space and human visitor density moderate undesirable behavior in petting zoo animals

This study focused on the relationship between nonhuman animal behavior and envi-ronment- specifically, between the undesirable behavior exhibited by domestic pet-ting zoo animals in the presence of humans and the spatial design of the petting zoo environment. A spatial feature of a petting zoo referred to as a retreat space was ma-nipulated so that it […]

Animal–visitor interactions in the modern zoo: Conflicts and interventions

Animal welfare, education, conservation, research, and entertainment are major goals of modern zoos, but they can be in conflict. For example, visitors enjoy learning about and observing natural behavior in captive animals, but visitors often want to observe and interact with the animals in close proximity. Unfortunately, proximity to and social interactions with humans induce […]

Preference for Structural Environmental Features in Captive Lowland Gorillas (Gorilla gorilla gorilla)

Increased interest in the behavioral effects of captive environments and advances in zoo design have resulted in a proliferation of “naturalistic” animal habitats. Although scientists have demonstrated that such exhibits have some positive effects on behavior, very little is known about the complex relationships between these specialized environments and behavior. This study sought to determine […]

Factors influencing the formation and maintenance of all-male gorilla groups in captivity

The social housing of males is of particular importance for captive managers of polygynous species. In this work, we highlight nine areas we believe are important to the successful formation and maintenance of all-male gorilla groups. Although more data are still needed to complete our understanding of these groups, the general picture that emerges is […]

Activity-based exhibition of five mammalian species: Evaluation of behavioral changes

Abstract 10.1002/zoo.10085.abs Activity-based management of captive animals involves the training and movement of animals among several exhibits and holding areas. We studied the effectiveness of this system in producing variation in behavior, controlling stereotypies, and eliciting natural behaviors. Twelve animals representing five species of mammals (orangutans, siamangs, tapirs, babirusa, and Sumatran and Siberian tigers) were […]

Orangutan use of vertical space in an innovative habitat

Abstract 10.1002/1098-2361(2000)19:43.3.CO;2-Z This study measured use of vertical space in an innovative habitat for three adolescent orangutans (Pongo pygmaeus). The indoor habitat was innovative in two main ways: a flooded floor and retractable skylights. It included four large molded trees and interwoven vines throughout 1,620 m3 of space. The exhibit was divided into four vertical […]

The reduction of stereotypic pacing in tigers (Panthera tigris) by obstructing the view of neighbouring individuals

Until recently, little attention has been focused on the influence of social interactions and the presence of conspecifics on stereotypic pacing in captive carnivores. This study examined the effect of adding a visual barrier between two tiger (Panthera tigris) exhibits on stereotypic pacing behaviour. Continuous sampling was used to record the duration of time tigers […]

Enriching the Lives of Zoo Animals, and their Welfare: Where Research can be Fundamental

As zoos have evolved, conservation and conservation education have become primary tasks. To achieve the maximum educational impact, zoos are enriching animal habitats so that their occupants display a wide range of activities that are attractive to the visitor, and unattractive activities are eliminated and reduced. Because public perceptions of the attractiveness of animal behaviour […]
