Behavioural response of zoo-housed Japanese macaques (Macaca fuscata) to changes in exhibit and social group

Moving animals to a new exhibit within a zoo is generally done with that animal’s well-being in mind. However, there are many factors that need to be considered when evaluating changes in well-being associated with environmental changes, such as the amount of time needed to habituate to the novel environment, and, for social animals, the […]

Habituation potential of yellow-eyed penguins depends on sex, character and previous experience with humans

Animal populations are increasingly challenged by anthropogenic environmental changes. Species, populations and individuals vary in their ability to cope with exposure to human proximity. However, little is known about what drives habituation or sensitization in wild populations. Via behavioural observations and heart rate telemetry during experimental disturbance, we determined the habituation potential of yellow-eyed penguins, […]

Bold, shy, and persistent: Variable coyote response to light and sound stimuli

To improve frightening device technology for managing predation, we examined variation in coyote (Canis latrans) response to visual, auditory, and combined stimuli using a behavior-contingent programmable frightening device. We hoped to gather information on the relative effectiveness of light, sound, and combined stimuli for deterring coyotes from a food resource. We exposed five pairs of […]

Maximizing the effectiveness of environmental enrichment: Suggestions from the experimental analysis of behavior☆

Environmental enrichment programs provide benefits to both captive animals and the facilities that house them, but cost time and resources to design, implement, and maintain. As yet, there have been few theoretically based guidelines to assist animal care staff in establishing cost-efficient enrichment methods that both elicit the desired behavioral changes and maintain their success […]

A single exposure to an acute stressor has lasting consequences for the hypothalamo–pituitary–adrenal response to stress in free-living birds

In vertebrates, activation of the hypothalamo–pituitary–adrenal (HPA) axis in response to unpredictable events results in elevated glucocorticoid secretion. Repeated exposure to stressors alters subsequent glucocorticoid secretion, either by inducing chronic stress or as a result of habituation. However, most studies of repeated stress focus on the impacts of multiple and frequent exposures to acute stressors, […]

Corticosterone responses of hand-reared and parent-reared grey-faced petrel chicks (Pterodroma macroptera gouldi)

Abstract 10.1002/zoo.20047.abs Hand-reared grey-faced petrel (Pterodroma macroptera gouldi) chicks (Order Procellariformes) that were subjected to a standardised blood sampling protocol immediately before they fledged showed a reduced corticosterone response compared to parent-raised chicks. Serum corticosterone concentrations were lower in hand-reared than parent-reared birds 30 and 60 min after handling was initiated (21.5±6.7 vs. 105.4±7.4 ng/ml […]

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 […]

Crate conditioning of bongo (Tragelaphus eurycerus) for veterinary and husbandry procedures at the Denver Zoological Gardens

Abstract 10.1002/(SICI)1098-2361(1998)17:13.3.CO;2-N Crate conditioning of bongo (Tragelaphus eurycerus) at the Denver Zoological Gardens made it possible to perform veterinary and husbandry procedures without chemical or manual restraint. Procedures included blood sampling, injections, wound treatment, milk collection, and caudal tail fold tuberculin testing. Habituation and positive reinforcement techniques were used to accomplish conditioning. The methods used […]

Conditioning of nyala (Tragelaphus angasi) to blood sampling in a crate with positive reinforcement

Abstract 10.1002/zoo.1430140307.abs Habituation and positive reinforcement procedures were successfully used for low stress blood sampling of nyala (Tragelaphus angasi) at the Denver Zoological Gardens. Four adult females and three offspring were conditioned with a food reward voluntarily to enter a plywood crate for bimonthly blood sampling from the rear leg. Habituated and conditioned, nonsedated nyala […]

Temperament, risk assessment and habituation to novelty in eastern chipmunks, Tamias striatus

An increasing number of studies are focusing on the role of animal temperament in the ecology of wild populations. One important step in these studies is to estimate the repeatability of temperament traits, by replicating measures of an animal’s behavioural or physiological reactions to a novel or stressful situation. When studies are performed in the […]
