Using radio frequency identification for behavioral monitoring in little blue penguins
Contributor(s):: Kalafut, Kathryn L., Kinley, Rickey
A common goal of captive animal institutions is to create environments that allow for the most naturalistic behavior from their animals. Behavioral data is often used as a measure of how an animal is thriving in its current environment. Obtaining this data can be very difficult and...
Environmental Enrichments for a Group of Captive Macaws: Low Interaction Does Not Mean Low Behavioral Changes
Contributor(s):: Reimer, Jéssica, Maia, Caroline Marques, Santos, Eliana Ferraz
Environmental enrichment has been widely used to improve conditions for nonhuman animals in captivity. However, there is no consensus about the best way to evaluate the success of enrichments. This study evaluated whether the proportion of time spent interacting with enrichments indicated the...
Visitor effects on zoo orangutans in two novel, naturalistic enclosures
Contributor(s):: Choo, Yuanting, Todd, Peter Alan, Li, Daiqin
Visitors are known to affect zoo animals, and such effects may be stressful, neutral, or enriching. The majority of research has focused on visitor number or visitor presence–absence, yet few studies have examined effects of other variables such as sound volume, visitor activity, and whether...
Stress and stress reduction in common marmosets
Contributor(s):: Kaplan, Gisela, Pines, Mathew K., Rogers, Lesley J.
Surprisingly few studies have measured cortisol levels in captive primates using samples collected during everyday life to gauge which activities and circumstances might induce or reduce stress. Much of what is behaviourally identifiable as stress may not to be reflected in physiological stress,...
The effect of different types of enrichment on the behaviour of cheetahs (Acinonyx jubatus) in captivity
Contributor(s):: Quirke, Thomas, O’ Riordan, Ruth M.
Enrichment, in the form of changes to the structure and content of enclosures, in addition to changes to husbandry practice, have been used on a range of felids resulting in increased activity levels and decreased levels of pacing behaviour. It is important to determine what types of enrichment...
The impact of exhibit type on behaviour of caged and free-ranging tamarins
Contributor(s):: Bryan, Kayley, Bremner-Harrison, Samantha, Price, Eluned, Wormell, Dominic
The lack of appropriate stimuli associated with captive environments has been documented to cause several behavioural and physiological issues in captive species, including loss of natural behaviours, psychopathologies and decreased reproductive success. Providing free-ranging, naturalistic...
Effects of captivity on house mice behaviour in a novel environment: Implications for conservation practices
Contributor(s):: Courtney Jones, Stephanie K., Munn, Adam J., Byrne, Phillip G.
Captive breeding programmes offer a method for preventing the extinction of threatened species, but often have difficulty establishing self-sustaining populations and generating individuals for release. This difficulty can arise because the behaviour of captive-reared animals differs from wild...
Effects of temporary captivity on ranging behaviour in urban red foxes (Vulpes vulpes)
Contributor(s):: Tolhurst, Bryony, Grogan, Adam, Hughes, Heather, Scott, Dawn
Temporary removal of wild animals from a resident territory has the potential to markedly impact subsequent ranging behaviour, and may negatively affect post-release welfare and survival. Admission of sick or injured wildlife into temporary captivity (termed ‘rehabilitation’) is a common practice...
Behavioral and spatial responses of captive coyotes to human activity
| Contributor(s):: Schultz, Jeffrey T., Young, Julie K.
Human interactions can alter an animal’s behavior and utilization of its surroundings, and how this impacts the welfare of some captive wild animals is of growing concern. Structural enrichment shelters offer weather protection, reprieve space from other animals or humans, or resting...
Determining the effects of duration and recency of exposure to environmental enrichment
| Contributor(s):: Ahlbeck Bergendahl, Ida, Salvanes, Anne Gro V., Braithwaite, Victoria A.
Experience can help animals adapt their behaviour to fit the environment or conditions that they find themselves in. Understanding how and when experience affects behaviour is important for the animals we rear in captivity. This is particularly true when we rear animals with the intent of...
Individual effects of seasonal changes, visitor density, and concurrent bear behavior on stereotypical behaviors in captive polar bears ( Ursus maritimus)
| Contributor(s):: Kelly, K. R., Harrison, M. L., Size, D. D., MacDonald, S. E.
Stereotypical behaviors in captive polar bears ( Ursus maritimus) can be detrimental to their welfare. These behaviors can be reduced through enrichment programs but are often not completely eliminated, so identifying potential triggers is important. The present study investigated the influences...
Post-copulative guarding: mating behaviour of non-territorial male sika deer ( Cervus nippon ) in an enclosure
| Contributor(s):: Endo, A., Doi, T., Shiraki, A.
The mating behaviour of 4 captive male sika deer, which had no territory or harem, was studied on Nozaki Island, Japan, during October 1990. The males were housed in an enclosure (0.32 square hectares) with 4 females and 1 male yearling. The dominance hierarchy of the males was recorded....
