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...
Keeper/orangutan interactions at Auckland Zoo: Communication, friendship, and ethics between species
| Contributor(s):: Alexandra Palmer
This thesis is aimed at addressing debates within and beyond anthropology pertaining to humans' relationships with nonhuman great apes. Employing a hybrid methodology derived from ethnoprimatology, I use a combination of historical, ethnographic, and ethological data to examine...
Nest location preferences in zoo-housed orangutans
| Contributor(s):: Bastian, Meredith L., Glendinning, David R., Reddy, Alexandra J., Herrelko, Elizabeth S., Brown, Melba, Renner, Elizabeth, Thompson, Laurie
Nest building is an advanced and complex activity that wild orangutans engage in, yet they do so on a daily basis and with potential safety consequences. Like their wild counterparts, zoo-housed orangutans also make nests when given adequate materials, yet comparatively little research has...
Caregiver/orangutan relationships at Auckland Zoo: empathy, friendship, and ethics between species
| Contributor(s):: Palmer, A., Malone, N., Park, J.
Drawing on ethnographic, ethological, and historical data, we examined the relationships between orangutans and caregivers at Auckland Zoo. Caregivers displayed high levels of empathy and adjusted their husbandry routines to their interpretations of the orangutans' moods. Caregivers experienced...
The effect of zoo visitors on the behaviour and welfare of zoo mammals
| Contributor(s):: Alexandra Farrand
There is evidence that the presence of the visiting public affects the behaviour of zoo-housed mammals. Understanding the effect of visitors is important in improving animal welfare, achieving zoo conservation goals, increasing visitor education/entertainment, and facilitating interpretation of...
Post-occupancy Evaluation at the Zoo: Behavioral and Hormonal Indicators of Welfare in Orangutans (Pongo pygmaeus abelii)
| Contributor(s):: Leigha Tingey
An increased understanding of species-specific behavioral needs has lead zoos to focus on providing more naturalistic and stimulating environments. Scientific assessments of how changes in habitat affect animal behavior are necessary in improving overall animal welfare. This study examined the...

A case study of orangutan and siamang behavior within a mixed-species zoo exhibit
| Contributor(s):: Pearson, E. L., Davis, J. M., Litchfield, C. A.
This empirical case study assessed the behavior and welfare of 2 orangutans (Pongo abelii) and 2 siamangs (Symphalangus syndactylus) within a mixed-species zoo exhibit. The study used instantaneous scan-sampling to record behavior, location, and interspecies proximity over 174 hr and...
Empty nest: a case study of maternal response to separation from a juvenile offspring in a captive sumatran orangutan ( Pongo pygmaeus abelii )
| Contributor(s):: Tarou, L. R., Bashaw, M. J., Maple, T. L.
Improving the welfare of captive nonhuman primates requires evaluating the stressors created by the captive environment and reducing their negative effects. Social separation, although sometimes necessary for managing the genetic diversity of captive populations of animals, causes both...
Systematic investigation of the stability of food preferences in captive orangutans: implications for positive reinforcement training
| Contributor(s):: Clay, A. W., Bloomsmith, M. A., Marr, M. J., Maple, T. L.
Using preference-assessment tests with humans in conjunction with behavioral modification sessions has been a regular component of almost all operant conditioning programs with mentally challenged humans. This has been very effective in improving the efficiency of behavioral training in these...

Computer-assisted enrichment for zoo-housed orangutans ( Pongo pygmaeus )
| Contributor(s):: Tarou, L. R., Kuhar, C. W., Adcock, D., Bloomsmith, M. A., Maple, T. L.
The study of environmental enrichment has identified a variety of effective forms of enrichment, but there are widespread problems associated with their use. Few forms of enrichment are cognitively challenging, and even the most effective often result in rapid habituation. This study examined the...
Effects of browse, human visitors and noise on the behaviour of captive orangutans
| Contributor(s):: Birke, L.
This paper reports a study of the behaviour of captive orangutans (Pongo pygmaeus) at Chester Zoo, UK [date not given]. The study addressed two questions: what is the effect of the presence of fresh browse on the animals' behaviour and what is the effect of the presence of visitors? The first...
