  1. 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...

  2. Hair plucking in captive bonobos ( Pan paniscus)

    Contributor(s):: Brand, C. M., Marchant, L. F.

    Both wild and captive studies of grooming in non-human primates emphasize the adaptive role of this behavior. Indeed, social grooming is frequently characterized as "social glue" in the life of primates. Grooming behavior is studied to reveal dominance, kin relations, and social networks. Many...

  3. 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...

  4. A case study of primiparous maternal and infant gorilla ( Gorilla gorilla gorilla ) behavior

    Contributor(s):: Crosby, J. Y., Lukas, K. E.

    A primiparous mother and her infant were subjects of a longitudinal behavioral study at Lincoln Park Zoo in Chicago, Illinois. From November 1998 to November 1999, we collected a total of 100 hr of focal nonhuman animal instantaneous point sampling and all occurrence data on the mother and her...

  5. Behavioral responses of silverback gorillas ( Gorilla gorilla gorilla ) to videos

    Contributor(s):: Maloney, M. A., Leighty, K. A., Kuhar, C. W., Bettinger, T. L.

    This study examined the impact of video presentations on the behavior of 4 silverback, western lowland gorillas (Gorilla gorilla gorilla). On each of 5 occasions, gorillas viewed 6 types of videos (blue screen, humans, an all-male or mixed-sex group engaged in low activity, and an all-male or...

  6. Combination therapy reduces self-injurious behavior in a chimpanzee ( Pan troglodytes troglodytes ): a case report

    Contributor(s):: Bourgeois, S. R., Vazquez, M., Brasky, K.

    Self-injurious behavior (SIB) remains a severe and intractable abnormal behavior for nonhuman primates in diverse settings and is a significant concern for veterinarians and behavioral scientists. To date, no single pharmacological, behavioral, social, or environmental intervention method has...

  7. Effect of enclosure size and complexity on the behaviors of captive chimpanzees ( Pan troglodytes )

    Contributor(s):: Jensvold, M. L. A., Sanz, C. M., Fouts, R. S., Fouts, D. H.

    Reports describing the implementation of innovative facility designs are important to both the primate caregiving community and policymakers reviewing current U.S. Department of Agriculture regulations. This study documents the changes in behaviour of 5 adult chimpanzees that coincided with...

  8. 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...

  9. Positive reinforcement training as a technique to alter nonhuman primate behavior: quantitative assessments of effectiveness. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: Schapiro, S. J., Bloomsmith, M. A., Laule, G. E.

    Many suggest that operant conditioning techniques can be applied successfully to improve the behavioral management of nonhuman primates in research settings. However, relatively little empirical data exist to support this claim. This article is a review of several studies that discussed applied...

  10. Primate behavior studies: essential to primate welfare. Proceedings of the special Animal Behavior Society session, 2006

    Contributor(s):: Koch, V. W.

    This special issue contains 8 papers and 3 commentaries on the association between understanding nonhuman primate behaviour and providing for nonhuman primate welfare. The topics of the papers include: welfare of apes in captive environments; social housing for nonhuman primates in the research...

  11. The role of behavioral research in the conservation of chimpanzees and gorillas

    Contributor(s):: Lonsdorf, E. V.

    Chimpanzees and gorillas are among man's closest living relatives, sharing most of the human genetic code and having many similarities to humans in anatomy, physiology, and behavior. Like humans, these apes make and use tools and have strong family bonds. Chimpanzees even show population-specific...

  12. Welfare of apes in captive environments: comments on, and by, a specific group of apes

    Contributor(s):: Savage-Rumbaugh, S., Wamba, K., Wamba, P., Wamba, N.

    Accurately determining the proper captive environment for apes requires adequately assessing the psychological similarities between apes and humans. Scientists currently believe apes lack mental complexity (Millikan, 2006), raising questions concerning the evolution of human culture from ape-like...

  13. Empathy and donation behavior toward happy and sad chimpanzees

    Full-text: Available

    | Contributor(s):: Nils-Torge Telle, Hans-Radiger Pfister

    Past research indicates a moderate but robust relationship between human empathy and empathy toward animals. Further, it has been shown that human empathy is associated with more positive attitudes toward animals. What has not been researched, however, is human- and animal-directed empathy in...

  14. Assessing the prevalence and characteristics of hair-plucking behaviour in captive western lowland gorillas ( Gorilla gorilla gorilla)

    | Contributor(s):: Less, E. H., Kuhar, C. W., Lukas, K. E.

  15. A survey of the attitudes of stakeholders in the zoo industry towards the husbandry requirements of captive Great Apes

    | Contributor(s):: Fernie, A. C., Tribe, A., Murray, P. J., Lisle, A., Phillips, C. J. C.

  16. Chimpanzee ( Pan troglodytes ) responses to caregiver use of chimpanzee behaviors

    | Contributor(s):: Jensvold, M. L. A.

    The relationships between captive primates and their caregivers are critical ones and can affect animal welfare. Friendly relationships can improve quality of life; adversely, agonistic relationships can decrease quality of life. Caregivers in and of themselves should not be stressful to their...

  17. Conflict and reconciliation behavior trends of the bottlenose dolphin ( Tursiops truncatus )

    | Contributor(s):: Holobinko, A., Waring, G. H.

    Wild bottlenose dolphin (Tursiops truncatus) populations display societal structures characterized by numerous and frequent changes in group composition, complex social relationships, and high levels of cooperation, attributes also observed in human and nonhuman primate cultures. Maintaining...

  18. The domestication of social cognition in dogs

    | Contributor(s):: Hare, B., Brown, M., Williamson, C., Tomasello, M.

    Dogs are more skillful than great apes at a number of tasks in which they must read human communicative signals indicating the location of hidden food. In this study, we found that wolves who were raised by humans do not show these same skills, whereas domestic dog puppies only a few weeks old,...

  19. Psychopathology in great apes: concepts, treatment options and possible homologies to human psychiatric disorders

    | Contributor(s):: Brune, M., Brune-Cohrs, U., McGrew, W. C., Preuschoft, S.

  20. A note on enrichment for spontaneous tool use by chimpanzees ( Pan troglodytes )

    | Contributor(s):: Morimura, N.

    In the wild, decisions as to "when", "where", and "how" an animal acts are made based on the individual's own choice; in contrast, the behaviour of wild animals in captivity may be under human control. To improve the physical and psychological well-being of captive animals, we should ensure that...
