The collared peccary (Pecari tajacu) is a species with great potential for breeding in captivity since it adapts well to a variety of foods, has a high breeding capacity and there is an existing market for its meat and leather, which is of excellent quality. However, it is necessary to understand...
How the rehabilitation of animals in captivity affects survival rates upon release : focus on a reintroduction project with Amazonas vinacea
Contributor(s):: Karen Burk
The topic of rehabilitation is of special importance when concerning animals that are near extinction. Biodiversity is the variety of animals, plants, their habitats and their genes. It is a key part of the functioning of the planet; if it is changed over a large scale then...

Environmental enrichment affects the fear and exploratory responses to novelty of young Amazon parrots
Contributor(s):: Meehan, C. L., Mench, J. A.
The development of techniques to reduce fear responses of captive animals is important because fear is generally considered an undesirable emotional state that is related to increased risk of injury and decreased biological functioning. We tested the effects of environmental enrichments designed...
Foraging opportunity and increased physical complexity both prevent and reduce psychogenic feather picking by young Amazon parrots
Contributor(s):: Meehan, C. L., Millam, J. R., Mench, J. A.
Although many authors have suggested that the quality of the cage environment contributes to the development and performance of psychogenic feather picking by parrots, there is little scientific evidence for this relationship. In chickens, there is an established relationship between absence of...
Preferences of Orange-winged Amazon parrots ( Amazona amazonica ) for cage enrichment devices
Contributor(s):: Kim, L. C., Garner, J. P., Millam, J. R.
Cage enrichment devices (ED), frequently termed cage "toys", are often provided to captive parrots as a means of promoting a behaviorally stimulating environment, but it is not clear whether particular properties of EDs are more effective than others in eliciting engagement with them. We tested...
Neonatal handling of Amazon parrots alters the stress response and immune function
Contributor(s):: Collette, J. C., Millam, J. R., Klasing, K. C., Wakenell, P. S.
The influence of neonatal handling on behaviour and immune function was assessed in Orange-winged Amazon parrots (Amazona amazonica). Chicks (n=11) were gently handled daily from 25 days of age until 38 days post-fledging, while control chicks (n=9) were not handled. At 10 days post-fledging...

Animism, cannibalism, and pet-keeping among the guaja of eastern amazonia
| Contributor(s):: Loretta A. Cormier
Recent work in Amazonian religion, sociality, and ecological adaptation have addressed the interrelationships among animism, cannibalism, and pet-keeping. In this article, I attempt to reconcile these works with the beliefs and behaviors of the Guajá of eastern Amazonia. I argue that the...

Over-sized pellets naturalize foraging time of captive Orange-winged Amazon parrots ( Amazona amazonica )
| Contributor(s):: Rozek, J. C., Danner, L. M., Stucky, P. A., Millam, J. R.
Parrots held in captivity experience distinctly different environmental demands, as compared to their wild conspecifics, particularly in regard to feeding. Cages equipped with computer-monitored infra-red beams (placed across a primary perch, in front of the feeder, in front of the drinking...
The effect of rope color, size and fray on environmental enrichment device interaction in male and female Orange-winged Amazon parrots ( Amazona amazonica )
| Contributor(s):: Webb, N. V., Famula, T. R., Millam, J. R.
Environmental enrichment devices (EDs; a.k.a. cage "toys") are often provided to captive parrots to mitigate the austerity of their environments, but the basis of attraction to EDs by parrots is poorly understood and many EDs go un-used. Preferences of Orange-winged Amazon parrots (Amazona...
Novelty and individual differences influence neophobia in orange-winged Amazon parrots ( Amazona amazonica )
| Contributor(s):: Fox, R. A., Millam, J. R.
Environmental enrichment both improves the welfare of captive animals and increases the validity of research using these animals. Enrichment programs have been shown to prevent or reduce the development of behavioral vices, stereotypy, and fearfulness. However, the protocols used in enrichment...
The effect of early environment on neophobia in orange-winged Amazon parrots ( Amazona amazonica )
Early experience is often a significant factor in shaping animals' later behaviour. Early maternal separation is associated with negative behavioral outcomes, such as increased fearfulness in rats, while higher levels of maternal grooming during the neonatal period are associated with decreased...
