Developmental Psychobiology, 2004
AbstractStereotypies are abnormal repetitive behaviors that often develop in animals housed in impoverished environments. Stereotypy represents the interaction of several complex developmental phenomena. To characterize the temporal nature of stereotypy increase (escalation) and decrease (attenuation), we monitored changes in stereotypy performance in ...

Phonation in the Orange-winged Amazon parrot,Amazona amazonica
Journal of Comparative Physiology ■ A, 1976The syrinx of the Orange-winged Amazon parrot includes two external tympaniform membranes thought to be involved in sound production. The position of these membranes at the confluence of the bronchial and tracheal lumina requires that during phonation they be driven by a single column of air and by its attending turbulence patterns.

Abstract 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.

Animal Cognition, 2013
Psittacines are generally considered to possess cognitive abilities comparable to those of primates. Most psittacine research has evaluated performance on standardized complex cognition tasks, but studies of basic cognitive processes are limited. We tested orange-winged Amazon parrots (Amazona amazonica) on a spatial foraging assessment, the Hamilton ...

VOCAL REPERTOIRE OF WILD BREEDING ORANGE-WINGED PARROTSAMAZONA AMAZONICAIN AMAZONIA
Bioacoustics, 2011ABSTRACT The vocal repertoire of Amazona amazonica during its breeding season has been recorded from wild individuals in Santa Barbara do Para, Para State, Brazil. At individual nests, we continuously recorded vocalizations and behaviour for four hours in the early morning and three hours in the late afternoon, three times a week throughout the ...

To establish reference intervals in orange-winged Amazon parrots ( Amazona amazonica ) for the complete blood count, plasma biochemical values, and lipid panel and to evaluate age- and sex-related variations, blood samples were obtained from 29 healthy juvenile and adult parrots.

Safe and effective sedation protocols are important for chemical restraint of birds in clinical and diagnostic procedures, such as clinical evaluations, radiographic positioning, and blood collection. These protocols may reduce stress and ease the management of wild-caught birds, which are susceptible to injury or death when exposed to stressful ...

Journal of Zoo and Wildlife Medicine, 2014
The objectives of this study were to optimize nested polymerase chain reaction (PCR) for Mycobacterium avium complex and Mycobacterium tuberculosis complex and apply them on samples from parrots. Results were negative for the presence of these Mycobacterium in the samples, and nested PCR was specific, faster, and more sensitive than other tests ...

Applied Animal Behaviour Science, 2010
Abstract 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 fount, and at the peak of the cage; interruption of ...
