A technique for isolating heterophils from blood of orange-winged Amazon parrots (Amazona amazonica amazonica)

Comparative Haematology International, 1997
Blood samples from adult orange-winged Amazon parrots (Amazona amazonica amazonica) were collected to develop a rapid and efficient technique for isolating pure populations of morphologically intact and functional heterophils. In addition, normal haematological parameters for the orange-winged Amazon parrots (n=20) were established and found to be ...

Bathing behavior of captive Orange-winged Amazon parrots (Amazona amazonica)

Applied Animal Behaviour Science, 2011
Abstract Feather maintenance behaviors, particularly preening and bathing, are nearly universal in birds, though their expression and function vary across species. Based on the rain-bathing style of wild Amazon parrots, parrots were sprayed with water to simulate rainfall, and subsequent bathing behavioral parameters were recorded as well as ...

THE NORMAL XERORADIOGRAPHIC AND RADIOGRAPHIC ANATOMY OF THE ORANGE‐WINGED AMAZON PARROT (AMAZONA AMAZONICA AMAZONICA)

Veterinary Radiology, 1990
The purpose of the study was to provide a reference for xeroradiographic and conventional radio‐graphic anatomy of the orange‐winged Amazon parrot (Amazona amazonica amazonica) as a representative of medium‐sized psittacine birds that are commonly kept as pets.

Effects of bilateral topical administration of repeated doses of rocuronium bromide as a mydriatic agent in Amazon parrots (Amazona aestiva and Amazona amazonica)

Journal of Exotic Pet Medicine, 2021
ABSTRACT The effects of bilateral topical application of repeated doses of rocuronium in parrots are unknown, motivating this research. These effects were evaluated in 24 healthy adult Amazon parrots (12 Amazona aestiva and 12 Amazona amazonica). Three different doses of rocuronium bromide (10 mg/mL) were applied with a micropipette onto the cornea ...

Flow cytometric quantitation of oxidative product formation by heterophils from orange-winged Amazon parrots (Amazona amazonica amazonica)

Comparative Haematology International, 1997
Oxidative metabolic burst activity by heterophils from orange-winged Amazon parrots (Amazona amazonica amazonica) was indirectly evaluated by measuring the oxidation of non-fluorescent intracellular 2′,7′-dichlorofluorescin (DCFH) to fluorescent 2′,7′-dichlorofluorescein (DCF) with flow cytometry.

Preferences of Orange-winged Amazon parrots (Amazona amazonica) for cage enrichment devices

Applied Animal Behaviour Science, 2009
Abstract 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.

Mucoepidermoid Carcinoma in the Skull of an Orange-winged Amazon Parrot (Amazona amazonica)

Journal of Avian Medicine and Surgery, 2017
A 33-year-old female intact orange-winged Amazon parrot (Amazona amazonica) presented for a slowly growing mass over the right eye. A computed tomography scan performed with and without intravenous contrast revealed a heterogeneous mixed soft tissue and mineral-dense mass with a small area of non-contrast-enhancing fluid density located between the ...

Phonation in the Orange-winged Amazon parrot,Amazona amazonica

Journal of Comparative Physiology ■ A, 1976
The 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.

Environmental enrichment and development of cage stereotypy in Orange‐winged Amazon parrots (Amazona amazonica)

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 ...

Novelty and individual differences influence neophobia in orange-winged Amazon parrots (Amazona amazonica)

Applied Animal Behaviour Science, 2007
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.
