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 ...

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 ...

Most wild parrot species live in flocks, enriched by the environment and conspecific interactions. Captive parrots often live individually and are prone to behavioral maladaptation. If captive parrots and their behavior become intolerable, they are commonly relinquished to rescue organizations.

Personality predicts cognitive bias in captive psittacines, Amazona amazonica
Animal Behaviour, 2014The prevalence of stable behavioural differences between individuals of a species (i.e. personality) is puzzling because it indicates that there are limits on animals’ behavioural plasticity and, therefore, optimality of behaviour. Personality may result from individual state characteristics (e.g. morphology or physiology).

Mucoepidermoid Carcinoma in the Skull of an Orange-winged Amazon Parrot (Amazona amazonica)
Journal of Avian Medicine and Surgery, 2017A 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 ...
