Any legal trade in exotic species, whether wild-caught or captive-bred, usually leads to an increase in popularity and demand for the animals as "pets," a demand for which there are always people eager to supply the pet market to make a fast buck, usually at the animal's expense.

Here we show that stereotypy in captive Orange-Wing Amazon Parrots (Amazona amazonica) is correlated with poor performance on the same psychiatric task (the 'gambling task') as stereotypy in autistic and schizophrenic patients.

Abstract:
Dietary protein deficiency is considered a major obstacle in the evolution of highly specialized nectarivorous and frugivorous birds. Proposed physiological mechanisms that enable such specialists to subsist on low-protein diets include minimized endogenous protein losses, which contribute to reduced protein requirements. I compared these traits among nectarivorous red lories (Eos bornea), frugivorous Pesquet's parrots (Psittrichas fulgidus), and granivorous budgerigars (Melopsittacus undulatus). My results suggest that, relative to budgerigars, red lories and Pesquet's parrots have low endogenous protein losses and reduced crude protein (CP) requirements.
Based on nitrogen balance analyses, diets containing 1.0%, 3.2%, and 8.2% CP (on a dry matter (DM) basis) would meet the minimal protein requirements for maintenance for red lories, Pesquet's parrots, and budgerigars, respectively. Low endogenous protein losses and reduced protein requirements are effective physiological adaptations that allow birds such as red lories and Pesquet's parrots to specialize on low-protein foods.
